From Northwestern Virginia.
--Late news from the Northwestern portion of the State represents that the forces under Col. Wm. L. Jackson have recently made a rich haul upon the enemy at a point known as Bulltown, in Braxton county. Information reached Col. J. in the early part of last week that there was a large number of the enemy's wagons at that place, guarded by some three hundred men, who were left in charge of them, the main body of the enemy's forces in that section having been sent to reinforce Rosecrans. With the force at his disposal Col. Jackson pushed off to Bulltown, where he captured the whole Yankee guard and a large number of wagons, horses, and equipments. It is hoped that he has succeeded ere this in removing his plunder within our lines. Averill's force, or a portion of it, is still at Beverly, in Randolph county.
