 and Barb, I have said, are the foundation in 

 blood of all the great types from the Percheron to 

 the Thoroughbred. To be sure, other and dissim- 

 ilar blood was used in the beginning of the mak- 

 ing of all the types, but there was such crossing 

 and recrossing, such grading up by a selection of 

 mates, that the blood became similar, and the 

 rule : " Like begets like," being constantly follow- 

 ed a type becomes established. 



When a type has been established and is of un- 

 questioned value to the world, it should be pre-
