The great mass of butter records in advanced Registry are for periods of 

 seven consecutive days of twenty-four hours each. As classified March 1, 1897, 

 they are as follows : 



Of cows in full-age-form, 299.

Of the total number of records, one hundred and fifty-one are official. 

 These have been under exceedingly strict supervision of disinterested men 

 mainly from our State Experiment Stations. As classified they are as follows : 



Of cows in full-age-form, 49. 



u tt tt four-year-form, 28. 



" " "three-year-old form, 18. 



" u " two-year-old-form, 40.

These figures are worthy of careful study. They reveal the capacity of a 

 large class of our cows. The closeness with which the two divisions of records 

 approach each other is surprising. The difference between the average records 

 of full-age cows in these two divisions is only six and four-tenths ounces; 

 that between cows from four to five years old is four and seven-tenths 

 ounces ; while that between heifers from two to three years old is two arid 

 seven-tenths ounces. In the other two ages there is a wider difference, 

 by no means excessive. It does not follow that every record from which 

 these averages are calculated is reliable. One of the vital principles of 

 our system of Advanced Registry is that every record rests upon individ- 

 ual separate testimony. While the association inflicts the severest penalties
