equalizing this, though it has apparently not been tried so 
far to any extent by experiment stations. For the last two 
years, in our test with 52 varieties, a standard kind has been 
selected and planted every 7th row or 21 feet apart. The 
yields of these check plots were found to differ widely, but it 
was seen that where the check plots yielded best, the best 
yields of other varieties were obtained, and vice versa. The 
range in yield, even on the fairly uniform piece chosen in 
1902, was from 282 bushels to 506 bushels for the standard 
variety. With such difference as this due to other causes
