Mr. Hillhouse rose and said, the subject now under consideration was one of the first in magnitude he had ever been called to deliberate upon, and that the circumstances under which it came up were peculiar, for previous to the Treaty's being either promulgated or known, a hue-and-cry had been raised, and the prejudices of the people as much as possible excited against it, and he confessed it had not been without its effect upon his own mind. When the Treaty came out, therefore, he was led to examine it with attention, compare it with our Treaties with other nations, and those between Great Britain and other nations; the result of this inquiry was, that he found that no privilege or advantage given by Great Britain to the other nations was withheld from us; that advantages were secured to us which were enjoyed by no other nation, nor even by her own subjects: that we gave her little that was not enjoyed by every other nation; and, on the whole, that it was as good a Treaty as we had a right to expect, and as he had ever expected to obtain. He was sensible that prejudice, which, like a sentinel at the door of the human mind to keep out truth and argument, had induced many good citizens of the United States at first to be opposed to the Treaty, who, upon being prevailed on to give it a more candid examination, had declared in favor of it; but he hoped the Representatives of the people, called to decide on a question which might affect the dearest interests of millions, would, as much as possible, divest themselves of prejudice and passion: to do it entirely, he believed, was impossible.

The first, and, if well-founded, the most important objection which he had heard made against the Treaty was, that a claim for negroes and other property carried away from New York had been wholly overlooked or given up by our Minister. Here, he said, he was sensible any argument he might adduce would be opposed by the party opinions formed at the time—when judging in our own case, and when we felt a great degree of sensibility for the losses and injuries we had recently experienced. He was not unapprised that Congress had claimed that the construction of the 7th article of the Treaty was such as to require the delivering up of the negroes, and had passed the resolution read by the gentleman from Virginia, (Mr. Heath,) and that that opinion had, without examination, been implicitly followed by many respectable characters; but he hoped at this distance of time, he might expect a candid hearing, whilst he examined their arguments and the law of nations, to which alone resort can be had to decide differences between sovereign and independent nations. To his mind they were conclusive that we had not a well-founded claim; to every mind, he believed, they would render the claim at least doubtful.

His first inquiry, he said, should be, whether negroes were to be considered as property? This, he believed, must be admitted: they were thus recognized by the article itself, which says "negroes or other property." Negroes being mentioned amounts only to a specification of one kind of property; as, in the constitution, it says "capitation or other direct taxes," which is a conclusive recognition that a capitation tax is a direct tax, within the meaning of the constitution. Upon no other ground than that of property could the United States claim them; as men, they had a right to go where they pleased. Our commissioners, at the time of the embarkation, had no hesitation in declaring that they considered "negroes, horses, and other property," as being precisely on the same footing, and selected a claim for a horse as one of the strongest that could be found to enforce a compliance with this construction of the article. The claim was in these words:

"Mr. Vanderburgh had a horse stolen from him, out of his stable in Beekman's Precinct, in Dutchess County, 26th February, 1780, and the horse was conveyed by the person who stole him to a then British post, in Westchester County, where he has since been detained; so that Mr. Vanderburgh could not recover him again. The horse is now in the possession of Col. James De Launcy, of this city, from whom Mr. Vanderburgh has demanded him, and who refuses to deliver him to Mr. Vanderburgh."

In the letter of the Commissioners to General Washington, on this subject, they say:

"In the interview between the 15th and 24th, numbers applied to us for a restitution of their negroes and other property in the possession of others, but we supposed it most eligible to defer a requisition till a clear unequivocal case, similar to that of Mr. Vanderburgh's, where the proofs were at hand and not embarrassed with the circumstances of a capture in war or other pretences under which property is withheld here, should present itself; sensible that if restitution was denied in such an instance, it would inevitably be in every other."

It therefore appears clear that negroes, horses, and other property, were, by this article, placed upon the same footing, and that it was as much a violation of the Treaty to carry away a horse as a negro.

He next proceeded to inquire what was the situation of this property, and in whom, according to the law of nations, it was vested at the time of executing the Treaty? This point, he said, Mr. Jefferson had fully settled to his hand, and read out of his collection the following extracts:

"We now come together (says Mr. Jefferson) to consider that instrument which was to heal our wounds, and begin a new chapter in our history. The state in which they found things is to be considered as rightful; so says the Law of Nations.—Vattel. The state in which things are found at the moment of the Treaty, should be considered as lawful, and if it is meant to make any change in it, the Treaty must expressly mention it. Consequently, all things about which the Treaty is silent, must remain in the state in which they are found at its conclusion.—Bynk. Since it is a condition of war that enemies may be deprived of all their rights, it is reasonable that every thing of an enemy's, found among his enemies, should change its owners, and go to the Treasury. It is moreover usually directed, in all declarations of war, that the goods of enemies, as well those found among us as those taken in war, shall be confiscated."

These authorities, he said, clearly proved that all negroes and other property which in the course of the war had been taken, or in any way had fallen into the hands of the British, had shifted their owner, and were no longer the property of the American inhabitants. In the case of negroes, the British Commander-in-Chief had exercised the highest act of ownership, by manumitting such of them as should conform to certain stipulations, pointed out in his proclamation. If any change was intended to have been made by the Treaty in the circumstances of these negroes, and it had been intended they should be again returned into bondage, there would have been some express stipulation to that effect in the Treaty. The words are, "and without causing any destruction, or carrying away any negroes or other property of the American inhabitants, withdraw all his armies," &c. There is nothing that indicates the least intention that this article should have a retrospective operation. It can only relate to property then belonging to the American inhabitants. Wherever any article was intended to have a retrospective operation, some expression is used that clearly shows such intention. In this same article, speaking of delivering up records, deeds, &c., these words are added, "which in the course of the war may have fallen into the hands of his officers," &c. In the 4th article, "debts heretofore contracted." Any other construction would have required the restoration of vessels which had been taken from the Americans, and were then in New York, under the term "other property," as well as negroes and horses. If any negroes or other property, in the possession of the American inhabitants at or after signing the preliminary articles, were carried off, it was no doubt a violation of the Treaty, but he had not understood that they refused to deliver up property of that description, or that such property was carried off to any great amount.
