any kind within thirty days, a system by which the party who is in all probability guilty does, curiously enough, generally lose. A curious instance came to my notice. The oath was taken in Ungma on the spot specially associated with the deity of the wind. When the ceremony began a gale blew up, so suddenly as to attract my attention in my garden three miles away. Out of a village of six hundred houses thatch was only blown from the roof of the houses of two men, and those were the two principals on one side in the case. The blowing of thatch from a man’s roof if he has taken an oath is looked upon by Aos as a sure sign of false swearing. This story is true and other equally remarkable instances are known to the writer. Friendships. Formal friendships are of great importance. Two men become friends (okam) by exchanging gifts, consisting of half a pig, and a spear or dao or some such present, a piece of iron invariably forming part of the gift. It is usual for the sons of “friends” to become friends in turn. A man will often possess friends of this kind belonging to different villages, and frequently to a different tribe. When travelling a man will stay in his okam’s house in each village he reaches. He in turn will entertain any of his okams who come to his village. A man may not kill his okam even if he belongs to a hostile village. Should he happen to kill him in battle with a spear thrown at a venture he will not take his head. Even if no gifts be exchanged, two men of the same name regard one another as okams. I have known a man go out of his way to entertain a stranger whom he had never met before because he bore the same name as his dead son. War and Head-hunting.
