8-381X Abstract. Formulation of the problem. One of the main tasks of production is reliable and trouble-free operation of equipment. In the oxygen-envelope process, when cast iron is purged, a large amount of carbon monoxide CO is emitted in the converter, which has a high temperature of more than 1 700 °С of the outgoing gases. The envelope gases in the waste heat boiler are cooled. Converter gas output is characterized by cyclic unevenness In this case, uneven heating of the walls of the boiler pipes occurs. By circulation pumps, chemically purified water is supplied for forced cooling of the boiler walls. When raising the outgoing gases, the cooling water is converted to pars by its subsequent supply to the consumer. The study is dedicated to solving the scientific and applied problem for the reasons for the formation of defects and the identification of cracks in the pipes of the recovery boiler.The purpose of the work. To investigate the causes of the development of transverse cracks in the pipelines of the recovery boiler by various methods of non-destructive testing, to use the methods of scanning microscopy to analyze the microstructure, mechanical tests, and the magnetic properties of structural carbon steel. Conclusions. One of the main reasons for the appearance of massive cracks in the pipes of cylindrical caissons is thermal fatigue caused by high thermal loads. Transverse cracks have the character of thermal fatigue failure, which is confirmed by changes in the ferrite-pearlite structure of the metal, resulting from uneven local cooling of the walls of the caisson. The reasons for the violation of the water circulation in the boiler are the pressure drop in the boiler and a sharp discharge, the load is the release of water from the boiler.

In this present works, a generalized approach for the two-phase flow analysis of a natural circulation in hybrid boiler. The model uses the combination of node and loop equations and the Newton Raphson technique for the solution of the set of equations. Loop equations have been developed for each evaporator tube with the unique driving force and pressure drop of the concerned loop. Node equations are mainly developed for common risers and downcomers. A unique connectivity matrix has been used to correlate each branch flow with loop and node equations. The model is validated by a unique indirect method by comparing the actual water level and calculated water level. Experiments have been performed with uniform diameter of tubes in 53 channels circulating loop to find the volume of steam. The model shows good agreement with experimental investigations with a maximum of 3.57% absolute error. The model can be used for the design, analysis, and optimization of the natural circulation network.

The paper presents the most important flow characteristics of low-pressure drop primary air nozzles used in circulating fluidized bed boilers. The role of an air nozzle pressure drop, pressure fluctuation, as well as air jet penetration length, orifice outlet jet kinetic energy and aerodynamic drag force of the gas outlet jet have been discussed. For the purpose of cold model studies the Lagisza 966MWth supercritical CFB boiler operating at the company TAURON Wytwarzanie SA, Poland has been chosen as the reference facility. In the experimental tests, three types of primary air nozzles with comparable static pressure drop and varied aerodynamic drag force have been tested. The experiments clearly showed that the pressure drop cannot be the only parameter characterizing the operation of the primary air nozzle and the air jet penetration length is determined primarily by the orifice outlet jet kinetic energy and not by the outlet jet velocity.

A high level of oxygen in boiler supply water would lead to oxidation corrosion of the boiler tubes. Reduction of the boiler tube thickness will affect its service life even result in such serious accidents as tube explosion. In S oil-field, a combining measure of physical and chemical methods were adopted to improve deaerator technology. A relatively complete ground deaeration process is formed. The deaeration system consists of water ring vaccum pump, deaeration tank, booster pump, circulating tank, etc. First softened water processed by softener would flow through 80 mesh stainless steel screen filter. Then in high vacuum deaeration tank, the water will be ejected in a spray due to the eddying flow of the nozzles and size of the droplet can reach 30 micrometer. Oxygen partial pressure in the tank is in a minimal level so that dissolved oxygen in the water-drops can be released. The steam and released oxygen will be sent to circulating tank for recycling. Deoxidation rate of the process can be above 95% and residual dissolved oxygen can be removed by chemicals. So the boiler supply water can meet technical requirements. The deaeration system has a good application in boiler supply water deaeration in S oil-field. Practical application shows the deaeration system has characteristics of stable performance, mainly maintenance-free, and good adaptability to some poor-quality water. So the deaeration system has a good promotion value.

In natural circulation loops, the driving force is usually low as it depends on the riser height which is generally of the order of a few meters. The heat transport capability of natural circulation loops (NCLs) is directly proportional to the flow rate it can generate. With low driving force, the straightforward way to enhance the flow is to reduce the frictional losses. A simple way to do this is to increase the loop diameter which can be easily adopted in pressure tube designs such as the AHWR and the natural circulation boilers employed in fossil-fuelled power plants. Further, the loop diameter also plays an important role on the stability behavior. An extensive experimental and theoretical investigation of the effect of loop diameter on the steady state and stability behavior of single- and two-phase natural circulation loops have been carried out and the results of this study are presented in this paper.

Based on the shear stress transport (SST) turbulence model, the influence of different outlet pipe angles on the head and efficiency of a boiler circulating pump was analyzed. When the outlet pipe angle changed from 115° to 130°, the head and efficiency of the pump reduced significantly. The boiler circulating pump with 115° outlet pipe angle was selected as the further research object, and the reliability of the numerical simulation was verified by experiments. The transient flow of the prototype pump under the design flow rate condition (1.0Qd) and four other flow rate conditions (0.6Qd, 0.8Qd, 1.2Qd, and 1.4Qd) was studied. The results show that, under the conditions of design flow and large flow rate (1.0Qd, 1.2Qd, and 1.4Qd), the centrality and regularity of radial force distribution are obviously better than those of small flow rate (0.6Qd, 0.8Qd). The leakage of the rear seal ring is less than that of the front seal ring under five flow rate conditions. As the flow rate increases, the leakage of front and rear seal rings decreases, and the leakage ratio of front and rear seal rings increases. The energy loss of the rear cover plate is greater than the energy loss of the front cover plate under five flow rate conditions. With the increase in flow rate, the total loss energy of the prototype pump decreases first and then increases, and the energy loss of the disc becomes larger and larger.

In this paper, a nondestructive inspection system is proposed to detect and quantitatively evaluate the size of the near- and far-side damages on the tube, membrane, and weld of the water-cooled wall in the fluidized bed boiler. The shape and size of the surface damages can be evaluated from the magnetic flux density distribution measured by the magnetic sensor array on one side from the center of the magnetizer. The magnetic sensors were arrayed on a curved shape probe according to the tube’s cross-sectional shape, membrane, and weld. On the other hand, the couplant was doped to the water-cooled wall, and a thin film was formed thereon by polyethylene terephthalate. Then, the measured signal of the flexible ultrasonic probe was used to detect and evaluate the depth of the damages. The combination of the magnetic and ultrasonic methods helps to detect and evaluate both near and far-side damages. Near-side damages with a minimum depth of 0.3 mm were detected, and the depth from the surface of the far-side damage was evaluated with a standard deviation of 0.089 mm.

