“On the night of the sixteenth of July, we slept at Bheemkeudar, near the source of the Coonoo and Bheem streams. There is no wood near this place, even in the very bottom of the valley, and we had left even the stunted birch at a considerable distance below; but there was a profusion of flowers, ferns, thistles, &c., and luxuriant pasturage. Captain Webb’s limit of wood is at least as high as twelve thousand to twelve thousand, three hundred feet. I would, therefore, presume the site of Bheemkeudar to be considerably above that level; say thirteen thousand to thirteen thousand, three hundred feet, above the level of Calcutta. From thence we ascended at first rather gradually, and then very rapidly, till we left all luxuriant vegetation, and entered the region of stripped and scattered and partially melting snow. From calculating the distance passed, and adverting to the elevation we had attained, I would presume that this was at least fifteen hundred feet above Bheemkeudar, or from fourteen thousand, five hundred, to fifteen thousand feet above Calcutta. “We proceeded onward, ascending very rapidly, while vegetation decreased gradually to a mere green moss, with here and there a few snow-flowers starting through it; snow fast increasing, till at length we entered on what I presume was the perennial and unmelting snow, entirely beyond the line of vegetation, where the rock was bare even of lichens: and in this we ascended, as I think, about eight hundred feet; for, though Bamsooroo Ghat may not be so far above this line, we continued ascending, even after crossing that point, and I would incline to estimate this utmost extent of ascent at two thousand feet more, or nearly seventeen thousand feet above the level of Calcutta. “Whilst proposing to consider the point of sixteen thousand to sixteen thousand, five hundred feet, as that of inferior congelation, I must observe that there was no feeling of _frost_ in the air, and the snow was moist, though hard, chiefly through the influence of a thick mist, which, in fact, amounted to a very small drizzling rain, which fell around: all which would seem to indicate, that the true line of congelation had not there been attained; but we were surrounded by snow which evidently never melted. To a great depth below it extended all over the hills, very little broken, while on the valleys from whence the Coonoo and Bheem streams issue, at full two thousand feet below, it lay covering them and the surrounding mountains in an unbroken mass, many hundred feet thick. Thus, though it may seem contradictory, the line of perpetual congelation, in fact seems fixable at even below the point I have ventured to indicate, and, I presume, might, on these grounds, be placed somewhere between fifteen and sixteen thousand feet above the level of Calcutta.
