"The last word in the Eastern Question," said Lord Derby, "is Constantinople." If for Constantinople we read not merely the city itself, but that half of Turkey in Europe bordering upon the Black Sea and the Sea of Marmora, and understand the real point to be, Shall or shall not Russia have it? we have the whole Eastern Question in a nutshell. Russia is bound by every consideration of policy and interest to get it if she can. Great Britain is bound by every consideration of interest, and even of self-preservation, to prevent it if she can. Germany, Austria, and France are bound to prevent it, if possible, unless they can at the same time gain equivalent advantages which shall leave them relatively to each other, and especially to Russia, not less powerful than they now are. The other nations of Europe may be left out of view in considering the question; for their interest in it is less vital, and they could do little toward the result, except as allies to one side or the other, in case of a general European war in which the great Powers should be quite evenly balanced, when their comparatively small weight might turn the scale. A glance at the map will show the paramount importance to Russia of the acquisition of this territory. Comprising more than half of all Europe, she is practically cut off from the navigable seas. She has, indeed, a long coast-line upon the Arctic ocean, but she has there only the inconsiderable port of Archangel, and this can be reached only by rounding the North Cape and sailing far within the Arctic Circle, while the port itself is blocked up by ice seven months of the year. She also borders for seven hundred miles upon the Baltic and the Gulf of Bothnia; but here, in the northwestern corner of her territory, she has only two tolerable ports, Cronstadt and Riga, and these are frozen up for nearly half the year; but from these ports is carried on three-fourths of her foreign commerce. She next touches salt water in the Black Sea, almost 1,500 miles from St. Petersburg, on the extreme south of her territory. This sea, half of whose shores belongs to Russia, is 720 miles long, and 380 miles wide at its broadest point, covering an area, including the connected Sea of Azof, of nearly 200,000 square miles--more than twice that of all the great lakes of North America. Russia wishes to be a great maritime power. The Black Sea has good harbors and abundant facilities for building ships and exercising fleets. Into it fall all the great rivers of the southern half of Russia, except the Volga, whose mouth is in the Caspian; and the Volga may properly be considered a Black Sea river, for a railway, or perhaps even a canal of a few leagues, would connect it with the Don and the other rivers of the Black Sea system. The Black Sea is emphatically a Russian sea; but Russia enjoys the valuable use of it only by the sufferance of whomsoever holds Constantinople. By the treaty of Paris, concluded in 1856, after the
