E.Electrical Engineering 1 2 Artisan Courses GENERAL INFORMATION What Artisan Courses are Offered.—The artisan courses herein described are a part of the work given during the summer at the University. They are arranged in two groups. The first group consists of courses in Electrical Engineering, Engineering Drawing, Industrial Arts, and Mechanical Engineering; the second group, of nine courses in the various lines of shopwork. Other Courses—Other courses are offered of the character usually taught in a first-class high school, as follows: algebra, geometry, chemistry, physics, free-hand drawing, and the English language. These will be valuable to all who have not had such studies. They may be taken together with artisan courses. For information concerning these, address the University Editor for Summer Term Bulletin. When They are Given—The artisan courses are given six days a week, as follows: First Group, from June 21 to July 17,1909; Second Group, from July 19 to August 13, 1909. Who Should Take Them—The courses will be helpful to the following persons: (a) Those who already have a trade or part of one and who desire to get some theoretical training and practical work in the drawing rooms, laboratories, and shops; as stationary, locomotive, and erecting engineers, oilers, firemen, custodians of large buildings, boiler makers, engine builders, foremen, superintendents, machinists, draftsmen, designers, skilled artisans and mechanics, electricians, switch-board attendants, wiremen, electrical linemen and repairmen, salesmen in mechanical and electrical lines. (b) Those who desire to hold positions similar to those above mentioned, but who now find it impossible to obtain an opportunity to serve an apprenticeship. (c) Those who have obtained a fair knowledge of the theory of a subject from correspondence courses or reading and who now need personal instruction and practice in it, such as may be obtained in the laboratories and shops. Employers Benefited—Proprietors of engineering and manu¬ facturing establishments can benefit themselves by sending certain of their employees to the University to take two or more of these courses, with the expectation that when they return after four or eight weeks of study and laboratory or shop practice they will be more capable and valuable men. Such has been the experience of employers who have tried it. Artisan Courses 8 Certificates of Work Done —No university credit or diploma will be given for artisan courses; but when requested, a certificate will be given to the student by the Dean, stating the courses that he has pursued satisfactorily. How to Gain Admission. —No examinations will be required of those applying for admission to these courses. One should be able to read and write and should have a working knowledge of arith¬ metic for any course. For some courses one or more years of practical experience is quite desirable. Persons should be preferably over eighteen years of age. In making application for admission, information on the follow¬ ing items should be given in considerable detail: 1. Age. 2. Amount of grammar school, of high school, of correspond¬ ence school, of collegiate training received. 3. Amount and kind of experience in practical work. 4. Courses of study by subject, and by letter or number, that the applicant desires to take. Selection of Work. —One should be careful to select only such courses as he is confident he can carry—an elementary rather than a too advanced course. It will be found wise to select one three-hour course in laboratory, shop, or drawing for each one hour of daily recitation. A total of three courses, or in special cases four, should not be exceeded. The hours assigned to the courses should be noticed so as to avoid conflict in time. When a selection has been made, it should be submitted in writing to the Dean as early as possible, so that the number in each course may be known. Early applicants will be given the preference. How to Register —All students are urged to register on the days set apart for that purpose, at the Registrar’s Office, University Hall, west end of the first floor. For the first four weeks, register on Monday, June 21, and for the second four weeks, on Monday, July 19, 1909. It is extremely important to the student that he should be present on the opening day. Tuition and Fees —Tuition is free. A registration fee of six dollars is charged each person, whether one or more courses be taken. One registration fee is sufficient for both four weeks. This fee must be paid before attendance at classes begins, and cannot be refunded except in case of extended sickness or unforeseen calamity before the middle of the term. No other charges will be made ex¬ cept for materials used in the shops and chemical laboratory, and for a gymnasium locker, if desired. Rooms and Board. —Board and lodging can be obtained near the University. Rooms accommodating two persons may be had 4 Artisan Courses at prices ranging from $8 to $12 a month. Rooms with board will cost from $4 to $6 a week. It is quite possible to cover all expenses, including books, but not including transportation, in the artisan courses of one group for $30, and of both groups, eight weeks, for $50. To Whom to Write.—For further information concerning rooms, board, registration, or admission address the Secretary, Professor George D. Hubbard, Ohio State University, Columbus, Ohio. COURSES OFFERED ELECTRICAL ENGINEERING Each course will run six mornings of the week, from June 21 to July 17. The laboratory work will illustrate and enforce the w""rk given in the class-room.
