"The language of Caledon Bay (north-west coast) may therefore be totally different to what is spoken on the east and south coasts, and yet the inhabitants have one common origin; but I do not think that the language is absolutely and wholly different, though it certainly was no better understood by Bongarrco (a Sydney native) than by ourselves. In three instances I found a similarity. The personal pronoun of Port Jackson, 'Ngia' (I), was used here, and apparently in the same sense. When inquiry was made after the axe, the natives replied 'yehangeree-py,' making signs of beating, and py signifies to beat in the Port Jackson language. The third instance was that of the lad Woga calling to Bongarree in the boat, which after he had done several times without being answered, he became angry, and exclaimed Bongarree-gah in a vehement manner, as Bongarree himself would have done in a similar case." Captain Grey, in speaking of the Aborigines of New Holland, says (vol. ii. p. 209), "One singularity in the dialects spoken by the Aborigines in different portions of Australia is, that those of districts widely removed from one another, sometimes assimilate very closely, whilst the dialects spoken in the intermediate ones differ considerably from either of them. The same circumstances take place with regard to their rights and customs." And again, after comparing some of the dialects of South Australia and New South Wales with those of Western Australia, Captain Grey says (vol. ii. p. 216), "Having thus traced the entire coast line of the continent of Australia, it appears that a language the same in root is spoken throughout this vast extent of country, and from the general agreement in this, as well as in personal appearance, rites and ceremonies, we may fairly infer a community of origin for the Aborigines." Had we a collected and an authentic account of the dialects, weapons, habits, customs, and traditions of all the tribes of Australia with whom Europeans have already been in close or friendly contact, and which, with very few exceptions, would embrace the circuit of the whole continent, we should have a mass of valuable and interesting information, that would enable us, not only to form a probable opinion as to the community of origin of the various tribes, and the point from which they first overspread the continent, but also to guide us in conjecturing the routes which the various offsets have taken from the parent tribe, the places of contact where they have met from opposite extremities of the continent, and the gradual change which has taken place in the habits, customs, and dialects of each. In the absence of many links necessary to form a connection, we can at present only surmise conclusions, which otherwise might have been almost certainly deduced.
