axis 0 - 2 . NMVWMW. WWWWWW Agriculture Engineering HE California farmer uses more mechanic- al power per acre of improved land than any other farmer in the world. Many of his everyday jobs are engineering in na- ture. He operates and keeps in repair 35,000 electric motors, 24,000 gas tractors, almost countless stationary gas engines and a large per cent of the automobiles and trucks in this State. The Agricultural En- gineering Division offers instruction in the opera.- tion and maintenance of this farm equipment, to- gether With work in the construction and plan- ning of farm buildings. During this year 577 students have enrolled in the sixteen regular cours- es offered by this Divi- sion. These courses in- clude b1acksmithing,dairy PROF- '-- J- FLETCHER mechanics, gas engines, tractors,1nachinery,farni structures and buildings. Three laboratory buildings, totaling over 18,000 square feet of floor space, house the equipment of the Agricultural Engineering Division. Manufacturers and jobbers in this State have loaned over $40,000 worth of machinery to be used for instructional purposes. This equipment includes 15 gas tractors, 14 stationary gas engines, various types of plows, harrows, mowers, drills, pumps, etc. A steam boiler and accessories, feed pump and engine are available for the dairy mechanics work. The blacksmith shop contains 24 forges and other usual forging equipment. The work in farm structures includes the planning of buildings, estimat- ing of costs and lists of materials, concrete work and the construction of farm appliances and buildings. One of the-features of the divisional work has been the offering of gas tractor short courses. Ten such courses have been offered from 1916 to 1921, With a total enrollment of 1358 students. In 1921 a series of fourteen Tractor Extension Schools were planned to be held at various parts of the State. To date six of these schools have been conducted With a total enrollment of 346 students. , Extension work of the division consists mainly of the preparation of plans of farm structures. These include plans of such buildings as poultry houses, milking barns, dipping vats, hay storage barns, etc. 15

Dairy Industry PPLICATION of sci- entific principles to the manufacture of dairy products is now es- sential t0 the largest suc- cess in dairy manage- ment. The Dairy Indus: try Division gives instljuc- tion in principles of dalry- ing, market milk, Cheese making, butter and Ice cream making, dairy plant management and creamery practice. Rec- ommended subjects given in other divisions are Milk Production, Judging of Dairy Cattle, Diseases of Animals, and Dairy Mechanics. After students have had some experi- ence in commercial plants, instruction in these cours- es should aid them in be- coming successful em- ployees of owners of dairy manufacturing plants. A commercial cream- ery is operated through- out the year, for the purpose of teaching students and carrying 011 inves- tigational work in the manufacture of dairy products. The sale of dairy products during the past year has amounted to $93,000. The daily manufacture of these products gives excellent facili- ties for practice in each department, and during the year there has been 441 enrollments of students in the various courses. A new Dairy Industry building is now under construction at the University Farm, which will give complete facilities for all phases of teaching and investigation, in connection With butter, cheese, ice cream, market milk, and condensed milk. The first floor of the main building Will include laboratories for butter and market milk, commercial testing, student testing, and bacteri- ology; a salesroom, offices and student locker-room. The second floor will be occupied by three lecture rooms, seminary, reading and dairy products judging rooms, office and storage space. The manufacturing Wing Will house the largecreamery laboratory, which will be used for teaching advanced students and those electing practice work in butter, cheese, ice cream, market milk, and milk con- densmg. There Will be also the milk receiving department, a student cheese laboratory, refrigerating, icemaking; storage and machinery rooms. DR. C. L. ROADHOUSE 14

O.'N12 a Division ofVete rinary HE activities during I the past year, on the part of the Divis10n of Veterinary Science lo- cated at Davis, have fol- lowed the same general plan as that of previous years. In the Fall semes- ter about 70 Farm School students and 40 Univers1- ty students were given in- struction intended to as- sist them as livestock men in preventing destructive animaldiseases. This Spring semester 34 Uni- versity students are re- ceiving additional in- struction of this charac- ter. The large number of Classes and breeds of live- stock on the University Farm offers to the Divi- sion opportunities to dem- onstrate to the student, not only some of the com- mon diseases which he . will encounter as a live- DR. 5- M- HAYES stock breeder, but also principles and practices useful in the treatment and prevention of disease. In addition to these activities the members of the Division reply to many letters of inquiry relative to animal diseases, receive tissues of dead animals for laboratory diagnosis, confer with Visitors seeking infor- mation upon the treatment of sick animals, make some field investiga- tions of outbreaks of disease, and engage in research. The chief problems upon which research has been conducted during the past two years are those of infectious abortion in swine and cattle. Members of this division were among the first to isolate the causative germ and to determine and publish other important facts of this infec- tion in hogs. This will now be the major research activity as long as money is available and the information obtained justifies. During the Christmas vacation the Division held a five-day short course for veterinary practitioners of the State. The course specialized in diseases of cattle, but diseases of other animals received attention. Prominent veterinarians from other States were on the progam. Eighty- five veterinarians attended the course. Since last August, Dr. Robert J ay, field veterinarian for the United States Bureau of Anlmal Industry, has been stationed With the Veterinary gezlilgrclhat Dayis. Dr. J ay will make field investigations of hog diseases t arge, In an effort to reduce losses from these dlseases. 16 DiviS
