ResumoRAPID silting and the consequent recent formation of a foreshore, which has quickly become covered with vegetation, has been the object of some observations made by the writer in the neighbourhood of Georgetown, British Guiana. Before describing the vegetation in any detail, however, it may be as well to give a short account of the coast as a whole and of the factors concerned in the recent making up of the foreshore on parts of it. The coast. The coast of British Guiana consists of a flat alluvial plain, laid down through the course of ages by the deposition of sea-borne clays, the greater part of which are considered to have originated in the effluent of the River Amazon, and to have been carried to their present site by the prevailing currents of the Atlantic. This plain extends inland for a distance varying from 10 to 40 miles before rising to any extent above sea-level, and is traversed by several rivers. Large areas near to the sea are below spring tide high-water level and are therefore liable to constant flooding. Narrow sand reefs here and there mark the sites of earlier shore-lines.
