‘The want of a proper Gardiner’: late Georgian Scottish botanic gardeners as intermediaries of medical and scientific knowledge

Often overlooked by historians, specialist gardeners with an expert understanding of both native and exotic plant material were central to the teaching and research activities of university botanic gardens. In this article various interrelationships in the late Georgian period will be examined: between the gardener, the garden, the botanic collection, the medical school and ways of knowing. Foregrounding gardeners’ narratives will shed light on the ways in which botanic material was gathered and utilized for teaching and research purposes, particularly for medical students, as well as highlighting the importance of the garden as a repository of botanic material for the classroom. In thisway, the blurred lines between art and science, skill and scholarly activity, and shared pedagogic practices between botany and anatomy will be revealed.


Introduction
In 1754 William Cullen, at that time professor of medicine, and Robert Hamilton, Regius Professor of Botany and Anatomy, complained about the lack of a decent botanic garden at the University of Glasgow.Their proposal, which concerned the 'great garden', was to reconfigure it, making it 'more useful to the study of Botany'. 1 At the same time, they stressed the need for 'getting a good gardiner'. 2The importance of a 'good' gardener was outlined in more detail in their memorial (a petition), directed to the honourable rector and other members of the University of Glasgow.As well as bemoaning the current state of decay of the fruit trees, the nature of the soil and its 'situation very much exposed to the smoke and the soot of the town', they argued that the university should 'take the proper measures for planting their Garden in a manner becoming a Society devoted to Taste and Science'. 3They concluded by affirming that 'on this occasion we cannot avoid observing that the study of Botany in this University has been very much retarded by the want of a proper Gardiner & that the present appointments are insufficient for engaging one'. 4Nothing, however, came of the petition and Glasgow did not succeed in creating the type of botanic garden desired by Hamilton and Cullen until 1817 when the impetus was driven by Glaswegian citizens led by Thomas Hopkirk, with joint funding from the university, and subscribers of the Royal Botanic Institution of Glasgow. 5 Nonetheless, the petition does highlight two interrelated issues that go to the heart of this article.First, it emphasizes the central role that good or 'proper gardeners' played in achieving a state-of-the-art garden in terms of planting and garden management.Second, it highlights the importance of a botanic garden that was simultaneously fashionable, ornamental and scientific in nature, thus revealing its dual purpose as both a teaching and civic space within the city. 6he eighteenth century can be seen as a transitional period in terms of both the design and use of university botanic gardens.This is best illustrated by turning to John Hope (professor of botany and materia medica and the King's Botanist) and his Edinburgh University garden, created in the 1760s on Leith Walk, which was well financed by Parliament. 7Hope's garden marked the change from the regular and formal design of traditional university physic gardens, with their central purpose as medicinal teaching spaces, to more picturesque and taxonomically arranged collections.This new type of garden further encompassed more economic and exotic botanic specimens as they arrived in Britain from around the globe.With its growing collection obtained from exploratory voyages, the garden also attracted a broader range of visitors and users, from the serious student to the merely curious.Indeed, in 1782 Hope even had to introduce a ticketing system to regulate visitors, due in part to the fashionable interest in botany in this period.The Caledonian Mercury recorded that 'by this regulation it is not meant to render access to the Garden difficult.Strangers, the Gentlemen of this county, the citizens of Edinburgh, and any person of knowledge or curiosity upon sending their names (taxonomically organized collections of trees) in the nineteenth century.They examine how financial concerns forced botanical societies to attract subscribers and paying visitors.As a result, 'there was pressure to apply the principles and practices of landscape gardening to create visually attractive spaces'. 10This tension emerges in the late eighteenth century as aesthetic landscape principles were implemented in botanic gardens to attract casual visitors and subscribers, sometimes to the obfuscation of the scientific and medical roles of the botanic garden.Johnson describes how at Glasnevin, Dublin, the garden became 'a contested space, where the divergent views of the expert and amateur made their presence felt'. 11Similarly at Oxford, John Sibthorp, as Sherardian Professor of Botany, argued that despite their inferiority of 'Magnificence and Splendour' compared to those given royal financial backing, academic botanic gardens were more useful as 'their Object [was] to inform as well as amuse'. 12He went on to state that 'Picturesque Beauty is not merely considered, but method & order as far as they conduct to a systematic arrangement must be preserved'. 13This delineates the connections between finance and botanic collections, which will be explored in more detail later, as well as the distinction Sibthorp perceived between the picturesque on the one hand and method and order on the other.This relationship between science and aesthetics builds particularly upon the work of Nuala Johnson, who has expertly discussed these connections in relation to the botanic gardens of Cambridge, Belfast and Dublin, particularly during the nineteenth century. 14he real significance of the 1777 plan of John Hope's Leith Walk garden (Figure 1) in Edinburgh lay, then, in its attempt to combine scholarly order with picturesque beauty rather than to draw a line between the two.This in turn expanded the role of the gardener.In this new garden the traditional formal beds growing medicinal plants, which were central to earlier physic garden design, were moved to one side.Instead the main body of the garden was laid out with shrubs, flowers and trees according to both taxonomic order, particularly the Linnaean system, and the picturesque design principles of the day, which were implemented in the serpentine paths winding between beds. 15At the centre of this landscape, combining 'order and beauty', was the large glasshouse with its exotic specimens, whilst just outside the walls there was an experimental field growing the economically valuable crop of rhubarb. 16This physical manifestation, displaying both formal and picturesque elements, was complemented with a transition in pedagogical methods from teaching botany through multi-sensory engagement to an approach that favoured the visual over the other senses.In his lectures Hope argued that the most important senses for students to develop were taste and smell.Yet it is clear that in his teaching he also utilized visual methods, such as specially commissioned large teaching diagrams, the demonstration of plant experiments, and the facilitation of close observation of plant dissections.Individual students conducted these dissections using specimens provided by the gardener.
