comparatively free from warts. I have cut out all warts that 

 appeared this season and shall spray early this spring, before the 

 buds start." 



REPORT OF BENJAMIN P. WARE, 



MARBLEHEAD, MASS. 



"■ Apple and pear trees and potatoes were treated as follows : 



Apple. May 9th. sprayed with the Bordeaux mixture, with Paris 

 green 1 lb. to 120 gallons. June 12th, made second application. 

 The petals had just, fallen. 



The results noticed were that the tent caterpillar and the canker 

 worms were all killed and that no injury could be detected to the 

 foliage, from the per cent, of Paris green used. 



"Very few apples were affected by the codling moth, and the 

 Bordeaux mixture remained on the foliage the entire season. 



Pears. May 9th, applied the Bordeaux mixture and Paris green, 

 1 lb. to 120 gallons, to Flemish beauty pear trees. The fruit had 

 cracked badly for years, but this season not quite so badly.* 



Potatoes. June 12th, sprayed a field of potatoes with Paris green, 

 1 lb. to 120 gallons of water. The Douglas barrel pumj) was used, 

 mounted on a wagon, the horse going between two rows and the 

 wheels between the next two on either side, and eight rows were 

 spiayed at a time. The beetles were all killed and the pump worked 

 to a charm." 



REPORT OF H. A. COOK, 



SHREWSBURY. MASS. 



Mr. Cook treated grape vines, plum and peach trees, and reports 

 as follows : 



Grapes. " Sprayed vineyard. May 11th and June 13th with the 

 Bordeaux mixture, four rows of 35 vines each being left as checks. 

 The common knapsack pump was used to apply the mixture. 



*It has been conclusively shown that the common fungi attaclcing our fruits, will grow 

 at any time during the summer when the conditions of moisture and temperature are 

 ■right. Rains quickly wash out the little soluble capper there is in the Bordeau.v mixture, 

 and it is not safe to depend upon one or two applications for the destruction of their spores 

 during the three or four months when it is possil)le for them to grow. Had the trees been 

 sprayed at intervals of about two weeks, varying the time according to tlie weather, up 

 to Aug. 1st, more favorable results would probably have been obtained.
