When, for this purpose, after a short adjournment, the convention met at the Windsor meeting-house, all Vermont was in alarm at the British invasion which was sweeping upon its western border. Almost at first the attention of the delegates was called to the impending peril of Ticonderoga by an appeal for aid from Colonel Warner. This was at once forwarded to the Assembly of New Hampshire, and such measures as seemed best, which elicited the warm thanks of General St. Clair, were taken by the convention for the relief of the threatened fortress. Some of the members, among whom was the president, the patriotic Joseph Bowker of Rutland, whose families were in exposed situations, were now anxious for an adjournment; but a furious thunder-storm came roaring up the Connecticut valley, and the storm-bound convention took up its appointed work, reading and adopting, one by one, the articles of the Constitution amid the turmoil of the tempest. To the first section of the declaration of rights, which announced that "glittering generality," the natural rights of man to life, liberty, and the pursuit of happiness, this specific clause was added: "Therefore no male person born in this country, or brought from over sea, ought to be holden by law to serve any person as a servant, slave, or apprentice after he arrives to the age of twenty-one years, nor female in like manner after she arrives to the age of eighteen years, unless they are bound by their own consent after they arrive to such age, or bound by law for the payment of debts, damages, fines, costs, or the like." "Vermont was thus the first of the States to prohibit slavery by constitutional provision, a fact of which Vermonters may well be proud," says Hiland Hall in his "Early History."
