New YorK AGRICULTURAL EXPERIMENT STATION. 241 
Marshall and Brandywine, showed a marked increase in yield as 
a result of shading, Ridgeway and Wm. Belt showed little effect 
either way and Hunn showed a decrease. Perhaps in the case of 
Hunn, however, the decreased yield may be due to the greater 
severity with which this variety was attacked by leaf blight under 
the cover. 
The cover used at Geneva in 1903 was the one used at Shorts- 
ville the year previous. At Shortsville two varieties showed an 
increased yield under the cover and one showed a decrease. But 
it must be borne in mind that the plats in the check were severely 
injured by frost while those under the cover were protected. 
Perhaps this fact may account for a part or all of the increase 
apparently due to shading. 
At Penn Yan all varieties showed a loss under the treatment. 
This is probably due to interference with access of light, for as 
has already been stated, the cover used was a little heavier than 
the one used at Shortsville and at Geneva. The loss on different 
varieties in 1902 ranged from 14 per ct. to 70 per ct., averag- 
ing 40 per ct. for all varieties tested. In 1903 the average loss 
was only 18 per ct. the variety being Sample with some admix- 
ture of Marshall and other varieties: but in 1902 the loss on a row 
of a nearly similar mixture of varieties was 51 per ct. The 
season of 1903 was dry; in 1902 moisture was abundant. It 
appears then that shading is far more beneficial under conditions 
of deficient than of abundant moisture.
