On the 7th instant we received your Excellency's letter of the 16th of June last, covering a resolution of Congress of the 1st of May, directing a commission to us for making a treaty of commerce, &c. with Great Britain. This intelligence arrived very opportunely to prevent the anti-American party in England from ascribing any delays, on our part, to motives of resentment to that country. Great Britain will send a Minister to Congress, as soon as Congress shall send a Minister to Britain, and we think much good might result from that measure. The information of M. Dumas, that we encouraged the idea of entering into engagements with the Dutch, to defend the freedom of trade, was not well founded. Our sentiments on that subject exactly correspond with those of Congress; nor did we even think or pretend, that we had authority to adopt any such measures. We have reason to think that the Emperor, and Russia, and other commercial nations, are ready to make treaties of commerce with the United States. Perhaps it might not be improper for Congress to direct, that their disposition on the subject be communicated to those Courts, and thereby prepare the way for such treaties. The Emperor of Morocco has manifested a very friendly disposition towards us. He expects, and is ready to receive a Minister from us; and as he may either change his mind, or may be succeeded by a prince differently disposed, a treaty with him may be of importance. Our trade to the Mediterranean will not be inconsiderable, and the friendship of Morocco, Algiers, Tunis, and Tripoli may become very interesting, in case the Russians should succeed in their endeavors to navigate freely into it by Constantinople. Much, we think, will depend on the success of our negotiations with England. If she should be prevailed upon to agree to a liberal system of commerce, France, and perhaps some other nations, will follow her example; but if she should prefer an exclusive, monopolizing plan, it is probable that her neighbors will continue to adhere to their favorite restrictions. Were it certain that the United States could be brought to act as a nation, and would jointly and fairly conduct their commerce on principles of exact reciprocity with all nations, we think it probable that Britain would make extensive concessions. But, on the contrary, while the prospect of disunion in our councils, or want of power and energy in our executive departments exist, they will not be apprehensive of retaliation, and consequently lose their principal motive to liberty. Unless, with respect to all foreign nations and transactions, we uniformly act as an entire united nation, faithfully executing and obeying the constitutional acts of Congress on those subjects, we shall soon find ourselves in the situation in which all Europe wishes to see us, viz. as unimportant consumers of her manufactures and productions, and as useful laborers to furnish her with raw materials.
