Having accomplished nearly half the descent of the opposite side, we emerged from the mist, and a view of a wilder valley opened up, in which the streams were more rapid and furious, and the mountains which enclosed it more rugged and precipitous. A few trees, principally firs, were here and there scattered over the bare face of the mountain wherever they could find a sufficiently-sheltered nook. Enterprising settlers had perched themselves upon the naked shoulders of the hills, or were more snugly ensconced below by the side of the brawling stream, which was crossed here and there by primitive bridges, consisting of a log or two thrown from one heap of stones to another, with a few turfs laid upon them. I observed in the Nepaul valleys--what must be the case in every country in which the hills are composed of a soft material--deltas formed by the soil which is washed down by the mountain torrents. The mass of debris in the valley often extends quite across it, and forces the stream through a gorge, frequently of considerable grandeur in those places where the power of the torrent during the rains is very great. This circumstance adds greatly to the beauty of the scenery in the Tyrol, where the limestone formation of the hills thus worked upon spreads a soil in swelling knolls over the valley, on which the most luxuriant vineyards are picturesquely terraced. The effect, however, is very different in Nepaul, where the hills are composed chiefly of gravel and conglomerate; the deltas, consequently, produce crops of stones more frequently than of anything else. Notwithstanding the want of cultivation in the valley on which we were now looking down, it was full of a sublime beauty, the mountains at either end towering to a height of three or four thousand feet, while the path we were to follow was to be seen on the opposite side, winding over a formidable range, and always appearing to mount the steepest hills and to go down unnecessarily into innumerable valleys. It was with no little regret then that we made the almost interminable descent, apparently for the mere purpose of starting fair from the bottom of the valley, before we commenced the arduous climb in store for us over a range still higher than the one we had just traversed. We crossed the stream at the bottom by a single-arched bridge of curious mechanism and peculiar to the Himalayas, the chief advantage being the large span, which admits of an immense body of water rushing through; a necessary precaution in the case of a mountain torrent. We then toiled up the hillside by a fearfully narrow path. At times my companion seemed absolutely hanging over the precipice; and our path was not in some places above twelve inches broad; had we slipped we must inevitably have become food for the fishes in the Pomonia, which was gliding rapidly along some hundreds of feet below, and which we were informed was a good trouting stream.
