 CmCULAE FOR THE INFORMATION OF PERSONS DESIRING TO ENTER 
 THE NAVY AS ACTING ENSIGNS FOR ENGINEERING DUTY. 
 
 An act of Congress approved August 29, 1916, authorizes the appointment of 30 
 acting ensigns, annually, as follows: 
 
 ' ' That the Secretary of the Navj^ is hereby authorized to appoint annually in the 
 line of the Navy for a period of ten years following the passage of this act, in the order 
 of merit determined by such competitive examination as he may prescribe, thirty 
 acting ensigns for the performance of engineering duties only. Persons so appointed 
 must have received a degree of mechanical or electrical engineer from a college or 
 university of high standing or be graduates of technical schools approved by the Sec- 
 retary of the Navy, must have been found physically qualified by a board of medical 
 officers of the Navy for the performance of the duties required, and must at the time 
 of appointment be not less than twenty nor more than twenty -six years of age. Such 
 appointments shall be for a probationary period of three years, and may be revoked 
 at any time by the Secretary of the Navy. 
 
 "Such acting ensigns shall, upon the completion of the probationary period of three 
 years, of which two years shall have been spent on board cruising vessels and one year 
 pursuing a course of instruction at the Naval Academy prescribed by the Secretary 
 of the Navy, be commissioned in the grade of lieutenant of the junior grade after sat- 
 isfactorily passing such examination as may be prescribed by the Secretary of the 
 Navy, and having been recommended for promotion by the examining board and 
 found physically qualified by a board of medical officers of the Navy. 
 
 "Such officers shall thereafter be required to perform engineering duties only, and 
 shall be eligible for advancement to the higher grades in the manner herein pro"\dded 
 for line officers assigned to engineering duty only." 
 
 APPOINTMENT. 
 
 A candidate for appointment as acting ensign for engineering duty must, at the 
 time of appointment, be a citizen of the United States, not less than 20 nor more than 
 26 years of age, a candidate who has passed his twenty-sixth birthday not being 
 eligible. Attention is particularly invited to the italicized portion of the preceding 
 sentence. Although a candidate may successfully pass the professional and physical 
 examination his appointment can not be made unless he i.s within the prescribed 
 age limit at the time he accepts an appointment that may be tendered by the depart- 
 ment after passing all examinations. The age limit is prescribed l)y law and the 
 Navy Department has no discretion in the matter of wai^ving same. 
 
 Therefore, no person will be permitted to appear who will pass his twenty-sixth 
 birthday within two months after the date set for the examination. This is done in 
 order to prevent candidates from going to the trouble and expense of appearing for 
 examination when it is certain that they can not be examined, ha^•e their papers 
 marked by the local board in Washington, and their appointments issued and accepted 
 before reaching the statutory age limit of 26.

 promptly acknowledged, and if the candidate is considered eligible a permit will be 
 issued in time to enable him to appear for the professional examination. 
 
 PROFESSIONAL EXAMINATION. 
 
 The professional examination of candidates will be held simultaneously tloroughout 
 the United States, after which all papers will be forwarded to the local board at Wash- , 
 ington, D. C, for marking. When this has been done permits will be issued to the 
 successful candidates authorizing them to appear for the physical examination. 
 
 Candidates should promptly advise the Bureau of Navigation of any change of 
 address in order that permits, if issued, may reach them promptly-.
