War.

p. 270

Before the people go to war they sing. If one of them sees blood, he will be killed in battle. When two see blood, they will be killed. They finish their singing. When they sing, two long planks are put down parallel to each other. All the warriors sing. They kneel [on the planks]. Now they go to war and fight. When people of both parties have been killed, they stop. After some time the two parties exchange presents and make peace. When a feud has not yet been settled, they marry a woman to a man of the other town and they make peace.
