Reports from Washington.
Junction, Aug. 7th.
--I have just seen a gentleman from Washington city last Saturday.
He states that Meade's army, it is thought to receiving no reinforcements, as yet except some few negro regiments, whiles many regiments of his command, whose term has expired, are going home.
He says a large force is concentrating at Fortress Monroe to operate against Charleston.
He thinks that Grant a army will next attack Mobile.
He represents things quiet in the North, and expresses the opinion that the draft will be gently, but surely enforced.
Meade's army is supposed not to be as strong as Hooker's at Fredericksburg.
