The facilities of intercourse between a people, for the transmission of intelligence, for travel and transportation--those accompaniments of civilization which bring remote sections of country near each other and bind them together; the resemblance or the difference of languages spoken; the antipathies, prejudices, sympathies of the peoples--all these are elements which go to determine the geographical extent of a nation. Original difference of language, local prejudices, the want of civilization, contributed to limit the European nationalities to the small extent of territory which, for the most part, they occupy. These causes have not operated against us. Local distinctions on account of language do not even obtain here. There are no real causes to contract the geographical boundaries of our Government; while, on the other hand, the constant increase of facilities for the commercial and social intercourse of one section with another, and the specializations of the agricultural, manufacturing, and commercial interests, in the creation of dependence between different sections of the country, demand, in the name of science, common sense, justice, and the good of the people, that this Government shall remain one and undivided. We cannot, therefore, afford to allow the present or any other rupture to become permanent, and entail upon ourselves and our children all the disadvantages and calamities incident thereto. It would not be wise to prepare the political stage of this country for the reenaction of the tragedies of Europe. Better any sacrifice than this. Even if we should lose great battles, or if European interference should threaten, it would be better to rally the people anew even to the raising and equipment of millions of men, and sustain the war at this enormous cost, rather than entail division and its necessary calamities on the future political life of this continent. This war is costing immensely in men and property; but if, thereby, the integrity of the Union can be maintained, it will be an economy both in men and means, if only a brief period of the future be taken into the account. We are often reduced to a choice of evils. War is a great evil, but it may prevent others still greater. The indiscriminate arming of slaves and the spread of incendiary fires would be great calamities, but nevertheless justifiable, if the only means of selfdefence, or of preventing still greater and more enduring calamities. But there need be no violation of the ethics of war, no infringement of the rights of humanity. The North is strong in its natural resources, strong in the justice of its cause: it has risen to vindicate the cardinal law of civilization, and by this shall it conquer. There appeared to Constantine a vision of the cross, with the motto, 'By this conquer.' Science has descended in these last days to dwell among mankind. In her hand is a scroll which she unfolds before the nations, and they read, 'Unity, the consummation of social
