THE JERSEY, ALDERNEY AND GUERNSEY COW. 53 



toneued calves, and white- tono^ued bulls be^et black- 

 tongued calves (die dams being of the same color in 

 both cases), the evidence essential to uphold the theory 

 seems to be wanting. 



" It has been also suggested that this essay should 

 include a treatise on the management of Jersey cows. 

 Except with reference to their breeding, there seems to 

 be no necessity for treatment different from that which 

 all cows require, and to introduce a comprehensive 

 article on dairy farming would be unnecessary, and 

 would add too much to the size of the Register. 



" If this breed has any peculiarity that requires 

 special care, it is the persistence with which its better 

 specimens hold out with their milk while pregnant. 

 This tendency is surely to be encouraged within reason- 

 able limits. If a cow can be made to yield a fair flow 

 of milk up to within four weeks of her calving- time, 

 and need go absolutely dry but two weeks, there is no 

 question of the advantage of her doing so. That she 

 should milk up to the very day of calving indicates cer- 

 tainly a good milk-making tendency ; but it is at least 

 not proven that such constant milking is not injurious. 

 Persistent milkinor is a characteristic merit of the better 

 class of Jersey cows, and it is of immense advantage, 

 not only in the case of a single family cow, but in those 

 used for the butter dairy. It is in all respects better 

 that a cow should commence her flow at lo quarts and 

 not fall below 5 quarts a month before calving, than 

 that she should give 20 quarts the first month, 10 quarts
