4. The Mongolo-Manzhourian race amounting to 400,000. Among this race may be remarked the Mongolians properly so called, on the Selenga; the Kalmucks, a nomad people in the Government of Astrakhan, as also in Tomsk, in the country of the Don Cossacks, and partly in the Government of Stavropol. The Kalmucks appeared first on the eastern confines of Russia in the year 1630. About a century later we find them become the regular subjects of the Tsar. They seem, however, to have found the Russian yoke irksome, and resolved to return to their original home on the coasts of Lake Balkach, and at the foot of the Altai Mountains. Nearly the whole nation, amounting to almost 300,000 persons, began their march in the winter of 1770-71. The passage of this vast horde lasted for weeks, but the rear were prevented from escaping by the Kirghiz and Cossacks, who intercepted them. They were compelled to remain in Russia, where their territory was more accurately defined than had been done previously. The Kalmucks are obliged to serve with the Cossack troops, but their duties are mostly confined to looking after the cattle and horses which accompany the army. Their religion is Buddhism, and a conspicuous object in the aouls, or temporary villages which they construct, is the pagoda. Their personal appearance is by no means prepossessing--small eyes and high cheekbones, with scanty hair of a very coarse texture. In every sense of the word they are still strictly nomads; their children and tents are carried by camels, and in a few hours their temporary village, or oulous, is established. To these also belong the Bouriats, by Lake Baikal; the Toungusians from the Yenesei to the Amur; the Lamorets, by the Sea of Okhotsk; and the Olentzi, in the Government of Irkutsk. 5. Races of eastern Siberia: the Koriaks, living in the north-eastern corner of Siberia; the Youkagirs, in the territory of Yakutsk; the Kamchadales, in Kamchatka. Their number amounts to 500,000. 6. The Turko-Tartar race amount in number to 3,000,000. To their branch belong the Chouvashes, in the governments of Orenburg, Simbursk, Saratov and Samaria; the Mordvinians, in the same governments as the Chouvashes,[1] and in those of Tambov, Penza, and Nijni-Novgorod; the Tartars of the Crimea and Kazan; the Nagais, on the Kouban and Don; the Mestcheriaki, in the governments of Orenburg, Perm, Saratov, and Viatka; Koumki, in the Caucasus; Kirghizi, Yakouti, on the Lena; Troukhmentzi and Khivintzi; Karakalpaks (lit. Black Caps), Teleouti, in the government of Tomsk, Siberia. [Footnote 1: Some writers consider the Chouvashes to belong to the Finnish race.] 7. The Caucasian races inhabiting Georgia, the valleys and defiles of the Caucasian Mountains have different appellations and different origins. Among them may be noticed the Armenians, Georgians, Circassians, Abkhasians, Lesghians, Osetintzi, Chechentzi, Kistentzi, Toushi, and others. Their number is about 2,000,000.
