On the 10th we made sail, and proceeded a little further along the coast to Ganges Harbour, anchoring just within its eastern point. If the chart is correct, changes have taken place on the coast since the last survey. We lay opposite a small stretch of flat land, and where the plan gives the coast-line nearly straight, a little bay now exists, where stand stumps of dead trees, about which the low tides expose a broad expanse of black mud. After wading through the mud to reach the shore, we found that much of the low-lying ground was merely swamp. Part however, was covered with tall, open jungle, in which were numbers of pigeon and parrots. There were no monkeys, but tupais (_Tupaia nicobarica_) were plentiful. These appear to be entirely arboreal in habits, and are quite as active as squirrels in running along branches, or climbing about amongst smaller twigs in search of insects. Their cry is a sort of trilling squeak, which is easily confounded with the call of a bird. In crossing to the further side we found plentiful traces of Shom Pe[.n]--a faint path, a ruined hut, heaps of shells, and split seed-cases of the _Barringtonia speciosa_. The edge of the land was rapidly being eroded, and many tall casuarina trees, with roots undermined by the water, lying prostrate in the sea. At either end, this disappearing beach was hemmed in by rising ground and rocks, which at its eastern termination contained a little stream and basin of good water. On the 12th we rowed about the shores of the harbour, landing every now and then to search for the aborigines. The only signs of man's presence discovered, however, were rows of stakes set up across the creeks in the mangroves. One of these rows we utilised to hang our own net on, and obtained there such an abundant catch of small fish that we returned the greater part to the sea. The shore-line is much more indented than the outline given on the chart, and in the shallow water and mud of a little bay, rows of tree trunks still stood, two or three hundred yards from the land. This subsidence, however, is local in its occurrence, for everywhere else in the Archipelago signs of elevation are markedly present, and it is to be attributed to seismic agency--earthquakes having several times been experienced in the group--and not to a general depression of the land.
