FEEDING ANIMALS. 



This experiment shows that the same law holds with 

 different weights of the same breed, as in different weights 

 of different breeds ; and that it is the natural effect of size 

 upon the food of support, and that this is probably in 

 proportion to the area of outside surface of the animal. 



In 1852, a series of experiments were made at 11 different 

 localities in the kingdom of Saxony, by order of the Royal 

 Agricultural Society, during a period of five years, the 

 cows selected being of the best " scrubs," Allgauers, Olden- 

 burgers, and Hollanders, the last two being really of the 

 same breed, the 'difference relating merely to the manage- 

 ment in different localities. The results, per annum, for 

 five years, were reported as follows : 



WITH COMMON FEED AND CARE. 



Scrub cows averaged 1,437 quarts per annum. 



Allgauers " 2,334 



Oldenburgers " 2,220 



Hollanders " 2,062 



WITH THE BEST OF FEED AND CARE. 



Scrub cows averaged 2,365 quarts per annum. 



Allgauers " 3,000 



Oldenburgers " 3,712 



Hollanders * , 



The scrub cows were much lighter than the others. 

 One dairy of Hollanders, of 190 cows, averaged 4,076 

 quarts per cow. These latter experiments seem to have 

 been undertaken principally to determine the breed of 

 cows producing the largest product, and these were found
