As the women were skinning the deer, I noticed that every few moments they would lean down and tear off, with their teeth, little round protuberances which grew on the under side of the skin. These were an inch long by a quarter of an inch thick, and were bedded in the skin, and surrounded with fat. They proved to be bots, formed by a fly that is the special torment of the deer in summer. On one skin I counted more than four hundred of them. A little child came up and offered me a handful. I found that they are considered a delicacy by the natives. The flies deposit minute eggs in the skin in mid-summer, and the larva lies under the skin, imbedded in fat. The following spring the deer is tormented with itching, and rubs against anything it can find, and so liberates the larva, which comes forth in the shape of a fly, an inch in length, only to repeat the same operation. It is a marvelous provision of nature that teaches the fly to seek the only place where its larvæ can be kept warm and safe during the terrible cold of winter. When the last deer had been skinned, the men brought axes and chopped the carcasses into equal portions, each dog receiving a good ten pounds. When I went back to the yourta I left them snarling and growling over their meal, like so many wolves. The yourtas of these natives are covered with deerhides. The hair is cut down to a quarter of an inch in length, and is put on the outside. The construction of the frame-work of the yourta is very ingenious, and is the result of centuries of experimenting. They require no guy-ropes to keep them erect, but the frame-work of poles is so constructed and so braced on the inside that they resist the most violent wind. After the poles are lashed in place by the women the deerhides are fastened over them separately, not sewed together; for this would make it difficult to move readily. At the top there is, of course, the usual exit for the smoke. The yourta that I entered was about thirty-five feet in diameter and fourteen feet high, and divided, by means of skin curtains, into eight little booths or apartments, each of which could be entirely closed, to secure privacy. These little booths are arranged around the side of the yourta, and each one is occupied by an entire family. The booths are eight feet long, five feet high, and six feet wide, and are heated only by lamps. The great fire in the center of the yourta is not primarily for heat, but for cooking purposes, all the families using it in common. The various kettles are hung over the fire by means of wooden hooks. The food is either boiled or eaten raw. They do not seem to know the use of the frying-pan. The main door of the yourta is formed by two flaps of deer skin, an inner and an outer one, which gives the effect of a storm-door. The dogs generally huddle between the two, and occasionally one of them sneaks into the yourta itself, only to be promptly kicked out.
