_From a letter of the 29th of June._--That the accession of the State of Maryland to the general confederation, in the opinion of the Court of France, presents very great advantages; among which is this, that Congress having at last acquired that power, which the act of confederation has assigned them, it is to be expected, that their orders will be fully and exactly executed, and that they will take advantage of the resources of their country, to give to American patriotism new energy. The Minister is directed to inform Congress of the satisfaction the King has received on that account, and to tell them at the same time, that there is the most pressing necessity to take more effectual measures than heretofore to drive the British out of this continent. It is thought needless to enter into details about the circumstances, which render this measure necessary. The King entreats the United States, as his friends, not to lose a moment in acting as vigorously as possible against the common enemy. That Congress cannot be particularly acquainted with the different burdens, which France has upon her hands. She wishes to be in a situation to continue as effectual assistance to the United States as at this moment; but future events may happen in a manner different from what we may expect, though nothing can change her unalterable resolution to support the independence of her ally. The Count de Vergennes observes, that he shall not speak any more of the non arrival of the second division, having reason to believe from orders given to Count de Grasse, that the delay will be judged of greater utility to the United States, than if the announced reinforcement had been sent in the time expected. He adds, that the Chevalier de la Luzerne had been already informed of the causes, which had prevented a compliance with the expectation, which he had been authorised to give. _From a letter of the 11th of May._--That the Count de Vergennes had been informed by the Duc de la Vauguyon, Ambassador to the United Provinces, of the intention of Mr Adams to display his character as a Minister of the United States in Holland. That the Duke gave him no assistance on that occasion, knowing the application would have no favorable issue. The Chevalier de la Luzerne is directed to inform confidentially a committee, or Congress themselves, of these circumstances, in order, that they may transmit to their said Minister Plenipotentiary such instructions as they may think proper. France is too much interested in the fate of the United States not to give them such counsels as would have for a principal object their advantage and their dignity. * * * * * At a second conference, on the 24th of September, the following additional communications were made by the French Minister to the committee.