Mechanical activation of the calcium-rich fly ash formed in circulating fluidized bed combustion (CFBC) boilers was investigated to enhance the compressive strength performance of the pastes. We studied the effect of the activation on the physical, chemical, and mineral characteristics of fly ash and its pastes. Our study shows that already a short mechanical activation yields a 10-fold improvement in the compressive strength of the pastes, reaching 60 MPa after 90 days of curing without any chemical activation or blending. Mechanical activation caused fragmentation of large porous aggregates in the raw ash enhancing the physical properties and reactivity of fly ash particles. Similarly to calcium sulfoaluminate cements, the mechanical strength was provided by the formation of abundant ettringite and possibly C-(A)-S-H gel-like phase that created a highly compact microstructure. Our findings suggest that mechanically activated Ca-rich CFBC fly ash can be successfully used as an alternative binder.

Abstract The research was conducted on the basis of four different types of hard coal and one type of brown coal. There are typical coals commonly used as fuel in Polish CFB boilers. The combustion process was conducted at a temperature of 850°C and the atmosphere of ambient air as well as in the mixture of oxygen and carbon dioxide in different proportions. The research was carried out using specially prepared cubical coal particles with measurements of 15×15mm and also 10×10 mm. The change of the mechanical properties was analyzed based on three parameters, i.e. compression strength, Vickers hardness and fracture toughness. The analysis was supplemented by microscopic images of the surface of the particles using an atomic force microscope. The results obtained clearly indicated the mechanical changes of the coal during its combustion, particularly at the moment of ignition of the char. Moreover, the results correlate very well with the processes of coal comminution that have been described by other authors (Basu, 1999; Chirone et al., 1991) during combustion in the circulating fluidized bed and also explain the sudden change of susceptibility to erosion in the conditions with and without combustion. The measured values can be used as strength parameters in the modelling of the mass loss of coal particles in conditions of circulating fluidized bed combustor that are hard to describe.

The aim of this study was to investigate the pyrogenic activity of factor(s) released by rat peritoneal macrophages following a brief stimulation with LPS. The effect of this factor on the number of circulating leukocytes and serum Fe, Cu and Zn levels, was also evaluated. The possibility that the content of interleukin (IL)-1β, IL-6 and tumour necrosis factor (TNF) in the supernatant could explain the observations was investigated. Supernatant produced over a period of 1 h by peritoneal macrophages, following a 30 min incubation with LPS at 37°C, was ultrafiltered through a 10 000 MW cut-off Amicon membrane, sterilized, and concentrated 2.5, 5, 10 and 20 times. The intravenous (i.v.) injection of this supernatant induced a concentration-dependent fever in rats with a maximal response at 2 h. The pyrogenic activity was produced by macrophages elicited with thioglycollate and by resident cells. The supernatants also induced neutrophilia and reduction in Fe and Zn 6 h after the injection. Absence of activity in boiled supernatants, or supernatants from macrophages incubated at 4°C with LPS, indicates that LPS was not responsible for the activity.In vitrotreatment with indomethacin (Indo), dexamethasone (Dex), or cycloheximide (Chx) did not modify the release of pyrogenic activity into the supernatant or its effects on the reduction in serum metal levels. Although Chx abolished the production of mediator(s) inducing neutrophilia, and Dex reduced the induction of IL-1β, TNF and IL-6, injection of the highest concentration of these cytokines detected in the supernatants did not induce fever.In vivotreatment with Dex, but not Indo, abolished the fever induced by the supernatant. These results suggest that macrophages contain pre-formed pyrogenic mediator(s), not related to IL-1β, IL-6 or TNF, that acts indirectly and independently of prostaglandtn. It also seems likely that the pyrogenic activity is related to the factor responsible for the reduction of serum Fe and Zn levels, but not the neutrophilia.

Abstract Tinakula is the first seafloor massive sulfide deposit described in the Jean Charcot troughs and is the first such deposit described in the Solomon Islands—on land or the seabed. The deposit is hosted by mafic (basaltic-andesitic) volcaniclastic rocks within a series of cinder cones along a single eruptive fissure. Extensive mapping and sampling by remotely operated vehicle, together with shallow drilling, provide insights into deposit geology and especially hydrothermal processes operating in the shallow subsurface. On the seafloor, mostly inactive chimneys and mounds cover an area of ~77,000 m2 and are partially buried by volcaniclastic sand. Mineralization is characterized by abundant barite- and sulfide-rich chimneys that formed by low-temperature (<250°C) venting over ~5,600 years. Barite-rich samples have high SiO2, Pb, and Hg contents; the sulfide chimneys are dominated by low-Fe sphalerite and are high in Cd, Ge, Sb, and Ag. Few high-temperature chimneys, including zoned chalcopyrite-sphalerite samples and rare massive chalcopyrite, are rich in As, Mo, In, and Au (up to 9.26 ppm), locally as visible gold. Below the seafloor, the mineralization includes buried intervals of sulfide-rich talus with disseminated sulfides in volcaniclastic rocks consisting mainly of lapillistone with minor tuffaceous beds and autobreccias. The volcaniclastic rocks are intensely altered and variably cemented by anhydrite with crosscutting sulfate (± minor sulfide) veins. Fluid inclusions in anhydrite and sphalerite from the footwall (to 19.3 m below seafloor; m b.s.f.) have trapping temperatures of up to 298°C with salinities close to, but slightly higher than, that of seawater (2.8–4.5 wt % NaCl equiv). These temperatures are 10° to 20°C lower than the minimum temperature of boiling at this depth (1,070–1,204 m below sea level; m b.s.l.), suggesting that the highest-temperature fluids boiled below the seafloor. The alteration is distributed in broadly conformable zones, expressed in order of increasing depth and temperature as (1) montmorillonite/nontronite, (2) nontronite + corrensite, (3) illite/smectite + pyrite, (4) illite/smectite + chamosite, and (5) chamosite + corrensite. Zones of argillic alteration are distinguished from chloritic alteration by large positive mass changes in K2O (enriched in illite/smectite), MgO (enriched in chamosite and corrensite), and Fe2O3 (enriched in pyrite associated with illite/smectite alteration). The δ18O and δD values of clay minerals confirm increasing temperature with depth, from 124° to 256°C, and interaction with seawater-dominated hydrothermal fluids at high water/rock ratios. Leaching of the volcanic host rocks and thermochemical reduction of seawater sulfate are the primary sources of sulfur, with δ34S values of sulfides, from –0.8 to 3.4‰, and those of sulfate minerals close to seawater sulfate, from 19.3 to 22.5‰. The mineralization and alteration at Tinakula are typical of a class of ancient massive sulfide deposits hosted mainly by permeable volcaniclastic rocks with broad, semiconformable alteration zones. Processes by which these deposits form have never been documented in modern seafloor massive sulfide systems, because they mostly develop below the seafloor. Our study shows how hydrothermal fluids can become focused within permeable rocks by progressive, low-temperature fluid circulation, leading to a large area (>150,000 m2) of alteration with reduced permeability close to the seafloor. In our model, overpressuring and fracturing of the sulfate- and clay-cemented volcaniclastic rocks produced the pathways for higher-temperature fluids to reach the seafloor, present now as sulfate-sulfide veins within the footwall. In the geologic record, the sulfate (anhydrite) is not preserved, leaving a broad zone of intense alteration with disseminated and stringer sulfides typical of this class of deposits.

