giving them a slight fall. At the far- 

 ther end drop the middle flow pipe 

 down to a point just below the level 

 of the plate, and with it feed six 2- 

 inch returns, three of which should run 

 either way, across the end of the house 

 and along the sides back to the heater. 

 Use each of the other flow pipes to feed 

 a coil of six 2-inch returns to run on 

 the side walls back to the heater. 



Keep all of the returns as high as 

 possible. Connect the return pipes to 

 the boiler either with one S^^-inch, two 

 3-inch or three 2%-inch pipes. There 

 should be gate valves on one-third of 

 the returns, at the higher end, so that 

 a part of the circulation can be cut off 

 in mild weather. 



If 11/4 -inch pipe must be used for a 

 part of the returns, substitute nine for 

 six of the 2-inch returns. 



TWO veoetabi;e houses. 



I am building two houses, each 20x 

 100, with twenty inches of glass in the 

 sides. They run north and south. 

 There are raised benches in one house, 

 but not in the other. The houses are 

 designed primarily for growing vege- 

 table plants in the spring, but I should 

 like to have sufficient heating capacity
