The board of examiners is composed of the director of the school as president; a lieutenant-commander for German, English, and official duties; a constructing engineer for engineering, mechanics, and draw. ing; and two instructors at the Naval School, one of them for mathematics, the other for physics and chemistry. In the classification of subjects, engineering, mathematics, mechanics, and physics are in the first class; chemistry, drawing, and German in the second ; and Eng. lish and official duties in the third. The number of papers set is eightten, of which one is in German; two each in mechanics, physics, chemistry, and official duties; three in engineering, two of them descriptive, and one of calculations; and six in mathematics, two in arithmetic and algebra, two in geometry, and the others in trigonometry and stereometry. In drawing the board may either pass upon the work already performed or allow a certain time in the examination for a new drawing.

9.--OFFICIAL DUTIES: 1 lesson.
Naval and military organization; dispatches and reports; official relations between
executive officers and engineers (Dienstverhältnisse der Offiziere und Maschinen-Ingenieure).
Of the above subjects, engineering only belongs to the first class, German and English to the second, and French to the third. There is no examination in mathematics, chemistry, or official duties; and the remaining branches, mechanics and physics, are joined in the examination with engineering, In engineering and German 55 per cent, is required in each subject in order to pass.
The object of the examination at the close of the course of the engi. neer class is to test the proficiency of candidates for promotion to the grade of assistant mechanical engineer (Maschinen-unter-Ingenieur), the lowest commissioned rank in this branch of the service. The board is composed of the director of the school, the director of engine construction at the dockyard, or his deputy, as examiner in engineering, and the instructor in languages at the Naval Academy as examiner in German, English, and French.
The Commander-in-Chief of the station is required to attend the oral examinations and to sign the report embodying the result. In the examination in engineering three extensive papers are given, two of which are descriptive in their character, and the third dealing exclusirely with calculations. The oral examination is chiefly upon the construction and use of economical engines. In German an essay is prepared. In English and French the examination is both oral and written, and calls for a high standard of proficiency in reading, translation, and conversation, especially in English.
The object of this class or school is to give to applicants for appointment as naval paymasters, the necessary preliminary training for their profession. For convenience of organization it is made a part of the machinists' and pilotage school, and it has the same direction and gov. ernment. The instructors are naval officers, intendants, and paymasters. They are detailed for this service, in addition to their other duties, by the Commander-in-Chief at Kiel, on recommendation of the director of the school; and they receive extra pay according to the work they perform.
The paymaster applicants are ordered to attendance at the school by the Commander-in-Chief at Kiel. If they belong to the division of the North Sea, their orders are issued upon an understanding between the commanding officers at Kiel and Wilhelmshafen. They may perform regular duty at Kiel while pursuing their studies in the school, and they haveaccordingly to maintain official relations not only with the school director, but also with the commander of the naval battalion, and the intendant or the commander of the naval division, according to their assignment.
The course lasts from October 1 to March 31, and the studies are so arranged as not to interfere with the regular duties of the students. The studies comprised in the course are as follows; 1. Laws of exchange and commercial law: 2 hours a week. 2. Currencies, merchandise, and mercantile affairs: 2 hours.
Official duties: 1 hour.
English: 4 hours. 3. French : 2 hours. 6. Other modern languages or stenography: 1 hour.
All the duties are obligatory except the last, which is purely optional; but the programme is subject to such minor moditications as the director and instructors may judge necessary.
At the close of the course, examinations, both oral and written, are held in all the subjects. Certificates of graduation are given to the students, signed by the director and all the instructors, stating the acquirements, conduct, and application of the students. In case of fail. ure, the student may be recommended for a second trial of the course; and the final decision as to this recommendation rests with the Com. mander-in-Chief of the station.
