The elevation above sea level is about 900 feet and killing frosts are likely 

 to occur before October i. 



The plan of the experiment was typical of all tests made, so details may 

 be given here. Rows were planted across the plat so that as nearly as 

 possible all varieties had an equal chance. Each variety to be tested 

 was given a consecutive number in each separate test. Beginning on one 

 side of the plat with variety No. i , a row of each variety was planted as 

 numbered. Then the series was repeated in order to have duplicate rows 

 of each variety in the experiment. In harvesting the corn and fodder 

 the weights of both rows of each kind were taken together as the result 

 for that variety. The yields of air-dried corn and field-cured stover were 

 determined at Ithaca, but this was not done uniformly for all other 

 experiments. 



Fifty varieties were planted in 1909; five of these failed to grow here 

 or in any of the other tests. Th^ four dent varieties procured from 

 Illinois did not mature here or elsewhere in the tests. In 19 10 twenty 

 varieties were tested. Eighteen of these were tested the first year, and 

 two the second year only. Beside these two varieties, only those from 

 which results were secured for two years are shown in the table below:
