Mammals from along the Alaska Highway were obtained for the University of Kansas Museum of Natural History in the summers of 1947 and 1948 by Mr. J. R. Alcorn, field representative of the Museum. He and his family visited Alberta, British Columbia, the Yukon Territory and Alaska in an automobile and trailer from June 9, 1947, to September 6, 1947, and again from June 8, 1948, to August 24, 1948. In 1947, considerable time was spent by Alcorn in Alaska; trips were made on the Steese Highway to Circle and on the Glenn Highway to Anchorage. In 1948, most of the collecting was done in British Columbia and in the Yukon Territory but a side trip was taken to Haines, Alaska.
