INTRODUCTION. THE following Questions embrace all that any engineer would be likely to be asked when un dergoing an examination, but, of course, not onequarter of them will ever be asked at any one examination; nevertheless, as the examiners have the right to vary the questions, it may be advisable for the candidate to make himself conversant with them all. Moreover, supervisors, when examining men for licenses as engineers in the mercantile marine, ask the same questions that the board of examiners for the United States revenue service do, and vice versâ, while engineers applying for certificates to take charge of stationary steam-engines are, in many instances, asked similar questions. In regard to this latter class, the inquiry is generally directed to ascertain their knowledge of steam-boilers and skill in their care and management. iii |
