TO GENERAL JOHN MASON.

Although the decree of the French government of November 21st comprehended, in its literal terms, the commerce of the United States, yet the prompt explanation by one of the ministers of that government that it was not so understood, and that our treaty would be respected, the practice which took place in the French ports conformably with that explanation, and the recent interference of that government to procure in Spain a similar construction of a similar decree there, had given well-founded expectation that it would not be extended to us; and this was much strengthened by the consideration of their obvious interests. But the information from our minister at Paris now communicated to Congress is, that it is determined to extend the effect of that decree to us; and it is probable that Spain and the other Atlantic and Mediterranean States of Europe will co-operate in the same measure. The British regulations had before reduced us to a direct voyage to a single port of their enemies, and it is now believed they will interdict all commerce whatever with them. A proclamation too of that government (not officially, indeed, communicated to us, yet so given out to the public as to become a rule of action with them,) seems to have shut the door on all negotiation with us, except as to the single aggression on the Chesapeake.

The sum of these mutual enterprises on our national rights is that France, and her allies, reserving for further consideration the prohibiting our carrying anything to the British territories, have virtually done it, by restraining our bringing a return cargo from them; and Great Britain, after prohibiting a great proposition of our commerce with France and her allies, is now believed to have prohibited the whole. The whole world is thus laid under interdict by these two nations, and our vessels, their cargoes and crews, are to be taken by the one or the other, for whatever place they may be destined, out of our own limits. If, therefore, on leaving our harbors we are certainly to lose them, is it not better, as to vessels, cargoes, and seamen, to keep them at home? This is submitted to the wisdom of Congress, who alone are competent to provide a remedy.
