The unusual amount of rainfall, making for favorable planting of ornamental material, has prompted the setting out of a large number of ornamental trees and shrubs. The selection of varieties has been made by Professor J. W. Gregg of the Division of Landscape Gardening at Berkeley, according to a systematic plan. The maintenance of this material will involve a constant expense for water and cultivation until the trees get large, when little will be required.

Infirmary.-A total of 173 cases have been handled in the Farm School Infirmary, which were: Abscesses 4, boils 18, sprains 12, felon, 1. tuberculosis 1, carbolic poison 1, influenza 7, coryza 18, headaches 16, acne 7, ringworms 5, varicocele operation 1, catarrh (nasal) 3, tonsilitis. (acute) 7, infected wounds 20, punctured wounds 15, fractures lower leg 2, plaster casts 3, fractured toes 2, fractured fingers 3, finger amputation 1, ingrowing toe nails 2, warts and corns 6, periostitis bone of foot 1, acute bronchitis 8, antityphoid vaccination 2, acute pharyngitis 2, chilblains 2, pneumonia 3.

In addition to the usual run of minor ills, the infirmary was called on to care for one case of pneumonia involving the employment of an extra night nurse.

For the first time, every student was required to submit to a physical examination at the opening of the school year. Fortunately, it was not necessary to reject any as physically unfit. Examination of the eyes and ears showed an unusual freedom from serious defect. Examination of the eyes by Dr. Milton H. Schutz showed 99 of 159 students suffering from errors of refraction. About two-thirds of

these have been properly corrected; the remainder were advised to give their eyes the necessary attention to correct this condition. Seventy-eight had more or less nasal defects, some of which are undoubtedly affecting their ability to study.

Library. The library has received 163 new books by purchase, and 65 by gifts, 27 of which were donated by a student, Mr. C. A. Halsey. The total number of books in the library is 2.169, of which 560 are herd books, shelved at the Animal Husbandry Division. Some 950 bulletins have been received during the year. Eighty-seven periodicals are received regularly, 38 of which are gifts.

The library is a distributing station for the Yolo County Free Library. About 100 books of fiction have been handled through this co-operative arrangement between the County and State library. Any books in the State Library have been available upon request through this arrangement.

Gifts.-The University Farm has received the following gifts during the past year in addition to those enumerated in the reports of Animal Husbandry, Dairy Industry, Farm Mechanics and Poultry Husbandry, and in addition to numerous loans.

CITRUS EXPERIMENT STATION

BY

H. J. WEBBER

In the Citrus Experiment Station the year has in large measure been one of reorganization. The new plans for the enlargement of the Station necessitated the employment of new men, purchase of equipment and development of plans for the extension of the investigations. This work of reorganization is still in progress and cannot be completed until the new Experiment Station farm and buildings are ready for occupation. It has been necessary to maintain the work started at the old Citrus Experiment Station at Riverside, which has served as temporary headquarters for the Station and at the Pathological Laboratory in Whittier, a part of the force being maintained in each place. The maintenance of the force in separate places and the impossibility of developing the laboratories and library in permanent place has been a great interruption to the proper development of the work. Fortunately this condition will soon be remedied as rapid progress is now being made in the preparation of the new site. Material progress has been made, nevertheless, in the organization of the staff of workers, and in the investigations, so that the year has been a valuable and active one.

A Study of the Fertilizer Requirement of Citrus Fruits.-This experiment, first outlined by Prof. Ralph E. Smith, was started on new land, the young trees being selected and planted particularly for the purpose. Twenty different plats were included, each of which was given a different treatment. Each plat contains 24 trees, 6 naval oranges, 6 valencia oranges, 6 Eureka lemons and 6 Lisbon lemons. Each plat is separated on every side from every other plat by guard rows of trees not included in the experiment, other than to prevent the influence of one plat extending over to another. The irrigation of each plat is separate, no water from one plat crossing onto another.

The trees were planted in April 1907 and are thus seven years old. They began bearing in 1910 and there has thus been four crops, but the freezes of 1913 and the preceding winter caused considerable damage, particularly to the lemons. The Lisbon lemon is a late bearer and this character, coupled with frost injury, has prevented a crop

production on these trees of a size sufficient to give any results of interest.

The following table gives the treatment of each plat and the average yield per tree for four years in number of fruits per tree :

AVERAGE YIELD PER TREE FOR FOUR YEARS IN NUMBER OF FRUITS

A few important suggestions can now be deduced from the results, but the experiment must run for a much longer period before the final results will be visible. The trees are still young and the early yields are naturally low.

The most noticeable factor is the high yields of the nitrogen plats, in particular plats C and S, treated with dried blood, and plat II, treated with nitrate of soda. The low yield of the untreated plats labeled "Nothing" is also worthy of note, considering the indifferent effects sometimes obtained in the use of fertilizers. Plate A and Q, treated with what is ordinarily designated as a complete fertilizer,that is, one containing what is supposed to be the nearly correct amount of potash, phosphoric acid and nitrogen-are in excellent condition.