Margaret Maria Olszewski has expertly discussed this move towards the preference of the visual in botanic teaching in reference to the introduction of botanical models in the mid-nineteenth century.As well as making teaching more engaging and easier for large groups of students, she argues that there were also financial savings.As the professor 'would have been responsible for paying assistants' wages, a collection of easy-to-use materials that required no assistants … was an economically sound investment'. 17lszewski also notes that there would have been savings in not having to gather specimens from the garden on an almost daily basis for teaching purposes.Again, economic concerns are important factors to consider and one of the reasons Hope was able to create such an expensive teaching resource was his ability to gain extra financing from government for his enterprise. 18This in turn allowed him to maintain a large staff of gardeners who could facilitate the multi-sensory pedagogical approach to botanic teaching that he favoured.As Noltie notes, Hope's large collection of teaching drawings indicate a belief in the value of visual material even though this is not explicitly recorded in his lecture notes.Instead they seem to have been employed alongside, rather than eclipsing, education through the other senses. 19he interrelationship between the gardener and the physical space and its activities can be seen in this letter from Thomas Martyn, professor of botany at the Cambridge Botanic Garden in the 1760s.At Martyn's garden, the lack of finances was a key limitation: teaching from the garden itself.This was particularly crucial when learning taxonomy, which required the study of many different species of plants at first hand.Such limited teaching space was likely to attract fewer students and, as fees were paid directly to each lecturer rather than via the university, this in turn affected the funds available for the garden and its gardeners.Martyn tried various methods to keep his teaching going in Cambridge.One such innovation was to transform his original botanic lecture series into a general natural-history course, including animals and fossils, before abandoning lecturing altogether in 1796 due to lack of interest from students. 21s this article will explore, one of the clear roles of the head gardener, or custodian, as he was termed at Oxford, was as the provider of large quantities of botanic specimens for the classroom.This was in part a response to a fascination with taxonomic systems, such as that promoted by Linnaeus, which required close examination of the plant's sexual organs.Hope, along with Thomas Martyn, was one of the first to teach this system. 22t is clear from notes recording Hope's lectures that close examination through dissection formed a central part of his teaching method.In reference to a dissection of a tulip, he explained that 'it is necessary to be neat and cautious in your dissections & repeat them often'. 23he case studies of William Lang, a gardener at Glasgow, and of John Williamson and Andrew Fyfe at Edinburgh, allow us to interrogate how gardeners were instrumental in facilitating this pedagogical approach, through the maintenance and use of collections of vast quantities of living specimens.As Johnson has noted in her work, particularly in relation to David Moore (curator of the Glasnevin botanic gardens in mid-nineteenthcentury Dublin), such men often occupied a 'hybrid position between gardening and science'. 24These three cases further highlight the interrelationship between the gardener, the garden as a physical entity and the gardener's role as intermediary between the collection and other human actors.As well as encouraging us to see science as geographically grounded, historical geographers such as David Livingstone have highlighted how 'spaces are produced, made, constituted by human actors', which emphasizes the importance of the role of people, including technicians and labourers such as gardeners, in the creation and use of scientific spaces. 25Emma Spary has expertly explored the relationship between the network of human actors and the botanic garden with particular attention to the Jardin du roi, Paris.Through this work she has established that there was a network of many different participants of differing levels of skill, including day labourers and expert botanic gardeners, who were all needed to maintain, understand and share knowledge regarding the living collections. 26As these geographers and historians suggest, scientific knowledge creation in the botanic garden can best be viewed as cocreated between the gardeners and the spaces they shaped and inhabited.
Gardeners, then, can be seen as particularly vital actors in this period, as they created and maintained the physical space and its living specimens, as well as functioning as intermediaries between different audiences, and between humans and plants.The consideration of this interrelationship between actors, objects and methods of enquiry builds on that explored by scholars included in Klein and Spary's Materials and Expertise in Early Modern Europe: Between Market and Laboratory. 27Gardeners, in addition, offer a new way to consider the relationship between practical and scholarly work as already explored by a range of authors in work such as The Mindful Hand. 28his article examines the blurring of demarcations between the head and the hand within the botanic garden through the various roles of the gardeners as toilers of the soil, collectors of specimens, custodians of collections, demonstrators, guides, artists and experimental technicians.As they created the space in which they worked, as well as facilitating research and pedagogical activities, gardeners are particularly useful objects of study, as they challenge distinctions between skill, craft and scientific endeavour.Gardeners, therefore, provide a way to consider the connectedness between art and science as methods of knowing, methods that characterize not only botany but also anatomy.

