That evening in the camp we had an enormous bonfire of birch, juniper and rhododendrons, which made the prettiest blaze imaginable, with flames of green, blue, violet and orange. The large fire also helped to keep away the leeches. Heavy rain fell again all night, and the thermometer did not descend below 55 deg. Fahr. The morning, however, broke fine, and we started back again up the valley to Sakeding. The sun shone every now and then, giving us occasional glimpses of distant glaciers at the head of the valley. The walk through the forest, with the sunlight shining on the dark green leaves of the rhododendron and the dripping foliage, was very delightful. The undergrowth consisted of wild roses, berberis with its necklaces of scarlet berries, wild currants of a great size--sour to the taste, but excellent when stewed--wild raspberries, light feathery bamboos, birch, willow and a most luxuriant vegetation of flowers and grasses. In one or two places the mountain ash were just beginning to show traces of colour. We soon left the leeches behind us and followed our old track through the forest beside the rushing waters of the Kama-chu. Enormous rocks which had fallen from above had in places almost blocked up the river. Often on these great boulders in the middle of the stream were growing the graceful Himalayan larch. On the steepest rock faces grew vegetation of every kind, thanks to the excessive moisture of the climate, and from every tree and from every bush hung long and picturesque lichens. Crested tits and bullfinches lived in great numbers in this forest and gave it quite a homelike appearance. The climb from the river had been a steep one, and we pitched our camp at Sakeding in a downpour of rain, but towards the evening the weather cleared up, allowing us fine views of great snow peaks which showed above the mists on the opposite sides of the valley. It was too far to go from Sakeding to Kharta in one day; we therefore decided to camp before crossing the Chog La. We passed our old camp by the green lake Ruddamlamtso, and I had a long chase after some ram chakor, but they were too clever for me and ran up the hill faster than I could follow them. The large moraines which converged in this valley were specially interesting, and threw much light on its past history. Each moraine had its own long line of boulders formed of different kinds of rock, according to the character of the mountains from which they had been carried down by the ice. It was not difficult to imagine the vast glaciers by which these lines of boulders had been deposited; glaciers which must at one time have completely blocked the valley and the disappearance of which has made room for the chain of lakes which now occupy the valley. We pitched our camp at a place called Mendalongkyo--15,500 feet--in a pleasantly sheltered spot where a gurgling stream disappeared under an old moraine. In the afternoon Wollaston went out after rats, of which he secured a new variety. Our
