V. We have only isolated and very incomplete accounts of the greater number of these migrations. Though sufficient to remove all doubt as to the fact, they tell us nothing of the circumstances which accompanied or followed them. It is quite otherwise when we come to consider New Zealand. Thanks to the songs collected by Sir George Grey, we possess the detailed history of this colonisation. This exception is doubly fortunate as giving us information upon a number of important points, and precisely in reference to those islands which, from being situated at a great distance from Polynesia, properly so called, favour autochthonic hypotheses more than all the rest of the area. It seems to me, therefore, to be advisable to enter into a few details upon the subject. It is the inhabitants of Rarotonga, one of the principal islands of Manaïa, who had the honour of discovering and colonising New Zealand. An emigration from Tonga may, however, at some unknown period have possibly joined them. The Christopher Columbus of this little world was a certain Ngahué, who was compelled to fly from his country to escape the persecutions of a queen, who wished to rob him of a jasper stone. It was doubtless chance which led him to New Zealand. He here discovered several pieces of jasper, which probably restored him to the favour of the _female chief_, for we do not hear that he was molested on his return to Rarotonga. During the absence of Ngahué a general war had broken out in his island. The vanquished party followed the advice of the traveller, who persuaded them to go and occupy the recently discovered land with him. Several chiefs joined together and constructed six canoes, the names of which are still preserved. The song translated by Sir George Grey informs us that one of them, the _Arawa_, was made of a tree which had been felled in Rarotonga, situated on the other side of Hawaïki. This was one of those _secondary Savaïs_ which I have mentioned above, and the place from which the emigrants started. “Once,” says one of those songs already quoted, “our ancestors separated; some were left at Hawaïki, and others came here in canoes.” The same song describes the accidents of the voyage, the storms which the navigators met with, the care bestowed upon the first culture of the soil, the exploring expeditions undertaken in the new country, and the disagreements which occurred between the different crews. They show that the connection with the mother country continued to exist for some time, so much so indeed that a young woman accomplished the voyage with only a few companions, and warlike expeditions started sometimes from Hawaïki and sometimes from the colony to avenge some of those outrages which were considered by these races as demanding the life of the offender.
