Let us once surrender, through national verdancy, sentimental commiseration, misunderstanding of the nature and purposes of our enemy, or any or all of these causes combined with others, the dear-bought advantages we have won, and disasters untold involve the future of the land. Terrible beyond description will be, in that event, the condition of the Union and emancipationist party now incipiently developing itself at the South;--abandoned and deserted by the withdrawal of the actual presence and protection of Northern arms. No barbarism on earth, no savagism extant, is so barbarous or so savage as the ruthless vengeance with which this hybrid civilization of the South is ready at any time to visit the crime of abolitionism; and seven times hotter than usual will the furnace of their wrath be heated against Southern men who under the aegis of Northern protection shall have exhibited some sympathy with freedom. That a powerful Northern party will immediately arise in behalf of the simple readmission of the Southern States, upon precisely the old basis, when the war shall end by the suppression of the rebellion, is certain. The existence of such a party will rest, in part, upon a real sympathy with the South and the rebellion; partly upon interested political motives of a more ordinary and short-sighted character; and, in still greater part than either of these, upon the easy credence and insufficient information of the great mass of the Northern people; somewhat, indeed, upon a magnanimity highly creditable to their character as men, but unwise and dangerous in the extreme, in any exercise of it which should surrender a vital advantage. It does not require even that the complete reconquest of the South should be awaited in order that the question of the return of subdued States into the Union upon the old terms should be sprung upon the nation, and perhaps decided, by a precedent, before the attention of the country can be thoroughly directed to the momentous nature of the step proposed. The _New York Herald_ has been hitherto a steady and consistent advocate of this policy, and a powerful agitator in its behalf. The following extract from its columns indicates the imminence of the issue, as well as the simple and seemingly reasonable political machinery by which the whole thing is to be effected:
