I have received your letter of Jany. 26. The work to which you have turned your thoughts is of a character which justly claims for it my favorable wishes. A Legislative History of our Country is of too much interest not to be, at some day, undertaken; and the longer it be postponed, the more difficult & deficient must the execution become. In the event of your engaging in it, I shall cheerfully contribute any suggestions in my power as to the sources from which materials may be drawn; but I am not aware at present of any not likely to occur to yourselves. Accept my friendly respects.
