In early July 1.939, the senior writer, together with Dr. Elmer W. Brandes, of the United Stales Department of Agriculture, and Bill Brandes, his young son, spent several weeks on a camping trip in the Maine wilderness. Through the courtesy of Caleb W. Scribner, warden supervisor of Patten, Maine, we finally located ourselves about 26 miles west of Patten, in a small cabin at the southernmost end of Lake Matagamon. This area is located in Township 6, ranges 8 and 9, and falls in two counties, Piscataquis and Penobscot. We remained in this locality from July 8 to July 28, a period of 20 days.
