42 MANUAL OF DAIRY CATTLE BREEDING 



Here is where the able salesman makes his money. Fill in two of 

 the pedigrees with the information to show the breeding worth of 

 the animal pedigreed. It is suggested that the first of these pedi- 

 grees be for one of the Advanced Registry animals and the other 

 for one of the random sample animals. Both of the pedigrees 

 should be presented in sales catalog style. Chapters IX to XXIV 

 of M. S. furnish information by which to evaluate the significance 

 of different sorts of ancestors' records in predicting the milk yield 

 or butter-fat percentage of a cow.

Sales catalogues of good companies furnish one of the best sources for models 



of how this work should be done.
