It is the Eastern portion of this vast territory which I have pointed out, that I have now, Gentlemen, principally to keep before your view. It goes by the general name of Tartary: in width from north to south it is said to vary from 400 to 1,100 miles, while in length from east to west it is not far short of 5,000. It is of very different elevations in different parts, and it is divided longitudinally by as many as three or four mountain-chains of great height. The valleys which lie between them necessarily confine the wandering savage to an eastward or westward course, and the slope of the land westward invites him to that direction rather than to the east. Then, at a certain point in these westward passages, as he approaches the meridian of the Sea of Aral, he finds the mountain-ranges cease, and open upon him the opportunity, as well as the temptation, to roam to the North or to the South also. Up in the East, from whence he came, in the most northerly of the lofty ranges which I have spoken of, is a great mountain, which some geographers have identified with the classical Imaus; it is called by the Saracens Caf, by the Turks Altai. Sometimes too it has the name of the Girdle of the Earth, from the huge appearance of the chain to which it belongs, sometimes of the Golden Mountain, from the gold, as well as other metals, with which its sides abound. It is said to be at an equal distance of 2,000 miles from the Caspian, the Frozen Sea, the North Pacific Ocean, and the Bay of Bengal: and, being in situation the furthest withdrawn from West and South, it is in fact the high capital or metropolis of the vast Tartar country, which it overlooks, and has sent forth, in the course of ages, innumerable populations into the illimitable and mysterious regions around it, regions protected by their inland character both from the observation and the civilizing influence of foreign nations. 2.
