As these samples, from widely different localities, 

 are, without exception, much finer than the specimens 

 measured by Mr. Youatt, we may safely attribute the 

 change to the same causes that have produced the 

 modifications of form and feeding qualities that char- 

 acterize all of the improved breeds. 



The Kerry cattle of Ireland are a small and hardy 

 race. The scanty supply of coarse food obtained on 

 their native hills, by industrious efforts, gives a slow 

 growth and a late development of the organization, so 

 that the heifers, it is said, do not breed until six or 

 seven years old. 



Animals of this breed raised in Massachusetts, un- 

 der more favorable conditions for development, are 

 larger than the original type, and mature earlier, the 

 heifers breeding at the age of three years.
