WATER AND ICE SUPPLY 279 



Where the source of ice is at too great a distance from 

 the dairy, an artificial pond should be made upon ground 

 with a reasonably impervious subsoil and with a natural 

 concave formation. If such a piece of ground is flooded 

 with water during the coldest weather, an ample supply 

 of ice will be available in a very short time.
