The conduct of the mobs, and the encouragement given to them by the press, aroused the spirit and stimulated the energy of the abolitionists. "These crimes," said Judge Jay, "abundantly prove the extreme cruelty and sinfulness of that prejudice against colour which we are impiously told is an ordination of Providence. Colonizationists, assuming the prejudice to be natural and invincible, propose to remove its victims beyond its influence. Abolitionists, on the contrary, remembering with the Psalmist 'that it is He that hath made us, and not we ourselves,' believe that the benevolent Father of us all requires us to treat with justice and kindness every portion of the human family." Although he had been an earnest emancipationist for ten years, Judge Jay had had doubts of the wisdom of forming antislavery societies at so early a period in the movement. He had feared that unmeasured and unconstitutional doctrines might be adopted which would set the cause in a false light before the country. His advice had been sought and followed, as we have seen, and there was no longer any reason why he should not become an active member. In 1834, immediately after the riots and when the outlook seemed darkest, he took a place on the Executive Committee of the National Society. "In that season of feverish excitement," wrote Hon. Henry Wilson, "Judge William Jay, inheriting not only the honoured name, but the principles and purity of the illustrious Chief-Justice, at first declined an office in the new society, deeming its organization premature," but now "sought to take his share of its labours and responsibilities. His name gave prestige; his talents, learning, and integrity afforded strength, while his cautious and ready pen laid precious gifts upon its altar." In February, 1835, was published Jay's "Inquiry into the Character and Tendency of the American Colonization and American Antislavery Societies." The book bore upon its title-page the words of Milton, "Give me liberty to know, to utter, and to argue freely, according to my conscience, above all liberties"--a sentiment considered treasonable in America by the Slave Power. This work had a powerful effect upon public opinion, not only on account of the arguments it contained, but largely on account of the character and position of its author. It was the policy of the pro-slavery party to represent the abolitionists as ignorant and reckless agitators, with nothing to lose. But here was a man of family and fortune, a judge on the bench, high in the counsels of the Episcopal Church, who set forth the detested doctrines with judicial moderation and unanswerable logic.
