These fi2;ures must be taken in connection with the last ta- 

 ble, as they show the per centage of increase and not the abso- 

 lute gain, thus the gain on the Noithern field corn from July 26 

 to September 6 is 125, but on July 26 the Northern field corn 

 had 1251^ per cent of dry substance, while the Southern corn had 

 only 8.75. 



Comparing the dry substance in one hundred pounds of 

 corn at the several dates and we shall find the following: to be 

 true : 



Gain of dry substance from' July 26 to Sfept. 16. ' Aug. ig to Sept. 16. 



Southern, ^5-^S 't»s. 9.55 lbs. 



Northern field, i5-35 lbs. 9.05 lbs. 



Sanford, 13-65 lbs. 9.55 lbs. 



Pride of the North, 20.20 lbs. 11.80 lbs. 



So that while the per cent, of increase varied widely the act- 

 ual gain per hundred pounds was nearly identical in three of the 

 varieties. 



The followin ^ table shows the complete analyses of the four 

 varieties, as sampled September 16: 



From these figures we mriy compute the total amount 

 of each constituent produced per acre, obtaining the follow-

, If we accept the chemical composition as a true basis of 

 value the twelve and one half tons of Pride of the North would 

 be more valuable than the fifteen and one-third tons of Sanford, 

 and nearly as valuable as the sixteen tons of Northern field corn, 

 but no test that stops short of the feeding barn can be decisive, 

 and we will, therefore, defer all discussion of this point until a 

 subsequent " Bulletin on Feeding,"
