this case the shade-grown berries were softer and more melting 
in the mouth. As affecting shipping quality, only in the cases 
of Marshall and Ridgeway did the texture appear to be affected. 
In the case of Marshall the effect would be of little if any practi- 
cal importance. But in the case of Ridgeway, naturally a rather 
soft berry, the. shade-grown fruit would not stand shipment to 
distant markets though it would be all right for local trade. 
As to sweetness, the first pickings from all varieties in the check 
at Geneva were sweeter than those shaded; but this difference 
practically disappeared as the bulk of the crop came on and later. 
The first pickings of Brandywine showed perhaps the greatest 
difference in this respect. Brandywines from the open were 
notably sweet but small. Wm. Belt showed the least difference 
in sweetness between the two plats. At Penn Yan no difference 
in sweetness between the shaded and the unshaded fruit could 
be detected. 
Through the courtesy of Dr. L. L. Van Slyke, chemist of this 
Station, determinations were made by Mr. F. D. Fuller, assist- 
. ant chemist, of acid and sugar in samples of Marshall and Ridge- 
way, Shaded and unshaded, of the picking of June 19, 1903, at 
Geneva.

These results as regards acid content were surprising. The 
shaded berries were much the less sweet; but this was not due 
to the presence of more acid but of very much less sugar. There 
was actually a less percentage of acid in the shaded than in the 
unshaded fruit. 
PRACTICAL RESULTS OF THE EXPERIMENT. 
The practical outcome of this experiment is as follows: With 
the thinner cover, productiveness has been very considerably
