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...

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

. N o !NN 7.? - , KN N , .mmxmtxxximxxxxwmmx WWMWWW Division of Agronomy HE leading activities of this Division are teaching and re- search. The principal Extension activity con- sists in the production and distribution of pure seed. This season this Division has distributed throughout the State over eight hundred sacks of barley, wheat and oat seed. Applications have exceeded many times this amount, but in order to accomplish the greatest good the allotments were limited and preference given applicants who would plant on clean fal- low and agree to dispose of the crop for seed. One of the greatest steps for- ward in the development of a new grain sorghum has been accomplished by this Division. This va- riety is known as Yolo White. In tests it has PROF- 5- W- HENDRV proven to be more productive than Milo or other grain sorghums, but its greatest feature is its dwarf nature, uniformity and erect head, qualities which are adapted to machine heading. These qualities no doubt will stimulate the production of grain sorghum in California. Seed for several thousand acres have already been distributed. Sunflowers 0f the mammoth western variety were grown last season as a silage crop for the first time at the University Farm, and feeding tests with dairy cows are now under way. The sunflowers yielded from twenty to twenty-four tons green weight per acre. The sunflowers grew to a height of from ten to eleven feet, but were so coarse and woody that it was necessary to cut each stock separately by hand. They are hardier than sorghum, and may be profitably grown On poor soils and mountain elevations or in cool coast climates where sorghums cannot be grown. An elaborate series of cobperative experiments with the Bureau of Plant Industry, U. S. D. A., on cereal diseases is now in the third year of progress. All of the cereal investigational work of the U. S. D. A. has been transferred to Davis, and an elaborate cereal nursery planted. Provision has been made for a new seed cleaning plant, and modern seed cleaning machines will be installed. This will enable the Division to maintain and carry out a more effective program of building up and maintaining to a high standard the seed stocks of the State. 19
