[270] This is the most alpine living shell in the world; my specimens being from nearly 17,000 feet elevation; it is the Lymnæa Hookeri, Reeve (“Proceedings of the Zoological Society,” No. 204).
Beyond this I recognised a hill of which I had taken bearings from Donkia pass, and a few miles further, on rounding a great spur of Kinchinjunga, I arrived in sight of Cholamoo lakes, with the Donkia mountain rearing its stupendous precipices of rock and ice on the east. My pony was knocked up, and I felt very giddy from the exertion and elevation; I had broken his bridle, and so led him on by my plaid for the last few miles to the banks of the lake; and there, with the pleasant sound of the waters rippling at my feet, I yielded for a few moments to those emotions of gratified ambition which, being unalloyed by selfish considerations for the future; become springs of happiness during the remainder of one’s life.
The landscape about Cholamoo lakes was simple in its elements, stern and solemn; and though my solitary situation rendered it doubly impressive to me, I doubt whether the world contains any scene with more sublime associations than this calm sheet of water, 17,000 feet above the sea, with the shadows of mountains 22,000 to 24,000 feet high, sleeping on its bosom.
There was much short grass about the lake, on which large antelopes, “Chiru” (Antilope Hodgsoni),[[271]] and deer, “Goa” (Procapra picticaudata, Hodgson), were feeding. There were also many slate-coloured hales with white rumps (Lepus oiostolus), with marmots and tail-less rats. The abundance of animal life was wonderful, compared with the want of it on the south side of Donkia pass, not five miles distant in a straight line! it is partly due to the profusion of carbonate of soda, of which all ruminants are fond, and partly to the dryness of the climate, which is favourable to all burrowing quadrupeds. A flock of common English teal were swimming in the lake, the temperature of which was 55°.
[271] I found the horns of this animal on the south side of the Donkia pass, but I never saw a live one except in Tibet. The Procapra is described by Mr. Hodgson, “Bengal As. Soc. Jour., 1846, p. 388,” and is introduced into the cut at [p. 139.]
The accompanying figures of the heads of the Chiru (Antilope Hodgsoni), were sketched by Lieut. Maxwell (of the Bengal Artillery), from a pair brought to Dorjiling; it is the so-called unicorn of Tibet, and of MM. HuC and Gabet’s narrative,—a name which the profile no doubt suggested.
I had come about fifteen miles from the pass, and arrived at 1 p.m., remaining half an hour. I could not form an idea as to whether Campbell had followed or not, and began to speculate on the probability of passing the night in the open air, by the warm side of my steed. Though the sun shone brightly, the wind was bitterly cold, and I arrived at the stone dykes of Yeumtso at 3 p.m., quite exhausted with fatigue and headache. I there found, to my great relief, the Tchebu Lama and Lachen Phipun: they were in some alarm at my absence, for they thought I was not aware of the extreme severity of the temperature on the north side of the snows, or of the risk of losing my way; they told me that after a long discourse with the Dingpun (or commander) of the Tibetan Sepoys, the latter had allowed all the party to pass; that the Sepoys had brought on the coolies, who were close behind, but that they themselves had seen nothing of Campbell; of whom the Lama then went in search.
The sun set behind Chomiomo at 5 p.m., and the wind at once dropped, so local are these violent atmospheric currents, which are caused by the heating of the upper extremities of these lofty valleys, and consequent rarefaction of the air. Intense terrestrial radiation immediately follows the withdrawal of the sun’s rays, and the temperature sinks rapidly.
