pools of filthy liquid, and even moist contents, is one of the 

 very best materials with which to generate autumnal fevers, 

 diarrhoea, dysentery, and this class of diseases. And if the 

 farmer could be sure to see to it that, once each day, all the 

 barn-yard and pigpen waste is thoroughly covered with dry 

 earth during the dangerous months, we are willing to insure 

 much less of paying the doctor, and a cleaner bill of health 

 all around. And could I also impress the fact of the money 

 advantage in thus saving the ammonia of his manure, I 

 am sure the physician and the physiologist have done their 

 duty.
