We stayed for two days at Lapche Kang, picking flowers and enjoying the beauty of the place, in spite of the clouds which swept up from the South and filled the valley from early morning onwards. To a naturalist it was a tantalizing place; there were many unfamiliar birds that we had not seen in Tibet, but in such a sacred place I dared not offend the people by taking life, and I even had some qualms in catching butterflies. One of the prettiest sights I saw was a wall-creeper, like a big crimson-winged moth, fluttering over the temple buildings in search for insects. Having found Lapche Kang, where no European had before penetrated, and having placed it on the map, our next object was to go over the ranges Eastward to the Rongshar Valley, the head of which had been visited by members of the Expedition a few weeks earlier. This was accomplished in two long days of rather confused climbing over two passes of about 17,000 feet, crossing sundry glaciers and stumbling over moraines, and nearly always in an impenetrable fog. Our views of mountains were none at all, but the beauty of the flowers at our feet was almost compensation for that. Among many stand out two in particular, both of them primulas. One was ivory-white, about the bigness of a cowslip, with wide open bells and the most delicate primrose scent: the other carried from four to six bells, each as big as a lady's thimble, of deep azure blue and lined inside with frosted silver.[16] [16] Both of these are new species; the former has been described as _Primula Buryana_, the latter as _P. Wollastonii_. As we went down the last steep slope into the Rongshar Valley, the clouds parted for a few moments, and across the valley and incredibly high above our heads appeared the summit of Gauri-Sankar,[17] one of the most beautiful of Himalayan peaks, blazing in the afternoon sun. It was a glorious vision, but it rather added to our regret for the views of peaks that we might have seen. The next morning at daybreak the whole mountain was clear from its foot in the Rongshar River (10,000 feet) up through woods of pine and birch, to rhododendrons and rocks, and so by a knife-edged ridge of ice to its glistening summit. It recalled to me the Bietsch-horn more than any other Alpine peak, a Bietsch-horn on the giant scale and seemingly impassable to man. [17] Gauri-Sankar (23,440 ft.) was for many years confused with Mount Everest, which is still misnamed Gauri-Sankar in German maps. [Illustration: GAURI-SANKAR.]
