GUERNSEYS. 



Table II shows the influence of age on the values of four classes 

 of Guernsey cows, worth per head $80, $100, $200, and $300, respec- 

 tively, at three years of age. The estimates are classified as in Table 

 I. These figures, as compared with those in Table I, indicate that 

 appreciation and depreciation due to age are about the same for 

 Guernseys and Holsteins. According^ to these estimates, Guernsey 

 calves and old cows, like those of the Holsteins, are cheaper in the 

 East than in the Central West. In the case of pure breds in their 

 prime, however, the reverse is true. The estimates indicate that 

 Guernsey cows of all classes reach their highest value at 5 and 6 years 

 of age. (See fig. 2.)
