In 1751 Hill joined the London Advertiser and Literary Gazette as the highest paid journalist of his time. He wrote a daily letter, The Inspector, through which he gained celebrity and stoked controversy amongst his scientific peers particularly those eminent Fellows of the Royal Society some of whom he designated as little more than ‘butterfly hunters’, ‘cockle shell merchants’ and ‘medal scrapers’. Not surprisingly his candid critiques failed to gain him fellowship of the Royal Society and he resorted to a further campaign of criticism bringing him greater conflict but certainly elevating the general interest in botany as no Fellow had done. Regardless, Hill lost his lucrative writing post and then turned his hand at being a herbalist. Preparing remedies and writing on medicinal benefits, he was soon earning vast sums of money and again enjoying his notoriously extravagant lifestyle much to the irritation of his detractors.
From August 1756 to October 1757 Hill began issuing a weekly series on practical and ornamental plants for the kitchen and garden, Eden or a Compleat Body of Gardening, intended as a companion piece to his A Compleat Body of Husbandry. Both of these works were issued under the pseudonym of Thomas Hale and received good reviews from a number of unsuspecting Fellows undoubtedly to Hill’s delight. With contributions from himself and various artists, each plate usually consisted of six plants organised by season with a later edition including twenty plates of individual plants. Although critical of the works of Carl Linnaeus it is here that he begins the introduction to England of the science of identifying, naming and classifying organisms. As with most of his works its was immensely successful.
At the end of the 1750’s Hill came under the patronage of the Earl of Bute who encouraged him in the production of his monumental The Vegetable System. Disastrously, after its launch in 1761, Bute was unexpectedly appointed prime minister, causing him to lose interest and cease funding. Hill felt honour bound to persist with the project as advertised; he completed 26 folios with some 1600 plates but died in 1775 exhausted and impoverished.