A model to predict the steady-state behavior of a rectangular two-phase natural circulation loop has been proposed. The analysis employs a one-dimensional two-fluid model to identify various system parameters, with particular emphasis on the subcooled boiling region. The onset of two-phase region and point of net vapor generation and associated liquid temperatures and vapor qualities have been estimated using a few widely recognized correlations. Predicted results demonstrate that the consideration of subcooled boiling may have significant effect on system behavior, particularly around the transition regions. The interaction of saturated bubbles and subcooled liquid and associated change in heat transfer and frictional forces has been discussed in detail. Fluid stream has been observed to have different combinations of flow stream conditions at boiler exit and condenser inlet. Five probable combinations have been identified and a generalized working-regime map has been proposed on Nsub−NZu plane. Attempts have been made to identify the influence of various control parameters. A favorable sink condition (higher coolant flow rate or lower coolant entry temperature) has been found to be of particular importance to attain a wider operating range of wall heat flux and better heat transfer characteristics. A design map has been proposed to identify favorable operating condition in terms of control parameters to ensure complete condensation.

<p>Researches have been conducted into the causes of acidity of pulp formed in the system of circulating hydraulic ash and slag removal in thermal power plants (TPP) when using coals of Ekibastuz and Karaganda coal fields of the Republic of Kazakhstan. We have carried out a comparative study of combustion of Karazhyra and Maikube coals at the two RK TPPs with BKZ-75-39FB and BKZ-160-100FB steam boilers. For ash collection, wet ash collectors with remounted Venturi tube coagulators have been installed on TPP. In them, a chemical interaction of irrigating water with flue gases occurs, which include CO₂, SO₂, SO₃ and ash particles. The ash pulp formed moves to the pipeline, mixes with the slag pulp and is further transported along a tract to the ash dump. We have defined the relationship between the composition of the products of coal combustion and the formation of acidic pulp in the scrubber. Qualitative and quantitative composition of coals and their combustion products have been determined by the methods of X-ray and X-ray fluorescence analysis. As the analysis showed, the main components of ash and slag materials are the oxides SiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, K₂О, Na₂O. In the wet ash collectors gaseous substances present in flue gases, are dissolved and hydrolysed in irrigating water. While hydroremoving ash and slag, the compounds are dissolved in water and undergo hydrolysis. Oxides SiO₂, SO₂, TiO₂, P₂O₅ are hydrolyzed into acid, oxides CaO, MgO, K₂O and Na₂O – into base, Al₂O₃, Fe₂O₃– into amphoteric compounds. Chemical analysis of ash and slag pulp formed after Karazhyra coal combustion has been carried out. Calculation of the acidity of ash and slag material has been performed. Karazhyra coal ash is more acidic in nature. A lower content of amphoteric oxides in Maikube coal appears to be the cause of the pulp formation, with a higher pH. With X-ray diffraction method, the nature of combinations of metal oxides in the samples of coal, slag and ash have been determined. </p>

