“I will follow you, brother,” replied the girl, putting her hand into that of Michael Strogoff. And together they left the police station. CHAPTER VII GOING DOWN THE VOLGA A LITTLE before midday, the steamboat’s bell drew to the wharf on the Volga an unusually large concourse of people, for not only were those about to embark who had intended to go, but the many who were compelled to go contrary to their wishes. The boilers of the Caucasus were under full pressure; a slight smoke issued from its funnel, whilst the end of the escape-pipe and the lids of the valves were crowned with white vapor. It is needless to say that the police kept a close watch over the departure of the Caucasus, and showed themselves pitiless to those travelers who did not satisfactorily answer their questions. Numerous Cossacks came and went on the quay, ready to assist the agents, but they had not to interfere, as no one ventured to offer the slightest resistance to their orders. Exactly at the hour the last clang of the bell sounded, the powerful wheels of the steamboat began to beat the water, and the Caucasus passed rapidly between the two towns of which Nijni-Novgorod is composed. 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.
