Memorandum:--

1. Hereafter, in all lecture halls, section rooms, and other meetings, members of the Reserve Officers' Training Corps will arise upon the entrance of the instructor and stand at "attention" until he directs them to be seated or until he has taken his seat.

2. At all formations in ranks, except when actually receiving instruction, cadets will be brought to "attention" by the officer or noncommissioned officer in charge upon the approach of a tactical instructor. The officer or noncommissioned officer in charge will then salute the instructor and give the command "rest" or "at ease" after the instructor has passed, or if he remains in the vicinity and so directs. The tactical instructors referred to herein are the Commandant and other commissioned officers of the Army, other commissioned officers attached to the Department of Military Science and Tactics, and the battalion commanders and their adjutants.

3. On all other occasions cadets, if in uniform, will come to "attention" upon the approach of a tactical instructor. If grouped together the cadet officer, non-commissioned officer, or private, as the case may be, will command "attention," and the senior will salute if covered (with headdress); if uncovered (with out headdress) he, like the rest, will simply stand at attention until the instructor has passed or has acknowledged the salute. In the case of individuals, not in a group, each will render the courtesy prescribed.

4. Cadet officers (captain and lieutenants) will be accorded the prescribed courtesies when in uniform. Noncommissioned officers (sergeants and corporals) are not saluted except as prescribed in paragraph 172, Infantry Drill Regulations, and when making reports to the sergeant-major or acting sergeant-major at ceremonies, such as guard mounting (paragraph 351, Manual of Interior Guard Duty, U. S. Army, 1914), or other formation where the noncommissioned officer receives reports for the officer in charge. All cadets, however, should stand at attention when addressed by or addressing a noncommissioned officer.

For rules governing salutes see "Honors and Salutes," paragraphs 758-765, Infantry Drill Regulations. Failure to observe these rules will not be excused on the ground of ignorance.

5. The President of Harvard University will receive all the courtesies for instructors.

6. The Governor of the Commonwealth National Guard and Reserve Officers, when in uniform, will be accorded the same honors and courtesies.

7. The attention of all cadets will be called to the fact that every official notice is duty posted upon the bulletin boards of the Department, in the basement of University Hall, south entrance; and that there is no excuse for cadets failing to inform themselves as to the current instructions, showing sections, lecture groups, companies or detachments to which they may be assigned or attached; the subject matter taught, or the outside reading, and special work required. Further information can be obtained at the Commandant's Office, 1 University Hall.

8. This memorandum will be published at the first assembly of each company immediately following its receipt, for the information and guidance of all concerned. C. CORDIER.   Captain, U. S. Army, Commandant.
