fathoms deep in Bering Sea and E. of the Alaska Peninsula. Salmon are to be found in almost incredible numbers. Of marine mammals, whales are hunted far to the N. in Bering Sea and the Arctic Ocean, but are much less common than formerly, as are also the walrus, the sea otter and the fur seal. All these are disappearing before commercial greed. The walrus is now found mainly far N.; the sea otter, once fairly common throughout the Aleutian district, is now rarely found even on the remoter islands; the fur seal, whose habitat is the Pribilof Islands in Bering Sea, has been considerably reduced in numbers by pelagic hunting. There are half-a-dozen species of hair seals and sea-lions. The number of fur-bearing land animals is equally large. Sables, ermine, wolverines, minks, land otters, beavers and musk-rats have always been important items in the fur trade. There are black, grizzly and polar bears, and also two exclusively Alaskan species, the Kodiak and the glacier bear. The grey wolf is common; it is the basal stock of the Alaskan sledge-dog. The red fox is widely distributed, and the white or Arctic fox is very common along the eastern coast of Bering Sea; a blue fox, once wild, is now domesticated on Kodiak and the Aleutians, and on the southern continental coast, and a black fox, very rare, occurs in south-eastern Alaska; the silver fox is very rare.
The Alaskan flora is less varied than the fauna. The forests of the coastal region eastward from Cook Inlet, and particularly in south-eastern Alaska, are of fair variety, and of great richness and value. The balsam fir and in the south the red cedar occur in scant quantities; more widely distributed, but growing only under marked local conditions, is the yellow or Alaska cedar, a very hard and durable wood of fine grain and pleasant odour. The Oregon alder is fairly common. Far the most abundant are coast and Alpine hemlocks and the tide-land or Sitka spruce. The last is not confined to this part of Alaska, but is the characteristic and universal tree. It is of primary economic importance to the natives, who use it for the most various purposes. On the islands of the Alexander Archipelago and on Prince William Sound it grows to gigantic size; even on the Koyukuk and the middle Yukon it attains in places a diameter of 2 ft. In 1902 a forest reservation comprising the largest part of the Alexander Archipelago was created by the United States government. The separation of the coast and interior floras is almost complete; only along the mountain passes and river valleys, and rarely there, is there an exchange of species. Timber, however, is fairly abundant along the entire course of the Yukon above Anvik (about 400 m. from the mouth), along the great tributaries of the Yukon, and, so far as explorations have revealed, along every stream in central Alaska; and the woods of the interior consist almost entirely of spruce. On the Yukon flats it grows in a vast forest impenetrably dense.[1] The timber line, which in the Panhandle and along the southern coast of the continental mass runs from 1800 to 2400 ft., frequently rises in the interior plateau even to 4000 ft. Next in importance after spruce, in the interior, is birch, and then balsam poplar. Thickets of alders and willows in wet places and new-made land, aspens and large cottonwoods west of the characteristic spruce area (as on Seward Peninsula), are also common. Toward the Arctic circle, the timber becomes, of course, sparse, low, gnarled and distorted. The willows in the Arctic drainage basin shrink to shrubs scarcely knee-high. Bushes are common in western Alaska, but undergrowth is very scanty in the forests. Grasses grow luxuriantly in the river bottoms and wherever the tundra moss is destroyed to give them footing. Most distinctive is the ubiquitous carpeting of mosses, varying in colours from the pure white and cream of the reindeer moss to the deep green and brown of the peat moss, all conspicuously spangled in the brief summer with bright flowers of the higher orders, heavy blossoms on stunted stalks. The thick peat moss or tundra of the undrained lowlands covers probably at least a quarter of Alaska; the reindeer moss grows both on the lowlands and the hills.[2] Sedges available for forage grow in the tundra. In August berries are fairly abundant over the interior; one of them, the salmon or cloud berry, preserved in seal oil for the winter, is an important food of the natives. The grasses are killed by the frosts in September. The western timber limit is on Kodiak Island. The Aleutian Islands (q.v.) are almost destitute of trees, but are covered with a luxuriant growth of herbage. Climatic differences cannot account for the treeless condition of the country W. of this point, and the true explanation lies probably in the fact that in winter, when the seeds of the coastal forests ripen and are released, the prevalent winds W. of Kodiak are damp and blow from the S. and S.W., while the spread of the seeds requires dry winds blowing from the N. and N.W. Such favourable conditions occur only rarely.
The Soil of Alaska seems to be in itself rich, and quite capable of agricultural development; the great impediment to this is in the briefness of the summer. Contrary, however, to the once universal belief, the experiments of the department of agriculture of the United States have definitely proved that hardy vegetables in great variety can readily be produced in the coastal region and at various stations in the Yukon valley; and presumably, therefore, all over the interior S. of the Arctic circle, save along Bering Sea; also that there is little doubt of the practicability of successfully cultivating buckwheat, barley and oats, and possibly also rye and wheat; that grasses for grazing grow generally and often in abundance; and in general that the possibilities of interior Alaska as a live-stock country are very considerable. It is calculated that a twentieth of south-eastern Alaska is available for agriculture, and that of the entire country 100,000 sq. m. are pasturable or tillable.
Industry.—The fur and fish resources of Alaska have until recently held first place in her industries. Herrings furnish oil and guano, and the young fish are packed as “sardines” at Juneau. Cod can be taken with comparatively little danger or hardship. During the Russian occupation a small amount was shipped to California and the Sandwich Islands. The take since 1879 has been practically constant. The take of halibut is increasing steadily. The salmon industry dates from 1878. The total output (in 1901, 100,000,000 ℔; in 1906, about 72,000,000 ℔), which since 1900 has been more than half the total salmon product of the United States, is more than ten' times the product of all other fish.[3] On the Karluk river, Kodiak Island, is the greatest salmon fishery in the world. More than 3,000,000 salmon have been canned here in one season. The second salmon stream is the Nushagak, flowing into Bristol Bay; this bay is the richest fishing field of Alaska, furnishing in 1901, 35% of the total production. The recklessly wasteful manner in which these fisheries are conducted, and the inadequate measures taken by the United States government for their protection, threaten the entire industry with destruction. From 1867 to 1902 the value of the total fishery product was estimated at $60,000,000. The fur-seal industry has been better protected but still unavailingly. (See Seal Fisheries and Bering Sea Arbitration.) The value of the fur seals taken from 1868 to 1902 was estimated at $35,000,000 and that of other furs at $17,000,000. The walrus, hunted for its ivory tusks, and the sea otter, rarest and most valuable of Alaskan fur animals, are near extermination; the blue fox is now bred for its pelt on the Aleutians and the southern continental coast; the skins of the black and silver fox are extremely rare, and in general the whole fur industry is discouragingly decadent. The whale fishery also has greatly fallen off; there is no profit on the oil and the whales are sought for the baleen alone; they are much less numerous too than they once were, and have to be sought farther and farther north.
Minerals.—The timber resources of Alaska are untouched
- ↑ The trees here grow as large as 10 in. in diameter and 40 or 50 ft. high; the branches do not spread, even where there is room, so that the tallest tree has a top only four or five feet broad; the roots, which cannot penetrate the shaded and frozen soil, spread over the ice or shallowly into the tundra carpeting, and often only by their matted network prevent the fall of the trees.
- ↑ 280 species of mosses proper, of which 46 were new to science, and 16 varieties of peat moss (Sphagnum) were listed by the Harriman expedition; and 74 species or varieties of ferns.
- ↑ The value of the total product of Alaska’s fish canneries was in 1905 $7,735,782, or 29.3% of the total for the United States; in 1900 it was 17.4% of the country’s total.
