son, they were fed a limited quantity of grain, but were all 

 treated exactly alike in that respect. Thus we have the op- 

 portunity to ascertain whether these different feeds have any 

 residual effect, or whether the amount of gain made in winter 

 affects the gain to be made at grass during the following 

 summer. 



These cattle were weighed five days in succession before 

 being turned to grass in the spring, and were weighed on five 

 successive days when brought to the sheds in the fall. The 

 difference in these is considered to be the gain in weight at 

 pasture. The following table shows the gains made in sum- 

 mer in relation to the gains of the previous winter, ranked in 

 the order of winter gains: 



TABLE 17 



It will be noted that in general the larger the gain in 

 winter, the less the gain the following summer on grass. 



Considering the three lots having equal quantities of 

 grain and different roughnesses, their summer gains are in 

 inverse ratio to their previous winter gains. This means that 

 the thinner the animal in the spring, provided it be strong 

 enough to graze well, the greater the gain it is capable of 

 making at grass during the summer. Conversely, the fatter 

 the animal, the less capacity it has for making large gains on 

 grass. That this will be true of fat animals is self-evident. 

 It is easy to conceive of animals going to grass so fat from 

 having been grain fed for a considerable length of time that
