There were earnest men already engaged in a new and more vigorous crusade: Elias Hicks, the Quaker, who proclaimed boldly the sin of owning men or condoning the practice in others; Rev. John Rankin, of Tennessee, who removed with his congregation across the Ohio River, rather than acquiesce in slavery; William Goodell, of Providence, beginning a career of forty years; above all, Benjamin Lundy, who sacrificed to the cause all that men hold dear. Between 1815 and 1818 four abolition papers were being published, The Emancipator in Tennessee, The Abolition Intelligencer in Kentucky, The Liberalist in Louisiana, and, most important, Lundy's Genius of Universal Emancipation in Maryland. All of these papers were published in the South, and the majority of the manumission societies were there. Thus, in 1826, when William Jay began his labours, the line between freedom and slavery was not yet drawn. A few slaves were still held in New York. Many antislavery people were to be found at the South and many pro-slavery people at the North. The United States was a slaveholding nation.

Jay was a deeply interested observer of the contest in Congress which resulted in the Missouri Compromise. In 1819, when he was thirty years of age, his attitude towards the extension of slavery was stated in a letter to Elias Boudinot:

"I have no doubt that the laws of God, and, as a necessary and inevitable consequence, the true interests of our country, forbid the extension of slavery. If our country is ever to be redeemed from the curse of slavery the present Congress must stand between the living and the dead and stay the plague. Now is the accepted time, now is the day of salvation. If slavery once takes root on the other side of the Mississippi, it can never afterwards be extiminated, but will extend with the future Western Empire, poisoning the feelings of humanity, checking the growth of those principles of virtue and religion which constitute alike the security and happiness of civil society."

In the year 1826 occurred an incident which marks the beginning of a new phase in the antislavery struggle—the movement which demanded abolition in the District of Columbia. There, on territory exclusively under the jurisdiction of the National Congress, it could be claimed justly that the question of States rights was not involved and that the constitutional provisions did not apply. In this movement, which continued until its object was accomplished in April, 1862, William Jay was a pioneer.

In August of the year 1826 John Owen, the proprietor of a paper-mill at Croton Falls, near the Jay farm at Bedford, received a parcel from New York which happened to have been wrapped in a Washington newspaper, The National Intelligencer, of the 1st of August. On looking it over his eye was caught by the following advertisement:

"Was committed to the jail of Washington County, District of Columbia, on the 22d of July last, a runaway negro man by the name of Gilbert Horton. He is five feet high, stout made, large full eyes, and a scar on his left arm near the elbow; had on when committed a tarpaulin hat, linen shirt, blue cloth jacket and trousers; says that he was born free in the State of New York near Peekskill. The owner or owners of the above-described negro man, if any, are requested to come and take him away, or he will be sold for his jail fees and other expenses, as the law directs."

There is a sort of grim humour about this advertisement, appearing, as it did, according to law, in the capital of the great free republic of the world, under a flag supposed to typify human liberty. It declared that a man who claimed to be and actually was a citizen of the State of New York was held in jail without any charge and would be sold into lifelong slavery unless claimed as a slave by an owner who did not exist. It declared, in short, that a free citizen of the United States who had any negro blood in his veins would be reduced to slavery by the act of setting foot in the capital of his country. Here was an issue which involved the rights of the State of New York, but could not be said to be an attack on those of Virginia or South Carolina.

Mr. Owen recognized in the Gilbert Horton thus described a free man who had worked in his neighbourhood. He lost no time in mounting his horse and riding over to Bedford to submit the matter to Judge Jay. By the latter's advice a letter was despatched at once to the marshal of the District of Columbia, giving proofs of Horton's freedom, and a meeting was called of the citizens of Westchester County to take action on the subject. This meeting, held on the 30th of August, with Oliver Green in the chair and William Jay as secretary, passed the following resolutions:

"I. That this meeting view this procedure with the indignation becoming men who have a just sense of the value of personal liberty, and a proper abhorrence of cruelty and oppression.

"II. That the evidence affords unequivocal proof of the freedom of Horton.
