"1. Throw off the old and assume a new designation--the Union party. Adopt the conciliatory measures proposed by Mr. Crittenden or the peace convention--and my life upon it, we shall have no new case of secession, but, on the contrary, an early return of many, if not of all, the States which have already broken off from the Union. Without some equally benign measure the remaining slave-holding States will probably join the Montgomery Confederacy in less than sixty days, when this city, being included in a foreign country, would require a permanent garrison of at least 35,000 troops to protect the government within it. "I stop here to call your attention to the fact that Maryland did not join the Montgomery Confederacy, and yet with Maryland on our side to-night, it requires a garrison of 150,000 men to protect Washington. "2. Collect the duties on foreign goods outside the ports of which this government has lost the command, or close such ports by act of Congress and blockade them. "3. Conquer the seceded States by invading armies. No doubt this might be done in two or three years by a young and able general--a Wolfe, a Desaix, or a Hoche, with 300,000 disciplined men, estimating a third for garrisons, and the loss of a yet greater number by skirmishes, sieges, battles, and Southern fevers. The destruction of life and property on the other side would be frightful, however perfect the moral discipline of the invaders. "The conquest completed at that enormous waste of human life to the North and Northwest, with at least $250,000,000 added thereto, and _cui bono_? Fifteen devastated provinces! not to be brought into harmony with their conquerors, but to be held for generations, by heavy garrisons, at an expense quadruple the net duties or taxes which it would be possible to extort from them, followed by a protector or an emperor. "4. Say to the seceded States, Wayward sisters, depart in peace! In haste, I remain, "Very truly yours, "WINFIELD SCOTT." "_Hon. Wm. H. Seward, &c., &c., &c._" J. L.
