The Packet brought me by the mail of friday from Milton, was strangely delayed somewhere; more than by the mistake which carried it to Monticello. It contained the inclosed letter from Pinkney, which has a much better flavour that his preceeding one of the 22d. June. Should any future packets or letters from the office of State, get to Monticello in the first instance, I beg you to open them. In some cases it may be of real importance to do so. Yrs. with respectful attacht.
