that the yields for this year were very uniform over all the plats 

 including the checks and that this tended to equalize the yields 

 of 1911. 



MINER VINEYARD. 



The Miner vineyard is situated on a level piece of low-lying land 

 of the Dunkirk clay type, which is as a rule much improved by 

 underdrainage. The rows run in a general north and south direction 

 and vary in length from 40 to 59 vines. Each plat consists of a single 

 row separated from the others by discard rows. During the period 

 over which this experiment has run, the vineyard has not been 

 sprayed. Severe infestations of the grape root-worm and the grape 

 leaf-hopper occurred in 1911 and 1912 respectively. Just how 

 much these insects have lessened the yields cannot be determined, 

 but judging from the appearance of the vines it was considerable. 

 Table XII gives the order in which the plats occur in the vineyard, 

 the annual yields per acre for each plat and the four-year average.

 another nor of that of any application over the checks. They only