The garden as a botanical classroom
Botanic courses in this period were generally open to anyone who paid the fee, but the main audience was medical students.In Edinburgh, botany was a compulsory subject from 1777 along with anatomy and surgery, chemistry, materia medica and pharmacy, medical theory and practice, and the clinical lectures of the Royal Infirmary. 29This is not to say that all medical students attended botanical lectures.As Lisa Rosner has identified, in Edinburgh 'it only attracted an average of 25 percent of students in each cohort'. 30his was partly because the course ran in the summer months when students wanted to be back home but it was also not the most sought-after skill.According to the Guide for Gentlemen Studying Medicine at the University of Edinburgh, as noted by Rosner, the main reason for studying botany was that 'it would keep the practitioner's abilities from "being called into question by his ignorance of the principles of a science which is vulgarly believed to be necessary"'. 31As with all student feedback, this is only one opinion and it is clear that John Hope's lectures on botany at Edinburgh were well attended.The range of students attending went well beyond those with medical interests, suggesting a shift away from medicinal botany to botanical study in its own right, as well as a growing interest in botany for agricultural and other economic purposes.
As well as highlighting the problems of funding these complex spaces, Cambridge offers an insight into this eighteenth-century transition between the earlier physic garden and the nineteenth-century scientific botanic garden.In 1725 Richard Bradley, the first professor of botany at Cambridge, declared that for real improvements to be made in British agriculture farmers required 'opportunities and judgement to try experiments' or 'some fixed place, where they might see examples of all kinds of husbandry'. 32e hoped that as well as collecting plants for medicinal use and 'choice vegetables from foreign countries', the Cambridge garden would make a little space available 'for experiments tending to the improvement of land, which may be the means of increasing the estate of every man in England'. 33The long-awaited Cambridge botanic garden was eventually created in 1760 through the benefaction of Richard Walker.However, in many ways it represented a step backwards as it mirrored the design and uses of traditional physic gardens (it was based on the Chelsea Physic Garden), with their focus on medicinal plants and associated benefits for human health.Walker stated that 'the knowledge of plants is also of the greatest Utility to Mankind, as the practice of Physic is principally founded thereon'. 34Johnson notes, the resultant garden was designed to advance the medical uses of botany and the small size of the plot meant that larger plants such as trees were for the most part excluded.However, Thomas Martyn did adopt the teaching of Linnaean principles at the same time as Hope, and the garden was laid out with these in mind.This resulted in a more rigid garden plan, designed with taxonomy and medicine in mind, but with less room for the experimental, economic and agricultural botany as advocated by Bradley and implemented by Hope.This emphasis on agriculture and economy is key to understanding the design and use of later botanic gardens.Unlike Oxford and Cambridge, where medical teaching was perhaps stagnating at this point, in Edinburgh and Glasgow the subject was flourishing.In the case of Edinburgh, botanic teaching was at the cutting edge, incorporating experimental modes of demonstration, plant physiology and Linnaean taxonomy, all the while responding also to wider concerns regarding agricultural improvement.Scotland, as Stephen Shapin has highlighted, was home to a large public audience interested in science and the '"improvement" of the Scottish nation, most importantly via the modernization of agricultural techniques and production'.Much of this activity was centred on the Edinburgh medical school. 35Both Paul Wood and Charles Withers have investigated the offering of public and private lectures on agricultural topics, which were common throughout the period, and identified this with a particularly Scottish context. 36cotland was also important as a breeding ground for gardeners.As Ron McEwan notes, Sir Joseph Banks … described Scotland as a 'nation of gardeners' … and favoured them as plant collectors because he said, 'so well does the serious mind of a Scotch education fit Scots men to the habits of industry, attention and frugality that they rarely abandon them at any time of life'. 37is, combined with relatively high literacy rates, meant that Scottish gardeners were sought after and the Scottish botanic gardens, particularly Hope's Leith Walk garden, can be seen as a training ground for future leading plant collectors, nurserymen and head gardeners. 38This is evident when tracing the biographies of those working in botanic gardens in the nineteenth century; curators at institutions such as the Belfast and Dublin botanic gardens were Scottish, and trained in Scotland. 39n Scotland there was also an added emphasis on the relationship between improvement through the study of natural knowledge and the construction of the 'polite' gentleman who was expected to understand natural phenomena. 40Developing this geographical connection further in relation to discourses of improvement, Fredrik Albritton Jonsson argues that the push for improvement in Scotland in particular was often based on a goal of national self-sufficiency. 41As Hope was one of the intellectuals interested in this movement it was perhaps not surprising that his Leith Walk botanic garden should have included space for trees, which had economic value, and for other potentially lucrative plants, such as rhubarb. 42he inclusion of larger trees and shrubs also encouraged more picturesque planting with sinuous paths that allowed larger individual specimens to grow in their natural shape, both for classification purposes (essential for the 'natural' system) and to be shown off to visitors. 43This again reflects a movement towards a new taxonomic aesthetic that included trees as well as the traditional smaller plants found in earlier physic gardens.Although Hope did not delineate an area specifically as an arboretum within the Leith garden, there were enough trees within the garden for the landscape designer John Claudius Loudon to note an area with this term on his own copy of the Leith Walk plan. 44By the mid-nineteenth century, taxonomically organized tree collections had become an important feature of the botanic landscape; the Leith Walk garden was on the cusp of this shift. 45ack in Cambridge there was far less irregularity in the design of the garden, and the resultant rigidity was also reflected in the demarcation of roles within the garden that Walker stipulated.A 'Reader on Plants', as the academic role was described, was to be 'proficient in Botany, and otherwise qualified in learning, so as to read his lectures in Latin or English'.Whereas the horticultural curator 'should always be so well skilled in the System of Botany so as to range his Plants in their proper order'. 46However, this distinction became blurred when the first curator, James Miller (son of Philip Miller the head gardener of Chelsea Physic Garden), quit after seven years, leaving Martyn to take up the role of both curator and reader.This highlights the close relationship between the applied and theoretical work of the garden; these posts could be interchangeable as well as interrelated.
