“ We pulled down to, and landed on this island at sunset. It proved to be very similar in character to Egg Island, being a calcareous sandstone rock of recent marine formation, covered with a large deposit of guano of an elliptical form, about 76 yards long, and 64 wide, and the greatest depth at the crown 11 feet; so that, assuming the moan depth at 6 feet, we have about 9,728 yards. This island, which, for present distinction, we shall call Saturday Island, is surrounded by a shoal, connecting it with the mainland on the western side, distant about half a mile. ”

“ The prevailing rock in this vicinity is a calcareous sandstone of marine formation, which disintegrates rapidly when exposed to the atmosphere, and becomes much honeycombed when exposed to the action of the surf. ”

“ On the following morning we re-opened one of two or three holes we observed just above high watermark, apparently sunk long since for water ; at the depth of 6 feet we came to water slightly brackish, and attributing the saline quality to the proximity of the sea, we sunk another well under a limestone cliff, about 100 yards more inland; here, at the depth of 9 feet we were stopped by the rock, although there was every probability of our reaching fresh water at the depth of 10 or 12 feet since the soil thrown out was wet where we left off. ”

“ No surface fresh water was found although Mr Austin is of opinion there would be very little difficulty in obtaining it by digging on the sand patches on the rock of land marked in the chart at Tetrodon Island. Specimens of the plants and rocks were brought on board, and some of the former appear to be of new and unknown species, but that Mr Drummond will perhaps be good enough to decide. Sent off to Egg Island for the whale-boat and set our own carpenter to work to finish her. ”
