1926] S§warth: Birds and Mammals from the Atlin Region 53 The drawings of birds’ bills and tails illustrating parts of this report were made by Miss Anna Hamilton. The outline maps illus- trating birds’ ranges are the work of Miss Margaret W. Wythe, of the Museum staff. In September, 1913, and from June 5 to August 19, 1914, the Provincial Museum, Victoria, British Columbia, carried on field work in the Atlin region. The first trip was conducted by Mr. F. Kermode, Director, with Mr. E. M. Anderson as assistant, the second by Mr. Anderson and Mr. C. B. Garrett, and both were reported upon in annual reports of the Provincial Museum for the years 1913 and 1914, respectively. We found these published accounts of the birds and mammals that were collected extremely useful, and had occasion to refer to them constantly during our season’s work. ITINERARY AND DESCRIPTIONS OF LOCALITIES I was joined by Major Brooks at Vancouver the morning of May 17. We left Vancouver that evening, arrived at Skagway, Alaska, early in the morning of May 21, and at Carcross, Yukon Territory, the after- noon of the same day. We had planned to go on at once to Atlin, but navigation had not yet opened on the lakes, and we therefore remained at Carcross for one week. On May 27 we took advantage of an oppor- tunity to reach Atlin on a motor boat that was taking the mail, the first to be forwarded to that place for many weeks. We left Carcross at 1 p.m., reached the portage at Taku about midnight, and Atlin, across the lake, two hours later. The town of Atlin remained our base throughout the summer, the only long departure therefrom being to a camp in lower Otter Creek, where we stayed from July 26 to August 9. Major Brooks left on August 30, for a brief stay at Log Cabin, White Pass, en route home- ward. I left Atlin on September 24, reaching Berkeley on October 3. On September 7, at the invitation of Captain Moorhead, Mr. Monroe, and Mr. Taylor, I accompanied them on a trip to the police post at Nisuttlin Bay, Teslin Lake, some eighty miles (by the trail) northwest of Atlin. The first day we traversed the length of Surprise Lake and then the trail to Gladys Lake, twelve miles beyond. The second day was spent at that point (fortunately in comfortable quarters) in a downpour of rain that lasted the whole day long. The third evening we reached Grouse Creek, and the fourth afternoon