This close relationship played out a different way in Oxford, where James Benwell worked for more than forty years as a gardener.His exact position is unknown but presumably he worked under the head gardener or custodian of the garden whilst Sibthorp was the professor.Despite his lack of distinction, he was remembered by the botanist and later custodian of the garden William Baxter as 'although uneducated, a very intelligent man'. 47Baxter went on to note that Benwell had an 'accurate knowledge of British Plants, and of their localities in the vicinity of Oxford, and a singular talent for observation in every branch of Natural History'. 48Benwell's practical understanding of botany rendered his services highly valuable, in Baxter's opinion.In particular, Benwell assisted Sibthorp in his herborizations (the collection of botanic specimens in the field) when he was working on his Flora Oxoniensis.Thus we have a member of the garden network whose role extended beyond the garden and who was credited with expert knowledge despite being employed in a role below that of head gardener.Indeed, on his retirement at the age of eighty-two, a portrait depicting him returning from a botanical expedition to the field, with the Danby Arch of the Oxford botanic garden in the background, was engraved to raise money to support him in his final years (Figure 2). 49'The want of a proper Gardiner '  11  We have limited biographical details of gardeners such as Miller and Benwell; they are indeed barely visible within the archives.In contrast, we have a personal record of tasks undertaken by William Lang, a botanic gardener in Glasgow, as well as the detailed notes and accounts kept by Hope regarding his practice at Edinburgh.Through these, we can see the essential nature of gardeners as skilled intermediaries operating within teaching and experimental botany.
'Because a certain number of different plants, all in flower, must be had for each lecture': William Lang and the Glasgow University gardens It is rare to find accounts written first-hand by botanic gardeners in the late Georgian period, so it is worth beginning at Glasgow with the personal experience of William Lang, who was forced to defend his reputation as a good gardener in the 1800s.Lang probably learnt his trade from his father, Robert Lang, who had been appointed to the post of college gardiner in 1784.Robert's job description was 'to take care of the Physick Garden and to keep in order the College Garden by cutting walks and rolling them, clipping the Hedges, dressing the borders etc'. 50William probably conducted similar work to his father, at least initially. 51he wages for such work were rather paltry, with Robert Lang being given 'a salary of Ten pounds a year … and … a house rent-free.The said Gardiner is also to have the grass of the College Garden for which he is to pay Ten pounds as yearly rent'. 52As Boney suggests, it would seem that profit from sales of the grass, most likely as a crop of hay, was the only real income for the gardener and his family, although this was both weatherand market-dependent.The lack of proper pay was an ongoing issue.In 1789, William Hamilton, in his role as professor of anatomy and botany, managed to argue that there was enough work in the various gardens to pay Robert seventeen pounds a year, along with the grass of the college garden (estimated at eight pounds sterling), and one pound for tools. 53The downside to this was that 'no wages will be paid to him for labourers or to other assistants employed by him unless he produce a written order from the Garden Committee for employing them'. 54Given that there was an awareness of how important a specialist gardener was to the provision of botanical teaching, as laid out in Cullen and Hamilton's earlier petition, he was obviously still viewed by much of the faculty as any other labourer.He was responsible for the various gardens on his ownalthough at least the committee considered the role to be a full-time one for the first time. 55hen William Lang took over from his father in 1801, the terms of his employment remained much the same.However, the difficulties he began to face seem to be related directly to the development of botanical teaching at Glasgow and the increasing numbers of students.Towards the end of Lang's father's tenure in 1798, student numbers had gradually decreased to a low point of eight under Professor James Jeffray's tutelage. 56The student figures recovered back to twenty-two in 1801 under Dr Thomas Brown, who was appointed by Jeffray to cover his botanical teaching.After this time the student numbers then rose steadily, reaching fifty-five by 1810. 57It was this rise in the number of students attending the course that appears to have caused cracks to emerge in Lang's ability to fulfil his role.
