Artillery Camp.
--We made a visit yesterday to the Artillery Camp, on the College Grounds, near this city, and found everything in excellent order and the troops in a fine state of discipline. Col. Magruder is now in charge, and this fact is sufficient to ensure the organization of one of the best regiments of artillery that ever took the field. In Capt. Randolph's Howitzer Battery, and Capts. Cabell and Latham's Field Batteries, we have the material for service, and there is no lack of competent officers for instruction.
