perature of the -water to 10,6^ is SSlbs. In twelve 

 hours the water cools, after the fire has been ex- 

 tmgiiished, from 125° to 93°. 



"WTien steam is employed, the space for steam in 

 the boiler is easily found by multiplying the length 

 of the pipe in feet, by the quantity of steam in 

 a foot in length of the pipe.

In the above noticed house the length of pipe, 

 5 inches in diameter, is 150 feet, and these mul- 

 tiplied by 1.363=20.5 cubic feet of steam; and as 

 the pipe will condense the steam of about one cubic 

 foot and one third of water per hour, therefore the 

 boiler should be capable of evaporating 1| cubic feet
