open, and at each place we explained that two more treatments with 

 the same material would be given to the same trees. The second 

 treatments were given just after the blossoms fell, — April 16th to 23d

 began. In two or three places the attendance was satisfactory. The 

 critical and the faint-hearted could have easily declared the demon- 

 stration work a failure and with good show of reason. 



But by midsummer the treatments began to tell. We requested 

 reports from all five growers in mid-July, and every one reported a 

 distinct advantage in favor of the sprayed trees. (Of course this is
