ORCHARD SPRAYING DEMONSTRATIONS, 1909. 



By FRANKLIN SHERMAN, Jr., Entomologist. 



During 1909 the work in Apple Spraying Demonstrations has been 

 continued along the same lines as in 1908, except that whereas these 

 demonstrations were held in five counties in 1908, the work has been 

 extended to include twelve counties in 1909. 



The orchards in which the demonstrations have been given, together 

 with the dates on which the public meetings were held, are indicated 

 in the following table :

Two parties were placed in the field, one holding demonstrations 

 in four of the more eastern counties, and the other party holding the 

 demonstrations in the counties west of Raleigh. 



While the above table shows the date of the public demonstra-

 twelve places. Hence, in these twelve demonstrations we have made 

 visits and sprayed trees no less than thirty-six times. 



From three to five trees are used in the work at each place. One 

 of these is sprayed on only one side each time, in order to see if
