Arriving at Darjeeling early in 1883, he and Imboden made their way to Jongri just under Kanchenjunga on the south-west, and climbed a peak, Kang La, 20,300 feet. The Guicho La (pass), 16,000 feet, between Kanchenjunga and Pundim, was ascended, but as the end of March was much too early in the year for climbing, they returned to Darjeeling, and Imboden then went back to Europe. It was not till the end of June that Graham was joined by Emil Boss and Ulrich Kauffmann, who came out from Grindelwald. They started from Nynee Tal to attack Nanda Devi, travelling to Rini on the Dhauli river, just to the westward of Nanda Devi. From Rini they proceeded up the Rishiganga, which runs down from the glaciers on the west of Nanda Devi, but they were stopped in the valley by an impassable gorge that had been cut by a glacier descending from the Trisuli peaks. Obliged to retreat, they next attacked Dunagiri, 23,184 feet; after climbing over two peaks, 17,000 and 18,000 feet, they camped at 18,400 feet, and finally got to a point from which they could see the top of A^{22}, 21,001 feet over the top of A^{21}, 22,516 feet, and must therefore have been at least at a height of 22,700 feet. Unfortunately hail, wind, and snow drove Graham and Boss off the peak within 500 feet of the top--Kauffmann had given in some distance lower down--and it was only with difficulty that they were able to return to their camp, which was reached in the dark. The weather then obliged them to return to Rini, from which place they again started for Nanda Devi. This time they went up the north bank of the Rishiganga. After illness, the desertion of their coolies, and all the sufferings produced by cold and wet weather, they reached the glacier in four days, only to find that again they were cut off from it by a perpendicular cliff of 200 feet, down which the glacier torrent poured. Their attempt to cross the stream was also fruitless; so, baffled for the second time, they were forced to return to their camping-ground under Dunagiri at Dunassau, from which place they climbed A^{21}, 22,516 feet, by the western ridge, calling it Mount Monal. They then tried A^{22}, 21,001 feet, but were stopped by difficult rocks after reaching a point about 20,000 feet. By the middle of August Graham was back again in Sikkim and got to Jongri by September 2. With Boss and Kauffmann he explored the west side of Kabru and the glacier which comes down from Kanchenjunga. But the weather was continuously bad; they started to climb Jubonu, but were turned back. Then they crossed the Guicho La to ascend Pundim, but found it impossible; more bad weather kept them idle till the end of the month. They then managed to ascend Jubonu, 21,300 feet. A few days later they went up the glacier which lies on the south-east of Kabru, camping at 18,400 feet; and starting at 4.30 A.M. they succeeded, owing to a favourable state of the mountain, in reaching the summit, 24,015
