In returning to the ship in the evening, I steered from Horse-shoe, to the south-east end of Allen's Isle, and sounded the channel between them; but had only once so much as 3 fathoms. There was consequently no fit passage this way for the ship, and the several low islets to the north-east, precluded the expectation of finding one any where to the west of Bentinck's Island; I therefore judged it most advisable to return, and place the ship between Bentinck's and Sweers' Islands, until the necessary caulking was finished. Natives had been seen on both those islands; and this gave a hope that water might still be found to complete the holds previously to encountering the bad weather of the north-west monsoon, which I had been expecting to set in every day.
At daylight next morning the anchor was weighed; and having to work against foul winds, the breadth of the ship passage between Bentinck's Island and the southern main, was ascertained and sounded; and at dusk in the evening we anchored half a mile from the west sandy point of Sweers' Island, in 5 fathoms, small stones and shells. This anchorage between the two islands, though it may not be called a port, is yet almost equally well sheltered, and I named it _Investigator's Road_; it has the appearance of being exposed between N. N. W. and N. E. ½ N.; but the rocks from each shore occupy nearly one half of the space, and the water is too shallow in the remaining part to admit any surge to endanger a ship.
Next day, a boat was sent to fish with the seine upon Sweers' Island, and an officer went to the opposite shore to dig for water; the botanists divided themselves into two parties, to visit both islands, and the carpenters began caulking the starbord side of the ship. I repeated the observations under Inspection Hill, for the rates of the time keepers; and being informed on my return, that the midshipman of the seining boat had discovered a small hole containing a little muddy water, with a shell lying near it, I had the place dug out, through the sand and a stratum of whitish clay, to the depth of ten or eleven feet. Under the clay we found a bottom of stone and gravel, and the water then flowed in clear, and tolerably fast. This was a great acquisition; more especially as the spring was not far from the beach at the west point of Sweers' Island, where the casks could be conveniently landed, and where we had had great success in fishing.
