Cruise of the Revenue-Steamer Corwin in Alaska and the N.W. Arctic Ocean in 1881: Botanical Notes Notes and Memoranda: Medical and Anthropological; Botanical; Ornithological.
GOLOVIN BAY.
The tundra flora on the west side of Golovin Bay is remarkably close and luxuriant, covering almost every foot of the ground, the hills as well as the valleys, while the sandy beach and a bank of coarsely stratified moraine material a few yards back from the beach were blooming like a garden with Lathyrus maritimus, Iris sibirica, Polemonium cœruleum, &c., diversified with clumps and patches of Elymus arenarius, Alnus viridis, and Abies alba.
This is one of the few points on the east side of Bering Sea where trees closely approach the shore. The white spruce occurs here in small groves or thickets of well developed erect trees 15 or 20 feet high, near the level of the sea, at a distance of about 6 or 8 miles from the mouth of the bay, and gradually become irregular and dwarfed as they approach the shore. Here a number of dead and dying specimens were observed, indicating that conditions of soil, climate, and relations to other plants were becoming more unfavorable, and causing the tree-line to recede from the coast.

KOTZEBUE SOUND.
The flora of the region about the head of Kotzebue Sound is hardly less luxuriant and rich in species than that of other points visited by the Corwin lying several degrees
