DOMESTICATED RACES OF CATTLE. 3 



(3) Yet others regard them as the result from crossing 

 these. 



(4) The second theory is more likely to be correct, since 

 improved environment is followed by improved development. 



VIII. Nearly all the improved breeds of cat- 

 tle found in Anglo-Saxon speaking countries have 

 been derived from Great Britain, because 



(1) Of the great variety and superior excellence of the 

 breeds found there, and 



(2) Of the natural genius of her people for stock keeping 

 a characteristic which the colonists have carried along 

 with them. 



IX. In many of the older countries of the 

 Eastern world the cattle are probably descended 

 from an ancestry going far back beyond the Chris- 

 tian era. 



(1) They have not improved because agriculture has not 

 materially improved, and 



(2) This is more particularly true of pastoral countries. 



X. Nature unaided can in suitable localities 

 maintain a certain standard of excellence through 

 the laws that govern natural selection, but she can- 

 not improve upon these, hence 



(1) Domestication is necessary to effect improvement, but 



(2) It does not follow, of necessity, that domestication 

 always improves upon nature.
