them and been attached to the Indian army in Egypt during the war. He was a most energetic, hard-working man, knew all the Tibetan manners and customs, and was up to all their tricks of procrastination and attempts at overcharging. By his knowledge and persuasive powers the Expedition was saved many thousand rupees. The Expedition when it left Darjeeling included nine Europeans. The Alpine climbers were Mr. Harold Raeburn, Dr. A. M. Kellas, Mr. G. L. Mallory and Mr. C. H. Bullock. Dr. Kellas had unfortunately in the early spring of this year tried his constitution very severely by climbing Narsing,[2] and he had also spent several nights at very low temperatures in camps over 20,000 feet, on the slopes of Kabru,[2] so that when he arrived at Darjeeling a few days before the Expedition was due to start, he was not in as fit a condition as he should have been. The two Surveyors were Major H. T. Morshead, D.S.O., and Major O. E. Wheeler, M.C. These officers had been lent by the Survey of India. Major Morshead had already a considerable experience of travelling in the Eastern borders of Tibet and in the Kham country, where he had carried out some useful survey work, and under him were three native surveyors, one of whom was left in Sikkim to revise the existing maps, which were very inaccurate, while the other two, Gujjar Singh and Lalbir Singh, accompanied the Expedition and filled in all the details of the country traversed on their plane tables at a scale of 4 miles to the inch. Major O. E. Wheeler, the other Surveyor, was a member of the Canadian Alpine Club and a very keen climber himself. He was an expert in the Canadian system of Photo Survey--a method especially useful and applicable to a difficult and mountainous country. The Indian Government had also lent the Expedition the services of Dr. A. M. Heron, of the Geological Survey of India, in order to study the geology of the country through which it was about to go, and about which nothing was known, and to investigate the problems which surround the age and the structure of the Himalayan range. Besides these, there was Mr. A. F. Wollaston, a member of the Alpine Club and a very distinguished traveller as well, who had made some most interesting journeys around Ruwenzori in Africa and in the interior of New Guinea. He accompanied the Expedition in the capacity of Doctor, Naturalist and Botanist, and was equipped with a complete collector's outfit.
