Artist: James Gillray. Published: Hannah Humphrey. The triumphal procession (left to right) of a black woman symbolizing Quassia, a drug obtained from the Quassia tree, which is supposed to have supplanted hops in brewing. She sits astride a drayman's pole, from which is suspended horizontally a cask inscribed 'True Quassia Free from Taxation'; the pole is supported on the shoulders of two brewers, Whitbread (right), and Combe (left). She holds up in one hand a branch of the noxious tree, with a (tricolour) scroll: 'Kill-Devil [rum] for ever', and in the other a frothing tankard inscribed 'Quos-sia'. This is irradiated, the rays being inscribed 'Apoplexy', 'Palsy', 'Consumption', 'Debility', 'Colic', 'Stupor', 'Dropsy', 'Scurvy', 'Dysentery', 'Hæmorrhoids', 'Hydrophobia', 'Idiotism'. A third brewer, the very corpulent George Barclay, follows on the extreme left., waving his hat. He holds up a (tricolour) standard: 'Pro bono Publico - Quassia for Ever, - No Hops! no Malt! Down with all the Private Breweries! - Kill-Devil and Quassia for Ever!' From his apron projects a book: 'Receipts to make a Cauliflour Head'. In front of the procession is a dray-horse, with dangling chains which show that the barrel has been detached from them; its head is cut off by the right margin. On its back sits the bulky Grenville between Fox and Petty who clings to his waist. All are in court dress, and exultingly wave their cocked hats, which, like the hats of the brewers, are decorated with large tricolour favours inscribed 'Quassia for Ever'. On the horse is a pannier with a (tricolour) label: 'Grains from the Quassia Breweries for the New Piggery'; this, like the riders' pockets, is overflowing with guineas. From Petty's hat fall two bundles of papers: 'Tax upon Private Brewer[ies]' and 'Tax upon Maid-Servants'. Whitbread, who looks round at the spectator, has a favour in his hat larger than the others and having the additional inscription. 'No Private Breweries - Impeachment of Malt & Hops! No Scotch Barley', indicating his charges against Melville. On the ground lie broken hop-poles, with hop-vines still attached to them. Behind are conical stacks of hop-poles 'To be Sold for Fire-Wood'. Description from the British Museum.
