hose of good quality with heavy wall, but

sold by different dealers at prices ranging

are suitable for use among vegetables, shrub¬

that water and 
kerosene may 
be applied 
mixed without 
the trouble of 
making an 
emulsion. This 
pump is manu¬ 
factured by Leg¬ 
gett & Brother, 
New York City.
