Jarvis describes in graphic language the trying task of feeding the always famished, wolf-like dogs: "They are ever hungry, and when one appears with an armful of dried fish, in their eagerness to get a stray mouthful the dogs crowd around in a fighting, jumping mass, which makes it difficult to keep one's balance. After throwing a fish to each dog, it takes all of us with clubs to keep off the larger fellows and to see that the weaker ones keep and eat their share. When being fed they are like wild animals--snarl, bite, and fight continually until everything is eaten." As the dogs, worn-out by the hard journey, could not be replaced by fresh ones at the Eskimo colony of Ki-yi-lieng, Bertholf and Koltchoff waited there to bring them up later, while Jarvis and McCall pushed on, marching across the Yukon delta in temperatures below zero daily. They found the natives of this alluvial region wretchedly poor and illy protected against the bitter cold. To the eye they were a motley crowd, as they had levied tribute for clothing on the birds of the air, the beasts of the tundra, the fish of the river, and the game of the sea. There were trousers and heavy boots from the seal, inner jackets of the breasts of the wild geese, fur ornamentation of the arctic fox, and the poorer Eskimos even made boots, when seal were lacking, from the tanned skin of the Yukon salmon. With all their dire poverty they were not unmindful of their duty to strangers and always offered the shelter of the _khazeem_ (a hut built for general use by the unmarried men, from which women are rigidly excluded). His sense of fastidiousness had not yet left Jarvis, who surprised the Eskimos by tenting in the midwinter cold rather than endure the tortures of the stifling _khazeem_, which to the natives was a place of comfort and pleasure. Of this half-underground hut Jarvis says in part: "The sides are of drift-wood, filled in with brush. The roof is ingeniously made by laying logs along the sides and lashing them thereto with walrus thongs. Two logs notched on the ends to fit securely are then laid across the first logs on opposite sides, but a little farther in toward the centre. This method is repeated until a sort of arch is formed, which is filled in with earth-covered brush leaving a small hole in the centre of the roof. Other drift-wood, split in rough slabs, forms the floor, leaving an entrance space about two feet square. From this hole in the floor, which is always several feet below the level of the surrounding ground, an entrance passage has been dug out large enough for a man to crawl through it into the main earth-floored room. Over the entrance opening is hung a skin to keep out the air, while the roof opening is covered with the thin, translucent, dried intestines of the seal or walrus, which gives faint light during the day.
