The Negro troops.
--A visit to the rendezvous for colored troops, under the supervision of Majors Turner and Pegram, yesterday afternoon, showed a healthy progress of the cause, and demonstrated the entire feasibility of the scheme. In the large building known as Smith's factory we found a number of colored volunteers, each of whom seemed as happy as larks, and expressed their determination to fight the Yankees to the last. By the direction of Majors Turner and Pegram, these troops have been placed under the drilling management of Lieutenant Virginius Bossieux, and manifest, so far, great proficiency in the art (military manual of arms). As soon as proper equipments can be obtained, it is the purpose of the commanding officers to order a public parade of the troops on the Capitol Square.
