These lands are surveyed at the expense of the government into town-ships of six miles square, subdivided into sections, and these into quarter sections (160 acres), set apart for homesteads. Our system of public surveys into squares, by lines running due north and south, east and west, is so simple as to have precluded all disputes as to boundary or title. This domain reaches from the 24th to the 49th parallel, from the lakes to the gulf, and from the Atlantic to the Pacific. Its isothermes (the lines of equal mean annual temperature) strike on the north the coast of Norway midway, touch St. Petersburg in Russia, and pass through Manchooria to the coast of Asia, about three degrees south of the mouth of the Amour river. On the south, these isothermes run through northern Africa, and nearly the centre of Egypt near Thebes, cross northern Arabia, Persia, northern Hindostan, and southern China near Canton. No empire in the world of contiguous territory possesses such a variety of climate, soil, forests, and prairies, fruits, and fisheries, animal, vegetable, mineral, and agricultural products. It has all those of Europe, and many in addition, with a climate, as shown by the international census, far more salubrious, with a more genial sun, and millions in other countries are already fed and clothed by our surplus products. Of this vast domain, less than two per cent. is cursed by slavery, which is prohibited by law in ten of these land States, and in all the Territories. Indeed, when the present rebellion shall be crushed, and this vast territorial region (accelerated by the Homestead bill) shall be settled and admitted as States, three fourths of the States will then be free States, and thus authorized by the Constitution to amend that instrument. Thus we can by just and lawful measures make emancipation universal. From the progress of events, we shall probably celebrate the 4th of July, 1876, our first centennial, now less than fourteen years distant, as a nation, of _freemen_, with slavery abolished or rapidly disappearing. State will then have succeeded State in unbroken column, from the Atlantic to the Pacific, united by imperial railroads traversing the continent. Adjacent regions, geographically connected with us, will then consummate the political union designed by Providence, The Homestead bill, having accomplished its great work within our present limits, will then commence a new career, and carry our banner in peaceful triumph, over the continent. Our Review, then, is called CONTINENTAL, as prefiguring the destiny of our country.
