_Physical appearance._--The Koræki are taller, and with eyes less sunken, and noses less depressed than the Kamskadales; differential points which are still more marked in the Tshuktshi. The southern Koriaks have probably encroached upon the Kamskadales, and been encroached upon by the Lamut Tungusians. The Tshuktshi have, in like manner, receded in one quarter and encroached in another. Before the Russians they have retreated towards the east and north. The Yukahiri tribes, however, they have displaced and, in some cases, exterminated. They still hold their independence. This, in some measure, accounts for our imperfect knowledge of them, little being ascertained except their uncivilized, nomadic character, their political independence, the Shamanistic nature of their religion, and their general resemblance in respect to physical conformation to the _American_ Indians. Polygamy is general amongst them, and according to Von Matiushkin, the chief authority upon the subject, the women, although certainly slaves, are allowed more influence, and are subjected to less labour than is the case amongst most other rude tribes. Deformed children are destroyed, and so are those which, for other reasons, are likely to become difficult to rear. So also are such aged and infirm persons, as have become unfit for wear and tear of a nomadic life within the Arctic circle. So great is the influence of the Shamans, or so low is the value set upon human life, that in 1814, after a terrible storm, followed by a fatal epidemic, and by a murrain among the cattle, the result of a general consultation having been, that one of the most respected of the chiefs, named Kotshen, must be sacrificed, to appease the irritated spirits, the sacrifice took place accordingly. In the first instance, indeed, the commands of the Shamans were rejected. The plague, however, continued, when Kotshen at last declared his willingness to submit. No one, however, could be found to be his executioner; until his own son plunged a knife in his heart, and gave his body to the Shamans. The Tshuktshi habitations consist of an outer and larger tent, under which are two or three smaller ones; these last being made of skins stretched over laths, and so low, that the persons inside can only sit upon the ground. It has no opening for air or light, and is entered by an aperture barely large enough for the body of the owner. An earthen vessel filled with train oil, and with a wick of moss, serves as a lamp rather as a fire; and so close is the atmosphere, that the heat which it affords is sufficient. Here the family sit, during the intense cold of an Arctic winter, either wholly naked, or with the very scantiest clothing. They call themselves _Tshekto_=_people_. "They are distinguished from the other Asiatic races, by their stature and physiognomy, which appears to me to _resemble that of the Americans_,[101] but the language is different." THE KAMSKADALES.
