It is needless to explain the bad effects, upon the depurative or- 

 gans of the derangement of the circulation by which these channels 

 are to a greater or less degree " clogged," or unable to do their 

 proper work. , 



Now, it is within the province of every owner to prevent these 

 troubles by employing care in feeding, exercise, etc., which is 

 much better and easier than to try to cure them when sick. It is 

 far easier to prevent a house from getting burned up by not letting 

 the fire get started, than to depend upon the power of putting it out, 

 for with the best of energy it may cause a destruction of the build-
