It has already been mentioned, that we had not seen any westward of Clarence Strait, neither were they in use in the bottom of the Gulf of Carpentaria, nor on the south coast.* By the assistance of these and similar facts, we may hereafter be enabled to discover the exact direction in which the streams of population have flowed over the continent.

But I am not prepared to agree entirely with Mr.Eyre when he concludes, as I have stated, from the fact of the rite of circumcision having been found on the south and north-west coasts, and on the Gulf of Carpentaria, that there exists any peculiar connection between the tribes inhabiting those several points.

This enterprising traveller moreover thinks that the idea he has started goes far towards refuting the theory of an inland sea, another presumption against which he maintains to be the hot winds that blow from the interior.
(*Footnote.

An inference may be drawn from the parts of the shore on which canoes are in use, to show that the migrations of the natives, so far southwards, have been along the coast.

The raft they use is precisely the same in make and size on the whole extent of the North-west coast.) THEORY OF AN INLAND SEA.
I confess that the theory of an inland sea has long since vanished from my mind, though I base my opinion on reasons different from those of Mr.
Eyre.
