effect of the British navigation act on our carrying business. The returns in French instead of English manufactures, will take place by degrees. Supposing that these details cannot but be agreeable to you as a merchant and as an American, I trouble you with them; being with much sincerity, and on all occasions, dear Sir, your friend and servant. TO MONSIEUR DUMAS. PARIS, December 9, 1787. SIR,--Your letter of November 27, showing that mine of November 14, had not then got to hand, had given me alarm for its fate, and I had sat down to write you a second acknowledgment of the receipt of your two favors of October 23 and 26, and to add the receipt, also, of those of November 14, 22 and 27. A copy of my answer of November 14 was prepared to be enclosed to you, but in that moment came your favors of November 30, December 2d and 4th, by which I perceived that the original had at length got safe to hand. By that you have seen all that interference, direct or indirect, on the part of Mr. Adams and myself in the business you had done me the honor to suggest, would be improper. Your despatches for Mr. Jay shall go with mine in the packet of this month. These will bring the matter into the view of Congress. In the meantime I think it would be well to avoid exciting at Brussels or anywhere else the least expectation thereon, because it is impossible for us to know what that body may, in its wisdom and with all circumstances under its eye, decide should be done. They had, in the year 1784, made up their minds as to the system of commercial principles they wished to pursue. These were very free. They proposed them to all the powers of Europe. All declined except Prussia. To this general opposition they may now find it necessary to present a very different general system to which their treaties will form cases of exception, and they may wish to lessen rather than multiply those cases of exception. Add to this, that it is in contemplation to change the organization of the federal government, and they may think it better to leave the system of foreign connection to be formed by those who are to pursue it. I only mention these as possible considerations, without pretending to know the sentiments of that honorable body, or any one of its members on the subject; and to show that no expectations should be raised which might embarrass them or embroil ourselves. The proposed change of government seems to be the proper topic to urge as the reason why Congress may not at this moment choose to be forming new treaties. Should they choose it, on the other hand, the reserve of those who act for them, while uninstructed, cannot do injury.
