The Cossacks, in virtue of their descent from the original conquerors of the country, enjoy the enviable privilege of being tax free; they are, however, obliged to render military service when required. They form the small garrison of Nishne-Kolymsk, and every year twenty-five of them repair to the fair of Ostrownoje, to keep the wild Tchuktchi in check. The Russians are chiefly the descendants of fur-hunters or of exiles; and though they have adopted the native clothing and mode of life, they are still distinguishable by their more muscular frame. The women, who are somewhat better-looking than the female Jakuts and Jukahires, are fond of music, and their traditional songs dwell on the beauties of nature--the rustling brook, the flowery mead, the nightingale’s note--all things belonging to a world of which they have no idea. The dwellings of the Russians are hardly to be distinguished from the yourts of the native tribes. They are made of drift-wood, and, as may easily be imagined, are very small and low. The interstices are carefully stopped up with moss, and the outside is covered with a thick layer of clay. An external mud wall rises to the height of the roof to keep off the wind. In a hut like this Wrangell spent many a winter month, but when the cold was very intense, he was not able to lay aside any part of his fur clothing, though sitting close to a large fire. When he wanted to write he had to keep the inkstand in hot water; and at night, when the fire was allowed to go out for a short time, his bedclothes were always covered with a thick snow-like rime.
