The Taranakis lived in deadly fear of the powerful and warlike Waikatos, and, but for the love which they felt toward their native country, would have fled, and left the conquerors to take quiet possession. They were even obliged to have their plantations in the bush, where none but the owner could find them; for they feared, and with reason, that if their dreaded enemies could discover the sources whence their provisions were obtained, they would destroy the whole plantation, and leave their victims to starve. They were in such a state of nervous alarm about a suspected invasion by their powerful neighbors, that on one occasion, when a fire was seen in the distance, every one took it for granted to be a fire lighted by the Waikatos, and in consequence every one kept awake all night, ready to give the alarm at the first unwonted sight or sound. Among the New Zealanders is a custom of retaliation which is found with but little variation in many parts of the world. If blood has been shed, the friends of the dead man issue from the pah, with the determination of killing the first person whom they may happen to meet. Should he belong to an inimical tribe, so much the better; should he belong to the same tribe, so much the worse; for in either case he is killed. On such an occasion one of the avengers would be bound to kill his own brother, should he happen to be the first man who came in the way of the party. Such an exercise of vengeance is rather an inconvenient one to those who are engaged in it; for they are forbidden the use of their ordinary comforts, they may not eat any food except that which is indigenous to New Zealand, and, above all, they are not allowed to smoke. When, therefore they have been unable to find any human being whom they can sacrifice, the aid of the priest, or tohunga, is called in. He pulls up a tuft of grass, and, after repeating one of the many incantations which abound in New Zealand lore, and of which neither the hearers nor the reciter understand one word in ten, he throws the grass into the nearest stream, in token that the avengers are released from their vow. Blood, however, must still be shed; but after this ceremony has been performed, the blood of any living thing, even though it be a bird, is held sufficient to satisfy the traditional custom of the Maori race. Elaborate rites closely allied with this ceremony are employed both before and after battle; but, as they belong rather to the subject of religion than of war, we will postpone them for the present. As the New Zealanders know that it is a point of military honor combined with personal gratification to eat the bodies of slain enemies, they are equally desirous of securing the bodies of their foes and of carrying off those who have fallen on their own side; and in many instances the anxiety to save those who have fallen has caused others to share the same fate while attempting to carry off their dead or wounded comrades.
