August 3, 1861.—Called on James T. Jackson, a Secessionist, for a map of Virginia—one of the Board of Public Works maps. He said he once had one but his brother had sold it to a captain in [the] Seventh Regiment. Called then on William E. Arnold, a lawyer and Union man. He offered every facility for getting information and gave such as he could; also lent us a good map. Hottest day yet. Dr. Joe ailing. Young Jewett doing well, but getting tired and sore.
