The history of the Department of Public Gardens and Plantations, now known as the Agricultural Department, is intimately connected with the various vicissitudes through which the island has passed. The following particulars have been taken in great measure from the account in the “Handbook of Jamaica for 1900.” Directly and indirectly during the last hundred years and more the Department has been the means of introducing and propagating some of the most valuable plants, now the sources of the staple products of the island. It is a striking fact that with the exception of pimento and a few others of comparatively little value, most of the staple products of the island are derived from exotics or plants introduced from other parts of the globe, either by accident or by direct intention. The sugar-cane, though here in the time of the Spaniards, was first cultivated by the English, by Sir Thomas Modyford, in 1660; but its most valuable varieties, the Otaheite and Bourbon canes, were introduced in His Majesty’s ships by Captain Bligh as late as 1796. Coffee was introduced by Governor Sir Nicholas Lawes in 1718. The mango, brought by Captain Marshall of Rodney’s squadron in 1782, was first planted in Hinton East’s botanic garden, in Liguanea, and is now one of the commonest trees in the island. The plentiful and free-growing logwood was introduced from Honduras by Dr. Barham, the author of “Hortus Americanus,” in 1715. The beautiful akee was obtained by Dr. Thomas Clarke, first Island Botanist, from a West African slave ship in 1778. The cinnamon came with the mango in Captain Marshall’s ship in 1782, and was distributed from the Bath Garden by Dr. Dancer. The ubiquitous but graceful bamboo is also an exotic and owes its introduction to M. Wallen, who brought it from Hispaniola and first planted it in the parish of St. Thomas-in-the-East. To Wallen, formerly owner of Cold Spring and Wallenford, the friend of Swartz and a successful botanist, we are no doubt indebted for the first plants of the watercress, chickweed, wild pansy, groundsel, dead nettles, dandelion, common honeysuckle, black-berried elder, evening primrose, nasturtium, common myrtle, the English oak, white clover, and the sweet violet, now common on the Port Royal and Blue Mountains, being possibly escapes from his garden at Cold Spring, which even in 1793 was well stocked with choice selections of introduced flowers and European trees and shrubs. For the cherimoyer we are indebted to Hinton East, who introduced if from South America in 1786; to East and his magnificent garden we also owe the jasmines and many species of lilies, many convolvuli, the oleander, the horse-radish tree, numerous roses, the trumpet-flower, monkey-bread, the camellia, _Calla æthiopica_, the weeping willow, the mulberry tree, the _Arbor vitæ_, and the sweet-scented mimosa. Dr. Clarke, on his arrival as Island Botanist in 1777, brought with him the jujube tree, and the