In 1806, Brown, as the botany lecturer, wrote to Jeffray in response to criticism regarding the management of the physic garden: I am very sorry to learn that the College is dissatisfied with William Lang's behaviour & I am much afraid that it has been improper in many respects, but I can only say that as far as the Botanical Department is concerned I have no fault to find, but every reason to be completely pleased with it.That plot of ground which is dignified with the name of Botanic Garden is so very barren, that its produce can scarcely be of any advantage to a lecturer of Botany.He is therefore, under the necessity, during the greatest part of the course, both of collecting plants himself in the fields & in neighbouring gardens, & of trusting to the exertions of the gardener. 58om this letter we can see that issues had arisen yet again regarding the state of the Glasgow botanic garden.In this case, that Lang was finding it necessary to collect plants from elsewhere to satisfy Brown's teaching needs.The garden was in fact in such a poor state that Brown in the same letter despaired, 'I have so little to shew the students, everything looks so meager, that I was even doubtful of the propriety of raising the fee'. 59The interrelationship between botanic teaching and the garden can also be seen in the rules for the Oxford professor of botany in the 1730s, which stated, 'the Length of ye Lectures to be calculated in Proportion to ye number of Plants growing in the Garden so as that ye whole Garden may be demonstrated every year'. 60Similarly, the Royal Dublin Society stated that at Glasnevin, 'Lectures on Botany at large, to be given during the season when the generality of plants are in flower, for the better demonstration of the sexual system.And the professor [is] to be allowed to use the house and gardens for delivering Applied in the Arts, Medicine, and in Domestic Economy, vol. 1, London: John Murray, 1830.Shultes states that 'at present the sons carry on the management of this large nursery, which they themselves say contains one hundred acres, and requires the labour of from one hundred and fifty to two hundred workmen' (p.74).This is obviously a commercial operation on a much larger scale but it suggests that Glasgow was woefully underresourced.Thanks to Suzanne Moss for this reference.56  'The want of a proper Gardiner ' 13 them'. 61 This direct relationship between teaching material and the course shows how intertwined the physical place and its contents were with the scientific activities, and how crucial the gardeners were as intermediaries and custodians of the living collections.
Brown supported Lang, arguing that 'William has always been active & intelligent in this part of his duty' as an assistant to the lecturer in botany. 62He went on to make an explicit distinction between common gardeners and those with specialist knowledge, by writing that Jeffray 'must be sensible that a common gardiner, ignorant of the names & places of growth of the wild plants in this country, would be entirely unqualified for the office of assistant to the Botanical Lectureship on its present foundation'. 63This status, assigned by Brown, raised Lang above a mere labourer or unskilled gardener.It is an instance of social mobility that to a lesser degree resonates with Anne Secord's artisan botanists who created botanical societies where they would share expert botanical knowledge as well as local expertise. 64Unfortunately, research for this paper has not yet found a link to any societies for any of the gardeners described, but they were likely to be members of informal as well as more formal botanical networks.
Given the financial difficulties encountered by gardeners, the development of specialist botanical knowledge could be valuable in the acquisition of better-remunerated employment.An advertisement from 1783 recommended that the candidate 'thoroughly understands his business, viz, Kitchen garden, with Forcing in all its branches, also Botanic Garden, Pleasure-garden and Nursery'. 65As Mark Laird identifies, the aim of John Claudius Loudon's Gardener's Magazine, established in 1826, was 'to "promote as well as to record social and environmental improvements", including the "conduct and conditions of gardeners"'. 66Laird also describes how gardeners were often classed as just above the level of weeder women 'but not much above the level of beasts' in country house estate accounts in terms of financial cost. 67he lack of remuneration for gardeners did not go unnoticed by Hope, and on a to-do list written by him in 1783 he placed the issue of the head gardener's wages at number one: 'wages risen, besides perquisites abridged; selling plants; showing garden; originally way too little'. 68Here he also indicated the various other roles performed by Williamson, which included the selling of plants in order to subsidize his income.Conducting these sales placed the botanic garden in a much closer relationship with the commercial nursery than is generally understood. 69Hope's list also highlights the additional role of the gardener as someone who showed people around the garden. 70As head gardeners were struggling financially, it is no surprise to find that gardeners further down the scale could be classed alongside other more menial posts.For example, in 1822 the minutes of the Glasgow faculty record the employment of 'John Walker to be Gardiner, Bellringer and Scavenger'. 71This undermines the importance of specialist horticultural expertise in fulfilling a gardening post but does highlight the blurred lines between various roles within a university setting.
In the case of Lang, with the financial burden of his mother and several younger siblings, it was perhaps unsurprising that he succumbed to the temptation of utilizing his specialist knowledge for his own benefit.In his letter to Jeffray, Brown also admitted that 'William unfortunately engaged in the business of an apothecary, but this imprudence is now over & I know he lost considerably by the speculation that he will not engage in a similar one'. 72Boney suggests that Lang may have used the college's plants for this activity, which might go some way to explaining the committee's general displeasure. 73here were clear expectations of how a good gardener should behave if we look at the example of Oxford.A list of rules and an oath were drawn up for the gardener in the 1730s, which give a sense of what the managing committee expected 'a good and skillful Gardiner to do'. 74These responsibilities fell under three main categories: This note about the custodianship and care of the plants also links the interdependence of the finances and the gardener's role.One of the clauses of the oath requires him to state that he will 'not suffer any Waste or Damage to be made of any kind whatsoever, nor sell nor permit to be sold any Roots, Plants, Flowers, Fruits, Seeds, or Specimens of Plants, nor give away nor exchange any Thing in the Garden without special Leave from the Professor'. 76This, and the need to show the professor the accounts of money taken for showing visitors around the greenhouses, suggests that the gardener was expected to behave in a fiscally responsible manner and not to profit excessively from his post. 77t is clear from Lang's story that there were similar expectations at Glasgow regarding what constituted a good gardener.The use of college plants for private profit, or allowing his care of the garden to suffer due to his duties as an apothecary, would be in direct contravention of his role as a custodian.Brown tried to counter this concern on Lang's behalf by asking the committee to take into account the paltry '"emoluments" derived from the office of college gardiner', which were not sufficient to maintain a man with his family in such a costly city. 78All this appears to have fallen on somewhat deaf ears, and on 25 January 1807 Lang himself wrote a detailed representation to the committee, reflecting Brown's argument regarding his own financial and family circumstances.
