lactation period. She appears in Table II as No. 105 with 5*9% of 

 butterfat. 



In considering the facts disclosed in these tables, it has to be 

 remembered that all our beef breeds are inbred. But as the qualities 

 required are as often seen in the female as in the male, both sides are 

 bred to. I append on p. 90 the pedigree (VII) of the first noteworthy 

 shorthorn bull as a sample of breeding for beef It causes me no 

 surprise that highly bred shorthorns are notoriously deficient in milk. 

 Mr Taylor produced a well-known herd of " milking shorthorns " and 

 his pedigrees show inbreeding to male relationships. 



The Jersey herd book is full of pedigrees inbred to the male though 

 there is a tendency to use full relationships. 



In conclusion, I think that the results here set out afford prima 

 facie evidence of the direction of future breeding for an increase in milk 

 production.
