HOW OTHER PEOPLE HAVE SUCCEEDED 15 



had a number of one-inch holes along its 

 bottom edges for circulation, and a sliding 

 door for access to the stove. Its top was 

 drawn up to form a collar about eight inches 

 in diameter. From this collar an eight- 

 inch flue ran up and out through the cellar 

 window (from which a pane had been 

 removed), and ended at a five by seven inch 

 register set into the floor of the "con- 

 servatory." The flue was enclosed in a 

 wooden box or outer flue for insulation 

 throughout its entire length outdoors. 



This formed virtually a miniature hot- 

 air furnace. The tiniest flame warmed the 

 stove, which in turn warmed the air enclosed 

 in the galvanized hood. This warm air 

 flowed up the pipe through the register and 

 gave the plants just what they needed — 

 pure, moist, warm air. 



HEATING FROM THE LIVING ROOM 



But it may not be possible always to instal 

 a carefully designed heating plant, and many 

 are the cases where satisfactory window 

 gardens are maintained by the heat from 

 the adjoining room alone — no extra appara- 

 tus — but of course no real forcing is done
