The 1906 expedition may be roughly sketched, for, though it was a failure, it at least taught its leaders what routes were not possible. They started with pack-horses and a motor-boat, with the intention of trying the north-western face. They ascended the Yentna River, which enters the Susitna from the west, but found it impossible to cross the southern flanks of the Alaskan range. They then turned up the south side of the range, and reached the glacier out of which the Tokositna River flows. By this time their transport was in a precarious condition, and their horses could go no farther. They were within view of Mount McKinley, and saw not only the impossibility of the southern face, but the extraordinary difficulties of approaching even its base from that direction. They accordingly returned to the coast, where Dr. Cook left them, announcing that he intended to make one final desperate attempt on the mountain. [Illustration: Mount McKinley.] Presently Professor Parker and Mr. Belmore Browne heard, to their surprise, the rumour that Dr. Cook had succeeded. Knowing that the feat was impossible in so short a time, they disbelieved the tale, and stated their views publicly in New York. Then appeared Dr. Cook's notorious book; but before it was published he had departed for the Arctic regions. Geographical circles in America were torn with the controversy. A committee of the Explorers' Club investigated the question, but Dr. Cook refused to give evidence. Professor Parker and Mr. Belmore Browne were meantime busy with their own plans for another attempt. The 1910 expedition was again directed to the southern face. Their reasons were that for most of the journey to that face a water route was possible, and that if they failed there they believed they would be able to go on to the southern North-East ridge, which, from what they had heard and seen, they believed to be the most promising avenue of attack. They also wished to duplicate the photographs which Dr. Cook had published, and so prove or disprove his bona fides. Also, the northern side of the great mountain had been already fairly well mapped, but nothing had been done on the south side. The notion of a pack train was discarded, and all their energies were directed towards designing the right kind of boat in which to ascend the Susitna and its tributary the Chulitna till they reached the glaciers. The party consisted of eight, including a young man from Seattle, Mr. Merl La Voy, who was exceptionally fitted by Providence for the work of a pioneer. The present writer had many dealings with Mr. La Voy during the Great War, and can confidently say that he never met any one more intrepid, audacious, and resourceful.
