energies of the system. Whether it will prove remuner- 

 ative to do so must be determined by the value of the 

 cows. With grade cows it would probably be unre- 

 munerative, but with pure-breds it may, in some in- 

 stances, be different. When cows fail to breed regu- 

 larly, unless of high value, the best thing to be done, 

 probably, is to dispose of them and to replace them with 

 others as soon as this may be practicable. Cows that 

 breed irregularly will lower the profits of a herd in 

 proportion as they are present, and the hazard also 

 exists that they may transmit the objectionable char- 

 acteristic, at least in some degree, to the progeny.
