19-21. Three trees of Grimes Golden. Location, Chart 7, Trees 

 23, 24, 25. In 1912 each tree bore well, the fruit infested, some 

 drops picked up occasionally, the remainder allowed to lie. For-

 22, 26, 30, August 5, 11, 23, 27, September 5.. Four quarts of 

 material applied to each tree at each application. A hand pump 

 used. Each tree bore a large crop. From each about 1 3^ bushels 

 of apples were removed and recorded. Results of each: Tree 

 No. 1, apples counted, 376; total punctures, 779; proportion of 

 apples free from punctures, 34.8 per cent. Tree No. 2, apples 

 counted, 448; total punctures, 808; proportion free from punc- 

 tures, 27.9 per cent. Tree No. 3, apples counted, 347; total
