(Received 4.40 p. m.)

Colonel D. H. RUCKER, Quartermaster:

Steamers are constantly arriving here loaded with troops. Some have orders to return to Fort Monroe, some to Yorktown, and others to Aquia Creek, and quite a number no orders at all. I should like to be instructed what disposition is to be made of those who are without orders.

Captain C. B.. FERGUSON,

Assistant Quartermaster, Alexandria:

Your telegram received. If any vessels arrive without any orders you had better send them back to Fort Monroe. If you have a middling sized steamer I wish you to send her to Sixth-street wharf to-morrow morning, as I wish to send troops across the river for the next two days. Please answer.
