EUROPE-ASIA—THE RUSSIAN EMPIRE
The great plain of Eurasia, which borders about half the circuit of the Arctic Ocean, is undivided by topographic barriers or boundaries. It is physically a unit.
Russia.—Russia comprises more than one-half the area of Europe; the Russian Empire embraces about one-half of Europe and Asia combined, and constitutes more than one-seventh of the land surface of the earth. East and west, from St. Petersburg to Vladivostok, the distance is about six thousand miles. It has a similar position with respect to southern Europe and China as has Canada to the United States.