'The vital experience of the glad animal sensibilities made doubts impossible on the question of our speed; we heard our speed, we saw it, we felt it as a thrilling; and this speed was not the product of blind insensate agencies, that had no sympathy to give, but was incarnated in the fiery eyeballs of the noblest amongst brutes, in his dilated nostril, spasmodic muscles, and thunder-beating hoofs.' -- Thomas de Quincey (1849), "The English Mail-Coach" For Thomas de Quincey, the thrust of speed is intimately linked with the thrust of the body. Subjectivity is formed by and through a corporeal experience of acceleration. In this way, De Quincey has the jump on those other lovers of automated speed: the Italian Futurists. That heady clash of bodies, speed and information, or the technological sublime, we characteristically associate with the development of twentieth-century communication is already articulated some sixty years before Marinetti imagines the 'divine fusion' of body and machine. Thomas de Quincey's 1849 ode to the postal service -- "The English Mail Coach" -- functions as a significant text in modernity's velocity culture. Specifically, de Quincey allows us to historicise the critical terms of 'speed', 'body' and 'circulation'. This paper makes some preliminary historical observations about the acceleration of communication and transport systems and how this rapidity might give rise to new forms of subjectivity or the emergence of what Jeffrey T. Schnapp calls 'the kinematic subject'. The perceptual reconfiguration of time and space is central to an understanding of modernity's preoccupation with speed. Rapid data circulation through digital information systems means that distance appears to shrink and time seems to collapse. Manuel Castells calls this a 'new time regime' (429). Temporality now functions according to a double logic: a simultaneous binary of 'the eternal and of the ephemeral'. The contemporary 'manipulation of time' turns on 'instantaneity and eternity: me and the universe, the self and the net' (462-3). For David Harvey the defining feature of postmodernity is 'time-space compression'. Capitalism is 'characterised by speed-up in the pace of life, while so overcoming spatial barriers that the world sometimes seems to collapse inwards upon us' (241). Castells and Harvey are not, of course, the first to notice the degree to which the changing rhythms of a communication vehicle might impact upon perceptions of time and space. In 1909 Marinetti announces its demise: 'Time and Space died yesterday. We already live in the absolute, because we have created eternal, omnipresent speed'. Yet this death is prefigured some 120 years before by the 18th century author Hannah More in a letter where, quoting Alexander Pope, she illustrates her reaction to the introduction of the mail coach: I have just been thinking that if the amorous poet, who modestly wished to annihilate time and space had lived to see our fortunate days, he would have seen his prophetic visions realised... cards having well-nigh accomplished the first, and mail-coaches the last. (Qtd. in Lewis 264) This letter is dated 1788, only four years after the establishment of the mail coach system. Initially the service ran between London and Bristol so that Hannah More writing from Somerset would complain of being bypassed by this new mode of information circulation: Of the other blessing, the annihilation of space, I cannot partake; mail-coaches, which come to others, come not to me. Letters and newspapers, now that they travel in coaches like gentlemen and ladies, come not within ten miles of my hermitage. (265) More here identifies an important historical factor in the transformation of information networks. It concerns the coupling of transportation and communication: information travels 'in coaches like gentlemen and ladies'. In More's 18th century account the two remain connected while, as James Carey has noted, the significance of the 19th century's invention of the telegraph is that it splits the two processes. The telegraph 'allowed symbols to move independently of geography and independently of and faster than transport' (213). For de Quincey, a pivotal feature of the mail coach is the way in which communication and transportation function coextensively. Recounting his travels on the coach as it distributes news from the Napoleonic wars he notes that 'the grandest chapter of our experience, within the whole mail-coach service, was on those occasions when we went down from London with the news of victory' (290). For de Quincey, as for other commentators, the mail coach is a political instrument. Through the increasing efficiency of its communication infrastructure, it 'binds the nation together' (Austen 361). As de Quincey puts it 'the mail-coach, as the national organ for publishing these mighty events, thus diffusively influential, became itself a spiritualised and glorified object to an impassioned heart' (272). What impresses de Quincey most, however, is the speed of this vehicle. Or perhaps, more accurately, it is a particular relation between the self and speed, which confers on the mail coach a 'glory of motion' (270). By the time he publishes his essay, postal and newspaper circulation by mail-coach is nearly at an end. The last mail coach ceases action in London in 1846 (Daunton 123) and postal distribution begins to be carried out by rail. De Quincey clearly mourns the loss of this form of communication. And his regret depends on the self's perception of speed. That is, to qualify as an authentic act of transportation (of the body, of the post or of language), one must, to some degree, be aware of the systems of circulation, the modes of delivery and the vehicle of communication. One ought to be able to experience the speed at which one travels or the mail is delivered. The body must remain in contact with the message. In de Quincey's view the railway communication system fails for these sorts of reasons: The modern modes of travelling cannot compare with the mail-coach system in grandeur and power. They boast of more velocity, not however as a consciousness, but as a fact of our lifeless knowledge, resting upon alien evidence; as, for instance, because somebody says that we have gone fifty miles in the hour though we are far from feeling it as a personal experience ... . Apart from such an assertion, or such a result, I myself am little aware of the pace. But, seated on the old mail-coach, we needed no evidence out of ourselves to indicate the velocity. (283, emphasis in the original) Perched atop the careening mail coach, the self needs no secondary evidence to confirm its propulsion: 'we heard our speed, we saw it, we felt it as a thrilling'. But with the emergence of railway systems, the self somehow becomes cut off or distanced from the mode of transport: 'But now, on the new system of travelling, iron tubes and boilers have disconnected man's heart from the ministers of his locomotion' (284). To be sure, rail is faster. But that fails to impress de Quincey for the rail cannot offer him the same sublime effect. The mail coach is drawn by 'royal horses like cheetahs' (282) while the train lacks the power to raise even 'an extra bubble in a steam-kettle' (284). The sublimity of speed is also aural. But once again the railroad fails to inspire awe: 'the trumpet that once announced from afar the laurelled mail; heartshaking, when heard screaming on the wind ... has now given way for ever to the pot-wallopings of the boiler' (284). In Burke's formulation of the sublime there is danger and terror but there must also be a certain distance from this threat. It is 'simply painful' when we are aroused by causes that 'immediately affect us' but it is sublime when 'we have an idea of pain and danger, without being actually in such circumstances' (51) . For de Quincey sitting inside the carriage seems to offer too much safety and distance, the interior reserved as it is for the 'porcelain variety of the human race' (273). Instead, he travels aloft near the driver because of 'the air, the freedom of prospect, the proximity to the horses, the elevation of seat' (275). And he has the possibility of reining them in himself: 'the certain anticipation of purchasing occasional opportunities of driving' (275)1. The closer he is to the ministers of his locomotion, the better de Quincey likes it. The more he becomes the agent of his own speed, the more immediate, authentic and sublime seems his journey. For de Quincey, then, the superiority of the mail coach over the railroad lies not in terms of absolute speed but rather it concerns issues about the body's experience of and relation to that speed. As Matthew Schneider (1995) puts it 'the difference between the two with respect to their speed, privileges mail coaches by virtue of their violent immediacy, their ability to transmit the actual or living sensations rather than one that is intermediate or representational' (152)2. In a fascinating paper about the correlation between speed and subjectivity Jeffrey T. Schnapp identifies the mail coach in general and de Quincey in particular as emblematic of an 'inaugural moment' in the development of an 'anthropology of speed' (3). With a quick side swipe at the ahistorical and apocalyptic underpinning of Paul Virilio's Speed and Politics, Schnapp argues that although speed has always been 'an agent of individuation' it is with modernity that it begins to depend on the relation between self and vehicle: ... the mere experience of riding on horseback was not enough to establish a modern culture of velocity. Speed's rise as a cultural thematic, its move into an everyday realm of perceptibility, its adoption as sacrament of modern individualism, became possible only with the development of mechanical buffers between rider, horse, and roadway: buffers that enable new fantasies of attachment, first, between rider and engine, and, then, according to a more complex logic, between rider, engine, vehicle, and/or landscape. (10-1) What is particularly productive about Schnapp's account is that he schematises the history of transportation in terms of the relation between speed, body and vehicle. For Schnapp this is a pivotal dynamic. De Quincey's equestrian desire and his disdain for railroad travel, is part of a historical process where individuality comes to be 'identified with administration of one's own speed' (14). In Schnapp's model, there are 'two concurrent yet distinct experiences of velocity', one that he calls 'thrill-based' and the other 'commodity-based'. The first is experienced in modes such as on top of the mail-coach and later, cars, motorbikes and aeroplanes. 'Commodity-based' refers to train and bus travel. The difference between the two is that thrill-based transportation occurs when the passenger 'can envisage himself as the author of his velocity' while in 'commodity-based' forms the traveller is 'shielded from the natural environment and the engine, and passively submits himself to velocity' (18-9). De Quincey's essay is a valuable resource for communications historiography. Like Jacques Derrida, he recognises how the rhythms of the postal service function to construct identity. As a system of circulation and exchange, the post office institutionalises modes of correspondence, producing and regulating particular subjectivities. And like Postman Pat, de Quincey knows the corporeal pleasures of delivering the mail. Footnotes There are also issues of class at work here. Tickets were more expensive to sit inside the carriage which de Quincey, then a student at Oxford, could not afford. He attempts to reverse these class distinctions by arguing that 'inside which had been traditionally regarded as the only room tenantable by gentlemen, was, in fact, the coal-cellar in disguise' (187). The secondary material on de Quincey is quite extensive. In the last 15 years his work has been investigated from a number of different angles including poststructuralist approaches to language and his transitional status as a figure between Romanticism and Modernism.

