each side, and large skips sometimes affect more than do single skips. 
2. Small plants (early varieties) cannot make use of much 
extra root space; and loss of stand with them gives an almost equal 
loss of yield. 
3. Deep rooting plants like Rurals and Carmens may or may 
not make use of extra space. There seems to be no uniformity as 
to the effect of stand on per cent, of culls.

sent the average yield per hill in a perfect stand, then the firsts and 
seconds recover together an average of .35 pounds, or about 34 of 
the loss of one hill. 
5. A similar amount is made up on the other side of the skip. 
6. The hills on either side of a single skip make up one half 
the loss. 
7. The skips of more than one hill are positive losses of yield 
except for the zveight of one half of one hill. 
STANDS IN GROWERS' ElELDS. 
Average Stands 70 to 75 Per Cent .—An extensive examination 
of stands in fields over the state, in growers hands, convince us that 
among Pearls and Rurals which constitute nine-tenths of our out¬ 
put, 70 or 75 per cent, is an average stand. An examination of 
stands secured with these varieties on our plots will convince the 
reader that a stand of 85 to 90 per cent, is attainable in field prac-
