In the morning a young kangaroo was started by Mr. Cunningham but made its escape; the traces of these animals were very numerous on the sides of the hills; several birds new to us were seen, and we also found about the bushes the tail-feathers of the Cuculus phasianus (Index Orn. Sup. page 30). The summit of Crystal Head is of flat tabular form; and the sides, which are both steep and rugged, are covered with stunted trees and high grass, now quite dry: the geology of this part is principally of siliceous sandstone; and on the beach we found large detached water-worn masses of the same rock, incrusted with quartz and epidote in a crystallized state. (*Footnote. The Centropus phasianus Tem. anal. plate 24. Polophilus phasianus Shaw's Gen. Zool. volume 9 page 48 plate 11. Zool. Misc. plate 46. Pheasant Cuckow Gen. Syn. sup. 11 page 137.) No natives were seen; but, from the large fires that were burning, a numerous party was probably collected at the bottom of the port. October 11. On the 11th we got under weigh and anchored again at a few miles further up the port, near a small rocky island where the latitude was observed to be 14 degrees 32 minutes 45 seconds. In the afternoon Mr. Roe and Mr. Cunningham accompanied me in the whale-boat to examine the bottom of the port; which was found to terminate in two inlets winding under either side of a bold prominent range of steep rocky hills, thickly clothed with stunted trees. We pulled up the south-eastern arm; and having proceeded as far as prudence allowed, for from not calculating upon being absent long we had brought no provisions, we returned on board with the intention of examining it further on the following day. In rowing back, a kangaroo was seen skipping over the hills; and an alligator was lying asleep on the beach, but it rushed into the water as we passed the spot. October 12. The next day Mr. Roe, accompanied by Mr. Cunningham, explored both arms; and from his report the plan is made: but as they are merely salt-water inlets, they are of little importance. During the absence of the boat the state of our provisions and water was examined, on both of which, as we had anticipated, the rats had made considerable havoc; two of the casks were quite empty from holes gnawed by these animals to get at the water; and several were so short of their contents that we had but a fortnight's allowance left: this discovery induced me to determine on taking the first opportunity that should offer of leaving the coast and resorting to Timor; for, besides our want of water, several of the crew were attacked by scurvy, so that it was also necessary to visit it to procure some fresh provisions for them.
