i8 Report of the President. 



(b) Satisfactory progress has been made in the investigations de- 

 scribed last year into the diseases of grapes, beans, ginseng, peaches, 

 apples, plums, etc., and in the further study of lime-sulfur as a fungi- 

 cide. Although none of these investigations has been completed, much 

 valuable data have been gathered, some of the results have been published, 

 and other bulletins and reports are now ready for the printer. Most of 

 the work of this department is done in cooperation with growers and 

 commercial firms, and the industrial fellowship plan, described elsewhere 

 at more length, has proved most satisfactory and efifective. It is a 

 high tribute to the work of this department that during the year funds 

 have been provided by individuals and companies for the establishment 

 of seven new fellowships. The department now finds itself unable to 

 meet the demand for these fellowships, partly because of lack of good 

 men and partly because the maintenance funds of the department are 

 not large enough to provide for the equipment of the necessary field 

 laboratories. The fellowships established during the year have made 

 possible the beginnings of investigations into the use of sulfur and its 

 compounds as fungicides ; the heart rots of forest, shade, and fruit trees ; 

 the effect of cement dust on fruit, foliage, etc. ; the diseases and insect 

 pests of fruit and fruit trees and methods of their control ; and the 

 diseases and improvement of potatoes and other field crops. 



(c) The conduct of investigations at nine field laboratories, the holding 

 of five demonstration field meetings, the direction of many cooperative 

 experiments, the preparation of exhibits for fruit-growers' meetings, the 

 writing of over 4,000 letters, the sending out of circular letters and of 

 articles for newspapers in regard to certain plant diseases, are all features 

 of the extension work of this department. The possibilities and oppor- 

 tunities for service are limited and restricted only by the lack of funds. 



VI. Department of Soil Technology. 



(a) The nine courses offered by the department this year were taken 

 by a total of 227 persons, of whom 12 were graduate students. 



(b) Research has been actively carried on and some of the results 

 published in scientific magazines and in two bulletins in the Experiment 

 Station series. Certain results obtained from the investigations con- 

 ducted by the department have a very practical bearing. For example, 

 it has been demonstrated that the growth of a legume with a non-legume 

 gives the latter a greater protein content than when it is grown alone ; 

 from the practical standpoint this is important because it suggests a 

 method for increasing the protein of crops raised for stock food. Again, 

 it was discovered that the amount of protein in alfalfa grown on a limed
