summer there were prospects for a good harvest but in August a 

 hailstorm ruined the crop. The fruit was not picked as the crop 

 had no experimental value. Even the vines were severely injured 

 by the hail. Another episode of the year was a veritable scourge 

 of leaf-hoppers which nearly defoliated the vines. 



1908, 1909, 1910, 1911. — All vines to enter in the discussion 

 in this Bulletin had come into bearing in or before 1908. The 

 vineyard treatment during these years was that given commercial 

 plantations in the Chautauqua Belt. Another disaster must be 

 recorded for the year 1910 when a second hailstorm so damaged 

 the crop that it could not be considered in the study of results. 



RESULTS OF THE EXPERIMENT. 



Grafted grapes have had a trial of eleven years in this experi- 

 ment. In spite of the time that has been given to the work, of 

 expense to meet every need of the vineyard, and of every precau- 

 tion to carry on a careful trial, the results are not satisfactory. 

 The data lack precision and fullness — lack quality and quantity. 

 The start was on a road that seemed to lead straight ahead but 

 there were so many obstacles in the way that progress was mostly 

 through byways and backways. The experiment is all but a fail- 

 ure because of the loss of many vines at the start, because of poor 

 stock, lack of knowledge of the best means of grafting, the freeze 

 of 1904, the hailstorms of 1907 and 1910, and fidia. 



Possibly no report should be made on an experiment that has 

 suffered as has this one. But throughout the test the grafted vines 

 have behaved differently from the ungrafted ones and in some re- 

 spects they were better plants, so that it may be worth while to 

 give the results of the experiment. Meanwhile we have started a 

 similar experiment elsewhere from which we shall hope to give in 

 time a more satisfactory report. 



Grafted vines are more fertile. — Greater fruitfulness has all 

 along characterized the grafted vines. Yet it is most difficult to 

 show on paper precisely how much more productive the grafted 

 vines have been. There has been but one year, 1911, in which
