required for the convenience and comfort with which the civilised man in our days can with difficulty dispense. Many perhaps believe that the present want of commercial communication may be removed by a railway running across Russia and Southern Siberia. But this is by no means the case. On the contrary, communication by sea is an indispensable condition of such a railway being profitable. For it can never come in question to carry on a railway the products of the forest or the field over the stretch of three to five thousand kilometres which separates the fertile river territory of the Ob-Irtisch from the nearest European port. Even if we suppose that the railway freight, inclusive of all costs, could be reduced to a farthing the kilometre-ton, it would in any case rise, from the grain regions of Siberia to a harbour on the Baltic, to from 4_l_. to nearly 7_l_. per ton. So high a freight, with the costs of loading in addition, none of the common products of agriculture or forestry can stand, as may easily be seen if we compare this amount with the prices current in the markets of the world for wheat, rye, oats, barley, timber, &c. But if the Siberian countryman cannot sell his raw products, the land will continue to be as thinly peopled as it is at present, nor can the sparse population which will be found there procure themselves means to purchase such products of the industry of the present day as are able to bear long railway carriage. In the absence of contemporaneous sea-communication the railway will therefore be without traffic, the land such as it is at present, and the unprosperous condition of the European population undiminished. In order to give the reader an idea of the present natural conditions, and the present communication on a Siberian river, I shall, before returning to the sketch of the voyage of the _Vega_, give some extracts from notes made during my journey up the Yenesej in 1875, reminding the reader, however, that the natural conditions of the Ob-Irtisch and the Lena differ considerably from those of the Yenisej, the Ob-Irtisch flowing through lower, more fertile, and more thickly peopled regions, the Lena again through a wilder, more beautiful, but less cultivated country. When one travels up the river from Port Dickson, the broad sound between Sibiriakoff's Island and the mainland is first passed, but the island is so low that it is not visible from the eastern bank of the river and which is usually followed in sailing up or down the river. The mainland, on the other hand, is at first high-lying, and in sailing along the coast it is possible to distinguish various spurs of the range of hills, estimated to be from 150 to 200 metres high, in the interior. These are free of snow in summer. A little south of Port Dickson they run to the river bank, where they form a low rock and rocky island projecting into the river, named after some otherwise unknown Siberian Polar trapper, Yefremov Kamen.
