per cent., it is not surprising that practically no spraying is 

 reported from them. The map shows that spraying is more 

 general in the leading fruit growing sections of the state and 

 where a few growers have been spraying for some time. 



In the 111 towns there were reported the names of 345 par- 

 ties who sprayed. To each of these a letter was sent requesting 

 a reply to the following questions : 



1. In what year did you first spray? 



2. How many bearing trees do you spray on your own place ? 



3. Do you spray for neighbors? If so, give their names and 

 number bearing trees sprayed for each. 



4. Against what insects or diseases do you spray particularly ? 



5. How 2nany times during the year do you spray? Give 

 approximate dates. 



6. What insecticides and fungicides do you use and at what 

 strength ? 



7. What sprayer do you use? 



8. What does it cost you to spray? Total, or per tree. 



9. How much profit per tree do you think you receive from 

 spraying? 



10. If you can compare sprayed with unspraj^ed trees, what 

 difference have you observed as to quantity and quality of picked 

 fruit ? 



At this writing, December 20, one hundred replies have been 

 received, which is a very large proportion to secure for such a 

 questionaire, especially as no rej^ly envelope was sent, and which 

 number enables us to determine a fair average. 



The replies to the questions have been carefully studied and 

 are summarized as follows : 



1. The year in which spraying was commenced was given by 

 96 parties and is sliowii tiraphically in Figuic 22. This shows 

 that over 60 per cent, sprayed for the first time in 1908 and 

 1909. Furthermore, those who are reported as spraying prior to 

 1900 usually state that they sprayed but irregularly, mostly for 

 the canker worm. 



2. Ninety-five reports give an aggregate of 22,305 apple trees
