own horse and wagon as some farmers prefer to board both man 

 and horse, rather than to hitch up and drive from one to four 

 miles to the next farm.

3. Official Testing of Dairy Cows. 



149. Weighing and testing the milk of each cow at the farm 

 by the owner or by an employee of a Cow Testing Association as 

 already described are done for the purpose of "weeding out the un- 

 profitable cows." There are at the present time, however, two other 

 systems of testing cows that are carried on for the purpose of ob- 

 taining an official statement of cow's milk and butter fat produc- 

 tion, in order that such a record if exceptionally high may help to 

 obtain an increased price for the cow and her offspring. In this 

 way the owner may dispose of his surplus stock at good prices. 

 One of these systems of testing cows is known either as the Ad- 

 vanced Registry or the Authenticated Tests, and the other as the 

 Dairy COAV Competition. 



150. In 1894, the American Holstein-Friesian Association es- 

 tablished what was called- the "Advanced Registry," or a class 

 which included cows that had reached a .certain standard of milk 

 and butter production in tests supervised by a representative of an 

 Agricultural College or an Experiment Station and conducted ac- 

 cording to certain regulations. This same general idea was taken 

 up by the Guernsey Cattle Club in 1901, and by the Jersey Cattle 

 Club in 1903. The tests recognized by these various associations 

 are confined to pure breed cows. Rules for making such tests as 

 well as directions to be followed by the man supervising them are 

 printed; and there has been a constantly increasing number of 

 such tests made each year since the work was started.
