We landed almost daily upon Facing Island, which was traversed in every direction, but nowhere could we find a practicable watering place for the ship; in fact, during our excursions, it was found necessary to carry a supply of water with us, not being able to depend upon obtaining any on shore. The island is 8 1/2 miles long and 2 3/4 in greatest width; it is generally low, the most elevated part, Signal Hill, situated at its south end, measuring only 275 feet in height. Its aspect is various; the shores, as well as those of the adjacent mainland, are often muddy, and covered with mangroves, fringing creeks, and occupying swamps more or less extensive, while the remainder of the country is either covered with the usual monotonous gum-trees, or, as over a large portion of the sea face, covered with coarse sedgy grass and small bushes, on sandy ground, which rises into a series of low sandhills extending along the coast. During winter there must be much water, judging from several nearly dried up lagoons and swamps, and some empty watercourses. EXCURSION ON THE ISLAND. In company with Mr. Huxley, I made an excursion of two days' duration, with the double view of seeing the country and adding to my collection. We started heavily laden with provisions, water, arms and ammunition, besides boxes, botanical paper and boards, and other collecting gear; and although taking it very easily, the fatigue of walking in a sultry day, with the thermometer at 90 degrees in the shade, afforded a sample of what we had afterwards so often to experience during our rambles in tropical Australia. Towards the northern end of the island we found several creeks and lagoons of salt and brackish water, occasionally communicating with the sea, probably under the conjoined influences of spring tides and a strong easterly wind. Towards evening, finding among the contents of our game-bags several ducks, of two species--Anas superciliosa, the black duck of the colonists, the richest and best flavoured of all the Australian waterfowl, and A. punctata, or teal, we had them cooked bush fashion, for supper. The night being fine, we enjoyed our bivouac upon the top of a sandhill, near the sea, by the side of a dead Pandanus, which served as firewood--although it was judged expedient to keep watch by turns, and go the rounds occasionally, especially after the setting of the moon and before daybreak. We saw no recent signs of natives, however, during our absence from the ship; but former experience upon this coast had taught me how necessary it is to be ever on one's guard, even in apparently uninhabited places; and such watchfulness soon becomes habitual, and at length ceases to be irksome. Next day we returned to the ship, more than ever convinced of the comparative uselessness of the country which we had gone over for agricultural or even pastoral purposes, except on a very small scale. On our way back we met with two horses, both in good condition, which had
