On we went over low-lying passes till we came to the source of the Brahmaputra, which the Tibetans call the Tsangpo. This region is not only of religious significance to Asiatic pilgrims, it is also highly interesting geographically, for it contains the sources of the Indus, the Sutlej, the Kaxnali, and the Brahmaputra. For the Tibetans, who are accustomed to give a symbolical religious sense to all designations, the names of these rivers are associated with the sacred animals - the lion, the elephant, the peacock, and the horse.
For the next fortnight, we followed the Tsangpo. Fed by numerous streams from the nearby Himalayas, this river grows larger all the time, and the bigger it gets the more tranquil is its stream. Now the weather was continually changing. Within minutes one was alternately freezing or roasting in the sunshine. Hailstorms, rain, and sunshine followed each other in quick succession - one morning we awoke to find our tent buried in snow, which in a few hours melted in the hot sunshine. Our Europeans clothes were unsuited to these continual changes of temperature, and we envied the Tibetans their practical sheepskin cloaks, belted at the waist and with long wide sleeves to take the place of gloves.
