For the first two stages from Irkutsk we caught occasional glimpses of high mountain ranges at a great distance to the south-west. But the dense forest soon shut in our view. The roads were tolerably good, and we rumbled along expeditiously and comfortably. The country maintains the same characteristics as already noted--thick woods for the most part, with clear patches here and there, and villages at intervals of a few miles; while its surface is pleasantly varied with hill and dale, and if only there were less forest to enable one to see round him, it would be a very cheerful drive. Innumerable small rivers have to be crossed in ferry-boats, which help to break the monotony of the journey. Reading is next to impossible on Russian roads, and the art of sleeping--when there is nothing better to do--is a most valuable accomplishment to the traveller. We had attained considerable proficiency in this, and I have been ferried across a river amid the hubbub of taking out and putting in horses, and rolling the carriage into and out of the ferry-boat, without suffering any interruption of a profound slumber. Being eager to make up lost time, we drove our yemschiks hard with drink-money, and they certainly responded heartily to the stimulant. The roads are very steep, and nothing has been done in the way of cuttings or embankments. The ravines have generally small streamlets running along the bottom, which is ragged and broken. These are bridged over in a rough-and-ready manner. But the ascents and descents are fearfully steep. When a heavy carriage starts down a hill with three rats of ponies in front of it, one only bearing the weight of the vehicle, no earthly power can stop it. The drag on the wheel is of little use. The only safety is in the plan the Russian drivers adopt of going full tilt from top to bottom, to the delight of Siberian ponies--dashing over the wooden bridge like madmen, and halfway up the opposite hill before they draw rein. There is a fascinating excitement about this mode of charging a ravine which kills all sense of danger, except, perhaps, when the road is slippery with snow, well polished with sledges. Under these circumstances it is only the more necessary to urge the beasts at top speed; but a qualm of nervousness will occasionally rise, unbidden, until you have learned to confide implicitly in the infallibility of the yemschiks and their high-mettled steeds.
