82 How TO Grow Cdt Flowers. 



is what it was. Leaves are the lungs of the plant. 

 When they become diseased you have a case of vege- 

 table consumption on your hands. 



Quite a majority of the larger growers are located 

 outside of cities, and are thus obliged to provide water 

 works of their own. To obtain the required pressure 

 it is customary to raise the water to tanks varying in 

 height from fifteen to twenty-five feet. This renders 

 it comparatively easy to so arrange as to be able to keep 

 the water at an even and desired temperature. If con- 

 venient to do so, a separate flow and return can be 

 provided between the boiler and tank, or if steam heat- 

 ing is used, a coil of pipe in the tank can be used. The 

 use of a coil will be found the more agreeable way, 

 turning the end of the coil so the steam, after passing 

 through it, shall be discharged near the bottom of the 

 tank, as the noise from turning a jet of steam directly 

 Into the water is objectionable. If the coil is of suffi- 

 cient length, the heat will all be absorbed before the 

 jet reaches the discharge, and all noise thus be avoided. 



If your boiler is not able to do this extra work, by 

 all means provide a special one for the purpose. For 

 this, a hot water heater of some kind will require the 

 least attention, being very easily regulated. The ar- 

 rangement is the most simple possible. After setting 

 the boiler, presumablj'^ in the enclosure under the tank, 

 attach the flow and return to the bottom of whatever 

 contains your water supply, and it is ready for use. For
