Windfall Harbor. Admiralty Island. Alaska. April 17 to May 19 1907. Frank Stephens. Windfall Harbor is a bay cut off from the west side of Seymour Canal by Windfall Island, which is about a mile and a half long. That island is com- paratively flat. We did no hunting on it except a little at the northern end. There is an Indian camp near the southern end. The main part of Admi- raltv Island lies west of Seymour Canal, but Glass Peninsula is in plain sight from camp across Seymour Canal, eastward. Several islands lie in Seymour Canal. Swan Island is about two miles northeast from our camp at the north end of Windfall Harbor. It is rather large and high. We did some hunting and trapping on it. There is very little level land on Admiralty Is- land, the mountains rising abruptly from the beach nearly all the way. About a quarter of a mile north of camp a creek comes in from the west. This has a bottom about 200 yards wide, which is covered with deciduous trees, a species of alder, but the snow was deep and we got little there. At the mouth of the creek was an extensive gravel flat that was uncovered at low tide and was resorted to by considerable numbers of gulls and some other water birds. A thick forest of spruce ("hemlock") and fir (?) mixed with a few alders along the beach, covers the lower parts of the mountains. The upper edge of the coniferous timber is very uneven, ranging from 1,000 to about 2,000 feet altitude. There appears to be more or less alder brush above the con- iferous where the timber line is low. The Boreal Zone commences at the waters edge. Deep snow covered all the region except the beach and animal life was principally restricted to the edge of the timber along the beach and the water. Scarcely any plants had come in bloom when we left and these were found only along the beach. Mammals were few in species and mostly in individuals also. Land birds were also few but water birds were abundant. I saw two or three butterflies, apparently Vanessa milberti. One pair ? of toads taken on Swan Island were all the batrachians seen. A good collection of shells was made, mostly bivalves. Univalves were poorly represented.
