 not so much, may be expected. In a publication of the American

Guernsey Cattle Club on "the Grade Guernsey Cow" much in- 

 teresting evidence is brought forward. L. E. Bronson, referring 

 to five years' work in grading up, states that since following this 

 practice of grading to the Guernsey, the yearly yield of the herd 

 has increased over loo pounds butter fat per cow. N. I. Bowditch 

 of Massachusetts, a long-time Guernsey breeder, writes : 



I am glad to be able to write you that this cross has been very satisfactory, 

 especially so the first cross with Holsteins. I have bred several Holstein cows 

 that tested from 2.8 to 3.4 butter fat, and their progeny have given me milk 

 testing all the way from 4.5 to 5.6. I have crossed the Guernsey bull with
