抄録

The sable (Mustella zibellina L.) is an inhabitant of the forests in the northern part of the Eurasian Continent and the adjacent islands. Its fur is of the highest quality, and, the best prize of the dwellers in the boreal regions of the Continent. Especially the activities of the Slavs aimed at gaining the sable caused a great commotion in the communities of the Northern Asia together with the changes in the outlooks of the forests, also affecting the political geography of the Far East.<br>The population density of the sables in Siberia under the forty-year program of the conservation of natural resources by the Soviet Union is as shown in Fig. The ecology of the sables is closely connected with the kinds of trees in, and the vegetation phase of, the taiga, the place of production for the natives who are the hunters and the gatherers of herbs. The taiga is the feeding and the breeding place of squirrels and ptarmigans which are the staple food of the sables. This is a part of the food chain of the sables, and the degree of the thickness of the forest which offers them hiding places makes another condition for their distribution.<br>The number of the sables has been on the decrease, throughout the age of Imperial Russia when they were hunted recklessly, until they are protected in the recent 30 years of conservation by the Soviet Union. The decrease was especially conspicuous in the period of the immigration of the Russian farmers into the forest-steppe of Siberia. The incineration of the forests for the purpose of grazing and hunting destroyed the taiga. In addition to this, the rampancy of the Russian usurers among the aborigines caused the devastation of the natural resources and the communities of the taiga. The population of the natives accordingly has lessened for a century or more. And the advance of the Russian adventurers who sought after the sables into the Far East has also caused great confusion to the peoples and the nations in this area.
