RECORDS 55 



sources wonderful performances have been reported. Though 

 they were held to be questionable at the time, many, if not all, 

 have since been equalled by animals working under official 

 supervision. 



The Advanced Registry system Avas begun by the Holstein 

 breeders, and Mr. S. Hoxie, of Yorkville, New York, should be 

 given the credit for having developed the system by which the 

 various State Experiment Stations and Agricultural Colleges 

 are now authorized to send out official testers to verify the 

 records made. This association was the first to adopt the Bab- 

 eock test as the official method of determining the fat. This 

 was done in 1894. While at first the records were reported 

 in terms of butter at SO per cent fat, the rules were later modified 

 so that the official reports now are upon the basis of fat only. 

 To convert the quantity of fat to butter equivalent it has been 

 customary to add one-sixth of the fat to the fat. In the study 

 of any pedigree note should be made as to whether the records 

 are in terms of fat or in terms of butter, and whether the butter 

 was figured on the basis of 80 or of 85 per cent fat. 



The minimum requirements for the admittance of a Holstein 

 to advanced registry are as follows : 



2 years old 7.2 pounds of fat in 7 days. 



3 years old S.8 pounds of fat in 7 days. 



4 years old 10.4 pounds of fat in 7 days. 



5 years old 12.0 pounds of fat in 7 days. 



These requirements were established when cows were not as 

 well fed nor as skillfully handled as now. The question may 

 well be raised whether the requirements for admission should 

 not now be raised. This would seem evident from the number 

 of animals capable of passing the advanced standing, and the 

 fact that a number of animals have more than doubled the re- 

 quirements. The animals standing highest in the seven-day 

 records up to January 1, 1921, were as follows:
