By the Mail of this Morning, I had the honor of receiving your Letter of the 28th of March, covering one for Mr Warden—that Gentleman took his departure from this City for Washington, a day or two since, with a view, as I understand, to obtain a passage from that place to France, in the Vessel which is to carry Mr Barlow on his Mission: I have this day forwarded your letter to Mr W. by Post, to Washington; addressed to the care of Mr Munroe, which I hope will meet your Approbation.

The Map delineating the route of the projected Canal through the Western parts of this State, which I mentioned in my last letter, will not be compleated until the ensuing Week
