This is a most interesting narrative of winter journeys with dog team into many remote corners of the Yukon basin in Alaska from 1905 to 1913, connected primarily with the administration of the extensive mission work of the Episcopal church among the natives of interior Alaska. It is the work of a man of trained mind who describes clearly and entertainingly his own experiences from day to day in traveling through drifting snow, over frozen rivers and lakes and across mountain ranges, in temperatures as low as 70 degrees below zero, making camps in the open plains, on mountain sides, in log huts, and with Eskimos in their igloos, and cooking his meals for himself and his helpers, and for his dogs as well, under all the trying conditions of a subarctic climate in mid-winter. Thousands of Alaskans go through similar experiences every winter, but few have the ability to tell their experiences so clearly and faithfully as Archdeacon Stuck has done. The special value of this work, aside from its popular interest as a narrative of winter travels in the interior of a new territory about to be opened to development by the building of government railroads, is threefold: First--He calls attention very forcefully to the bad effects on the natives of contact with a class of whites whom he calls "the low down whites." He compares the good results of the mission work in settlements remote from army posts and saloons, and the discouraging results of the same kind of work in settlements where the natives are preyed upon by immoral whites with bad whiskey as their principal agency. He does not overdraw the facts. His words burn, but they are true. Second--He shows, from familiarity with the native languages, that the Indians of the upper Yukon valley, above the mouth of the Tanana, and of the entire Tanana valley, are Athabascans, speaking the same language and having the same traditions as the Indians of the Mackenzie river, while the Indians of the lower Yukon as far as Nulato, and of the upper Kuskokwim, are of a wholly different primal stock, speaking a language in no way related to that of the Athabascans. The Eskimos along the coast, in the interior, and in the lower Kuskokwim, he describes as all of one race with the Eskimos of the Arctic ocean clear to the east of Greenland. He speaks highly of the Eskimos, describing them as superior in character and in possibilities of mental development to any of the tribes of American Indians.
