At the request of his excellency, lieutenant Dawes of the marines, accompanied by lieutenant Johnston and Mr.Lowes, about this time undertook the attempt to cross the Nepean river, and to penetrate to Carmarthen mountains.

Having discovered a ford in the river, they passed it, and proceeded in a westerly direction.

But they found the country so rugged, and the difficulty of walking so excessive, that in three days they were able to penetrate only fifteen miles, and were therefore obliged to relinquish their object.

This party, at the time they turned back, were farther inland than any other persons ever were before or since, being fifty-four miles in a direct line from the sea coast when on the summit of mount Twiss, a hill so named by them, and which bounded their peregrination.
Intercourse with the natives, for the purpose of knowing whether or not the country possessed any resources, by which life might be prolonged*, as well as on other accounts, becoming every day more desirable, the governor resolved to make prisoners of two more of them.
[*One of the convicts, a negro, had twice eloped, with an intention of establishing himself in the society of the natives, with a wish to adopt their customs and to live with them: but he was always repulsed by them; and compelled to return to us from hunger and wretchedness.] Boats properly provided, under the command of lieutenant Bradley of the 'Sirius', were accordingly dispatched on this service; and completely succeeded in trepanning and carrying off, without opposition, two fine young men, who were safely landed among us at Sydney.
Nanbaree and Abaroo welcomed them on shore; calling them immediately by their names, Baneelon (Bennelong), and Colbee.

But they seemed little disposed to receive the congratulations, or repose confidence in the assurances of their friends.
