AMSTERDAM, New, a seaport town of British Guiana, on the right bank of the Berbice River, near the confluence of the Canje. Lat. 6. 14. 51. S. Long. 57. 31. 8. W. It was founded by the Dutch in 1796; but is now the seat of the British Colonial Government of Berbice, formerly at Georgetown. It is a healthy town; the houses, which are generally built of wood, being separated from each other by trenches which fill and empty with the tide. The whole town is intersected by canals, communicating with the sea. The harbour is good, though the passage to it is impeded at low water by a sand-bar. Three strong batteries protect the entrance of the river. Pop. about 3000.
