New York AGRICULTURAL EXPERIMENT STATION. 239 
of buds were just showing. On May 18 the foliage under the 
cloth was of a healthy green and was uninjured by frost while 
many leaves in the check were killed and many more injured. 
Twelve buds in as many clusters in each of the varieties in the 
open were examined and all found to be injured. Under the 
cover no Haverland, 5 out of 12 Wilson and 10 out of 12 Jessie 
were injured. 
At this time the buds had not developed ysl to permit 
of making extensive observations on the extent of injury to them. 
It was observed, however, that very few of the smaller-sized buds 
under the cloth showed any injury while all buds of any size not 
shaded were dead. 
On May 22 an examination of the blossoms was made to ascer- 
tain the extent of the injury by frost. The results are shown 
in the following table:

From these data it appears that out of a total of 241 blossoms 
examined in the check, 206, or 85 per ct. were injured, while 
among 247 under the cover only 18, or 7 per ct. were injured. 
Only two observations were made on the effect of shade on 
temperature at the time of a frost. On May 14 at 5:10 4. Mca 
thermometer in the check registered 30.5° and one under the 
cover showed 33°. On the following morning at 4:20 the tem- 
perature in the check was 28° andj under the cover 33°. 
EFFECT OF SHADING ON DEVELOPMENT OF DISEASE. 
At the Station in 1903 no disease appeared on any variety 
except Hunn, in either shaded plat or check. Hunn, which is 
known to be very susceptible to disease, was much affected by 
leaf blight in both plats, but very considerably the more in the 
shaded plat. Mr. Gillett reports that in 1902 there was much
