Although Depuch Island is one vast pile of reddish-coloured blocks, scattered about in the greatest possible confusion, sometimes resembling basaltic columns, its outline from seaward appears even. In the valleys, and on some of the more level spots near the summit, there are occasionally slight layers of soil, affording nourishment to a coarse grass, a few bushes, and several stunted eucalypti; but on the whole the vegetation of the island is extremely scanty. From the highest point we had a view over the main, extending inland for a great distance. It appeared to be flat, with the exception of some isolated rocky hills, of a formation similar to that of Depuch, from 200 to 500 feet in height, and about six miles from the shore. We could also see at a distance of twenty-eight miles a very remarkable pyramidal hill, surmounted by a tower-like piece of rock, bearing from our position South 30 degrees West. From the white appearance of many large patches of the level country, we inferred that they were covered with a salt efflorescence; and it is probable that a very great portion of it is occasionally flooded, being cut up by a number of creeks, which must overflow at spring tides, especially when they occur simultaneously with the north-west winds that prevail on this coast during the monsoon. This group of islands is so connected with the main by extensive sandbanks, that at low-water it is possible to walk across to them; and of this facility the natives no doubt avail themselves to procure turtle. It appears indeed to be only on such occasions that they can visit Forestier Group, as we saw no traces of rafts on this portion of the coast. Depuch Island would seem to be their favourite resort; and we found several of their huts still standing. They were constructed of boughs and twigs fixed in the ground, and joined overhead in a circular shape. Over this was thrown a loose matting of twisted grass. NATIVE DRAWINGS.
