This will be handed you by Colo. Blackden, heretofore an officer in the American army and at present engaged in trade. He passes by the way of Rouen with a view to collect some information relative to the commerce which may be carried on between the United States and that part of France. He is a man of merit and as such I take the liberty of introducing him to your acquaintance. If you can be useful to him in procuring the information he desires, I shall be obliged to you. I have the honor to be Sir, your most obedient & most humble servant,
