The efficiency of our manufacturing centers has resulted from the ease with which we are able to make use of electricity. High schools are putting to use an extensive course of study in elec- tricity and its uses. Shop projects begin with investigation of dry cells and magnetism, demonstrations of motor and generator principles and differences in opera- tion of direct and alternating currents. In studying uses of electricity, the student learns how to repair heating devices, extension cords, switchboard relays, sockets for small lamps, fuses, small motors, and metering equipment. A study of the fundamentals of electric power and its generation is taken up, including generators, motors, relays, transformers and the wiring, phasing, and testing of each piece of equipment. In the study of electrical communication systems, the boy studies the operation of the telegraph and telephone circuits. The study of telephone equipment takes up the design and construction of the receiver, transmitter, switch boards, induction cords, condensers, and installations. In the study of the telegraph principles the boys set up a circuit and make a telegraph set for experimental purposes. Time is given to the discussion of the working principles of such motor- ized appliances as electric refrigerators, air-conditioning, washing machines, electric fans, ironing machines, and their repair. Radio construction principles are included so that the boy may be more efficient in these operations. Insulating and connecting as well as theoretical principles of operation of all electrical equipment is taught. 15 • ARGENTIAN '44

• MECHANICAL DRAFTING • For an out-of-class project in mechanical drafting several boys in the drafting classes have constructed a miniature office building. The frame structure was structural steel type. The channel H and I beams were all constructed of paper, glued into their special forms. The outside walls and trim appeared in a stone finish which was produced by paint and brush. Some of the problems encountered in the construction were types of beams and braces, load strength, stairway, elevator shaft, wiring, plumbing, expansion, insulation, fire proofing and lighting all of which proved to be interesting problems for the builders. First year mechanical drafting includes blueprint reading, sketching and instrument drawing. Considerable time is given to reading drawings because far more perform the construction and manufacturing operations than do the drafting. The second year work continues with instrument drafting. Problems used are of a practical nature and selected from the field of general drafting. Work beyond the second year is more advanced. The problems selected are taken from the fields of machine and architectural drafting. The prob- lems gradually become more complex as they cover a wide range of expe- riences. Where possible, production drafting is encouraged. Students pursuing one of the shop courses often take the responsibility of providing their par- ticular shop with drawings and blueprints.

• OFFICE MACHINES • Office machines, an office training course, was installed to meet the growing demand for specialized and versatile skills to enable the high school graduate to find employment in business offices. The course offers instruction in duplicating letters and forms by means of the mimeograph, ditto and speedograph machines, operation of adding machines and filing. The mimeograph course includes training in cutting stencils by use of the typewriter and the mimeoscope, care and operation of the mimeograph machine and making copies. The ditto course includes: preparation of master copies, using ditto carbon, ink, ribbon and pencil, also experience in running copies on both ditto and speedograph machines. The adding machines course includes practice in addition of all com- binations of numbers, with special attention to most frequently used com- binations, also practice in subtraction, multiplication and division. Emphasis is on accuracy. The filing course includes a thorough study of the fundamentals of filing and indexing in alphabetic, numeric, triple check automatic, geo- graphic, subject and soundex methods of filing. Emphasis is placed on the fundamentals of filing generally used.
