Siberia, especially the river territory of the Yenisej and the Lena, possesses rich coal seams, which probably extend under considerable portions of the Siberian plain, but are yet unworked and have attracted little attention. The river steamers accordingly are fired, not with coal, but with wood, of which, if I remember right, 180 fathoms went to the voyage of the steamer _Alexander_ up the river. As the vessel could carry only a small portion of this quantity of wood at one time, frequent halts were necessary, not only for trading with the natives, but also for taking fuel on board. In addition to this, the weak engine, _although the safety valves were overloaded when necessary with lead weights_, was sometimes unable to make head with all the vessels in tow against a current which at some places was very rapid, and often, in the attempt to find still water near the river bank, the steamer ran aground, notwithstanding the continual "ladno" cry of the poling pilot standing in the fore. It made so slow progress on this account that the passage from Saostrovskoj to Yenisejsk occupied a whole month. [Illustration: CHUKCH VILLAGE ON A SIBERIAN RIVER. (After a Photograph.) ] The two main arms into which the Yenisej is divided south of Yenisejsk are too rapid for the present Yenisej steamers to ascend them, while, as has been already stated, there is no difficulty in descending these rivers from the Selenga and the Baikal Lake on the one hand, and from the Minusinsk region abounding in grain on the other. The banks here consist, in many places, of high rocky ridges covered with fine forests, with wonderfully beautiful valleys between them, covered with luxuriant vegetation. What I have said regarding the mode of travelling up the Yenisej refers to the year 1875, in which I went up the river accompanied by two Swedish naturalists and three Norwegian seamen. It was then by no means unknown, for scientific men such as HANSTEEN (1829), CASTREN (1846), MIDDENDORFF (winter journeys in 1843 and 1844), and SCHMIDT (1866), had travelled hither and communicated their observations to the scientific world in valuable works on the nature and people of the region. But the visits of the West-European still formed rare exceptions; no West-European commercial traveller had yet wandered to those regions, and into the calculations of the friendly masters of the Yenisej river steamers no import of goods from, or export of goods to, Europe had ever entered. All at once a new period seemed to begin. If the change has not gone on so fast as many expected, life here, however, is more than it was at one time, and every year the change is more and more noticeable. It is on this account that I consider these notes from the journey of 1875 worthy of being preserved. [Footnote 200: With this name, for want of another, I denote all the innumerable islands which lie in the Yenisej between 69 deg. 45' and 71 deg. N.L. ]
