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

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

MathematicsSzSurveying HE.time spent on I Mathematics here is short. One semester is given to each of Mathe- matics 01 tFarm Arith- metici, Mathematics 02 tAlgebrai, Mathematics 03 tGeometryi ,Mathemat- ics 04 tComputation and Physics. Mathematics 05 tChain Surveying and Levelingi, and Mathemat- ics 06 tmore Leveling and Transit Surveyingi. The Farm Arithmetic is a brief review of frac- tions, decimals and per- centage and their applica- tions to simple farm prob- 1ems,such as figuring percentages of food ele- ments and various farm products, rations and nu- - tritive rations, soil moist- ure, standardization of milk and other creamery problems, field crop val- ues, and building mate- PROF. C. M. TITUS rials, etc. In Algebra the students study the fundamental operations and the solution of simple equations, special stress being put on the handling of such formulas as are used in farm machinery. 1n Geometry the definitions of the more common geometrical terms, fundamental principles taxioms, postulates, eth and the simpler and more practical theorems are taught, stress being laid on area theorems. The first half of Mathematics 04 is given to logarithmic computa- tions and the application of Algebra and Geometry to problems in land areas, figuring building materials and capacities of silos, tanks and reservoirs, hay stacks and concrete foundations, etc., and other problems which are not covered in Mathematics 01. The Physics part of the course deals with the principles of simple machines, mechanics of liquids as applied to pumps and siphons, work and power problems and the laws of motion and a very elementary treatment of electricity and 111agnetism leading up to the principle of the dynamo and motor. Mathematics 05 teaches the simplest methods of Chain surveying, including the measuring and mapping of irregular areas, and practice in profile and contour leveling and mapping such as are needed in laying out roadways and ditches and in checking land for irrigation. Mathematics 06 takes up cross-sectioning 0f ditches, roadways and problems 1n transit work, including the stadia method of topography. 18 k , h. -.A4,-G:.3,rt..d - -3...
