Michael Strogoff and the young Livonian had taken a passage on board the Caucasus. Their embarkation was made without any difficulty. As is known, the podorojna, drawn up in the name of Nicholas Korpanoff, authorized this merchant to be accompanied on his journey to Siberia. They appeared, therefore, to be a brother and sister traveling under the protection of the imperial police. Both, seated together at the stern, gazed at the receding town, so disturbed by the governor's order. Michael had as yet said nothing to the girl, he had not even questioned her. He waited until she should speak to him, when that was necessary. She had been anxious to leave that town, in which, but for the providential intervention of this unexpected protector, she would have remained imprisoned. She said nothing, but her looks spoke her thanks.
The Volga, the Rha of the ancients, the largest river in all Europe, is almost three thousand miles in length. Its waters, rather unwholesome in its upper part, are improved at Nijni-Novgorod by those of the Oka, a rapid affluent, issuing from the central provinces of Russia. The system of Russian canals and rivers has been justly compared to a gigantic tree whose branches spread over every part of the empire. The Volga forms the trunk of this tree, and it has for roots seventy mouths opening into the Caspian Sea. It is navigable as far as Rjef, a town in the government of Tver, that is, along the greater part of its course.
The steamboats plying between Perm and Nijni-Novgorod rapidly perform the two hundred and fifty miles which separate this town from the town of Kasan. It is true that these boats have only to descend the Volga, which adds nearly two miles of current per hour to their own speed; but on arriving at the confluence of the Kama, a little below Kasan, they are obliged to quit the Volga for the smaller river, up which they ascend to Perm. Powerful as were her machines, the Caucasus could not thus, after entering the Kama, make against the current more than ten miles an hour. Including an hour's stoppage at Kasan, the voyage from Nijni-Novgorod to Perm would take from between sixty to sixty-two hours.
The steamer was very well arranged, and the passengers, according to their condition or resources, occupied three distinct classes on board. Michael Strogoff had taken care
