on the diseases of crops has thus far been most satisfactory and 

 congratulatory. It is expected that it will require from three to 

 four years to complete the training of these young plant doctors. 

 They devote at least eleven months of the year, in most cases, to 

 such study and investigation. That means from four to five 

 seasons in the field, in intimate relation with the crop, the diseases 

 of which they are working to control. They get practical expe- 

 rience. At the end of this period they receive their Ph.D. degree, 

 if their scientific attainments warrant it, and as expert pathologists 

 are ready for their life work. They are high class, expensive men. 

 Where are they to find their opportunity for a livelihood? I 

 answer: in that locality, county, or state where they were trained. 

 They are worth more to those growers with whom they have lived, 

 for four years, than to any one else and those growers will retain 

 them as experts on the diseases of their particular crops. Our 

 plan is that they shall he maintained by groups of growers as their 

 expert on our staff, the state providing facilities for these men to 

 continue their labors for the benefit of the growers of the state. 



Some Results. 



If it is true that the proof of the pudding is in the eating, it is 

 equally true that the proof of this scheme is in the results obtained. 

 The most convincing proof of the success of the plan is the con- 

 stantly increasing demand of the growers for more of these field- 

 laboratory -fellowship cooperations with the College. Not only 

 in Plant Pathology but in economic entomology as well are these 

 fellowships being established. 



You will better appreciate the value of these young experts if 

 I show you some of the results which they have obtained for the 

 growers of the state. I shall select the work of two of our men. 



The Lime-Sulfur Investigations. 



The serious injury to the fruit which so frequently results where 

 bordeaux is used in the control of apple scab convinced our growers 

 that some substitute equally effective but less injurious must be
