The third and last "difficulty" which I will speak of in this opening chapter, and which is no difficulty at all, is the passport. Every one in Russia must possess one; and, if travelling and intending to spend one or two nights in a place, it must be sent to the proper official and be duly stamped. It must be _vised_ by the Russian ambassador, or minister, at the place from which one starts before entering Russia; and, which is even more important, it must be _vised_ by the right official at some important town or place of government, and stamped with the necessary permission, before one is able to _leave_ Russia. It is natural to feel at the frontier, when entering the country, "I hope it is all right," as the passport is handed to the customs officer, and, with just a little approach to anxious uncertainty, after all one has heard and read; but it is almost impossible to avoid real anxiety that it will be found correct and in order as it is presented at the frontier when _leaving_, as the difficulties of being kept back there, so far away from the great cities, would be far greater than those of being refused _admission_ from some technicality that could probably be put right by a telegram to and from England. "But surely the passport must prevent you from feeling that sense of freedom that you have spoken of more than once--surely _that_ must give a sense of repression and suspicion and being watched and having an eye kept on your doings," my reader will be thinking, and perhaps many other people have the same feeling. It is, however, exactly the opposite with me, for my passport in Russia and Siberia is a great stand-by, and gives me a great sense of being always able to establish my own identity. There can be little doubt that the passport was established from the first in the interests of the community, for it is entirely in their own interests that people should possess them. No one who is honest in purpose can have any difficulty in procuring one or be brought to any trouble through it. The necessity of frequently producing them, in moving from place to place, is always in the interests of the traveller in a vast empire like Russia. It has given me a great feeling of confidence in launching out, as has been necessary now and then, into the unknown, to feel "They will be able to trace me all along by the entries made in official registers, as the passport has been stamped." If any one disappeared in Russia the police would be able to trace his movements to very near the place of disappearance.
