There was scarcely a city in the North, from New York to San Francisco, whose Colored residents did not speedily offer their services to the States to aid in suppressing the Rebellion. But everywhere as promptly were their services declined. The Colored people of the Northern States were patriotic and enthusiastic; but their interest was declared insolence. And being often rebuked for their loyalty, they subsided into silence to bide a change of public sentiment. The almost unanimous voice of the press and pulpit was against a recognition of the Negro as the cause of the war. Like a man in the last stages of consumption who insists that he has only a bad cold, so the entire North urged that slavery was not the cause of the war: it was a little local misunderstanding. But the death of the gallant Col. Elmer E. Elsworth palsied the tongues of mere talkers; and in the tragic silence that followed, great, brave, and true men began to think. Not a pulpit in all the land had spoken a word for the slave. The clergy stood dumb before the dreadful issue. But one man was found, like David of old, who, gathering his smooth pebble of fact from the brook of God's eternal truth, boldly met the boastful and erroneous public sentiment of the hour. That man was the Rev. Justin D. Fulton, a Baptist minister of Albany, New York. He was chosen to preach the funeral sermon of Col. Elsworth, and performed that duty on Sunday, May 26, 1861. Speaking of slavery, the reverend gentleman said: "Shall this magazine of danger be permitted to remain? _We must answer this question. If we say no, it is no!_ Slavery is a curse to the North. It impoverishes the South, and demoralizes both. It is the parent of treason, the seedling of tyranny, and the fountain-source of all the ills that have infected our life as a people, being the central cause of all our conflicts of the past and the war of to-day. What reason have we for permitting it to remain? God does not want it, for His truth gives freedom. The South does not need it, for it is the chain fastened to her limb that fetters her progress. Morality, patriotism, and humanity alike protest against it. "The South fights for slavery, for the despotism which it represents, for the ignoring the rights of labor, and for reducing to slavery or to serfdom all whose hands are hardened by toil.
