ARTICLE SECOND.- Instruction of the Battalion.

42. Every commanding officer is responsible for the instruction of  his command.  He will assemble the officers together for theoretical and practical instruction as often as he may judge necessary, and when unable to attend to this duty in person, it will be discharged by the officer next in rank.
43. Captains will be held responsible for the theoretical and practical instruction of their non-commissioned officers, and the adjutant for the instruction of the non -commissioned staff. To this end, they will require these tactics to be studied and recited lesson by lesson; and when instruction is given on the ground , each non -commissioned officer, as he explains a movement, should be required to put it into practical operation.
44. The non-commissioned officers should also be practiced in giving commands. Each command, in a lesson at the theoretical instruction, should first be given by the instructor, and then repeated in succession, by the non-commissioned officers, so that while they become habituated to the commands, uniformity may be established in the manner of giving them.
45. In the school of the soldier, the company officers will be the instructors of the squads; but if there be not a sufficient number of company officers present, intelligent sergeants may be substituted; and two or three squads, under sergeant instructors, be superintended, at the same time, by an officer.
46. In the school of the company, the lieutenant-colonel and the major, under the colonel, will be the principal instructors, substituting frequently the captain of the company, and sometimes one of the lieutenants; the substitute, as far as practicable, being one of the principals.
47. In the school of the battalion, the brigadier general may- constitute himself the principal instructor, frequently substituting the colonel of the battalion, sometimes the lieutenant colonel or major, and twice or thrice, in the same course of instruction, each of the three senior captains. In this school, also, the substitute will always, if practicable, be superintended by, the brigadier general or the colonel, or (in case of a captain being the instructor), by the lieutenant colonel or major.
48. individual instruction being the basis of the instruction of companies, on which that of the regiment depends, and the first principles having the greatest influence upon this individual in ion, classes of recruits should be watched with the greatest care.
49. Instructors will explain, in a few clear and precise words, the movement to be executed; and not to overburden the memory of the men, they will always use the same terms to explain the same principles.
50. They should often join example to precedent, should keep up the attention of the men by an animated tone, and pass rapidly from one movement to another, as soon as that which they command has been executed in a satisfactory manner.
51. The saber bayonet should only be fixed when required to be used, either for attack or defense; the exercises and manœuvres will be executed without the bayonet.
52. In the movements which require the bayonet to be fixed, the chief of the battalion will cause the signal to fix bayonet to be sounded; at this signal the men will fix bayonets without command, and immediately replace their pieces in the position they were before the signal.

INSTRUCTION OF OFFICERS.

53. The instruction of officers can be perfected only by joining theory to practice. The colonel will often practice them in marching and in estimating distances, and be will carefully endeavor to cause them to take steps equal in length and swiftness. They will also be exercised in the double quick step.
54. The instruction of officers will include all the Titles in this system of drill, and such regulations as prescribe their duties in peace and war.
55. Every officer will make himself perfectly acquainted with the bugle signals; and should, by practice, be enabled, if necessary, to sound them. This knowledge, so necessary in general instruction, becomes of vital importance on actual service in the field.

INSTRUCTION OF SERGEANTS.

56. As the discipline and efficiency of a company materially depend on the conduct and character of its sergeants, they should be selected with care, and properly instructed in all the duties appertaining to their rank.
57. Their theoretical instruction should include the School of the Soldier, the School of the Company, and the Drill for Skirmishers. They should likewise know all the details of service, and the regulations prescribing their duties in garrison and in campaign.
58. The captain selects from the corporals in his company those whom he judges fit to be admitted to the theoretical instruction of the sergeants.

INSTRUCTION OF CORPORALS.

59. Their theoretical instruction should include the School of the Soldier, and such regulations as prescribe their duties in garrison and in campaign.
60. The captain selects from his company a few privates, who may be admitted to the theoretical instruction of the corporals.
61. As the instruction of sergeants and corporals is intended principally to qualify them for the instruction of the privates, they should be taught not only to execute, but to explain intelligibly everything they may be required to teach.

COMMANDS.

There are three kinds.
62. The command of caution, which is attention.
63. The preparatory command, which indicates the movement which is to be executed.
64. The command of execution, such as march or halt, or, in the manual of arms, the part of command which causes an execution.
65. The tone of the command should be animated, distinct, and of a loudness proportioned to the number of men under instruction.
66. The command attention is pronounced at the top of the voice, dwelling on the last syllable.
67. The command of execution will be pronounced in a tone firm and brief.
68. The commands of caution and the preparatory commands are herein distinguished by italics, those of execution by CAPITALS.
69. Those preparatory commands which, from their length, are difficult to be pronounced at once, must be divided into two or three parts, with an ascending progression in the tone of command, but always in such a manner that the tone of execution may be more energetic and elevated: the divisions are indicated by a hyphen. The parts of commands which are placed in a parenthesis, are not pronounced.
