I find among my collection of documents in relation to our foreign trade a book full of tables, statements, and representations, which tho written under a very different state of things from that now existing, must be of considerable use in estimating our prospects. I have the pleasure to send it by the mail, of Monday the 4th. Jany. & I retain this letter one day that it may serve as an advice. It appears to me highly advisable that a part of the library fund should be applied to the importation of such publications, if there is no other. Our ministers, consuls, officers of the customs &ca. have many opportunities to collect such valuable materials and are frequently able to give the best information and opinions upon such commercial affairs as they are daily led to ⟨witn⟩ess and consider. Our comml. system engages much attention. I am, Sir, yr. respectful hble Servt.