The contemporary supermarket is a work of classification and cataloguing as marvellous as any museum. Barcodes are hallmarks by which its computer systems could know, in their own electronic language, every possible product of a certain kind afoot in the nation. It is a rather special institution in this respect -- a huge fund of contemporary synchronic cultural memory, a database and storehouse of collected human tastes to which individuals turn to seek out their own. However, this means that just as Wittgenstein demonstrated the impossibility of a purely private language, there can be no such thing as a purely private taste. Taste is demonstrated by choosing from a range of public items, that is, products. Therefore let's bracket the liberal concept of sovereign personal taste for now and beat a different track: the supermarket is the site of aggregation of multiple discourses by which the individual is sewn into and sews the fabric of collective life. Techniques used to sell food today, such as freebies (like plastic toys), free offers, forms of gambling, and images of healthiness, convenience, celebrity and enhanced relationships, appeal to -- must appeal to for commercial reasons -- shared values. It is inviting to view the supermarket as an emblem of a postmodern condition. The gaggle of images and words that line its aisles defy unity, play fast and loose with reality, create a simulacral space of copied quotes and sight bites that is coterminous with radically decentred selves. It conforms to the Jamesonian topography of a culture that has lost it -- that sense of real placed history that identity used to be tied up with. But my aim in this essay is to critique such a rhetoric of loss. Discourse remains the province of the self-imaginings of social groups in spite of the diversity of images in circulation. And although the media through which group solidarity is transmitted change with technological developments, the fact of such transmission does not. Hence, by looking at the imagery used on food packets, I will analyse the way that one rhetorical strategy used to sell the food we find on supermarket shelves -- nationalism -- is part of a longstanding cultural trajectory by which citizens of a nation imagine their relationship with their land. This, however, involves the equation of 'the nation' with the ethnic imagery of the group that dominates its political apparatus and territory, a process of circumscription that I shall ultimately suggest has political ramifications, especially in the context of nations like Australia which were formed by largely European settler colonisation of the land. Nationalism, then, is a strand of marketing rhetoric used most often, but not exclusively, for the promotion of products in the country of their origin. As such it grafts a tradition of art commemorating place and ethnic identity into the seemingly unlikely genre of the product label. Indeed, for Benedict Anderson the sociopolitical sentiment of nationalism requires forums and images through which to articulate itself, or more accurately, to imaginatively create its auratic object of adoration -- as nationalism is itself innovative (Anderson 15). It also depends upon technologies that can produce a sense of simultaneity between dispersed people who will never meet each other. The distribution of the packaged 'gifts' of a land to 'its people' provides one such opportunity for the transmission of sacralised images of land and the solidarity of its inhabitants. So the genre of the label that comes with a specific distribution and selling system provides the technical medium, and the land, its produce, its people and their relationships in ecosocial community, form the imagery. A limit case example of pride in the gifts of the land can be found on the label of New Zealand's Steinlager: "New Zealand's Finest ... World's Best Lager ... Brewed with the finest New Zealand Hops, Yeast, Barley and Pure Water ... Since 1854". It embodies a series of associations found in other examples: the products of the land are associated with firstly, high quality, and secondly, natural purity. New Zealand seems to be repeated with two slightly different senses. In its juxtaposition with "the world", the two places centre on the finished product of lager, which is presented as a literally world-beating national product. The last line of the label reads "Brewed and Bottled by New Zealand Breweries Limited", the company name both emphasising the agency of New Zealand people in processing ingredients taken from their land's soil, and the legally New Zealandian status of their enterprise. The second sense implies the physical basis for all this: the giftedness of the land which subtends an economy and a culture. "Since 1854" brings these components together on the axis of continuity, making the origination of national production temporal as well as spatial. In other words this benign relationship of production becomes part of national heritage. A certain double sense is in play. Land is both a nation comprising citizens and physical resource; the word that perfectly fuses the sense of the former's political proprietary relationship with the latter into a working unity. Accordingly many packets transfigure the legal requirement to mention the place of production into an attention-grabbing declaration of country of origin whilst also referring to the physical land. The latter may be parsed into two general categories: imagery of animals, plants, landscapes, the elements, etc, and rustic images of human management of the land. So Bulla ice cream advertises its Australianness to a pastoral backdrop; Saxa salt, which has been "Australia's own ... Since 1911", is being hauled by a hat-wearing Aussie man and loyal horse; Bundaberg caster sugar is both "pure Australian" and "Australian made" thanks to the blessing of the (Australian) sun. And other products, such as Australian Natural Foods Non Dairy Soy Mango Smoothie and Pureland Organic Tofu make links between nation and nature through 'land-based' company names similarly buttressed by images of Australian agricultural landscape and the Australian made hallmark respectively. The three conceptual categories often found in correlation with the concrete particulars of 'the land' -- healthiness, purity and naturalness -- are well represented in the packets analysed here. A series of metonymic implications is set up between the terms. They are all potential qualities of the land that are realised in the products it yields. Pureland and Australian Natural Foods juxtapose nation and healthiness closely and the pastoral visions of Bürgen and Dairy Vale have the approval of the National Heart Foundation. Bundaberg and Pureland make the most direct appeals to purity, but concepts such as Bulla's "Australian made real dairy" and Devondale's "choice grade" and "premium Australian" also convey a certain sense of uncorrupted pedigree in their products' provenance. Most products seem to evoke naturalness pictorially, with green rolling landscapes and cows feeding on the verdure featuring particularly highly. Thus at this