JULY 3D.—Uncle Sam’s cashier has arrived at last, and we have been paid for two months’ service. The married men are quite anxious to send their money home to their wives and little ones. It is risky sending money North from here, yet, to some, more dangerous to keep it. I saw two boys sitting on a log, today, playing poker at five cents a game. Five cent currency is paid in a sheet, and, as either lost the game, a five cent piece was torn off.
