Early American Agriculture poses and for testing agricultural plants. This garden continued as a public institution up to the Revolutionary War. Although silk production was later subsidized, only rice and indigo became staple crops. Many tropical plants were found to be unsuited to the Georgia climate. (6) The famous Royal Botanic Gardens at Kew in west London, made many contributions to America through its pioneer work in plant introduction. Founded in 1760, the garden was dedi- cated to botanical study by the British royal family, and assisted in the spread of valuable plants among the British colonies. George III increased the original nine acres in 1772, and the Earl of Bute was made scientific advisor. On the death of Bute, Sir Joseph Banks became director. Banks held his post for forty-eight years, and became known as the guiding genius of Kew. He sent the first professional plant hunter, Francis Masson, to Africa in 1772. For three successive years Masson returned to Africa where he collected about a hundred new species of plants. He later explored for many years in the West Indies and South America. Plant explorer, David Nelson, took part in the explosive drama of the mutiny on the Bounty. On a previous voyage in 1771, Nelson had been a member of Captain Cook's third expedition, exploring for plants in Tasmania. The ill-fated Bounty expedi- tion was sent out to introduce the seedless breadfruit tree into the West Indies as food for slaves. Nelson died from exposure after the mutineers had captured the Bounty and set him adrift in a small boat with Captain Bligh. WORK OF JOHN ELLIS Prior to the American Revolution, the British were interested in introducing agricultural crops into the colonies. John Ellis in his first book, published in 1770,7 told how to pack seeds to prevent them from spoiling on long sea voyages. Ellis depended especially on packing the seeds in beeswax. At that time, it was thought best to procure seeds from the resident-factors in China. China was considered-as it still is-a rich source of new plants. Missionaries were mentioned as able to give information on where to secure the most valuable seeds 'Directions for Bringing Over Seeds and Plants . with a Catalogue of Such Foreign Plants as are Worthy of Being Encouraged in Our American Colonies .... Ellis' second book was titled Some Additional Observations on the Method of Preserving Seeds from Foreign Parts, for the Benefit of our American Colonies- with an Account of the Garden at St. Vincent....