point a critique of capitalist industrial culture is possible. The missing links are the contemporary factory and office: the places of the processing and assembly of the product physically and discursively; the places where the fruits of the land meet their packaging and are primed for the marketplace. The gifts of nature become commodities but are inscribed as the gifts of nature still, such that the point of sale obfuscates the point of production: profit. The whole enterprise seems to be based on a principle of distantiation. Because of urbanisation, the vast majority of people live away from farm land, and because most food is not consumed by the local communities that produce it, but is produced for larger markets, it is packed and written upon for transport to strangers who will buy it and perhaps also an idealisation of the land. Yet they aren't strangers. This mediation of group solidarity by food-as-commodity does not tear social bonds apart, it forms them. It forms ecosocial community just as it provides a projection of one. And the very invocation of group loyalty as the reason for buying means we should question, as John Frow has done, whether the commodity is always simply a token of abstraction in conceptual opposition to 'the gift' (Frow, "Gift and Commodity"). It is not simply the case that capitalists dupe consumers into thinking of commodities in gift-like terms. Indeed, the discourses of the land we find on supermarket shelves go back a long way in Western culture. As Raymond Williams says: "in English, 'country' is both a nation and a part of a 'land'; 'the country' can be the whole society or its rural area. In the long history of human settlements, this connection between the land from which directly or indirectly we all get our living and the achievements of human society has been deeply known" (1). The majority of the packets analysed extend the pastoral tradition of European art, a tradition which determines the "innate bounty" (33) of the land as the province of benign, 'total' social relations as reflected in the "timeless rhythm" of the authentic agrarian life (10). But the pastoral tradition is itself a media technical one. Williams points out that "a working country is hardly ever a landscape. The very idea of landscape implies separation and observation" (120). The same is true of pastoral in its nationalistic guise. It is transmitted by books, paintings and packets, is predicated on such a 'separation and observation'. The idealisation of the common land that subtends 'us' may be an attempt to bridge that distance, yet it is, ironically, transmitted through inscribed objects that create bonds between spatially and temporally dispersed people. It achieves what Anderson calls "unisonance", "a special kind of contemporaneous community which language alone suggests -- above all in the form of poetry and songs" (132). So, if the supermarket turns inner desire outward to the realm of public items that provides its possibilities, nationalistic desire moves in the same way, both inside and outside the supermarket context. There is no purely internal or purely external nation, just as there is no private language. Rather cultural memory, whether transmitted by a food packet or a poem is a thread transmitted through selves, language, technological milieux, and groups of people. Thus as Thongchai Winichakul succinctly states, "a nation is not a given reality. Rather it is the effect of imagining about it" (14). "We can know about it as long as we employ certain technologies to inscribe the possible sphere. In turn, such technologies create the knowledge of it, create a fact of it, and the entity comes into existence." (15). The contemporary food packet is one such media technology as certainly as a book or a song, and all media inscriptions of the possible sphere of 'the land' are lived ecosocial experience of the land. They make the land a unity by fusing its first physical sense with its second sociopolitical one. Invocation of the land as a prior given that subtends and provides the continuity of a sociopolitical group that has power over its resources, nests the historical contingency of that power relationship into a secure vision of the provenance of nation with the self-origination of 'its' land. That natural element, free, pure and healthy, is the one in which the group's ownership rights are rooted and legitimated. However, in fact, any nation is itself an historical innovation, an inherently unstable ideological product of strategy, technique, rhetorical and material. Nation-states are not naturally correlative with the land, nor are the ethnic groups that politically dominate the nation. They arise where other socio-economic political organisations existed before; they emerge. In The City and the Country Williams's main concern was to point out an alternative class-based history of the real and largely exploitative management of the land, a history that is actively occluded by idealised renderings of the countryside. Here in a parallel way but without room for explication, I want to suggest an alternative history of the management of the land that is indissociable from the emergence of the modern Australian nation -- a race-based history. Thus, here's the rub: the totems of pastoral that are equated with Australianness in the packets I have referred to, are European. The 'food packet' pastoral idealises group totems such as to transform historically contingent relationships of certain ethnic groups with the land into naturalised ones. The cows of Bulla and Devondale, the pastures of Dairy Vale, Bürgen's wheat, the agricultural infrastructure, the men imaged and their modes of management of the land, are European in lineage, and so is most of the food they sacralise as 'Australian'. These things are not natural to the land but were introduced, as was a related political and economic infrastructure that created 'Australia'. And there is a whole history to this appropriation of the land that is not active in the rhetorical force field of the European Australian pastoral, just as the living cultural memories of Aboriginal peoples disposed by the creation of the Australian nation-state are not. ... In "Australia Day at the Aboriginal Tent Embassy", Felicia Fletcher and John Leonard mention how representatives of Aboriginal countries in Australia assembled at Parliament House eat food to sustain themselves in their bid to right this dispossession: "vegetables are cooked in the coals, bread is toasted over the fire, endless cups of tea are poured, pots of three dozen eggs are boiled again and again to keep up the strengths and spirits of the people" (16). However, they add, quoting the group rather than a specific individual: "'It's nice, but at home we'd have a nice bit of kangaroo tail in the fire -- you've got to know how to do it properly -- and damper'": a different memory of and relationship with 'the land' (in both its senses). To conclude, the memories of the land create it at the time of commemoration. How we commemorate it is a present-day matter of great communal and political significance.

Michael Haneke’s film Caché tells the story of a bourgeois family in peril. The comfortable lives of the Laurents—husband Georges (Daniel Auteuil), wife Anne (Juliette Binoche), and teenage son Pierrot (Lester Makedonsky)—are disrupted when surveillance tapes of their home and private conversations are delivered to them anonymously. Ostensibly Caché sits in a familiar generic framework: the thriller narrative of a family under threat is reminiscent of films such as The Desperate Hours (1955), Cape Fear (1962), and Straw Dogs (1971). The weight of outside forces causes tension within the family dynamic and Georges spends much of the film playing detective (unravelling clues from the tapes and from his past). This framing draws us in; it is presumed that the mystery of the family’s harassment will finally be solved, and yet Haneke’s treatment of this material undermines viewer expectations. This paper examines the process of suspicious reading when applied to a film that encourages such a method, only to thwart the viewer’s attempts to come to a definitive meaning. I argue that Caché plays with generic expectations in order to critique the interpretive process, and consider what implications this has for suspicious readers. Caché positions us as detective. Throughout the film we follow Georges’s investigation to unravel the film’s central enigma: Who is sending the tapes? The answer to this, however, is never revealed. Instead viewers are left with more questions than answers; it seems that for every explanation there is a circumventing intricacy. This lack of narrative closure within the surface framework of a psychological thriller has proven fertile ground for critics, scholars, and home viewers alike as they painstakingly try to ascertain the elusive culprit. Character motives are scrutinised, performances are analysed, specific shots are dissected, and various theories have been canvassed. The viewer becomes ensnared in the hermeneutics of suspicion, a critical reading strategy that literary theorist Rita Felski has compared to the hard-boiled crime story, a scenario in which critic becomes detective, and text becomes criminal suspect to be “scrutinized, interrogated, and made to yield its hidden secrets” (224). Like Georges, the viewer becomes investigator, sifting through the available evidence in the vain hope that with scrupulous attention the film will surrender its mystery.Of course, Haneke is not unique in his withholding of a film’s enigma. David Lynch’s surreal neo-noir Lost Highway (1997) and Mulholland Drive (2001) have garnered a similar response and continue to be debated. Film scholar Mark Cousins compares Caché’s reception at Cannes to other landmark film and television examples:Where Dallas made people ask ‘who?’, Twin Peaks ‘what?’, the genre-bending films of the last decade ‘how?’ and The Crying Game was about the implications of the answer, Caché’s conversational buzz was more circular. Yes, we asked ‘who?’ Then, when it was clear this question was not answered by the film, we considered why it was not answered. (225–6)Felski’s meditation on the hermeneutics of suspicion touches on this issue, considering literary texts as preemptive of our mistrust. Extending Felski’s reasoning here as applicable to other forms of cultural expression, I would like to argue that Caché is a film that “matches and exceeds the critic’s own vigilance” for it is already involved in “subverting the self-evident, challenging the commonplace, [and] relentlessly questioning idées fixes and idées recus” (Felski 217). Caché challenges fixed and received ideas pertaining to audience expectations of the thriller film, subverting generic conventions that traditionally see the enigma resolved, the culprit apprehended, and order restored. More than simply refusing closure, Caché casts doubt on the very clues it offers up as evidence. Such a text performs “a meta-commentary on the traps of interpretation, a knowing anticipation and exposure of all possible hermeneutic blunders” (Felski 217). Throughout her essay, Felski highlights the lures and pitfalls of suspicious reading practices. Felski warns that attempts to gain mastery over texts by drawing to light purportedly obscured meanings are often as concerned with self-congratulatory demonstrations of skill in drawing hitherto unmade connections as they are with the texts themselves (230). While I do not wish to endorse suspicious reading as an unproblematic approach, the present paper considers what happens when readers encounter a text that seemingly cannot be approached in any other way. Unlike the realist literary narratives and mystery stories drawn on by Felski, Caché resists a manifest meaning in both form and content, making it nearly impossible for viewers not to search for latent meaning.So where are suspicious readers left when the texts interrogated refuse to bend to the demands placed on them? This is the question I will be examining in the remainder of this paper through the questions Caché poses and the care it takes in ensuring its enigmatic quality. I will proceed by breaking down what I believe to be the three possible avenues of response—Caché as impossible puzzle, inconclusive puzzle, or wrong puzzle—and their implications.I The Impossible Puzzle Caché opens with a static frame long take of a Parisian residential street. This could be mistaken for a still image until a pedestrian bustles past. A woman leaves her house centre frame. A cyclist turns the corner. “Well?” a male voice intones. “Nothing,” a female replies. The voices come from off-screen, and soon after the image is interrupted by fast forward lines, revealing that what we have been watching is not an image of the present moment but a video cassette of time already elapsed; the voices belong to our protagonists, Georges and Anne, commenting on its content and manipulating its playback. From the opening moments it becomes clear that we cannot be certain of what we are seeing or when we are seeing it.This presents an intriguing tension between form and content that complicates our attempts to gather evidence. Haneke pares back style in a manner reminiscent of the films of Robert Bresson or the work of the Italian neo-realists. Caché’s long takes, naturalistic lighting, and emphasis on the everyday suggest a realist aesthetic; the viewer can invest faith in these images because they ascribe to a familiar paradigm, one in which artifice is apparently minimal. This notion that a realist aesthetic equates to straightforward images is at odds, however, with both the thriller narrative (in which solutions must be concealed before they can be uncovered) and Haneke’s constant undermining of the ontology of the image; throughout the film, viewers will be disoriented by Haneke’s manipulation of time and space with unclear or retroactive distinctions between past, present, video, dream, memory, and reality.An additional contention might be the seemingly impossible placement of the hidden camera. In the same tape, Georges leaves the house and walks towards the camera, unaware of it. The shot indicates the camera must be elevated in the street, and at one point it appears that Georges is looking right at it. A later recording takes place in the apartment of Georges’s suspect, Majid. Viewers are given ample opportunity to scour the mise en scène to find what apparently is not there. Perhaps the camera is just too well hidden. But if this is not the case and we can neither locate nor conceive of the camera’s placement because it simply cannot be there, this would seem to break the rules of the game. If we are to formulate theories as to the culprit at large, what good is our evidence if it is unreliable? Viewers could stop here and conclude that a puzzle without a solution amounts to a film without a point. “Well?” Georges asks in the film’s opening. “Nothing,” Anne replies. Case closed. Short of giving up on a solution, one might conclude (as Antoine Doinel has) that those looking within the film for a perpetrator are looking in the wrong place. When the motives or opportunities of on-screen characters do not add up, perhaps it is Haneke one should turn to. Those familiar with Haneke’s earlier film Funny Games (1997) will know he is not afraid to break the tacit rules by which we suspend our disbelief if there is a point to be made. Film scholar David Sorfa concludes it is in fact the audience who send the tapes; Caché’s narrative is fuelled by the desire of viewers who want to see a film (102). Tempting though these solutions might be (Georges does not see the camera because he is a fictional character in a film unaware of its creator), as critic Roger Ebert has pointed out, such theories render both the film’s content, and any analysis of it, without purpose: It introduces a wild card. It essentially means that no analysis of the film is relevant, because nothing need make sense and no character actions need be significant. Therefore, the film would have the appearance of a whodunit but with no who and no dunnit. (“Caché: A Riddle”)The Caché as impossible puzzle avenue leaves the suspicious reader without reason to engage. If there can be no reward for our efforts, we are left without incentive. Alternately, if we conclude that Haneke is but the puppet master sadistically toying with his characters, we are left at a similar juncture; our critical enquiry has all the consequence of the trite “but it was all a dream…” scenario. “Well?” “Nothing.” I suspect there is more to Caché than that. A film so explicit in its stimulation of suspicious reading seems to merit our engagement. However, this is not to say that our attention will be satisfied with the neatly tied up solution we might expect. II The Inconclusive Puzzle When, one evening, Pierrot does not come home as expected, Georges and Anne conclude the boy has been kidnapped. They interpret their son’s absence as an escalation in the “campaign of terror” that had hitherto consisted of surveillance videos, odd phone calls, and childlike but portent drawings. With police assistance, Georges goes to confront his suspect, Majid. An Algerian boy from his childhood, now middle aged and disadvantaged because of lies Georges told as a child, Majid has already (quite convincingly) denied any knowledge of the tapes. At the door they meet Majid’s son who is equally perplexed at the accusation of