No sooner are the contents of the mail-bag distributed, and devoured by the eager newsmongers, than active preparations are made for responding. Some men carry pocket-inkstands and write with pens, but the majority use pencils. Here you see one seated on a stump or fence, addressing his "sweet-heart" or somebody else; another writes standing up against a tree, while a third is lying flat on the ground. Thus either in the tents or in the open air, scribbling is going on, and the return mail will carry many sweet words to those who cannot be wholly forgotten. I suppose in this way we are not only making, but writing history. Camp-life then is not entirely monotonous. THE BUGLE-CORPS. Sights and sounds of interest may be seen and heard at almost every hour of the day. The morning is ushered in with the shrill reveille, which means awake and arise. This is well executed by our bugle-corps, which Captain Duffie has organized, and is drilling thoroughly. All our movements are now ordered by the bugle. By its blast we are called to our breakfast, dinner and supper. Roll-call is sounded twice a day, and the companies fall into line, when the first sergeants easily ascertain whether every man is at his post of duty. The bugle calls the sick, and sometimes those who feign to be, to the surgeon's quarters, and their wants and woes are attended to. By the bugle we are summoned to inspections, to camp-guard, to the feeding and watering of our horses and to drill. A peculiarly shrill call is that which brings all the first or orderly sergeants to the adjutant's quarters to receive any special order he may have to communicate. Thus call after call is sounded at intervals throughout the day, ending with "taps," which is the signal for blowing out the lights, and seeking the rest which night demands. CAMP GUARD. Our principal duties now are camp guard and drill, which we perform by turns. Every morning quite a large force is detailed, with a commissioned officer in command, for guard duty. These form a line of dismounted pickets, or vedettes, around the entire camp. They are stationed within sight and hailing distance of each other, enabling them to prevent any one from leaving or entering camp without a written pass in the day-time, or the countersign at night. The rule is to have each man stand post for two hours, when he is relieved. This is the maximum time, and is sometimes made less at the discretion of the commandant.
