lar or cow side in crossing, from increase of muscle and its 

 contained flavors and juices in the meat. And all grades 

 of Short-horns, as well as full-blooded animals, will in- 

 crease their fertility, and improve their meat quality as 

 ihey increase their exercise, muscle, and vital circulation. 



The grades of the Channel Island or Lawn cattle, as 

 already shown, gain 25 per cent in muscle, and almost as 

 much in quantity of blood and in vigor, from a cross of 

 the Devon on this slender-muscled family, the Jerseys and 

 Guernseys. But if Jersey bulls are used on common cows, 

 the grade will have 20 per cent /ess muscle than our com- 

 mon cattle, and 20 per cent more muscle than the pure 

 bred Channel-Islanders. And there is not a single breed 

 of cattle — not even the petted families of Short-horns — 

 but must have their grades deteriorated as to vigor, mus- 

 cularity, digestive power, and fertility, by crossing with 

 Jerseys or Guernseys, the reduction of muscle from such 

 crossing, impairing digestive power, and capacity for a^ 

 tivity beyond peradventure. 



Milk cows, like the Ayrshires, that have become slender 

 in their muscles, need crossing with more muscular stock, 

 like the Galloways or Devons, as an increase in muscular 

 proportion would " infuse " greater vigor into them, while 

 their digestive power would certainly be strengthened by 

 the acquisition of more muscle. This would not change 

 their form, otherwise than to round it out, so improving 

 it, nor reduce , their _milk--y-ieldiag,.capacity^' The Jerseys ■ 

 are also much in need of increased muscle to augment their 

 vigor, and strengthen their breeding, capacity, and digest- 

 ive power. 



It will be remembered that Messrs. Colling and Bates, 

 the noted Short-horn breeders, were both shrewd enough to 

 acquire muscle, when they thought it would invigorate, by 

 resorting to more muscular cattle for infusion of new blood, 

 and increase in the extent of blood circulation. And it
