REPORT OF DEPARTMENT OP PHYSICS. 43 



One class, second term, elementary physics. Mechanical freshmen, five 

 clays per week. Study sound and light. The topics in sound were its 

 production, propagation, reflection and refraction, theory of music, 

 analysis of sound and migratory motion. In light, velocity, photometry, 

 reflection, refraction, dispersion, optical instruments, sources of light and 

 polarization; lecture table experiments and laboratory class in meas- 

 urements. 



Two classes, third term, elementary physics. Mechaniccl sophomores, 

 five days per week, and agricultural juniors, five days per week (first half). 

 Lectures and quizzes, first half: Heat, the dynamic theory, expansion, 

 vapor tension, latent heat, hygrometry and specific heat. Second half: 

 Magnetism, properties of magnets and processes of magnetization; elec- 

 tricity, its sources, the units of frictional machines, batteries, measure- 

 ment of voltage, resistance and current; inductive currents, magneto and 

 dynamo. As in preceding terms, the laboratory work is largely quantita- 

 tive and students become familiar with apparatus and methods. Through- 

 out the course in elementary physics, Atkinson's Ganot was used as a 

 reference book. 



One class in physics. Agricultural seniors, elective (number in class 

 twenty-three). Class room work five days per week, and laboratory work 

 five days per week. Subjects for both class and laboratory work were 

 sound, light, electricity and magnetism, following much the same outline 

 as given in elementary physics. 



One class in electrical engineering. Mechanical seniors. Text book, 

 Slingo and Brooker's Electrical Engineering. Five days per week, 

 also electrical laboratory work four days per week. Lecture table appar- 

 atus used when applicable. The laboratory work as follows: Construction 

 and calibration of a galvanometer adjustment of different elements and 

 determination of electromotive series. Finding current strength by plat- 

 ing, by decomposition of water, by calorimeter. Determination relative 

 values of horizontal and vertical components of earth's magnetism. 

 Operation Wheatstone's bridge, magnetos, telephones, converters and 

 accumulators. Determine characteristic of a series dynamo, a shunt 

 dynamo, and a compound dynamo. Determination of efiiciency of an 

 electric motor. 



Special class. Summer school. Laboratory practice ten hours per 

 week (one-half term), consisted in work with instruments of precision and 

 attainment of some knowledge of the methods of physical manipulation. 



The department has made much progress during the past year. Appar- 

 atus has been added to the laboratory equipment making it possible to 

 give a regular course of instruction in verification of physical formulae. 

 The new fifteen-horse power boiler and engine are of especial value in the 

 work in electrical engineering, besides affording opportunity to the stu- 

 dent to do experimental work for their graduating thesis. Experimental 

 work should form a large and important element in the education of the 

 young man who expects to follow any techinal line. This college should 

 furnish as fast as possible a well arranged and adequate equipment, well 

 up to the times, for the students' work in this department. The need for 

 this training is fully acknowledged through the business world. Even 

 now the well trained callege man may have difficulty in overcoming the 

 prejudices entertained by practical men. It is necessary the work done 

 here unite the practical with the theoretical, so as to enable our graduates
