John Jay was a member of the first Congress, which assembled at Philadelphia in September, 1774, having been, with four other persons, chosen a delegate from the city and county of New York. He was also in the Congress of the following year, but after the organization of the government of New York he was made Chief Justice of the State, and retired from Congress. On the 21st of October, 1778, even while he held the office of Chief Justice, he was elected by the Assembly a delegate to Congress for a specific object, till the first of March following. The Assembly at the same time declared, that by the constitution of New York both these stations were consistent with each other. Mr Jay joined the Congress on the 7th of December, and was elected President of that body three days afterwards, as the successor of Henry Laurens. He discharged this office with great dignity and credit to himself till September 27th, 1779, when he was appointed Minister Plenipotentiary to negotiate a treaty of amity and alliance with Spain. He sailed for France about the first of November in the same ship with M. Gerard, who had been the late French Minister in the United States. Accidents at sea compelled the Captain of the vessel to put into Martinique, whence Mr Jay sailed in another vessel for Europe, and arrived at Cadiz on the 22d of January, 1780. Here he remained between two and three months, and then proceeded to Madrid, and entered on the duties of his mission. The two principal objects, which Mr Jay was instructed to obtain, were a grant of aids in money and military supplies from Spain, to assist in prosecuting the war against the common enemy, and a treaty between Spain and the United States. After encountering for more than two years innumerable embarrassments, vexatious delays, cold treatment, and a provoking indifference, that would have exhausted the patience, if not ruffled the temper of most men, he met with very little success in the former object, and none at all in the latter. The Spanish Court seemed nowise inclined to recognize the independence of the United States, or to show them any substantial marks of friendship, and yet there was evidently a willingness to keep on terms, and be prepared to act according to the issue of events. Tardy promises of money were made by the Minister, which he was reluctant to fulfil, and it was with extreme difficulty at last, that Mr Jay succeeded in procuring from his Catholic Majesty the pitiful loan of one hundred and fifty thousand dollars. In the treaty he made no progress, but was put off from time to time, with pretences as frivolous as they were insincere. He was never received in his public capacity, nor in any other character than that of a private gentleman empowered to act as Agent for the United States. In short, it must be confessed, that the conduct of Spain, in regard to this country during the revolutionary war, was not such as to inspire the gratitude or respect of succeeding generations.