Lang's representation countered the blame placed upon him for not keeping the college garden in proper order, and demonstrates the conflict that arose between the various roles Lang was meant to perform.The following is a long quotation but, given its importance as a first-hand account from him, it seems important to include his own words at length: During the summer when the Botanical lectures are going on, the garden allotted for that Department furnishing but a very few specimens for illustrating the Science of Botany, it is required of me to collect elsewhere whatever plants may be necessary for carrying forward the lectures.For which purpose I have to traverse the country round in search of plants: and that, Gentlemen, not on a particular occasion but almost every day of the course.A great part of my time therefore which should be devoted to dressing the Gardens is occupyed in this manner.Because a certain number of different plants, all in flower, must be had for each lecture.And oftentimes after, I have travelled to a wood or waterside two or three miles from Town.I have been disappointed in finding the individual plants wantedand must again set out to some other quarter to find them.And Gentlemen, as the number of students last year was upwards of thirty, it became necessary for me to provide upwards of thirty specimens of each individual plant demonstrated.And as several hundred Genera and Species were examined last season, the Botany Garden not furnishing near one hundred in perfect condition.A great proportion of my time must be occupied in this manner. 79re we get a detailed insight into the interrelationship between Lang's role in the classroom and the limitations of the garden as a teaching resource.Through necessity the Rousseauean vision of the gentleman botanizing at leisure is transformed here into a difficult, time-consuming and potentially costly act.Sadly for Lang, neither his testimonial, nor that of Brown, appears to have been enough to convince the committee that he was a good gardener and should be retained.By the end of 1807, Brown was no longer employed by the college as a gardener and he disappears from the record thereafter.
'Esteemed for eminent skill in his profession': John Williamson and the Leith Walk garden Edinburgh, like Glasgow, already had established physic gardens when John Hope decided to develop a new botanic garden there in the 1760s. 80Having been awarded the joint chair in botany and materia medica at Edinburgh University, and appointed King's Botanist for Scotland and superintendent of the royal garden in 1761, Hope was well placed to lobby for a new, larger botanic garden, and obtained the necessary funds from the Treasury both to combine the earlier collections and to expand its botanical range. 81In this regard, he was far more successful than the Glasgow or earlier Cambridge professors, and the Leith Walk garden was established in 1763 for an ever increasing number of medical students and other interested visitors. 82s well as creating a much larger, purpose-built botanic garden, with an immense 140foot glasshouse range for exotics, the Leith Walk space included a 'botanic cottage'. 83his was used as both a lecture room for teaching botany (on the first floor) and accommodation (on the ground floor) for the head gardener and his family. 84Its location on the periphery of the garden, near the entrance gateway, physically highlights the role of the gardener as a warden or gatekeeper of the collection.The head gardener was visible in both the structure and materiality of the garden through his own cottage, which allowed him to monitor the entrance to the garden; 'the wing walls and doors at their side of the house would serve as staff and public entrances to the garden'. 85he first head gardener to live in the cottage was John Williamson.He was head gardener for twenty years from 1760, at the establishment of the Leith Walk garden, until his death in 1780.His personal role within the Leith operation can also be found as a trace in the early physical layout of the garden.Not only was the cottage marked as Mr Williamson's house on the 1777 plan, but one of the plant beds in front of the glasshouse was also labelled in Williamson's honour.Having a named bed placed Williamson in exulted botanical company.Other beds in this section of the garden were named after prominent botanists, both contemporary and historical, as well as after patrons, including the influential Lord Bute, and others who exchanged botanical specimens within Hope's extensive and powerful network.After Williamson's untimely death in 1780, Hope installed a memorial to him in the garden, which recorded that he was 'esteemed for eminent skill in his profession' (Figure 3). 86That, along with the naming of the bed, suggests that Hope respected his horticultural expertise.This type of monument set within a garden was generally only reserved for more elite figures.At Leith Walk the only other memorial which has survived is a stunning urn dedicated to Linnaeus.This memorial is a physical reminder of the interlinking network of the garden, gardener and professor.As Stephen Harris notes in relation to Oxford, the greatest periods of success for the garden were when 'relationships between horticultural and academic staff are strongest'. 87t Leith Walk, the purpose-built cottage with lecture theatre on the first floor emphasized the important role of the botanic garden as a teaching space, and the gardener's place within that sphere.As we have seen, Hope's main focus was on the teaching of botanical science rather than the medicinal uses of plants.Notes of Hope's lectures made by one of his students, Francis Buchanan, support this account of the botanical focus of his courses. 88At Edinburgh, as well as needing someone to both grow and demonstrate plants for the students, Hope also employed Williamson to conduct experiments to accompany his lectures.In the lecture notes, Hope explained that in the Leith Walk garden 'we are making experiments here, but experiments on trees and plants are very different from those on animals'. 89These experimental examples formed the core of much of his teaching and Hope referred to them throughout his lectures.This suggests that the gardener showed the actual experiments to the students or, where this was not possible, Hope specially commissioned teaching diagrams depicting the results.
