be placed on each side wall. The flows 

 can be run on the walls just below, and 

 at the same slope as the plate itself, 

 and the returns can be placed under- 

 neath, starting at the farther end, 

 just below the flows, if care is taken to 

 grade them carefully and support them 

 at frequent intervals so that there will 

 be no pockets for air. It will answer 

 if they are given a slope of one inch 

 in thirty feet. 



If bottom heat is desired for the 

 benches, two flows and two returns 

 can be placed upon each of the side 

 walls and a 2^^-inch flow can be run 

 under the ridge. At the east end of 

 each house, a 2-inch supply pipe can 

 be taken off, which, after dropping 

 below the beds, can feed a coil of six 

 2-iucb pipes running the length of the 

 respective houses under the benches. 

 At the west end of each of these coils, 

 a 2-iuch return can connect the coils 

 with the main return underneath. This 

 should be 2y:.-inch from the point 

 wliere the second coil joins, to the 

 boiler. 



For the house 9x100 feet, a similar 

 arrangement can be used, except that 

 only one 2-incli flow and two 2-inch 

 returns upon each wall will be required.

 30 feet, eight feet from floor to ridge, 

 and Las 3-foot double boarded walls, 

 with glass in the south end. The house 

 runs north and south and slopes south 

 with the ground. The boiler will be 

 placed at the north end. I shall heat 

 with hot water and shall want a tem- 

 perature of 45 to 50 degrees in zero 

 weather. The boiler is tapped for a 

 2 VI' -inch flow. W. M. 



It will be possible to secure the heat 

 required by the use of two 2-inch flow
