693. Herd record for one year. — We turn with interest to a 

 report of the Station herd at Cornell University, * where the cosi 

 of feed consumed and the returns from each cow in the herd, 

 twenty in number, are reported separately. When Prof. Eoberts 

 took charge of the herd in 1875 the yield of milk was 3,000 pounds 

 per cow; now descendants of these cows average more than 7,000 

 pounds of milk each. The prices allowed for feeding stuffs con- 

 sumed have already been stated. The returns from the twenty 

 cows are given in the following table:
