Academic literature on the topic 'Pre-emergence flaming'

The demand for pesticide-free food has increased the need for sustainable organic farming. Onion (Allium cepa L.) is an important vegetable crop cultivated worldwide. The available weed control tools for intra-row weeds following onion emergence are limited. This study aimed to evaluate the potential use of liquefied petroleum gas (LPG) flaming as a pre- and post-emergence weed control method for both direct-seeded onion seedlings and transplanted onion bulbs. The safety of cross-row, where the flames are targeted to the intra-row area from both sides of the row, and broadcast flaming for bulb onion was compared. Cross-row flaming at twelve days after planting had no effect on onion dry weight, while broadcast flaming-treated plants’ dry weight was reduced by 36% as compared to controls. For the cross-row technique, the tested burners’ angle (45° and 30°) and inter-burner distances (30 and 40 cm) had no impact on weed control efficacy, and similar control levels, between 55% (15 cm) and 45% (10 cm), were observed 15 cm from both sides of the row-center. Direct-seeded onion cultivars were treated at various growth stages. The pre-crop-emergence stage was completely safe for the crop, and the second leaf stage exhibited a wide range of tolerance levels to flaming treatment across the different onion cultivars, with dry weights ranging between 39 and 117% compared to non-treated control in the flaming sensitive and tolerant cultivars, respectively. These results were validated under field conditions using the two most tolerant cultivars (Orlando and Browny); no yield reductions were observed for either cultivar when treated from the third leaf stage. In bulb onion, flaming had no impact on dry weight of shoots or roots when applied from four weeks after planting. This study demonstrates, for the first time, the potential of using flaming as a post-emergence weed control tool for direct-seeded and bulb onion, and at earlier time points than previously shown. Cross-row flaming proved effective for controlling intra-row weeds and can lower weeding costs. Future research should evaluate the safety of sequential applications and test complementary control methods for the initial growth stages.

Weed control in organic spinach for the processing market is challenging because of the low tolerance of weed contamination in the harvested produce and the limited physical weeding options. Optimisation of weed control systems is therefore urgently needed. Three field experiments with autumn spinach were carried out in organic fields to evaluate the impact of cultivar choice, seeding rate (300 and 400 seeds m−2), plant spacing management (10.5-cm-wide single rows and 21-cm-wide single or twin rows) and integrated weed management strategy (combinations of pre-sowing, pre-emergence and post-emergence tactics) on weed biomass and spinach yield and quality. Spinach cultivars with a planophile growth habit and a high growth rate were more weed suppressive than the cultivar with an erectophile growth habit and a slower growth rate. Spinach density was significantly negatively correlated with weed biomass and weed biomass fraction in the harvested produce, but significantly positively correlated with (marketable) spinach biomass and petiole fraction in the harvested produce. Narrow row spacing systems with post-emergence broadcast harrowing had the lowest weed biomass and weed biomass fraction but also the lowest (marketable) spinach biomass as a result of the thinning action of harrowing. Post-emergence harrowing is of key importance for reducing weed biomass in any integrated weed control strategy. Weediness was lowest in systems comprising flaming on false seedbed or in pre-emergence followed by post-emergence harrowing. To mitigate the risk of crop failure, the field should preferably be cropped with quickly growing spinach plants arranged in narrow spaced rows at high plant density and weeded by pre-sowing or pre-emergence flaming followed by post-emergence harrowing.

Weed competition during spears harvesting reduces asparagus yields. The application of herbicides during this period is illegal, and alternative non-chemical practices are needed. This research tested the effectiveness and efficiency of a custom-built combined flamer-cultivator to control weeds (both in the inter- and intra- spears production bands) during the spears harvest season. It also analysed the effects of various liquefied petroleum gas (LPG) doses on total asparagus yield, mean spear weight, and total number of marketable spears. In both years, the asparagus spears were generally not damaged by flame weeding using LPG doses of between 43 to 87 kg/ha. The same LPG doses were effective in controlling weeds, showing the same total marketable yields as the weed-free control. At high LPG doses (e.g. 130 and 260 kg/ha), yields decreased as a consequence of the damage caused to the spears, resulting in a lower number of marketable spears. Flaming did not affect the mean spear weight, and can be applied repeatedly during harvesting to maintain the weeds at a level that does not lead to a yield reduction. The repeated use of the combined flamer-cultivator (every seven days) led to higher yields than plots where weed control was not conducted. The new machine can be used in a period when herbicides are not possible. Flaming could be introduced by asparagus producers as an alternative, or in addition to herbicides applied in the pre-emergence and post-harvest of spears.

Weed control is a major challenge confronting growers transitioning to organic vegetable production. Organic standards require that growers manage weeds without synthetic herbicides while maintaining or enhancing soil quality. In 2005, we evaluated the effects of two seedbed preparation methods and six weed management tactics, compatible with organic standards, on soil quality indicators, weed pressure, and yield of edamame soybean [Glycine max (L.) Merrill]. Seedbed preparation was conducted with either a moldboard plow and roto-tiller or a spading machine. Weeds were managed by a) regular hand weeding, b) pre-emergent flaming, c) post-emergent incorporation of 100 g of corn gluten meal/m2, or weekly passes from crop emergence until row closure with d) a spring-tine weeder, e) a rolling cultivator, or f) a between-row flame weeder. Dominant weeds were smooth pigweed [Amaranthus hybridus (L.)], goosegrass [Eleusine indica (L.) Gaertn.], and giant crabgrass [Digitaria sanguinalis (L.) Scop.]. Smooth pigweed dominated in the corn gluten meal and spring-tine weeder treatments; goosegrass and giant crabgrass dominated in the two flamed treatments. Weed pressure was lowest, and crop yield highest, in the hand-weeded control and rolling cultivator treatments. Relative to these, crop yield was severely depressed by weed pressure in other treatments. The labile carbon concentration and enzymatic activity of soils was tested midseason, and at harvest, showed no significant treatment effects. Results suggest that the rolling cultivator offered the best weed control among the tactics tested, without adversely affecting soil quality.

IntroductionCirque du Soleil, the largest live entertainment company in the world, has eight standing shows in Las Vegas alone, KÀ, Love, Mystère, Zumanity, Believe, Michael Jackson ONE, Zarkana and O. Close to 150 million spectators have seen Cirque du Soleil shows since the company’s beginnings in 1984 and it is estimated that over 15 million spectators will see a Cirque du Soleil show in 2014 (Cirque du Soleil). The Cirque du Soleil concept of circus as a form of theatre, with simple, often archetypal, narrative arcs conveyed without words, virtuoso physicality with the circus artists presented as characters in a fictional world, cutting-edge lighting and visuals, extraordinary innovative staging, and the uptake of new technology for special effects can all be linked back to an early form of circus which is sometimes termed illegitimate circus. In the late 18th century and early 19th century, in the age of Romanticism, only two theatres in London, Covent Garden and Drury Lane, plus the summer theatre in the Haymarket, had royal patents allowing them to produce plays or text-based productions, and these were considered legitimate theatres. (These theatres retained this monopoly until the Theatre Regulation Act of 1843; Saxon 301.) Other circuses and theatres such as Astley’s Amphitheatre, which were precluded from performing text-based works by the terms of their licenses, have been termed illegitimate (Moody 1). Perversely, the effect of licensing venues in this way, instead of having the desired effect of enshrining some particular forms of expression and “casting all others beyond the cultural pale,” served instead to help to cultivate a different kind of theatrical landscape, “a theatrical terrain with a new, rich and varied dramatic ecology” (Reed 255). A fundamental change to the theatrical culture of London took place, and pivotal to “that transformation was the emergence of an illegitimate theatrical culture” (Moody 1) with circus at its heart. An innovative and different form of performance, a theatre of the body, featuring spectacle and athleticism emerged, with “a sensuous, spectacular aesthetic largely wordless except for the lyrics of songs” (Bratton 117).This writing sets out to explore some of the strong parallels between the aesthetic that emerged in this early illegitimate circus and the aesthetic of the Montreal-based, multi-billion dollar entertainment empire of Cirque du Soleil. Although it is not fighting against legal restrictions and can in no way be considered illegitimate, the circus of Cirque du Soleil can be seen to be the descendant of the early circus entrepreneurs and their illegitimate aesthetic which arose out of the desire to find ways to continue to attract audiences to their shows in spite of the restrictions of the licenses granted to them. BackgroundCircus has served as an inspiration for many innovatory theatre productions including Peter Brook’s Midsummer Night’s Dream (1970) and Tom Stoppard’s Jumpers (1972) as well as the earlier experiments of Meyerhold, Eisenstein, Mayakovsky and other Soviet directors of the 1920’s (Saxon 299). A. H. Saxon points out, however, that the relationship between circus and theatre is a long-standing one that begins in the late 18th century and the early 19th century, when circus itself was theatre (Saxon 299).Modern circus was founded in London in 1768 by an ex-cavalryman and his wife, Philip and Patty Astley, and consisted of spectacular stunt horse riding taking place in a ring, with acts from traditional fairs such as juggling, acrobatics, clowning and wire-walking inserted to cover the changeovers between riding acts. From the very first shows entry was by paid ticket only and the early history of circus was driven by innovative, risk-taking entrepreneurs such as Philip Astley, who indeed built so many new amphitheatres for his productions that he became known as Amphi-Philip (Jando). After years of legal tussles with the authorities concerning the legal status of this new entertainment, a limited license was finally granted in 1783 for Astley’s Amphitheatre. This license precluded the performing of plays, anything text-based, or anything which had a script that resembled a play. Instead the annual license granted allowed only for “public dancing and music” and “other public entertainments of like kind” (St. Leon 9).Corporeal Dramaturgy and TextIn the face of the ban on scripted text, illegitimate circus turned to the human body and privileged it as a means of dramatic expression. A resultant dramaturgy focusing on the expressive capabilities of the performers’ bodies emerged. “The primacy of rhetoric and the spoken word in legitimate drama gave way […] to a corporeal dramaturgy which privileged the galvanic, affective capacity of the human body as a vehicle of dramatic expression” (Moody 83). Moody proposes that the “iconography of illegitimacy participated in a broader cultural and scientific transformation in which the human body began to be understood as an eloquent compendium of visible signs” (83). Even though the company has the use of text and dramatic dialogue freely available to it, Cirque du Soleil, shares this investment in the bodies of the performers and their “galvanic, affective capacity” (83) to communicate with the audience directly without the use of a scripted text, and this remains a constant between the two forms of circus. Robert Lepage, the director of two Cirque du Soleil shows, KÀ (2004) and more recently Totem (2010), speaking about KÀ in 2004, said, “We wanted it to be an epic story told not with the use of words, but with the universal language of body movement” (Lepage cited in Fink).In accordance with David Graver’s system of classifying performers’ bodies, Cirque du Soleil’s productions most usually present performers’ ‘character bodies’ in which the performers are understood by spectators to be playing fictional roles or characters (Hurley n/p) and this was also the case with illegitimate circus which right from its very beginnings presented its performers within narratives in which the performers are understood to be playing characters. In Cirque du Soleil’s shows, as with illegitimate circus, this presentation of the performers’ character bodies is interspersed with acts “that emphasize the extraordinary training and physical skill of the performers, that is which draw attention to the ‘performer body’ but always within the context of an overall narrative” (Fricker n.p.).Insertion of Vital TextAfter audience feedback, text was eventually added into KÀ (2004) in the form of a pre-recorded prologue inserted to enable people to follow the narrative arc, and in the show Wintuk (2007) there are tales that are sung by Jim Comcoran (Leroux 126). Interestingly early illegitimate circus creators, in their efforts to circumvent the ban on using dramatic dialogue, often inserted text into their performances in similar ways to the methods Cirque du Soleil chose for KÀ and Wintuk. Illegitimate circus included dramatic recitatives accompanied by music to facilitate the following of the storyline (Moody 28) in the same way that Cirque du Soleil inserted a pre-recorded prologue to KÀ to enable audience members to understand the narrative. Performers in illegitimate circus often conveyed essential information to the audience as lyrics of songs (Bratton 117) in the same way that Jim Comcoran does in Wintuk. Dramaturgical StructuresAstley from his very first circus show in 1768 began to set his equestrian stunts within a narrative. Billy Button’s Ride to Brentford (1768), showed a tailor, a novice rider, mounting backwards, losing his belongings and being thrown off the horse when it bucks. The act ends with the tailor being chased around the ring by his horse (Schlicke 161). Early circus innovators, searching for dramaturgy for their shows drew on contemporary warfare, creating vivid physical enactments of contemporary battles. They also created a new dramatic form known as Hippodramas (literally ‘horse dramas’ from hippos the Attic Greek for Horse), a hybridization of melodrama and circus featuring the trick riding skills of the early circus pioneers. The narrative arcs chosen were often archetypal or sourced from well-known contemporary books or poems. As Moody writes, at the heart of many of these shows “lay an archetypal narrative of the villainous usurper finally defeated” (Moody 30).One of the first hippodramas, The Blood Red Knight, opened at Astley’s Amphitheatre in 1810.Presented in dumbshow, and interspersed with grand chivalric processions, the show featured Alphonso’s rescue of his wife Isabella from her imprisonment and forced marriage to the evil knight Sir Rowland and concluded with the spectacular, fiery destruction of the castle and Sir Rowland’s death. (Moody 69)Another later hippodrama, The Spectre Monarch and his Phantom Steed, or the Genii Horseman of the Air (1830) was set in China where the rightful prince was ousted by a Tartar usurper who entered into a pact with the Spectre Monarch and received,a magic ring, by aid of which his unlawful desires were instantly gratified. Virtue, predictably won out in the end, and the discomforted villain, in a final settling of accounts with his dread master was borne off through the air in a car of fire pursued by Daemon Horsemen above THE GREAT WALL OF CHINA. (Saxon 303)Karen Fricker writes of early Cirque du Soleil shows that “while plot is doubtless too strong a word, each of Cirque’s recent shows has a distinct concept or theme, that is urbanity for Saltimbanco; nomadism in Varekai (2002) and humanity’s clownish spirit for Corteo (2005), and tend to follow the same very basic storyline, which is not narrated in words but suggested by the staging that connects the individual acts” (Fricker n/p). Leroux describes the early Cirque du Soleil shows as following a “proverbial and well-worn ‘collective transformation trope’” (Leroux 122) whilst Peta Tait points out that the narrative arc of Cirque du Soleil “ might be summarized as an innocent protagonist, often female, helped by an older identity, seemingly male, to face a challenging journey or search for identity; more generally, old versus young” (Tait 128). However Leroux discerns an increasing interest in narrative devices such as action and plot in Cirque du Soleil’s Las Vegas productions (Leroux 122). Fricker points out that “with KÀ, what Cirque sought – and indeed found in Lepage’s staging – was to push this storytelling tendency further into full-fledged plot and character” (Fricker n/p). Telling a story without words, apart from the inserted prologue, means that the narrative arc of Kà is, however, very simple. A young prince and princess, twins in a mythical Far Eastern kingdom, are separated when a ceremonial occasion is interrupted by an attack by a tribe of enemy warriors. A variety of adventures follow, most involving perilous escapes from bad guys with flaming arrows and fierce-looking body tattoos. After many trials, a happy reunion arrives. (Isherwood)This increasing emphasis on developing a plot and a narrative arc positions Cirque as moving closer in dramaturgical aesthetic to illegitimate circus.Visual TechnologiesTo increase the visual excitement of its shows and compensate for the absence of spoken dialogue, illegitimate circus in the late 18th and early 19th century drew on contemporaneous and emerging visual technologies. Some of the new visual technologies that Astley’s used have been termed pre-cinematic, including the panorama (or diorama as it is sometimes called) and “the phantasmagoria and other visual machines… [which] expanded the means through which an audience could be addressed” (O’Quinn, Governance 312). The panorama or diorama ran in the same way that a film runs in an analogue camera, rolling between vertical rollers on either side of the stage. In Astley’s production The Siege and Storming of Seringapatam (1800) he used another effect almost equivalent to a modern day camera zoom-in by showing scenic back drops which, as they moved through time, progressively moved geographically closer to the battle. This meant that “the increasing enlargement of scale-each successive scene has a smaller geographic space-has a telescopic event. Although the size of the performance space remains constant, the spatial parameters of the spectacle become increasingly magnified” (O’Quinn, Governance 345). In KÀ, Robert Lepage experiments with “cinematographic stage storytelling on a very grand scale” (Fricker n.p.). A KÀ press release (2005) from Cirque du Soleil describes the show “as a cinematic journey of aerial adventure” (Cirque du Soleil). Cirque du Soleil worked with ground-breaking visual technologies in KÀ, developing an interactive projected set. This involves the performers controlling what happens to the projected environment in real time, with the projected scenery responding to their movements. The performers’ movements are tracked by an infra-red sensitive camera above the stage, and by computer software written by Interactive Production Designer Olger Förterer. “In essence, what we have is an intelligent set,” says Förterer. “And everything the audience sees is created by the computer” (Cirque du Soleil).Contemporary Technology Cutting edge technologies, many of which came directly from contemporaneous warfare, were introduced into the illegitimate circus performance space by Astley and his competitors. These included explosions using redfire, a new military explosive that combined “strontia, shellac and chlorate of potash, [which] produced […] spectacular flame effects” (Moody 28). Redfire was used for ‘blow-ups,’ the spectacular explosions often occurring at the end of the performance when the villain’s castle or hideout was destroyed. Cirque du Soleil is also drawing on contemporary military technology for performance projects. Sparked: A Live interaction between Humans and Quadcopters (2014) is a recent short film released by Cirque du Soleil, which features the theatrical use of drones. The new collaboration between Cirque du Soleil, ETH Zurich and Verity Studios uses 10 quadcopters disguised as animated lampshades which take to the air, “carrying out the kinds of complex synchronized dance manoeuvres we usually see from the circus' famed acrobats” (Huffington Post). This shows, as with early illegitimate circus, the quick theatrical uptake of contemporary technology originally developed for use in warfare.Innovative StagingArrighi writes that the performance space that Astley developed was a “completely new theatrical configuration that had not been seen in Western culture before… [and] included a circular ring (primarily for equestrian performance) and a raised theatre stage (for pantomime and burletta)” (177) joined together by ramps that were large enough and strong enough to allow horses to be ridden over them during performances. The stage at Astley’s Amphitheatre was said to be the largest in Europe measuring over 130 feet across. A proscenium arch was installed in 1818 which could be adjusted in full view of the audience with the stage opening changing anywhere in size from forty to sixty feet (Saxon 300). The staging evolved so that it had the capacity to be multi-level, involving “immense [moveable] platforms or floors, rising above each other, and extending the whole width of the stage” (Meisel 214). The ability to transform the stage by the use of draped and masked platforms which could be moved mechanically, proved central to the creation of the “new hybrid genre of swashbuckling melodramas on horseback, or ‘hippodramas’” (Kwint, Leisure 46). Foot soldiers and mounted cavalry would fight their way across the elaborate sets and the production would culminate with a big finale that usually featured a burning castle (Kwint, Legitimization 95). Cirque du Soleil’s investment in high-tech staging can be clearly seen in KÀ. Mark Swed writes that KÀ is, “the most lavish production in the history of Western theatre. It is surely the most technologically advanced” (Swed). With a production budget of $165 million (Swed), theatre designer Michael Fisher has replaced the conventional stage floor with two huge moveable performance platforms and five smaller platforms that appear to float above a gigantic pit descending 51 feet below floor level. One of the larger platforms is a tatami floor that moves backwards and forwards, the other platform is described by the New York Times as being the most thrilling performer in the show.The most consistently thrilling performer, perhaps appropriately, isn't even human: It's the giant slab of machinery that serves as one of the two stages designed by Mark Fisher. Here Mr. Lepage's ability to use a single emblem or image for a variety of dramatic purposes is magnified to epic proportions. Rising and falling with amazing speed and ease, spinning and tilting to a full vertical position, this huge, hydraulically powered game board is a sandy beach in one segment, a sheer cliff wall in another and a battleground, viewed from above, for the evening's exuberantly cinematic climax. (Isherwood)In the climax a vertical battle is fought by aerialists fighting up and down the surface of the sand stone cliff with defeated fighters portrayed as tumbling down the surface of the cliff into the depths of the pit below. Cirque du Soleil’s production entitled O, which phonetically is the French word eau meaning water, is a collaboration with director Franco Dragone that has been running at Las Vegas’ Bellagio Hotel since 1998. O has grossed over a billion dollars since it opened in 1998 (Sylt and Reid). It is an aquatic circus or an aquadrama. In 1804, Charles Dibdin, one of Astley’s rivals, taking advantage of the nearby New River, “added to the accoutrements of the Sadler’s Wells Theatre a tank three feet deep, ninety feet long and as wide as twenty-four feet which could be filled with water from the New River” (Hays and Nickolopoulou 171) Sadler’s Wells presented aquadramas depicting many reconstructions of famous naval battles. One of the first of these was The Siege of Gibraltar (1804) that used “117 ships designed by the Woolwich Dockyard shipwrights and capable of firing their guns” (Hays and Nickolopoulou 5). To represent the drowning Spanish sailors saved by the British, “Dibdin used children, ‘who were seen swimming and affecting to struggle with the waves’”(5).O (1998) is the first Cirque production to be performed in a proscenium arch theatre, with the pool installed behind the proscenium arch. “To light the water in the pool, a majority of the front lighting comes from a subterranean light tunnel (at the same level as the pool) which has eleven 4" thick Plexiglas windows that open along the downstage perimeter of the pool” (Lampert-Greaux). Accompanied by a live orchestra, performers dive into the 53 x 90 foot pool from on high, they swim underwater lit by lights installed in the subterranean light tunnel and they also perform on perforated platforms that rise up out of the water and turn the pool into a solid stage floor. In many respects, Cirque du Soleil can be seen to be the inheritors of the spectacular illegitimate circus of the 18th and 19th Century. The inheritance can be seen in Cirque du Soleil’s entrepreneurial daring, the corporeal dramaturgy privileging the affective power of the body over the use of words, in the performers presented primarily as character bodies, and in the delivering of essential text either as a prologue or as lyrics to songs. It can also be seen in Cirque du Soleil’s innovative staging design, the uptake of military based technology and the experimentation with cutting edge visual effects. Although re-invigorating the tradition and creating spectacular shows that in many respects are entirely of the moment, Cirque du Soleil’s aesthetic roots can be clearly seen to draw deeply on the inheritance of illegitimate circus.ReferencesBratton, Jacky. “Romantic Melodrama.” The Cambridge Companion to British Theatre 1730-1830.

Introduction One of the ways in which ‘country’ is made to work discursively is in ‘country music’ – defining a genre and sensibility in music production, marketing and consumption. This article seeks to excavate one small niche in the historical geography of country music to explore exactly how discursive antecedents emerged, and crucially, how images associated with ‘country’ surfaced and travelled internationally via one of the new ‘global’ media of the first half of the twentieth century – sheet music. My central arguments are twofold: first, that alongside aural qualities and lyrical content, the visual elements of sheet music were important and thus far have been under-acknowledged. Sheet music diffused the imagery connecting ‘country’ to music, to particular landscapes, and masculinities. In the literature on country music much emphasis has been placed on film, radio and television (Tichi; Peterson). Yet, sheet music was for several decades the most common way people bought personal copies of songs they liked and intended to play at home on piano, guitar or ukulele. This was particularly the case in Australia – geographically distant, and rarely included in international tours by American country music stars. Sheet music is thus a rich text to reveal the historical contours of ‘country’. My second and related argument is that that the possibilities for the globalising of ‘country’ were first explored in music. The idea of transnational discourses associated with ‘country’ and ‘rurality’ is relatively new (Cloke et al; Gorman-Murray et al; McCarthy), but in music we see early evidence of a globalising discourse of ‘country’ well ahead of the time period usually analysed. Accordingly, my focus is on the sheet music of country songs in Australia in the first half of the twentieth century and on how visual representations hybridised travelling themes to create a new vernacular ‘country’ in Australia. Creating ‘Country’ Music Country music, as its name suggests, is perceived as the music of rural areas, “defined in contrast to metropolitan norms” (Smith 301). However, the ‘naturalness’ of associations between country music and rurality belies a history of urban capitalism and the refinement of deliberate methods of marketing music through associated visual imagery. Early groups wore suits and dressed for urban audiences – but then altered appearances later, on the insistence of urban record companies, to emphasise rurality and cowboy heritage. Post-1950, ‘country’ came to replace ‘folk’ music as a marketing label, as the latter was considered to have too many communistic references (Hemphill 5), and the ethnic mixing of earlier folk styles was conveniently forgotten in the marketing of ‘country’ music as distinct from African American ‘race’ and ‘r and b’ music. Now an industry of its own with multinational headquarters in Nashville, country music is a ‘cash cow’ for entertainment corporations, with lower average production costs, considerable profit margins, and marketing advantages that stem from tropes of working class identity and ‘rural’ honesty (see Lewis; Arango). Another of country music’s associations is with American geography – and an imagined heartland in the colonial frontier of the American West. Slippages between ‘country’ and ‘western’ in music, film and dress enhance this. But historical fictions are masked: ‘purists’ argue that western dress and music have nothing to do with ‘country’ (see truewesternmusic.com), while recognition of the Spanish-Mexican, Native American and Hawaiian origins of ‘cowboy’ mythology is meagre (George-Warren and Freedman). Similarly, the highly international diffusion and adaptation of country music as it rose to prominence in the 1940s is frequently downplayed (Connell and Gibson), as are the destructive elements of colonialism and dispossession of indigenous peoples in frontier America (though Johnny Cash’s 1964 album The Ballads Of The American Indian: Bitter Tears was an exception). Adding to the above is the way ‘country’ operates discursively in music as a means to construct particular masculinities. Again, linked to rural imagery and the American frontier, the dominant masculinity is of rugged men wrestling nature, negotiating hardships and the pressures of family life. Country music valorises ‘heroic masculinities’ (Holt and Thompson), with echoes of earlier cowboy identities reverberating into contemporary performance through dress style, lyrical content and marketing imagery. The men of country music mythology live an isolated existence, working hard to earn an income for dependent families. Their music speaks to the triumph of hard work, honest values (meaning in this context a musical style, and lyrical concerns that are ‘down to earth’, ‘straightforward’ and ‘without pretence’) and physical strength, in spite of neglect from national governments and uncaring urban leaders. Country music has often come to be associated with conservative politics, heteronormativity, and whiteness (Gibson and Davidson), echoing the wider politics of ‘country’ – it is no coincidence, for example, that the slogan for the 2008 Republican National Convention in America was ‘country first’. And yet, throughout its history, country music has also enabled more diverse gender performances to emerge – from those emphasising (or bemoaning) domesticity; assertive femininity; creative negotiation of ‘country’ norms by gay men; and ‘alternative’ culture (captured in the marketing tag, ‘alt.country’); to those acknowledging white male victimhood, criminality (‘the outlaw’), vulnerability and cruelty (see Johnson; McCusker and Pecknold; Saucier). Despite dominant tropes of ‘honesty’, country music is far from transparent, standing for certain values and identities, and yet enabling the construction of diverse and contradictory others. Historical analysis is therefore required to trace the emergence of ‘country’ in music, as it travelled beyond America. A Note on Sheet Music as Media Source Sheet music was one of the main modes of distribution of music from the 1930s through to the 1950s – a formative period in which an eclectic group of otherwise distinct ‘hillbilly’ and ‘folk’ styles moved into a single genre identity, and after which vinyl singles and LP records with picture covers dominated. Sheet music was prevalent in everyday life: beyond radio, a hit song was one that was widely purchased as sheet music, while pianos and sheet music collections (stored in a piece of furniture called a ‘music canterbury’) in family homes were commonplace. Sheet music is in many respects preferable to recorded music as a form of evidence for historical analysis of country music. Picture LP covers did not arrive until the late 1950s (by which time rock and roll had surpassed country music). Until then, 78 rpm shellac discs, the main form of pre-recorded music, featured generic brown paper sleeves from the individual record companies, or city retail stores. Also, while radio was clearly central to the consumption of music in this period, it obviously also lacked the pictorial element that sheet music could provide. Sheet music bridged the music and printing industries – the latter already well-equipped with colour printing, graphic design and marketing tools. Sheet music was often literally crammed with information, providing the researcher with musical notation, lyrics, cover art and embedded advertisements – aural and visual texts combined. These multiple dimensions of sheet music proved useful here, for clues to the context of the music/media industries and geography of distribution (for instance, in addresses for publishers and sheet music retail shops). Moreover, most sheet music of the time used rich, sometimes exaggerated, images to convince passing shoppers to buy songs that they had possibly never heard. As sheet music required caricature rather than detail or historical accuracy, it enabled fantasy without distraction. In terms of representations of ‘country’, then, sheet music is perhaps even more evocative than film or television. Hundreds of sheet music items were collected for this research over several years, through deliberate searching (for instance, in library archives and specialist sheet music stores) and with some serendipity (for instance, when buying second hand sheet music in charity shops or garage sales). The collected material is probably not representative of all music available at the time – it is as much a specialised personal collection as a comprehensive survey. However, at least some material from all the major Australian country music performers of the time were found, and the resulting collection appears to be several times larger than that held currently by the National Library of Australia (from which some entries were sourced). All examples here are of songs written by, or cover art designed for Australian country music performers. For brevity’s sake, the following analysis of the sheet music follows a crudely chronological framework. Country Music in Australia Before ‘Country’ Country music did not ‘arrive’ in Australia from America as a fully-finished genre category; nor was Australia at the time without rural mythology or its own folk music traditions. Associations between Australian national identity, rurality and popular culture were entrenched in a period of intense creativity and renewed national pride in the decades prior to and after Federation in 1901. This period saw an outpouring of art, poetry, music and writing in new nationalist idiom, rooted in ‘the bush’ (though drawing heavily on Celtic expressions), and celebrating themes of mateship, rural adversity and ‘battlers’. By the turn of the twentieth century, such myths, invoked through memory and nostalgia, had already been popularised. Australia had a fully-established system of colonies, capital cities and state governments, and was highly urbanised. Yet the poetry, folk music and art, invariably set in rural locales, looked back to the early 1800s, romanticising bush characters and frontier events. The ‘bush ballad’ was a central and recurring motif, one that commentators have argued was distinctly, and essentially ‘Australian’ (Watson; Smith). Sheet music from this early period reflects the nationalistic, bush-orientated popular culture of the time: iconic Australian fauna and flora are prominent, and Australian folk culture is emphasised as ‘native’ (being the first era of cultural expressions from Australian-born residents). Pioneer life and achievements are celebrated. ‘Along the road to Gundagai’, for instance, was about an iconic Australian country town and depicted sheep droving along rustic trails with overhanging eucalypts. Male figures are either absent, or are depicted in situ as lone drovers in the archetypal ‘shepherd’ image, behind their flocks of sheep (Figure 1). Figure 1: No. 1 Magpie Ballads – The Pioneer (c1900) and Along the road to Gundagai (1923). Further colonial ruralities developed in Australia from the 1910s to 1940s, when agrarian values grew in the promotion of Australian agricultural exports. Australia ‘rode on the sheep’s back’ to industrialisation, and governments promoted rural development and inland migration. It was a period in which rural lifestyles were seen as superior to those in the crowded inner city, and government strategies sought to create a landed proletariat through post-war land settlement and farm allotment schemes. National security was said to rely on populating the inland with those of European descent, developing rural industries, and breeding a healthier and yet compliant population (Dufty), from which armies of war-ready men could be recruited in times of conflict. Popular culture served these national interests, and thus during these decades, when ‘hillbilly’ and other North American music forms were imported, they were transformed, adapted and reworked (as in other places such as Canada – see Lehr). There were definite parallels in the frontier narratives of the United States (Whiteoak), and several local adaptations followed: Tex Morton became Australia’s ‘Yodelling boundary rider’ and Gordon Parsons became ‘Australia’s yodelling bushman’. American songs were re-recorded and performed, and new original songs written with Australian lyrics, titles and themes. Visual imagery in sheet music built upon earlier folk/bush frontier themes to re-cast Australian pastoralism in a more settled, modernist and nationalist aesthetic; farms were places for the production of a robust nation. Where male figures were present on sheet music covers in the early twentieth century, they became more prominent in this period, and wore Akubras (Figure 2). The lyrics to John Ashe’s Growin’ the Golden Fleece (1952) exemplify this mix of Australian frontier imagery, new pastoralist/nationalist rhetoric, and the importation of American cowboy masculinity: Go west and take up sheep, man, North Queensland is the shot But if you don’t get rich, man, you’re sure to get dry rot Oh! Growin’ the golden fleece, battlin’ a-way out west Is bound to break your flamin’ heart, or else expand your chest… We westerners are handy, we can’t afford to crack Not while the whole darn’d country is riding on our back Figure 2: Eric Tutin’s Shearers’ Jamboree (1946). As in America, country music struck a chord because it emerged “at a point in history when the project of the creation and settlement of a new society was underway but had been neither completed nor abandoned” (Dyer 33). Governments pressed on with the colonial project of inland expansion in Australia, despite the theft of indigenous country this entailed, and popular culture such as music became a means to normalise and naturalise the process. Again, mutations of American western imagery, and particular iconic male figures were important, as in Roy Darling’s (1945) Overlander Trail (Figure 3): Wagon wheels are rolling on, and the days seem mighty long Clouds of heat-dust in the air, bawling cattle everywhere They’re on the overlander trail Where only sheer determination will prevail Men of Aussie with a job to do, they’ll stick and drive the cattle through And though they sweat they know they surely must Keep on the trail that winds a-head thro’ heat and dust All sons of Aussie and they will not fail. Sheet music depicted silhouetted men in cowboy hats on horses (either riding solo or in small groups), riding into sunsets or before looming mountain ranges. Music – an important part of popular culture in the 1940s – furthered the colonial project of invading, securing and transforming the Australian interior by normalising its agendas and providing it with heroic male characters, stirring tales and catchy tunes. Figure 3: ‘Roy Darling’s (1945) Overlander Trail and Smoky Dawson’s The Overlander’s Song (1946). ‘Country Music’ Becomes a (Globalised) Genre Further growth in Australian country music followed waves of popularity in the United States in the 1940s and 1950s, and was heavily influenced by new cross-media publicity opportunities. Radio shows expanded, and western TV shows such as Bonanza and On the Range fuelled a ‘golden age’. Australian performers such as Slim Dusty and Smokey Dawson rose to fame (see Fitzgerald and Hayward) in an era when rural-urban migration peaked. Sheet music reflected the further diffusion and adoption of American visual imagery: where male figures were present on sheet music covers, they became more prominent than before and wore Stetsons. Some were depicted as chiselled-faced but simple men, with plain clothing and square jaws. Others began to more enthusiastically embrace cowboy looks, with bandana neckerchiefs, rawhide waistcoats, embellished and harnessed tall shaft boots, pipe-edged western shirts with wide collars, smile pockets, snap fasteners and shotgun cuffs, and fringed leather jackets (Figure 4). Landscapes altered further too: cacti replaced eucalypts, and iconic ‘western’ imagery of dusty towns, deserts, mesas and buttes appeared (Figure 5). Any semblance of folk music’s appeal to rustic authenticity was jettisoned in favour of showmanship, as cowboy personas were constructed to maximise cinematic appeal. Figure 4: Al Dexter’s Pistol Packin’ Mama (1943) and Reg Lindsay’s (1954) Country and Western Song Album. Figure 5: Tim McNamara’s Hitching Post (1948) and Smoky Dawson’s Golden West Album (1951). Far from slavish mimicry of American culture, however, hybridisations were common. According to Australian music historian Graeme Smith (300): “Australian place names appear, seeking the same mythological resonance that American localisation evoked: hobos became bagmen […] cowboys become boundary riders.” Thus alongside reproductions of the musical notations of American songs by Lefty Frizzel, Roy Carter and Jimmie Rodgers were songs with localised themes by new Australian stars such as Reg Lindsay and Smoky Dawson: My curlyheaded buckaroo, My home way out back, and On the Murray Valley. On the cover of The square dance by the billabong (Figure 6) – the title of which itself was a conjunction of archetypal ‘country’ images from both America and Australia – a background of eucalypts and windmills frames dancers in classic 1940s western (American) garb. In the case of Tex Morton’s Beautiful Queensland (Figure 7), itself mutated from W. Lee O’Daniel’s Beautiful Texas (c1945), the sheet music instructed those playing the music that the ‘names of other states may be substituted for Queensland’. ‘Country’ music had become an established genre, with normative values, standardised images and themes and yet constituted a stylistic formula with enough polysemy to enable local adaptations and variations.

Conclusions In country music images of place and masculinity combine. In music, frontier landscapes are populated by rugged men living ‘on the range’ in neo-colonial attempts to tame the land and convert it to productive uses. This article has considered only one media – sheet music – in only one country (Australia) and in only one time period (1900-1950s). There is much more to say than was possible here about country music, place and gender – particularly recently, since ‘country’ has fragmented into several niches, and marketing of country music via cable television and the internet has ensued (see McCusker and Pecknold). My purpose here has been instead to explore the early origins of ‘country’ mythology in popular culture, through a media source rarely analysed. Images associated with ‘country’ travelled internationally via sheet music, immensely popular in the 1930s and 1940s before the advent of television. The visual elements of sheet music contributed to the popularisation and standardisation of genre expectations and appearances, and yet these too travelled and were adapted and varied in places like Australia which had their own colonial histories and folk music heritages. Evidenced here is how combinations of geographical and gender imagery embraced imported American cowboy imagery and adapted it to local markets and concerns. Australia saw itself as a modern rural utopia with export aspirations and a desire to secure permanence through taming and populating its inland. Sheet music reflected all this. So too, sheet music reveals the historical contours of ‘country’ as a transnational discourse – and the extent to which ‘country’ brought with it a clearly defined set of normative values, a somewhat exaggerated cowboy masculinity, and a remarkable capacity to be moulded to local circumstances. Well before later and more supposedly ‘global’ media such as the internet and television, the humble printed sheet of notated music was steadily shaping ‘country’ imagery, and an emergent international geography of cultural flows.

Possible areas of improving the efficiencies of the Lincoln University flame weeder are identified and investigated. The Hoffmann burner initially used in the Lincoln University flame weeder was found not to entrain sufficient air to allow complete combustion of the LPG used. A new burner, the Modified Lincoln University burner, was designed to improve the entrainment of air. Results show that the new design entrained sufficient air to theoretically allow complete combustion of the LPG, and this resulted in a 22.7% increase in heat output per Kg of LPG used over the Hoffmann burner. Temperature x time exposure constants required to kill weeds 0 - 15, 15 - 30, and 30 - 45 mm in size, were found to be respectively 750, 882, and 989 degrees Celsius.Seconds. These constants can be used to calculate the maximum speed of travel an operator can use a flame weeder at, once the temperature profile underneath its shields are established at various travel speeds, and therefore ensure that the flame weeder is used at its maximum efficiency. The constants can also be used to establish the cost efficiency of any flame weeder (in $/Ha), depending on the size of the weeds to be treated. The materials and methods used in establishing the temperature x time exposure constants can be used to establish the temperature x time exposure constant of any weed species at any size.
