Twenty miles south of Sitka, on the same island, there are a number of hot springs, strongly impregnated with iron and sulphur, the sanitary nature of which has been known to the Indians for centuries, and hither they have been in the habit of resorting for the cure of certain physical ills, especially rheumatism, to which they are so liable. Vegetation in the neighborhood of these springs is tropical. The temperature of the water is said to be 155° Fah. At the time of the Russian possession the whites built bath-houses on the spot, and much was made of this sanitarium. But all is now neglected, except that the natives still occasionally resort to the place to enjoy the tonic and recuperating effect of the waters. Anything which will promote cleanliness among the Alaskan tribes must be unquestionably of benefit to them. There are plenty of hot mineral springs all over the various island groups of the Territory, and especially that portion which makes out from the Alaska Peninsula westward towards Asia. The most fatal diseases prevailing among the aborigines after consumption are scrofulous affections; the latter is thought to be aggravated, if not induced, by their almost exclusive fish diet, supplemented by their gross uncleanliness. The Aleuts of the south, the Eskimos of the north, and the natives generally of the coast and the interior sleep and live in such dark, dirty, unventilated quarters, reeking with vile odors, that they cannot fail to poison their blood and thus induce a myriad of ills. As we have said, none of these natives seem to have any intelligent idea of medicine, and they do not possess any herbs, so far as we could learn, which are used for medicinal purposes. If a native is furnished with a prescription after the manner of the whites, he requires at least twice the amount of medicine which it is customary to give to a white man, otherwise the dose will have no apparent effect upon his system. This is a never varying experience which medical men have found repeated among all savage races.
