The songs, for which we are indebted to Sir George Grey, show that in New Zealand the greater number of the first emigrants met with no traces of a previous population. One only, named Manaïa, found upon a promontory aborigines of the country. This exception, from the very reason that it is unique, proves that this population could not have been very numerous. It has slightly altered the type of the lowest grades of the Maories, to which it has been confined. The portrait published by Hamilton Smith, and one of the skulls in the possession of the Museum, inform us that these supposed aborigines were Papuans. It is evident that they had reached New Zealand in consequence of some mischance similar to those I have just mentioned, and had not even had time to multiply sufficiently to occupy the entire shores of the North Island. The traditions of the Sandwich Islands furnish us with a fact of the same nature. They tell us that the first colonists coming from Tahiti found in these islands _gods_ and _spirits_, who inhabited the caves and with whom they entered into alliance. It is evident that we have here a troglodyte people, whose importance the legend has been pleased to exaggerate, and whose origin it is not difficult to find. If Kadou, whose history has been preserved by Kotzebue, instead of leaving the Caroline Islands for the Radak Islands, had started from the latter, and if he had made almost the same passage in the same direction, he would have landed in the Sandwich Islands. The mixture of Polynesian and Micronesian races at once explains the darkness of colour and want of purity in the features of the Hawaïans. Perhaps the same cause may account for the difference in features, manners, and industry which is presented by some tribes of the Low Archipelago. Apart from these few and, as we see, very feeble exceptions, all the islands of Polynesia appear to have been uninhabited when the navigators from Boeroe or their descendants landed. This fact is distinctly proved by traditions in Kingsmill, Rarotonga, Mangarewa, the Toubouaï Islands, etc. Purity of race testifies that this was also the case with the Tonga, Samoa, and Marquesas Islands.
