I propose to leave this tomorrow for Monticello. the critical state of things rendering it necessary that I should recieve daily information both from the North & South, the Postmaster General has established a rider from Fredericksburg to Monticello during my being there for every day of the week except that on which your mailstage goes. permit me to rely on your forwarding by that rider whatever packages come for me from any quarter, and to distribute in like manner what I shall send by that rider. I salute you with esteem.
