been done in the spring when the buds are swelling, ending when 
the tips of the young leaves began:to make their appearance. . The 
sulphur wash was prepared after the standard formula, while a 
commercial preparation of this mixture was employed at a dilution 
of one part to nine parts of water. Miscible oil was used at the 
tate of one gallon diluted with nine gallons of water, while the 
kerosene emulsion contained 15 per ct. of oil. 
In addition to spraying entire blocks, comparative tests of these 
remedies have been made on individual trees, which were among 
the worst infested on the Station grounds. Each tree was divided 
into thirds, fourths or fifths, according to the number of mixtures 
tested, and provision was also made for checks. To confine a par- 
ticular treatment to the portion of the tree desired and to avoid 
re-treatments while applications of the various remedies were being 
made on other parts, cloth screens were employed in all of these 
operations. 
Results on mite.—The first year’s applications of these remedies 
destroyed a large percentage of the mites. During the summer of 
1907, the work of the mite on the sprayed trees was very slight as 
compared with that of the previous year or that on the checks. 
None of the trees was completely free, but enough of the mites 
were killed to prevent the pimpling of young apples and to pro- 
tect a large percentage of the foliage from injury. The applica- 
tions in the fall of 1907 and the spring of 1908 were equally effec- 
tive and the foliage in this orchard, with the exception of a few 
leaves on an occasional twig, was generally very clean. The smaller 
tests also indicated that, if the applications are equally thorough, 
there is very little difference in the effectiveness of the different 
sprays. The results of these experiments show conclusively, also, 
that the blister-mite is never likely to cause important injuries in 
orchards that are well sprayed each year with a sulphur wash or 
oil emulsions as is required for the proper treatment of the San 
José scale. 
ORCHARD ITI. 
This orchard belongs to E. C. Green, Victor, and comprises about 
feeecreo- Liere are 465, tréessewhich are 30-years of age. The 
leading varieties are Baldwin, Seek-No-Further, Wagner and Spy. 
The orchard has been systematically sprayed for the common in- 
sects and diseases and is regarded as one of the most attractive 
and productive plantings in the community. Originally the orchard 
was given very thorough cultivation, but for the past two years it
