"The fact must be obvious to the far-reaching minds of our Statesmen, that unless some means of relief be devised, some channel afforded, by which the South can, when the time comes, get rid of the excess of her slave population, she will be ultimately found with regard to this institution, in the predicament of the man with the wolf by the ears; too dangerous to hold on any longer, and equally dangerous to let go. To our mind, the event is as certain to happen as any event which depends on the contingencies of the future, viz.: that unless means be devised for gradually relieving the slave States from the undue pressure of this class upon them--unless some way be opened by which they may be rid of their surplus black population--the time will come--it may not be in the next nor in the succeeding generation--but, sooner or later, come it will, and come it must--when the two races will join in the death struggle for the mastery." THE VOICE OF BIRNEY. James G. Birney, of Kentucky, under whom the Abolitionists first became a National Party, and for whom they voted for President in 1844, giving him 66,304 votes, says: "We have so long practiced injustice, adding to it hypocrisy, in the treatment of the colored race, both negroes and Indians, that we begin to regard injustice as an element--a chief element--the chief element of our government. But no government which admits injustice as an element can be a harmonious one or a permanent one. Harmony is the antagonist of injustice, ever has been, and ever will be; that is, so long as injustice lasts, which cannot always be, for it is a lie, a semblance, therefore, perishable. True, from the imperfection of man, his ambition and selfishness, injustice often finds its way incidentally into the administration of public affairs, and maintains its footing a long time before it is cast out by the legitimate elements of government." "Our slave States, especially the more southern of them, in which the number of slaves is greater, and in which, of course the sentiment of injustice is stronger than in the more northern ones, are to be placed on the list of decaying communities. To a philosophic observer, they seem to be falling back on the scale of civilization. Even at the present point of retrogression, the cause of civilization and human improvement would lose nothing by their annihilation." THE VOICE OF DELAWARE. Strong anti-slavery sentiment had become popular in Delaware as early as 1785. With Maryland and Missouri, it may now be ranked as a semi-slave State. Mr. McLane, a member of Congress from this State in 1825, said:--
