write me, and send, in by mail messenger to-morrow, or by [Henry W.] Perkins, if I shall make any further exertions to have the city guards at Washington out down, and some portion sent to us. It is now 1. 15 a. m., and I shall tire you, if I write any more, as much as I have myself, but I wanted to give you full ideas of the condition of affairs. I send a few good maps by Perkins; will try and arrange about guides, spies, &c., with other things, to-morrow, or to-day, as it is now.

Very respectfully, your obedient servant.

Major-General, Chief of Staff.
