In the first letter, dated October 25, 1859, Mason is concerned about slaves and freed blacks in posession of guns in Fairfax County; he implores Washington to coordinate the seizure of these weapons using \"a good and efficient patrol - all of native born men\" raised specifically for the job.  In the second letter, dated November 2, 1859, Mason suggests forming a Volunteer Company in the wake of John Brown's raid, and he inquires whether Upton Herbert, the Superintendent of Mount Vernon, would be willing to take command of it."],"userestrict_html_tesm":["\u003cp\u003eThere are no restrictions on personal use.
