3 For compa-ison , the yields of the naked varieties are given in bushels of 48 pounds. The actual yield 

 in bushels cf CO pounds, the standard weight, would be one-fifth less. 



* Yield not recorded. 



During four years of this period (1909 to 1911 and 1913), computed 

 yields were figured frcm the use of check plats. The computed 

 yields are given in Table XVI, with the average actual yields for 

 comparison.

1 Tho check plat ; in 1912 were not thrashed; therefore, no computed yiTds arc given for that yenr. 



2 For comparison, the yields of the naked vari?l ies are given in bu .hels of 48 pounds. The actual yield 

 in bushels of GO pounds, the standard weight, would bo one-fifth less. 



Table XV shows that the average actual yield of all varieties 

 grown in 1907 was 85.5 bushels; in 1908, 30.5 bushels; in 1909, 37 

 bushels; in 1910. 28,7 bushels; in 1911, 10 bushels; in 1912. 38.4 

 bushels; in 1913, 32 bushels; and for the 7-year period, 30.3 bushels. 



SI'MMARY OF BARLEY FIELDS.

 group represented in the trial were selected. The actual and com-
