167. Every officer, on becoming the thirtieth on the list of lieutenants, must be prepared to undergo the required examination. Any officer, after four years’ service, may apply for such examination at an earlier period.
168. Instructions will, from time to time, be issued to the general or other officer commanding districts or stations, to assemble a board, to consist of three officers, viz., a field officer (of the artillery, if possible), an officer of the staff, and a captain of artillery, or an officer of that corps who may already have passed the examination. Either the gunnery instructor or the fire-master should, when practicable, be selected for this duty. If it be impossible to obtain a staff officer, a captain of the line should be substituted; if a second officer of artillery cannot be had, an officer of engineers should be substituted; but either the president or one member must be of the artillery.
169. That portion of the examination which can be best replied to in writing will be conducted by means of questions prepared by the deputy adjutant-general of artillery, and forwarded to the general officer commanding the district. The vivâ voce and practical examination will be conducted by the board of officers, who will satisfy themselves that the officer under examination not only possesses the requisite knowledge himself, but that he is able to impart that knowledge in a clear and satisfactory manner.
170. The board will then forward, through the general officer, its report, together with the written answers, to the adjutant-general of the forces; and, in returning to him the written answers, the president of the board will certify that they are the bonâ fide performances of the candidates, without assistance. The written papers will then be examined by the deputy adjutant-general of artillery, and the result, together with the opinion of the board, reported to the Commander-in-Chief.
