Mole Harbor. Admiralty Island, Alaska. May 19 to June 10 1907. MAMMALS. Whales frequent Seymour Canal near the mouth of Mole Harbor. and their spouting could sometimes be seen from camp. Probably the species were the Oregon Finback and the Sharp-headed Finback. Bay Porpoise. Phocaena communis. Porpoises came in the bay frequently, sometimes rising near the beach in front of camp. Two hunters shot a porpoise near the reef at the mouth of the bay that appeared to be a Phocaena, but was not a communis. It had a large patch of creamy white on the sides and abdomen from the middle of the body to near the tail. Sitka Deer. Odocolleus columbianus sitkensis. Tracks seen frequently and Dixon killed one and Hasselborg three. Pacific Beaver. Castor canadensis pacificus. Formerly quite a colony lived at the beaver meadows four miles southwest of the bay, but the Indians trapped them all out two years ago. Beavers are common at the lakes west of the bay and in small streams in their vicinity. Saw many dams and several houses. Sitka Mouse. Peromyscus (sitkensis?). Common. We caught one alive in the wire cage and kept it several days. It climbed around on the wires as dextrously as a squirrel, using all the feet as if they were hands. These mice eat various green plants. Sitka Meadow Mouse. Microtus sitkensis. Rather common in the grass patches on the beaches and at the lakes. Swim freely whenever necessary and dive well. Admiralty Island Bear. Ursus eulophus. No tracks seen along the beach but tracks were seen in a number of places two or three miles inland. Two bears were killed and others seen on the mountains at the head of Hasselborg Lake. All tracks seen were of small or medium sized animals. Harbor Seal. Phoca richardi. Saw individuals in the bay several times. Baréátor Minkew Lutreola vison eneguemnos. None caught. Tracks seen in places
