In all probability this is the embouchure of a considerable freshwater stream, but the shallowness of the head of the bay and the usual bar off the mouth of the supposed river, determined Captain Stanley to return to the ship, as the time which would otherwise have been spent in exploring a useless creek might be devoted to some better purpose.
CROCODILES.
June 29th.
Left Fitzroy Island for an anchorage under Cape Grafton, where we remained for the three following days.

While running down to the anchorage we entered a large patch of discoloured water, with a perfectly defined margin, yet the lead showed no difference in the depth or nature of the bottom.

It would also appear that since Captain King's survey the water has been shoaling hereabouts.

On a small island inshore, the skull of a crocodile was found upon the beach, and this reminds me that several of these animals were seen in one of the rivers of Rockingham Bay.

The Australian alligator, as it is usually called, is a true crocodile, identical, according to Mr.Gray, with the common Indian species.
ISLET IN TRINITY BAY.
July 3rd.
Ran to the north-west fifteen miles, and, after having anchored midway to form a surveying station, brought up finally under a small unnamed islet in Trinity Bay.
