Of course literature made no direct appeal to creatures of such sort. But there were many educated or at least literate negroes at the South--some of them slaves and some of them "free men of color" as the law phrase at that time ran. If incited thereto, these intelligent blacks might very easily have organized the physical force of the multitude of more ignorant negroes for an insurrection which would have involved the wholesale slaughter of white women and children and a servile war more horrible in its incidents and consequences than any that the world has known since time itself began. It was altogether natural that the anti-slavery agitators who had made up their minds to destroy slavery at all hazards and at all costs and who held all other considerations to be but as dust in the balance in comparison with that one supreme desire of their souls, should seek by means of the mails to propagate their ideas in the South and among the slaves themselves. But it was equally natural that the white men of the South, whose wives and children as well as themselves and their property were menaced by such a possibility, should seek to avert it by any means within their grasp. Their impulse was dictated by the primal human instinct of self-preservation--an instinct that listens to no argument and stops at no act which may be necessary to avert the impending danger. These people saw their hearthstones menaced by this use of the mails. They saw in the mails a certain socialistic use of the people's power for a common purpose. They paid taxes for the maintenance of those mails, and they could not see why a mail system which represented and was supported by all the people of all the states should be used for the destruction and desecration of the homes of a part of those people--for the instigation of a servile revolt which could not fail to result in horrors so unspeakable that we may not even suggest them, except vaguely, in this place. Since that time it has become a commonplace of law to forbid the use of the mails to those who would use them for any purpose inimical to the public welfare; but at that time this thought had gained no place in postal administration, and the desire of the Southerners to purge the mails of incendiary literature which threatened to create a servile insurrection with all its necessarily horrible accompaniments, was put aside as an effort to "tamper with the mail." Contrary to all modern conceptions as to the mails it was held that they were sacred alike to good and to evil purposes and that any matter deposited in them must be delivered to the person to whom it was addressed in utter disregard of any question of public polity and in absolute indifference to the use which the person addressed might be disposed to make of the printed or written matter sent to him.
