SECOND CORPS, June 20, 1862.
General J. G. BARNARD:
I cannot see any change in the work behind Garnett's house, nor any one at work on it to-day. A wooded raivne makes up behind Garnett's, and behind this shelters of a company can be seen in the ravine. There is probably a stronger force concealed here, and their noise may have given rise to the idea of work being done there. The rebels are still at work whese we saw them on the railroad a mile and a quarter in advance of Fair Oaks, just at the left of the railroad. I think this musth be the zigzag which I saw at the right of the line of rifle-pits when on Hooker's front the other day. From near this work the enemy shelled our camp this afternoon by putting a few pieces at the pine tree on the railroad and sending a man up the tree. This work can easily be shelled at any time, adn by firing a little to the south we cartainly should hit their camps. If this were done every time they shelled us they would probably soone cease ti, and it ought to be done at any rate. Enemy are still at work at Old Tavern chimney, and I saw one gun inside the work to-day.
