The country is likewise said to contain numerous springs of hot water. The only one that I had an opportunity of seeing was at Natchikin _ostrog_, and hath been already described. Krascheninicoff makes mention of several others, and also of two very extraordinary pits or wells, at the bottom of which the water is seen to boil as in a caldron, with prodigious force and impetuosity; at the same time a dreadful noise issues out of them, and so thick a vapour, that a man cannot be seen through it. Of the trees which fell under our notice, the principal are the birch, the poplar, the alder (with the bark of which they stain their leather), many species of the willow, but all small; and two sorts of dwarfish pines or cedars.[27] One of these grows upon the coast, creeping along the ground, and seldom exceeds two feet in height. It was of this sort we made our essence for beer, and found it excellent for the purpose. The other grows on the mountains, to a greater height, and bears a small nut or apple. We were told by the old _Toion_ at Saint Peter and Saint Paul, that Beering, during the time he lay in that harbour, first taught them the use of the decoction of these pines, and that it had proved a most excellent remedy for the scurvy; but, whether from the great scarcity of sugar, or from what other cause we could not learn, we were sorry to find that it was no longer in use amongst them. The birch was by far the most common tree we saw, and of this we remarked three sorts. Two of them fit for timber, and differing only in the texture and colour of the bark; the third of a dwarfish kind. This tree is applied to a great variety of uses by the inhabitants. The liquor, which, on tapping, it yields in great abundance, they drink without mixture, or any preparation, as we had frequent opportunities of observing, upon our journey to Bolcheretsk, and found it ourselves pleasant and refreshing, but somewhat purgative. The bark they convert into vessels, for almost all their domestic and kitchen purposes; and it is of the wood of this tree the sledges and canoes are also made.[28] The birch, and every other kind of tree in the neighbourhood of the bay, were small and stunted; and they are obliged to go many miles up into the country for wood of a proper size to work into canoes, for the principal timbers of their _balagans_, and the like uses. Besides the trees above-mentioned, Krascheninicoff relates, that the larch grows on the banks of the river Kamtschatka, and of those that fall into it, but no where else, and that there are firs in the neighbourhood of the river Berezowa; that there is likewise the service-tree (_padus foliis annuis_); and two species of the white-thorn, one bearing a red, the other a black berry.
