"(2) When an officer entitled to the salute passes in rear of a body of troops it is brought to attention while he is opposite the post of the commander.

"(3) In public conveyances, such as railway trains and street cars, and in public places, such as theatres, honors and personal salutes may be omitted when palpably inappropriate or apt to disturb or annoy civilians present. (C. A. R. No 50, Jan 8, 1917).

4. Cadet officers (captains and lieutenants) will be accorded the prescribed courtesies when in uniform. Noncommissioned officers (sergeant 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 prescribed for instructors.

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

7. The attention of all cadets will be called to the fact that every official notice is duly 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.
