ceeding with soda hyposulphite, as described in the experi- 
ments cited. 
The spraying, which was done with the so-called Little Gem 
force-pump fitted with a “Climax” nozzle, was made upon the 
west half of the tree only, and was commenced May 10, just as the 
leaves were expanding, and repeated after every hard rain until 
July 24 eight applications having been made in all. 
The tree blossomed alike, apparently, on both the sprayed and 
unsprayed portions, but the crop of fruit matured was much 
larger on the sprayed part and, as the following figures will show, 
was of much better quality. 
On September 12 a quantity of fruit was picked from the 
sprayed and from the unsprayed parts of the tree and each lot 
assorted into three classes, in order to determine their relative 
injury from the disease. In the first quality were put only fruits 
nearly or quite free from scab; in the second, those that were 
considerably scabby, but not so much as to distort their form or 
prevent them from acquiring their normal size and.in the third 
those which were distorted in form or diminished in size by the 
erowth of the fungus.* The results secured were as follows:

More than 627 fruits did not mature on the unsprayed part of 
the tree. On the sprayed part, however, many more than 1560 
might have been gathered. If we ascribe the larger crop on the 
sprayed part to the influence of the application, it is evident that 
_ the figures express but a small part of the benefit resulting from 
_ the treatment. Aside from the difference in crop, the fruits on 
the unsprayed portion were inferior in size to those on the other 
part. 

} * This classification is necessarily somewhat arbitrary, but as the assort- 
_ ing was done with care, it is believed that the figures represent the true 
proportions of the amount of injury wrought by the scab. Almost all the 
fruits were somewhat scabby in the cavity about the stem, but if not 
affected elsewhere this did not exclude them from the first quality.
