Whilst, however, the Government of the United States was awaiting the movements of the French Government in perfect confidence that the difficulty was at an end, the Secretary of State received a call from the French charge d’affaires in Washington, who desired to read to him a letter he had received from the French minister of foreign affairs. He was asked whether he was instructed or directed to make any official communication, and replied that he was only authorized to read the letter and furnish a copy if requested. The substance of its contents, it is presumed, may be gathered from Nos. 4 and 6, herewith transmitted. It was an attempt to make known to the Government of the United States privately in what manner it could make explanations, apparently voluntary, but really dictated by France, acceptable to her, and thus obtain payment of the 25,000,000 francs. No exception was taken to this mode of communication, which is often used to prepare the way for official intercourse, but the suggestions made in it were in their substance wholly inadmissible. Not being in the shape of an official communication to this Government, it did not admit of reply or official notice, nor could it safely be made the basis of any action by the Executive or the Legislature, and the Secretary of State did not think proper to ask a copy, because he could have no use for it. Copies of papers marked Nos. 9, 10, and 11 shew an attempt on the part of the French charge d’affaires to place a copy of this letter among the archives of this Government, which for obvious reasons was not allowed to be done; but the assurance before given was repeated, that any official communication which he might be authorized to make in the accustomed form would receive a prompt and just consideration. The indiscretion of this attempt was made more manifest by the subsequent avowal of the French charge d’affaires that the object was to bring this letter before Congress and the American people. If foreign agents, on a subject of disagreement between their government and this, wish to prefer an appeal to the American people, they will hereafter, it is hoped, better appreciate their own rights and the respect due to others than to attempt to use the Executive as the passive organ of their communications.