Williamson kept a notebook outlining the experiments he was conducting in the garden and their results, as well as a list of experiments that were physically based in the gardener's house. 90From this, we can see that Williamson was acting as an invisible technician in common with other areas of scientific endeavour. 91The experiment notebook seems to contain two sets of handwriting, which perhaps indicates the co-production of knowledge between Hope and Williamson and again blurs the division between the head and hand.In line with Shapin's argument of the dual invisibility of technicians both in the past and to historians, it is clear that Williamson's research was appropriated by Hope without credit.According to Noltie, Williamson undertook hybridization experiments between the oriental and opium poppies but when Hope reported the experiments to the younger Linnaeus he omitted Williamson's role in the process. 92his perhaps indicates that there were limits to the role a skilled technician or gardener could play within the hierarchy of the botanic garden.
Gardeners were an integral part of the teaching process at Edinburgh in other ways that were more befitting of their social status.The fee for the botany course, which was collected by Hope, was two guineas for each of the summer sessions, rising to three guineas in 1770. 93According to Jane Corrie, 'these funds were used in part to cover 'payments to the gardeners for assistance with setting up, running and tidying up after the lectures', which establishes the important role gardeners played as facilitators for the delivery of botanical lectures. 94Further evidence of the practical roles gardeners played in Hope's classroom can be seen in his own notes.In 1778 he recorded that 'one of the gardeners should keep a register of the students examined'. 95He mentions gardeners holding up specimens of 'waking' plants for students to compare with a drawing of them 'sleeping'. 96This reflected a widespread interest in plants that moved their leaves at this time and also indicates the use of a variety of pedagogical tools, as well as the role played by drawing as a way of knowing.Much of Hope's lecture time seems to have been given over to the consideration of plant anatomy and physiology, with references to similar systems in animals and humans.For example, during one lecture a student noted his claim that 'the viscera in animals are circumscribed, but in vegetables they are diffused over the whole system, by this you see they are so much more difficult to be investigated'. 97This relationship between botanic and anatomical knowledge can further be seen in the use of objectbased learning.Hope's contemporary, the anatomist and man-midwife William Hunter, described how specimens were to be passed out around the room, one student describing to the next what was to be seen. 98This sensory approach was embedded in a longer history of knowing objects through sensory practice. 99As Sarah Easterby-Smith states, 'learning and practising botany in the eighteenth century involved collecting specimens, identifying them and conserving them (or their representations) for future reference'. 100The practice of collecting took various forms, including the gathering of living specimens in gardens, of dried examples in herbaria, and of visual or material representations.As Easterby-Smith notes, the exchange of objects in order to build these collections 'meant that botany and horticulture, like the other descriptive disciplines that comprised natural history, were notably sociable'. 101It is perhaps, then, not surprising that gardeners became collectors in their own right as collecting was both an integral part of training the senses and a means of participation within important networks.
Thomas Somerville was a later head gardener at Leith Walk (1807-1810) and his personal collection of books and specimens was sold on his death in April 1810. 102Within the sales particulars Sommerville was described as the manager of the Edinburgh botanic garden, but we know little else about him.Notes on the botanic garden compiled at the start of the twentieth century describe him only as having been in the role for three years and just twenty-seven years old when he died.The notice of his death in the Scots Magazine of 1810 described him as a 'young man of great abilities both as a professional gardener and botanist', which suggests that his abilities were widely recognized. 103The list of his collection within the sales particulars is seven pages long and includes a variety of objects such as minerals, shells, fungus, crabs, a petrified oyster, stuffed birds, a hairball from the stomach of a cow, pressing boards and a book for collecting dried specimens, and various botanical works including 'Boerhaave's Index Plantarum and Linnaeus system of Nature in 7 vols.translated by Turton'. 104One can only speculate whether this varied collection of specimens and books was used by Somerville for his own private study, to facilitate his own networking, as a financial legacy for his family or for teaching students.Nonetheless, the ownership of such a collection suggests that Somerville was involved in knowledge creation within sociable networks similar to those in which more elite gentlemen such as Hope participated.
