The plans of my second expedition took gradual shape during the years 1906-1907, while I was still north of the Arctic circle engaged in the work of my first expedition. It was once intended that I should be the ethnologist of the Leffingwell-Mikkelsen Arctic Expedition, sometimes known as the Anglo-American Polar Expedition, which sailed from Victoria, British Columbia, in the spring of 1906. When the proposal was made to me I found it an attractive one in everything except this: that the expedition's schooner, the Duchess of Bedford, was unprovided with auxiliary motive power, and my book knowledge of Arctic conditions made me fear that she would never reach the proposed site of operations, the west coast of Victoria Island. Mr. Leffingwell and I therefore agreed that I should not join the expedition in Victoria as did its other members, but should go overland and down the Mackenzie River to meet them at Herschel Island, which lies about eighty miles west of the Mackenzie delta. My reason was that if the expedition failed to get so far east I should be able to occupy my time profitably in the study of the scientifically unknown Mackenzie Eskimo. At that point the ice blocked her further advance until the season had become late and she was finally overtaken by winter on the north coast of Alaska at Flaxman Island.
