Ixviii Department of Plant Pathology, 



office a call for another field laboratory for the investigation of 

 peach yellows. Aside from the fact that there is not sufficient 

 money available in the department to conduct all these investiga- 

 tions without the growers' co-operation, there is the advantage in 

 such an arrangement that the grower, being financially interested, 

 will give the investigations more careful attention and be more 

 likely to take advantage of the results obtained. The establishment 

 of the lime-sulphur fellowship marks the first of a number of 

 fellowships which it is hoped may be established in the Department 

 of Plant Pathology. At least two other fellowships are in sight, 

 and we believe more will follow. By the establishment of fellow- 

 ships by the growers or commercial companies, well-trained young 

 men may be employed at a minimum expense, since they are at the 

 same time getting their training for an advanced degree. 



in. EXTENSION. 



The extension activities of the Department of Plant Pathology 

 may be classified as follows : 



(a) Teaching. — The department during the past college year 

 offered two courses to men in Winter Courses, Farm Botany, and 

 Plant Diseases. The Farm Botany, however, does not naturally 

 belong to the Department of Plant Pathology and will not be offered 

 in that department another year. It is proposed, however, to offer 

 two courses in Plant Diseases, one to men who come to Winter 

 Courses for the first time, and another to those who have already 

 had our first coiu-se in Plant Disease work. 



(b) Demonstration and co-operative experiments. — The Depart- 

 ment of Plant Pathology offers a number of co-operative experi- 

 ments in connection with the work of the Experimenters' League 

 of the State. However, the number of growers taking advantage 

 of this has never been large and was fewer last year than in the 

 preceding. The chief difficulty in successfully conducting this sort 

 bf work is that not sufficient funds are available with which to push 

 it. To make co-operative experiments of this type successful we 

 believe it will be necessary to visit the experimenters at least once 

 and often several times during the season to see that the work is 

 being properly performed and results accurately obtained. Not 

 only are there no funds available for this work, but men are not 

 available for the necessary traveling which would be entailed. 

 However, in this connection our seven field laboratories located in 

 different parts of the State have, we believe, been very eft'ective
