quarterly parts, since 1895, as the American Guernsey Herd 

 Register arid Breeders' Journal. The American club also main- 

 tains an advanced register. Bulls are admitted in two classes : 

 (a) after scaling 80 points and having two daughters in the 

 register ; and (b) without scaling, after two daughters are regis-

 records and scaling over 75 points ; and (b) for milk or fat records

 for the largest official butter-fat test in one year. During 12 months end-

without scaling. The cows must produce from the first day of 

 two years of age, or before, at least 6000 pounds of milk, and 

 this is scaled up to a minimum of 10,000 pounds for cows five 

 years old or over. So the year's butter-fat record must have a 

 minimum of 250.5 pounds at two years, and 360 for over five. 

 Seven-day fat tests are also provided for. The tests for advanced 

 registry are supervised by agricultural college or experiment 

 station experts.
