The country on the north side of these lofty peaks, so far as I can learn, more resembles Europe. It is exceedingly high and bare, and is far from being mountainous. The rains, however, are not periodical, and the greatest falls happen in summer, so that, although several Indian rivers come from thence, they do not swell much by the melting of snow in the heats of spring. The ridge of snowy alps, although it would appear to wind very much, has few interruptions, and, in most places, is said to be totally insuperable. Several rivers that arise in Thibet pass through among its peaks, but amidst such tremendous precipices, and by such narrow gaps, that these openings are in general totally impracticable. By far the widest is on the Arun, the chief branch of the Kosi, where Maingmo on the west, and Mirgu on the east, leave a very wide opening occupied by mountains of a moderate height, and which admit of cultivation. Even there, however, the Arun is so hid among precipices, that it is approachable in only a few places, where there are passes of the utmost difficulty. Again, behind this opening in the snowy ridge, at a considerable distance farther north, is another range of hills, not so high and broken as the immense peaks of Emodus, but still so elevated as to be totally impassable in winter, owing to the depth of snow; for the road is said to be tolerable, that is, it will admit of cattle carrying loads. Somewhat similar seems in general to be the nature of the other few passages through these alpine regions. It is about these passages chiefly, and especially beyond Maingmo and Mirgu, that there is the greatest extent of the alpine pastures, which I have already mentioned; but in every part, bordering on the perpetual snow, these occur more or less. Colonel Kirkpatrick {90} thinks, that there are two distinct ranges of Emodus or Himaleh; the lower of which, separating Nepal from Thibet, is only streaked with snow, while the highest separates Kuchar, or the lower Bhotan, from Thibet. He also thought, that, from the summit of the Lama Dangra hills above Chisapani, he saw the highest ridge. Now, in the maps which I obtained from the natives, three ridges may in some measure be traced, as proceeding from about the lake Manasarawar, which may be considered as the centre of Emodus. The summits of even the most southern of these ridges, which is probably the lowest, are not covered with mere patches of snow, as Colonel Kirkpatrick seems to have thought, but on them the snow is perennial to a very great extent.