kidnapping. The pair are arrested and an exhausted Georges returns home to explain the situation to his wife:Georges: So now they’re both in the cage for the night.Anne: And then?Georges: Then they’ll let them go. If there’s no proof, they have to. There’s suspicion, nothing more.The next day a sullen Pierrot returns home, having stayed the night at a friend’s without notifying his parents. His clear disdain for his mother is revealed as he rejects her affection and accuses her of having an affair. Pierrot likewise treats his father with disinterest, raising viewer suspicion that he might have a motive for tormenting his parents with the videotapes. Pierrot is just one cog in the family’s internal mechanism of suspicion, however. Whether or not Anne is actually having an affair can only be speculated; she denies it, but other scenes open the way to our suspicion. Anne is rightly suspicious of Georges’s reluctance to be open about his past as his proclivity to lie is gradually revealed. In short, Haneke deliberately layers the film with complexity and ambiguity; numerous characters could be implicated, and many questions are raised but few are answered.This suggests that suspicious readers might have recourse to Haneke as author of the text. Haneke, however, celebrates Caché’s ambiguity and his decision to leave the film open: “The truth is always hidden…that’s how it is in the real world. We never, ever know what the truth is. There are a thousand versions of the truth. It depends on your point of view” (Haneke). In interview, Haneke’s language also raises suspicion. At times he speaks knowingly (refusing to reveal important dialogue that occurs in the film’s final shot—an extreme long shot, the characters too distant to be heard), and at other times he seems as uncertain as his viewers (commenting on Anne’s denial of an affair, Haneke remarks “I believe her because she plays it very seriously. But you never know”) (Haneke).Despite this reluctance to offer explanations, Haneke’s status as an auteur with recurring concerns and an ever-developing vision prompts suspicious readers to evaluate Caché in light of his greater oeuvre. Those suspecting Pierrot of wanting to punish his parents might find their theory bolstered by Benny’s Video (1992), Haneke’s film about a teenage boy who murders a friend and then turns in his parents to the police for helping him cover it up. Furthermore, Das Weiße Band (The White Ribbon, 2009) is set in a small German village on the eve of World War One and the narrative strongly suggests the town’s children are responsible for a series of malicious crimes. Whilst malign children in Haneke’s other works cannot explain Caché’s mystery, his oeuvre provides a greater context in which to consider the film, and regenerates discussion as viewers look for patterns in the subject matter Haneke chooses to explore. Regarding Caché as an inconclusive puzzle shifts the emphasis from a neatly packaged solution to a renewable process of discovery. To suggest that there is an answer to be found in the text, a culprit who escapes apprehension but is at least present to be caught, gives suspicious readers cause to engage and re-engage. It is to assume that the film is not without a point. Close attention may reward us with meaningful nuances that colour our interpretation. Haneke’s obsessive attention to detail also seems to suggest that nothing on screen is accidental or arbitrary, that our concentration is warranted, and that active viewing is a necessity even if our expectations and desires for closure may not be granted.Caché ends without revealing its secret. Georges’s suspect Majid has committed suicide (perhaps due to the trauma dredged up by Georges’s accusations), Majid’s son has confronted Georges at his work place (“I wondered how it feels, a man’s life on your conscience?”), and Georges has refused any responsibility for his actions in the distant and recent past. Of the film’s conclusion, cinema theorist Martine Beugnet writes:In the end […] we watch him draw the curtains, take a sleeping pill and go to bed: an emphatic way of signifying the closure of an episode, the return to normality—the conclusion of the film. Yet the images ‘refuse’ to comply: behind the closing credits, the questioning gaze not only persists but affirms its capacity to reinvent itself. (230)The images Beugnet is referring to are the two final shots, which are both static long takes. The first is an extreme long shot, taken from the darkness of a barn into the bright courtyard of the family estate of Georges’s childhood. A child (Majid) is forcibly removed from the home and taken away in a car (presumably to an orphanage due to the lies told by a jealous Georges). This shot is followed by the film’s closing shot, another extreme long shot, this time of the front steps of Pierrot’s school. The frame is cluttered with children and parents, and our eyes are not directed anywhere in particular. Some viewers will notice Pierrot chatting with Majid’s son (a potentially revealing conversation that cannot be heard), others will not see the two young men hidden in the crowd. Eventually the credits roll over this image.Georges’s attempts to shut out the world seem undermined by these images, as Beugnet writes they “‘refuse’ to comply” to this notion of conclusion. Instead of bringing closure to the narrative, they raise more questions. What and when are they? One cannot be sure. The first shot may be a dream or a memory; its placement after a shot of Georges going to bed might encourage us to connect the two. The second shot at the school could be more surveillance footage, or possibly another dream. It might imply the boys have conspired together. It might imply Majid’s son is confronting Pierrot with information about his father. It could be interpreted as the end of the narrative, but it could also be the beginning. Some read it as threatening, others as hopeful. It might imply so many things. However, this “questioning gaze” that persists and reinvents itself is not just the gaze of the film. It is also the gaze of the suspicious reader. From the initial hype upon the film’s Cannes release in 2005, to the various theories circulating in online forums, to Ebert’s scrupulous re-evaluation of the film’s enigma in 2010, to the ever developing body of scholarly work on Haneke’s films, it seems Caché’s mileage for suspicious readers is still running strong, not least because “whodunit?” may be the wrong question.III The Wrong PuzzleOliver C. Speck has remarked that Caché is “Haneke’s most accessible film, but also the most densely layered,” leading the viewer “on a search for clues that always ends in frustration” (97). For Ebert, the film’s lack of resolution leaves the viewer “feeling as the characters feel, uneasy, violated, spied upon, surrounded by faceless observers” (“Caché”). Cousins likewise comments on the process Caché instigates: The film structures our experience in a generically gripping way but then the structure melts away at the moment when it should most cohere, requiring us to look back along its length (the structure’s length and the film’s) to work out where we went wrong. But we did not go wrong. We went where we were told to go, we took the hand of the narrative that, in the final stages, slipped away, leaving us without co-ordinates. (226)The "whodunit” of Caché cannot be definitively proven. Ultimately, viewers can have suspicion, nothing more. So where are we left as suspicious readers when texts such as Caché surpass our own critical vigilance? We can throw in the towel and claim that an impossible puzzle does not deserve our efforts. We can accept that the text has out-played us; it is an inconclusive but compelling puzzle that does not provide enough links in the hermeneutic chain for us to find the closure we seek. Alternately, when the answer is not forthcoming, we can hypothesise that perhaps we have been asking the wrong question; whodunit is beside the point, simply a Hitchcockian MacGuffin (the object or objective that the protagonists seek) introduced to bait us into confronting much more important questions. Perhaps instead we should be asking what Caché can tell us about colonial histories, guilt, vision, or the ontology of cinema itself.This is the avenue many scholars have taken, and the avenue Haneke (rather than his film necessarily) would have us take. The “who did what, when, why, and how” might be regarded as beside the point. In an interview with Andrew O’Hehir, Haneke is quoted:These superficial questions are the glue that holds the spectator in place, and they allow me to raise underlying questions that they have to grapple with. It’s relatively unimportant who sent the tapes, but by engaging with that the viewer must engage questions that are far less banal.Catherine Wheatley agrees, arguing Caché’s open ending renders the epistemological questions of the guilty party and their motives irrelevant, giving preference to questions raised by how this chain of events affect Georges, and by extension the viewer (163–4). By refusing to divulge its secrets, Caché both incites and critiques the interpretive process, encouraging us to take up the role of detective only to anticipate and exceed our investigative efforts. Caché’s subversion of the self-evident is as much a means to launch its thriller narrative as it is a way of calling into question our very understanding of what “self-evident” means. Where Felski describes suspicious interpretations of realist texts (those that attempt to unmask the ideologies concealed behind an illusion of transparency and totality), from its opening moments, Caché is already and constantly unmasking itself. The film’s resistance of a superficial reading seems to make suspicious interpretation inevitable. Wherever viewer suspicion is directed, however, it relies on engagement. Without reason to engage, viewers are left with an impossible puzzle where critical involvement and attention is of no consequence. “Who is sending the tapes?” may be an unimportant or unanswerable question, but it must always be a valid one. It is this query that incites and fuels the interpretive process. As there can only ever be suspicion, nothing more, perhaps it is the question rather than “the answer” that is of utmost significance.Works CitedBeugnet, Martine. “Blind Spot.” Screen 48.2 (2007): 227–31.Benny’s Video.
