nor could they be convinced that, with a little caution, there was no danger to be dreaded.
The foundation of the island Rottenest is of coral, and the superstructure almost entirely sand; and there is no doubt that the lagoon is supplied from the salt water percolating through.
The island is about seven miles long, and from one to two broad. The hummocks are sand hills, many of which are entirely destitute of any kind of herbage; in the valleys are some stunted trees and shrubs, and a very little grass. It appeared astonishing to us, that Vlaming could speak in raptures of this island, which we found so miserably barren.
We had much difficulty in getting the boat launched, which the receding tide had left dry. We then beat out of the bay, and made the best of our way to Gage's Roads, through a fine opening in the reef, about four fathoms and a half deep.
Although we had been disappointed, in not finding a good passage by the way the schooner came in, yet we presumed that our little cruize had not been unattended with the acquisition of some useful knowledge, as we had discovered a good anchorage on the S.E. side of Rottenest, fit for the reception of small vessels, and altogether a place well adapted for a whaling establishment; besides, we had shown that a very practicable passage exists between it and Gage's Roads.