There are suggestions that gardeners were also facilitating the creation and dissemination of knowledge within country house estates, which is a topic deserving of further study.For example, we know that at Bulstrode Park in Buckinghamshire, the gardener accompanied the avid naturalist and plant collector the Duchess of Portland and her friends and fellow conchologists on expeditions to gather freshwater snails and bivalves in the local area. 105Upon their return to the house, a lively discussion concerning the classification of shells would take place in the presence of 'visiting naturalists, and interested members of her household, including Mary Delany, the Reverend Lightfoot, the artist Ehret, and even her gardener J. Agnew'. 106hen Lightfoot wrote up his account of the discovery of new shells for Philosophical Transactions, Agnew and even the duchess (as a woman) were only mentioned in passing.Towards the end of his letter to Joseph Banks, Lightfoot recorded that Patella oblongata 'was found adhering to the leaves of the Iris pseudacorus in waters near Beaconsfield, in Buckinghamshire, by Mr Agnew, Gardener to the late Duchess Dowager of Portland; by whose sagacity wall the preceding shells were discovered, and by whose faithful pencil they were drawn'. 107Here at least Agnew receives credit for both the discovery and the scientific drawing, whereas the Duchess of Portland is only referred to as his employer.This erasure is similar to that of Hope's accounts of experiments conducted by Williamson and does suggest that the involvement of gardeners in the creation and recording of knowledge has been overlooked to date.The secondary role of some gardeners, like Agnew, as scientific illustrators will be explored below, although it deserves further analysis beyond the confines of this paper.usually held by a student, which provided free living quarters'. 115Again this reflects the precariousness of employment in this period.Highlighting his artistic prowess, Fyfe produced a couple of anatomical textbooks that included his own drawings, thereby making him a key figure producing teaching materials for both botany and anatomy in Edinburgh. 116Fyfe acted as the curator of a collection of anatomical figures given to the university by Monro Secundus in 1800, which suggests that he was also interested in the material culture of teaching as well as that of illustration.As Daniela Bleichmar observes, illustrations were crucial to naturalists in the eighteenth century as they helped to bridge the gap between 'objects "out there" in the field and the world of objects "in here" in collections'. 117The illustrations created by Fyfe were similar in their ability to link objects in life with the dead specimens of the teaching room.It is perhaps this connection between anatomical and botanical teaching that gives us another way of considering the role of technicians like Lang, Williamson and Fyfe in this period.The relationship between the visual identification needs of both anatomy and botany has already been noted by Noltie; however, there is an argument to be made that the visual is not the only connection between the two disciplines. 118arin Berkowitz's work on the anatomist and artist Charles Bell, who was a contemporary of Fyfe and Lang, provides a useful framework for considering Fyfe's role.Berkowitz analyses the pedagogical use in anatomical study of a variety of three-dimensional models, sculptures and specimens, alongside images in books, paintings and classroom drawings, and actual bodies (both dead and alive). 119She describes these media as interrelated tools that functioned together alongside texts 'to serve pedagogical and research functions, endeavours that often coalesced in a science that was rooted in the classroom'. 120Clear parallels can be drawn with the use of botanic collections as tools for teaching and the associated illustrations, models and collections (such as herbaria) that were used in conjunction with botanical specimens brought in from the garden or the field.Once viewed from inside the classroom, the gardeners, like the anatomical illustrators outlined by Berkowitz, take on a crucial role in the dissemination and production of knowledge within the botanic garden.Far more than labourers of the soil, they were part of the scientific and educational venture of the institution.
There are indications that there were also teaching resources shared between various disciplines during this period.The Glasgow faculty minutes contain a draft list of regulations for the use of the Hunterian collection (as donated by William Hunter).Within this list the minutes state that 'the Professors & Lecturers of Anatomy, Botany, Natural History, Midwifery & Materia Medica shall have access to the Corresponding Departments of the Museum, and the privilege of borrowing from it such preparations specimens and articles as may be necessary and useful in their Public Lectures & Studies'. 121Perhaps, then, we need to consider the way subjects were taught based on the material objects used, and to ask who else, apart from the professor or other lecturing staff, was involved in their creation and use.
Berkowitz also discusses the use of collections of objects in Bell's anatomy classes at the Great Windmill School in the early nineteenth century.She describes the importance of the objects as part of Bell's teaching programme and how his pedagogical approach relied on a 'cultivation of sensory perception and the training of hand and eye'. 122As we have already seen above, Hope's aim was to encourage a sensory understanding of botany, so the training of hand and eye is perhaps comparable between his own discipline and that of anatomy.The role of Fyfe as a mediator between both the botanical and anatomical classrooms is less surprising once one understands that the pedagogical techniques were closely related.This aspect of learning through drawing, the training of hand and eye, might go some way to explaining the skilled draughtsmanship of both Fyfe and Agnew, as learning through illustration was also part of botanical training. 123

Conclusion
What these cases highlight is the complex network of expertise that worked both within and beyond the immediate confines of the botanic garden.Rather than seeing gardeners as a homogeneous mass, we can instead begin to unpick their different roles and biographies and view them as occupying a range of skilled and academic positions.Head gardeners in particular could act as intermediaries between the academic head and horticultural hand, although these roles seem to be more interchangeable than they at first appear.This point is highlighted by the example of William Baxter, custodian of the Oxford Botanic Garden in the nineteenth century, who not only ran the horticultural operation but also gave the botanical lectures under the professorial terms of George Williams and Charles Daubeny. 124Here the gardener was expert enough to assume an academic role.However, as we have seen, the flow of expertise was not only in one direction.In the case of Thomas Martyn at Cambridge, the professor could also act as the head gardener when finances were limited.Rather than seeing the head and hand as separate, by close investigation of the different roles of gardeners we can instead see the interlinkages, dependencies and areas of crossover between these superficially highly demarcated posts.
It is also clear that the gardener was often in an economically precarious position and that his fortunes were tied to those of the garden itself.Academic and horticultural actors worked alongside each other most successfully where there was sufficient funding for both the physical space and the workers.Yet even in Edinburgh, which had government funding, there were clearly financial limitations: Williamson, for example, evidently needed more than one job in order to support his family, despite Hope's best efforts.The success of gardeners in achieving the status of a good or 'proper gardiner' relied, then, as much upon their relation to the financial, academic and physical resources of the botanic garden as upon their own particular skills and knowledge.Gardeners should be viewed as integral to the knowledge ecologies in which they worked.
Finally, the knowledge creation of the botanic and anatomical classroom can be seen as more closely related if we focus on their intermediaries and assistants, and consider the pedagogic approaches implemented.Art, science, sensorial education and material culture provided shared methods of both understanding and learning about the living world.Technicians, such as gardeners, were not only essential for the creation of knowledge but also acted as conduits for shared methods of understanding.
