Total amount to be completed, 60 units. Of this amount 36 units shall consist of major courses and

shall be distributed as follows:

From the above it will be seen that, while a student's major subject may be agronomy, for example, if he should elect further study in genetics, giving special attention, let us say, to wheat improvement, this work would very properly fall under the head of courses correlated with the major subject, thus leaving the full time allotted to the major subject free for the broad training courses in agronomy. If work proceeded satisfactorily during his junior year, his genetics topic might be acceptable as his bachelor's thesis, to be completed under the joint supervision of the professor in charge of the student's major subject and the instructor in genetics.

Similar co-ordination is possible between genetics and pomology, citriculture, viticulture, floriculture, olericulture, entomology and animal husbandry. The following diagram is designed to show more concisely the possible co-ordination in instruction which we have been considering. It should be understood that the organization of the Department of Agriculture is primarily around fundamental subjects and not around industries. But within the various divisions we have already recognized certain men as specialists on certain important crops and animals in California. It is likely that specialists on other crops and animals will be recognized in the future:

In the diagram upper division students who elect genetics are shown working between the specialists in genetics and the specialists in crops and animals. This does not mean that any student would report to two different instructors in connection with the same course. If regis

tered in genetics, he would be responsible to an instructor in genetics. The co-ordination suggested would be secured by co-operation between the genetics instructor and the specialist in the crop or animal being studied. This implies mutual understanding and frequent conferences between the instructors concerned. It is obvious that such

a plan can serve as a satisfactory working basis only when the various specialists are in one department and thus are responsible to one chief, who will understand the special arrangements it is sometimes necessary to make in order to carry on field study and who in various other ways can guide and facilitate this desirable co-ordinated instruction. The diagram indicates that ideally the division should be four-sided in order to insure complete co-ordination with the four great groups of agricultural activities represented in the Department of Agriculture. Eventually it must include specialists in genetics who are sufficiently conversant with pomology, with floriculture and olericulture, with agronomy and with animal husbandry, so as to be able to co-operate with the various specialists in those divisions advantageously. On account of the location of our animal husbandry division at the University Farm, it is highly important that there be a specialist on animals in this division, although it is conceivable that his material for special instruction and research might be limited to insects. Our students choose their major subjects during the sophomore year. Those electing animal husbandry are not permitted to go to Davis before the last half of the junior year. But some who choose that major desire further work in genetics, and it is clear that they will be better prepared for the important and expensive work of breeding farm animals if they have continued to delve into the principles of genetics in connection with some special problem, even though the material used be insects or mice. The specialist in charge must be in and of the division; the division must work harmoniously as a unit within the department, being intimately related to all the other divisions concerned.

At present there are seven upper division and two graduate students enrolled for elective work in genetics. Their problems include work with the following plants: maize, cotton, tomatoes, cabbage, alfalfa, lima beans, various cucurbits, lettuce, sweet peas, Hunnemannia, Eschscholtzia, Browallia, cosmos, asters, etc. The work includes studies of variation and experiments in selection, hybridization, and the testing of hybrid progeny.

Instruction is the only function of the Division of Genetics we have discussed thus far. However, it is a recognized policy of the University that all instructors should engage in research to the fullest extent possible. It is generally believed that the best teachers are those who give a part of their time to study and self-advancement. In other words, instruction is vitalized by research. Dean Hunt recognized this principle in his general directions to division heads when he advised the arrangement of each instructor's courses, as far as possible, in one half-year so as to leave the other half-year free for research and extension. for extension work this division has not yet reached the stage of development which makes possible much attention to this phase of the Department's activities.

In

The research work under way consists of three projects and several student problems. The first project includes the study of a new form of Juglans Californica, concerning which a paper has appeared in the agricultural science series of the University of California Publications. connection with this study a number of experiments in hybridizing our native black walnut and certain native oaks have been made. The appearance of the first lot of second generation seedlings next spring is awaited with considerable interest. The first generation seedlings are all similar to the black walnut, which was the female parent of all. The second project involves an attempt to secure a new series of derivatives of the Chinese saucer or Peen-to peach, which will be of greater commercial value than similar derivatives that were developed in Florida

several years ago. The Peen-to possesses certain qualities which it is desirable to combine with the good qualities of standard commercial varieties. Through the assistance of Mr. C. O. Smith, of the Whittier Laboratory, a number of crosses have been made, some first generation seedlings have been fruited and of some of these second generation seedlings will be grown next year. It is hoped to expand this project to include hybridization experiments with various forms of Prunus. The third project consists of experiments in the production of hybrids in lilies, brodiaeas, and calochorti.

A discussion of the Division of Genetics would hardly be complete without giving some attention to present housing and equipment and to future needs. The only room given over to the exclusive use of the division is an office in Agriculture Hall. Besides serving for the usual work of an office, this room is now used for the division's index to references and specimens, for the publications belonging to the division, for the storage of seeds valuable enough to be kept in a fire-proof building, and for the filing of photographic negatives. Classes in laboratory work are accommodated in the plant pathology laboratory in Agriculture Hall. This room was in no way planned with special reference to instruction in genetics and considerable inconvenience is occasioned by lack of provisions for handling herbarium material, and the students' kits or outfits for laboratory and field study. Space for these purposes has been provided temporarily in the agricultural museum.

As for equipment, only a small amount of herbarium material has been accumulated thus far, owing to the lack of room in which to care for specimens. Only such equipment for student laboratory work has been purchased as was urgently needed so as to avoid over-crowding the laboratory, which is shared with another division. A small amount of equipment for cytological research has been purchased. This is being used by the writer at present in one of the offices belonging to the Division of Entomology. This

is a temporary arrangement during the absence of a member of that division. It is not known where this work will be carried on after his return.

Ample field and garden space is at present available for the work of this department. This is very fortunate as it is highly desirable that such facilities be available and convenient to instructors and students. A small room in an out-building has been fitted for storage and preparation of seeds, bulbs, tubers, and for stakes, labels, and other material needed in field and garden work.

Up to the present the only greenhouse space available for instruction and research has been one unit of the old conservatory, and this is shared with another division which has cultures of cotton and grains in considerable number. It is hardly necessary to state that research work involving pedigree cultures cannot be carried on under such conditions. A greenhouse unit for the exclusive use of this division is urgently needed and I trust will soon be in process of construction. Some animal rooms will soon be needed. This space will probably be provided in connection with an outbuilding designed for the entomology division. Laboratories especially designed for instruction and research in genetics are urgently needed. There should also be a room for publications, index files, and a few of the standard periodicals.

In conclusion, I may say that while the division finds itself confronted by many and diverse problems in organization and instruction, while it is continually reminded that its existence is one of the unique features of the foremost college of agriculture in the land, and, hence, that the responsibilities resting upon it are of serious import, at the same time the opportunities before it are inspiring. Strong is the belief that the problems of co-ordination within the department will be solved and keen is the hope that any problems of interdepartmental relations that may arise in the future will be satisfactorily adjusted. Of the study of genetics there is enough and to spare, and any
