another set of fertilizers in order to carry on the work through the 

 season. 



The amount of benefit that the farmers will receive from these 

 experiments cannot be measured by the success or failure of their 

 experimental plats alone. Where the experiments were carried on 

 properly, the farmers were usually wide awake and energetic and had 

 been in the habit of experimenting more or less. 



In some other instances the experiments were almost total failures 

 because the farmer had not been in the habit of experimenting, in fact, 

 did not know how to do it, or had no time for it. To such this work 

 was a revelation. The probability is, that such farmers, even though 

 their experimental plats this year were failures, have been helped 

 proportionately more than those who had successful experimental plats 

 and had been accustomed to experimenting. 



The experiments have been all the more beneficial and instructive 

 because the farmers have done the work themselves and, therefore, 

 were much more interested in it than they would have been had 

 it been done by the Station and the results then read by the farmers. 



In September, a circular concerning field experiments with fertilizers 

 was sent to each experimenter, giving directions for harvesting the 

 crop on each experimental plat, and for making out and sending the 

 reports to the Station. Up to the present writing, nearly all the 

 reports have been received and, on the whole, they are very satisfac- 

 tory, considering that this is the first time that the experimenters have 

 made such reports. 



In the near future we expect to publish the results of the summer's 

 work with fertilizers, so that all can see what the farmer can do in 

 carrying on experimental work.

The final results from our extensive experiment against the peach 

 borer, extending over a period of three years, were ascertained during 

 the past summer. This investigation has revealed some striking and 

 valuable facts which will add much definite data to our knowledge of 

 how to fight this serious peach pest. We are now collating and
