And the fact continued that a coloured citizen of a free State could be sold into slavery if found in Washington. Convinced that no reform could be expected except by the total abolition of slavery on United States territory, convinced, too, that this was the first necessary step in a campaign against slavery itself, Jay set on foot a movement for popular petitions to Congress and for legislative expression in behalf of their consideration. The Pennsylvania Legislature passed such resolutions in January, 1829; the New York Assembly followed soon afterwards, when Jay wrote to his friend Charles Miner: "The mail this evening brings the news that resolutions instructing our representatives in Congress to vote for the abolition of slavery in the District of Columbia have passed our Assembly by a vote of 57 to 39. In the fulness of my heart I thank God and take courage." Among his co-workers at this time was Henry D. Sedgwick, to whom he wrote in 1831: "I have read your pamphlet with much interest; your ideas on the abolition of slavery correspond with those I have long entertained and expressed. Duty is the only safe rule of expediency. No nation ever has suffered, and none ever will, for doing justice and loving mercy. But moral considerations apart, I have no doubt it would be wise policy in the Southern States immediately to emancipate their slaves. The period must arrive when slavery must cease on this continent. The progress of knowledge and religion, the example of St. Domingo, the abolition of slavery in Mexico and South America, the decreasing value of slave labour, and the rapidly augmenting coloured population in the South, all combine in rendering this event inevitable. But the slaves will either receive their freedom as a boon, or they will wrest it by force from their masters; and the evils attending these two modes of emancipation certainly bear no proportion to each other. You remark, 'Our country fought for justice and should be ready to render the justice which it demanded.' I observe a similar sentiment in a letter written by my father from Spain to Judge Benson during the contest to which you allude. Speaking of the abolition of slavery, he says, 'Till America comes into this measure her prayers to Heaven for liberty will be impious.' This is a strong expression, but it is just. Were I in your Legislature I would prepare a bill for the purpose with great care, and would never cease moving it till it became a law or I ceased to be a member. I believe that God governs the world, and I believe it to be a maxim in His Court, as in ours, that those who ask for equity ought to do it. I do not think the free States guiltless of upholding slavery while, through their representatives, they tolerate it in the District of Columbia. Were the free States to will it, slavery would cease at the capital of the republic, and an example would be set that could not fail of having a salutary influence."
