It escaped the observation of Captain Flinders.
In the direction of South 42 degrees West (magnetic) and ten miles from the west end of Percy Island Number 1, are some rocks, but I am not aware whether they are covered: they were seen by Lieutenant Jefferies in 1815.
Another patch of dry rocks was seen by me from the summit of a hill at the west end of Percy Island Number 1, whence they bore South 60 degrees West (magnetic) and were supposed to be distant about eight or nine miles.

The variation of the compass here is between 7 and 8 degrees East.
The PERCY ISLES have also been described by Captain Flinders; the bay at the west end of Number 1 is of very steep approach and not safe to anchor in, excepting during a south-east wind: the anchorage at Number 2, inside the Pine Islets, is bad, since the bottom is rocky; the ground is, however, clearer more to the southward; on the whole this anchorage is not insecure, since there is a safe passage out either on the north or south sides of the Pine Islets.

Wood may be procured with facility, and water also, unless the streams fail in the dry season.

Captain Flinders was at these islands at the latter end of September, and found it abundant.

The flood-tide comes from the north-east; at the anchorage in the channel, between the pine islets and Number 2, the flood sets to the south, and the ebb to the north; the maximum rate was one and a quarter knot.
