Both the youths shook their heads and said they didn't know, while Doctor Bronson preserved a discreet silence.
"The oukhaba of the Siberian road," Mr. Hegeman explained, "is the equivalent of the 'hog-wallow' of the American one; the former is formed in the snow, and the latter in the bare ground. It is caused by the snow lying in drifts or ridges when it is blown by the wind, and also by the roads being worn with much travel. The road is a succession of ridges and hollows; the drivers go at full speed, without the slightest regard to the pitching and tossing of the sleigh, and the result is a severe trial of one's nerves. The motion causes a rush of blood to one's head, and develops what the Russians call 'the road-fever.'
"I did not escape the road-fever, and to this day I shudder when thinking of this part of my experience, the most disagreeable feature of the journey. My body was sore and stiff; at every jolt it seemed as though the top of my head would fly off; sleep was next to impossible; and when I did manage to slumber, my dreams were something frightful. My temper was spoiled, and a quarrel might have been created with anything and anybody without the least effort. The fever runs its course in two or three days, but may last longer; as long as the roads are bad the inexperienced traveller is liable to it. Sometimes the sleigh made a clear jump of five or six feet, and the wonder was that the vehicle did not go to pieces and leave us hopelessly wrecked."
Fred asked if any wolves were seen in this part of the journey or elsewhere in Siberia.
"Occasionally we saw wolves," was the reply, "but not often. There are plenty of wolves in Siberia, but they have enough to live upon in the game that abounds everywhere, so that they are not likely to attack travellers. Siberian and American wolves are much alike, but the former are said to be larger and fiercer than their American cousins.
"I can tell you some wolf stories, but they do not belong to Siberia. It is only in Western Russia and in Poland that travellers are attacked by wolves, and then only in the severest winters, when game is very scarce and hunger has made the animals desperate."
"Please tell us one of those stories," said Frank. "I have read accounts of men being chased by wolves, but have just now forgotten what they were."
The request was echoed by Fred, and Mr. Hegeman kindly gratified their wish.
"To begin with," said he, "the horses are the object of attack and not the men in the vehicle; but of course when the horses are overpowered
