GUARD DUTY IN THE TRENCHES.--It differs from guard duty as we are accustomed to it. The challenge is not "Who is there?" but rather a sudden and imperative "Hands up." The party challenged throws up his hands and gives the countersign in a low voice. Sentinels are posted in the front line and in the line of dugouts, one at each entrance to a dugout to give immediate warning. Watchers are posted at places having a good range of view; at night they keep watch over the parapets rather than through the loopholes since the latter afford only a narrow range of view. Auto riflemen (6 or 7 to a post) are used as watchers, one being on duty at a time. They should have a favorable background to provide concealment. [Illustration: Plate 14] [Illustration: Plate 14A.] CHAPTER 13. Company Administration. Company administration is a very broad subject and can be really learned only by experience. However, this chapter will attempt to point out a few suggestions and practices that may prove of some assistance, particularly to the new officer. We shall treat briefly of the first organization of the company; then we shall try to reproduce in some slight measure the actual work of a day in camp (more particularly of a training camp such as Plattsburg); then finally we shall treat of the orderly room and some of the problems that come up in army paper work. Notes on Organization. (By MAJOR W.H. WALDRON, Twenty-Ninth Infantry.) 1. PREPARE IN ADVANCE TO RECEIVE MEN ASSIGNED TO COMPANY. (a) Detail one of the Lieutenants in charge of the company mess. DUTIES.--Secure the necessary kitchen and dining room equipment and prepare everything to start the mess; make up a bill-of-fare for a week based on the ration components and supplies available; secure the rations and issue them to the cooks daily. Train a mess Sergeant in the duties that fall to him. In fine, this Lieutenant will have complete charge of the company mess, the cooking, and serving of the meals, training of cooks and men detailed for duty in connection with the mess. (b) Detail the other Lieutenant in charge of property. DUTIES.--Procure all the articles of individual and company equipment from the Regimental Supply Officer. Get into the company storeroom and prepare it for issue. Train the Company Supply Sergeant in the duties that will fall to him. (c) This leaves the Company Commander free to organize the orderly room and make the necessary preparations to receive the men as they report. IF IN CANTONMENT.--Lay out the quarters into platoon sections and subdivide these into squads, allowing space for platoon leaders and guides. Starting at the end of the quarters plainly mark each squad section, 8 beds, four on each side of the aisle with the number of the squad--first squad, second squad, etc.
