Mutiny on the Bounty............
The Royal Navy bought the ship for a single mission in support of an experiment: she was to travel to Tahiti; pick up breadfruit plants; and transport them to the West Indies, in the hope that they would grow well there and become a cheap source of food for slaves. The experiment, promoted through a prize offered by the Royal Society, was proposed by Sir Joseph Banks, who recommended Bligh as commander, Banks at the time being the unofficial director of Kew Gardens.
In June 1787, Bounty was refitted at Deptford. The captain's great cabin was converted to house the potted breadfruit plants, and glazed windows were fitted to the upper deck, while a lead lining was installed on the floor to catch and re-use run-off water used to feed the plants. Bligh was quartered in a small cramped cabin next to crew and officers.
