the tests, the chances of accidental cross-pollination were reduced 

 to a minimum. 



xifter the blossoming season had passed, a record was made to 

 show which clusters had set fruit and which liad failed to set fruit. 

 When the fruit was ripe each cluster under test was rated on the 

 scale of 100, according to the percentage of a full cluster which 

 was found. A perfectly formed cluster was rated 100, a half- 

 filled cluster was rated 50 and others were rated in a correspond- 

 ing manner. 



location of the vineyards. 



The tests were conducted in 1899 in three quite widely sepa- 

 rated localities: In the Station vineyards at Geneva; in the vine- 

 yards of E. Smith & Sons at Highlands, on the east bank of 

 Seneca lake, near Lodi ; in the vineyard of Mr, E. C. Gillett, 

 Penn Yan, jST. Y. Our acknowledgments are due the gentlemen 

 who have consented to allow the experiments to be conducted in 

 their vinevards, and also to Mr. Horace W. Gillett who assisted in 

 the work at Penn Yan in a very careful and satisfactory manner. 



The Highlands vineyards are on soil which is derived largely 

 from broken shale. The other vineyards mentioned above are on 

 clay loam. 



cross-pollination. 



The cross-pollinating was done at Highlands, June 12. At 

 Penn Yan it was done June 12, with the exception that Brighton 

 and Salem were crossed each upon the other June 13. At the 

 Station the work of cross-pollinating was done at convenient times 

 during the blooming period from June 10 to 15. 



The cross-pollinating which was dene at Highlands was under 

 the direction of C. P. Close. The plan there followed was to un- 

 cover the cluster which was to receive the pollen. Th3 cluster 

 selected to supply the pollen was then taken from the bag in 

 which it had till this time been kept, and fastened to the first men- 

 tioned cluster. Both clusters were then covered with the bag
