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

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

X wamsmm h kwamm ......... Division of Irrigation HIS Division was one of the first to start investigational work on the University Farm. In 1908 the twenty-five acres now occupied by this Division were leveled and experimental work started. This work dealt principally With the duty of water and water re- quirements of alfalfa, small grains and other field crops, and has been actively continued until the present time. Beginning in theSum- mer of 1922 this experi- mental work is to be eX- tended to the twenty-six acres now known as Field N0. 7. This area is to be leveled and equipped With a complete concrete pipe system. A long time project is being planned covering an exact study of the econOmical use of water in the irrigation of PROF- 5- H- BECKETT Indian Corn, Dwarf Milo, Beans, Sudan Grass and Hemp. To each of these crops varying quantities of irrigation water are to be applied at varying stages of development of the crop, comparison being made of the yields obtained from the different irrigation treatments. Direct delivery of water will be made to every plot under investigation, and an accurate meter measurement kept. With the coming of University Freshmen t0 the University Farm in the Fall of 1922, additional courses in.Irrigati0n Practice are being offered. These courses will substitute for those heretofore offered to the Freshmen and Sophomores at Berkeley. As a part of laboratory equipment for giving these courses, a field laboratory containing all standard irrigation equipment has been installed. This covers all types of devices, such as gates, valves, delivery boxes, tapoons, etc., used both in concrete pipe and open ditch systems for the irrigation of alfalfa, field- crops and orchards. Additional devices have also been added to the field laboratory of water measuring devices Which greatly facilitates the demonstration and instructional work in the measurement. of irrigation water. These field laboratories contain the most complete assortment of equipment and devices that has been assembled for instruction and demonstration purposes. 17
