since the particular end in view was to test the effect of a late application 

 on larvae of the second brood. There were thus included in the experiment 

 eighty-four trees of fall and winter varieties. These trees with certain 

 exceptions were sprayed four times with Bordeaux mixture to which one 

 pound of Paris green was added to each two hundred gallons. The appli- 

 cations were made May 13, June 11, June 25, and August 11, and at each 

 application certain trees were omitted. In the column marked "No. of 

 applications" the figures opposite any particular tree indicate which of the 

 sprayings that tree received. Thus, 1 stands for the first application, 

 May 13; 2 for the second, June 11, etc. In like manner, 1, 2, 3, 4 indicates 

 that the tree received all four applications; 2, 3, that it received only the 

 second and third. At the time the first application was made the condition 

 of the calyx was noted for each variety and this is recorded in the column 

 mai-ked "Condition of calyx," as open or closed. Immediately after the 

 third application I, personally, counted the apples on each tree, and again 

 July 20 went over them and counted all that showed indications of being 

 infested by larvae of the first brood. When the fruit was gathered it was 

 carefully examined, the apples that showed the least indication of injury 

 counted, and the percentage of wormy to sound fruit estimated.
