150 PRINCIPLES OF STOCK-BREEDING. 



" The evidence of success in resorting to the practice 

 of in-breeding is too strong to be gainsaid." l 



The pedigree of Goldsmith's Maid, the " queen of 

 the American turf," is given in Diagram 5, as an illus- 

 tration of a well-bred trotter, as it includes several 

 other noted pedigrees. 



Sheep-breeders have quite generally practised in- 

 and-in breeding with the best results. 



The merino sheep, bred by the late Edwin Ham- 

 mond, present a remarkable example of close breed- 

 ing. " They were bred in-and-in by Colonel Hum- 

 phreys up to the period of Mr. Atwood's purchase ; 

 Mr. Atwood bred his entire flock from one ewe, and 

 never used any but pure Humphreys rams ; Mr. Ham- 

 mond has preserved the same blood entirely intact, 

 and thus, after being drawn beyond all doubt from an 

 unmixed Spanish Cabana, they have been bred in-and- 

 in, in the United States, for upward of sixty years." a 



The pedigree of the ram Gold Drop, for which 

 Mr. Hammond refused twenty-five thousand dollars, 

 is given in Diagram 6, in convenient form for study. 

 Dividing the " blood" of Gold Drop into 512 parts, it 

 would be made up as follows :
