During October the several classes receive practical instruction as follows: The first class in military engineering, the manner of making and recording the details of a military reconnoissance, and field sketching; the second class in siege and sea-coast artillery, and military signalling and telegraphy. The class is divided into two parts, composed of the odd and even numbers, which attend drills on alternate days--that is, artillery one day and signalling the next; the third class in light or field artillery, and the theory and principles of "target practice." Sometimes this latter is given during camp, as is most convenient. Sometimes, also, they receive instruction in ordnance. This, however, is generally deferred till they become first-classmen. For further instruction of the first class the following part of the personnel of a light battery is detailed from that class, viz.: three chiefs of platoon, one chief of caissons, one guidon, and six chiefs of section. Each member of the class is detailed for each of these offices in his proper order. The fourth class receives instruction in field artillery at the "foot batteries." This instruction is limited to the nomenclature and manual of the piece. Here, also, to assist the instructor, a chief of piece for each piece is detailed. They are required to correct all errors made by the plebes, and sometimes even to drill them. Hence a knowledge of tactics is indispensable, and the means of fixing such knowledge in the mind is afforded. Sometimes also two first-classmen are required to assist at the siege or sea-coast batteries. Every day throughout the year a guard is mounted. It consists of two officers of the guard--sometimes only one--one sergeant, three corporals--or more-- and twenty-four privates--sometimes, also, eighteen or twenty-one in camp, and twenty-seven in barracks. Every day, also, there is one officer of the day detailed from the first class. The weather permitting, we have "dress parade" daily. When unfavorable, on account of snow, rain, or severe cold, we have "undress parade"--that is, parade without arms and in undress or fatigue uniform, the object being to get us all together to publish the orders, etc., for the morrow. After November 1st we usually have "undress parade," and then "supper mess parade." Between these two ceremonies the cadets amuse themselves at the gymnasium, dancing or skating, or "spooneying," or at the library; generally, I think--the upper classmen at any rate--at the library. After supper we have recreation and then study. And thus we "live and do" till January.
