the roof is first constructed and then lifted and placed upon the corner posts. [Illustration: AINU VILLAGE: OSATNAI.] In the centre of the room is the open fireplace—a rectangular space, marked out with boards set on edge. There is no chimney for the escape of smoke. The floor may be covered with mats, which are made by the women. The different members of the household have their individual places in the house. The east end of the fireplace is honorable and when a guest arrives to whom great respect is due, a box is set in this place of honor, a fine mat with decorative patterns woven into it is folded and laid upon it, and he is invited to sit down. The sleeping places along the walls are sometimes separated from each other by suspended mats. The inside wall is often hung with mats, partly as a decoration and finish and partly to cut off draughts. Over the fireplace hangs a kettle in which food is boiled; it is suspended by a wooden pothook, which has an ingenious, though simple, mode of adjustment whereby it can be lowered or raised. In the northeast corner of the house are the “treasures,” varying of course with the householder. There are great tubs for saké, cylindrical vessels with lids; they measure a foot or two in height by about a foot across, are of Japanese manufacture and are usually black lacquer with gilding. They were presented long ago to the ancestors, maybe by Japanese officials, and are prized heirlooms. There are also lacquer saké cups or bowls, of various sizes and shapes, but also Japanese gifts and heirlooms. On the wall are hung sword-sheaths with hilts in place; generally there are no blades within, whether because these have been disposed of, or because the Japanese givers thought best not to supply the enemy real weapons, we do not know. All these cups and tubs and swords make a great show, although they are all heavy with the accumulated smoke and dirt of years. Beside these treasures of Japanese origin one sees also objects of native workmanship—knife sheaths (with and without knives) and wooden quivers, some of which contain arrows, even old arrows with the famous poison on them.
