means of two 2% -inch flow pipes and 

 six 2-inch returns. 



To heat the houses with steam, run 

 a 2%-inch flow pipe about three feet 

 below the ridge of each of the wide 

 houses and a 2-inch pipe in the narrow 

 house. In the wide houses use eight 

 1%-inch returns, arranged in coils un- 

 der the benches. Five returns only will 

 be needed in the narrow house, of which 

 three should be on the north wall.

 waterproof pit for a hot water boiler? 

 We wish to lower our boiler two feet 

 more, which will place it below the 

 high-water level of a near-by well.

The side walls of the pit may be con-

 or a form may be constructed, back 

 of which an 8-inch wall of concrete 

 should be built. The bottom of the 

 pit should be a 4-inch layer of con- 

 crete. Use one part of cement to four 

 of sand for laying the blocks, and add 

 to this four parts of coarse gravel or 

 crushed stone for building the floor of 

 the pit and the walls, if they are built 

 of concrete. For the inside coat on the 

 ■walls and floor, use one part of cement 

 to two of sharp sand, making the finish- 

 ing coat three-eighths of an inch thick. 

 Apply this before the walls have set or 

 wet them down thoroughly before plas- 

 tering. In case the wall sets and turns
