180 Investigations in Plant Pathology 



a cheaper and more practical means of applying the remedies. The results 

 of the potato and tomato-rot experiments have encouraged us to give the 

 copper remedies a thorough trial for these diseases, and special attention 

 will be given to the comparative cost of the different preparations, the best 

 time to apply them, and the number of applications necessary. The grape 

 work will be continued, as there are yet many points in the treatment of 

 black-rot and anthracnose which need further elucidation. We have now 

 under way some experiments in the treatment of the diseases of cereals, this 

 work being chiefly confined to the smuts. 



Aside from the grape maladies, the " principal diseases under 

 treatment [were] scab, rust, bitter-rot, and powdery mildew of 

 the apple; leaf-blight of the pear and quince; potato-rot and 

 blight; melon blight, strawberry leaf-blight . . . and peach yellows. 

 In two cases, namely, Michigan and Wisconsin," Galloway re- 

 ported,^ "we co-operated with the [state] experiment stations." 

 In the Journal of Mycology, " some of the more practical subjects 

 discussed [had been]: (1) Treatment of apple scab, by Prof. 

 E. S. Goff, of the Wisconsm Experiment Station; (2) treatment of 

 potato rot, by Clarence M. Weed, of the Ohio station; (3) peach 

 rot and blight, by Dr. Erwin F. Smith," due to Mouilia fructigena, 

 Persoon.* 



The " first systematic attempt on the part of any station or 

 organized body in the United States " ^ to make " a thorough study " 

 of plant diseases had taken place at the New York experiment 

 station under Arthur. There, in four of its annual reports, he had 

 published on " a great number of important diseases," and while 

 the " keynote to the practical work of treatment had not yet been 

 struck" this was to follow "as a natural result of the studies" 

 made during these pioneering years. Even as late as the year 

 1885, Galloway pointed out,*' " there were only three institutions 

 besides the Department of Agriculture making an organized effort 

 in the way of teaching or in experimental work of this character." 

 Burrill's work in Illinois and Farlow's work at Harvard were the 

 two other principal research centers until the provisions of the 

 Hatch Act made possible the establishing of other centers in
