other two houses are built ridge and 

 furrow, without partitions. The outer 

 walls consist of three feet of glass and 

 three feet of boards. A temperature of 

 50 degrees is desired when it is 10 de- 

 grees below zero outside. 



While 2M;-inch pipes would be pref- 

 erable for the flows and 2-inch for the 

 returns, it will answer if you install the 

 3-inch pipe now on hand for a part of 

 the flow pipes and the iVa-inch pipe as 

 returns, especially if it is necessary to 

 put on a mercury generator, as would 

 be advisable unless the boiler can be 

 dropped so that the grate will be at 

 least two feet below the lowest part of 

 the returns. 



For the new houses, run a 3-inch flow 

 on each of the side wall plates. For the 

 returns use in each house six 2-inch 

 pipes in a coil on the outer wall and 

 four IV^-inch and one 2-inch on the 

 inner walls. 



Although it is not possible to use 

 pipes for furnishing bottom heat when 

 the house has solid beds, it is often 

 worth while to run one or more pipes 

 either in the walks on the sides of the 

 beds or overhead. If this is desired, it 

 would be well to use as a flow pipe in 

 each house the 2-inch return now on 

 the inner wall and two of the 2-inch re- 

 turns now on the outer walls could be 

 arranged as returns on the sides of the 

 beds. 



With the boiler set at the ground 

 level or nearly so, the circulation will 

 be improved if these returns are on the 

 purlin posts over the beds. 



Whether generators are used or not, 

 the higher the returns as compared with
