One of the side-boats conveyed to land the officers entrusted with the astronomical operations, as also the naturalists. Only with the utmost difficulty was it possible to make way through the surf, and get under the lee of a reef, whence it was requisite to make a spring to get ashore. At the spot at which we landed (named by us Morrock's Cove, and according to observation in 8° 32' 30'' N. and 93° 34' 10'' E.) the island was almost exclusively clothed with trees and brushwood. Only close to the shore did any cocoa-nut palms present themselves to the view. Although quite uninhabited at the period of our visit, it was evident, by the traces of abandoned fire-places, split cocoa-nuts, and so forth, that human beings occasionally make this island their abode, albeit the assertion repeated by several writers, that Tillangschong is the Siberia of Nicobar criminals, can only be set down to travellers' tales, or some utter misapprehension of the meaning of the natives. It would seem that the residents in Chowra and Bampoka come to this island from time to time, for the purpose of collecting cocoa-nuts, and the fruit of the _pandanus_. By dint of strenuous exertion we made our way along river-courses, which during the rainy season must rush down as most violent torrents, through a thick plantation of screw-pines, into the forest proper, which was overgrown with the most majestic representatives of tropical vegetation. To the botanist presented itself a great variety of interesting plants and timber; to the lovers of sport numerous descriptions of birds, and more especially pigeons, in such quantities that the various messes on board ship were amply provided with them. Sundown saw us returned on board, when the anchor was once more weighed. During the night we got so close in with the north side of the island that, on the following morning, a boat well-manned and carefully equipped was detached with one of the officers, who was instructed to round the northernmost promontory, in order to examine the northern and eastern sides of the island, and rejoin us on its southern shore. One of the zoologists, conceiving this minor expedition would furnish him with an excellent opportunity for examining some of the lower orders of marine life, attached himself to it. The frigate now put about, and coasted down the west side southwards. Seen from a distance the vegetation seemed quite of a European character. The eminences varied in elevation from 250 to 300 feet. Judging from the direction of the foliage on the trees, the S.W. monsoon seems to commit great ravages. Everywhere along the coast, but more especially on the south side, serpentine cropped out--giving little promise of fertility. At many spots the cocoa-palms disappeared entirely; a circumstance which must ever interfere materially with the settlement of this island by a people to whom the most profuse natural treasures are worthless and unknown, beyond wealth in cocoa-nuts.
