regularly sprayed for the ordinary insects and plant diseases and 
has in all respects been given excellent care. 
The mite made its appearance in destructive numbers for the first 
‘time in 1906 in the younger orchard, and in 1907 it was abundant 
in the older orchard. The varieties that have shown the work of 
the mite most extensively are the Baldwin and Gilliflower. The 
Owner estimates that the mite has caused a decreased yield in the 
younger orchard amounting to about 250 barrels each year. The 
condition of the foliage of the Gilliflower was worse than that of 
the Baldwins and all of the fruit was of little value, as it was much 
undersized. ‘This was attributed to the work of the mite. For the 
treatment of the trees the home-made lime-sulphur wash and a 
commercial concentrated preparation of this mixture were em- 
ployed. The applications were made during the week of April 13-- 
20. The amount of wash applied per tree was ten gallons, which 
was larger than necessary because of the treatment of the trunks 
and large limbs. ‘These could have safely been left unsprayed. A 
power sprayer was used to make the applications. Several Bald- 
wins and a block of 23 Hubbardstons were left unsprayed as checks. 
Results on mite—— The effectiveness of the sulphur wash for the 
control of the blister-mite in an old commercial apple planting was 
in none of the experiments more strikingly demonstrated than in 
this orchard. While there were occasional twigs that showed some 
affected leaves, the foliage generally was clean, and, as in other ex- 
periments, the appearance of the trees afforded a striking contrast 
with the condition of the checks, which as usual were abundantly 
infested with the mite. Mr. Lafler is so much impressed with the 
efficient qualities of the sulphur wash as an orchard spray that he 
has erected a steam cooking outfit, and plans to make one treat- 
ment of this mixture each year during the dormant season in place 
of the usual application of the bordeaux mixture at that time. The 
home-made wash and the commercial concentrated preparations 
of the lime-sulphur wash were equally effective in controlling the 
blister-mite. 
ORCHARD IV, | 
This orchard belongs to C. Willard Rice, Seneca, and comprises 
six acres. The number of trees is 180 and they are about 40 years 
of age. The varieties are principally Baldwin, Greening and King. 
This orchard has been cultivated for the past eight years and 
treated with barnyard manure and chemical fertilizers. The yields 
have averaged about 4oo barrels each year. Injuries to foliage
