the walk in the house is but two or three inches above that of the work- 

 room floor, on which the boiler stands, but the toj^s of the beds rise 

 several inches higher. This necessitated overhead heating entirely, 

 and gave insufticient fall for any system to work well. The pipe con- 

 tained numerous angles and was a decidedly diflicult series to heat. 

 The heater used was a small hot water boiler, known as the Novelty 

 Circulator, made by the Abram Cox Stove Co . , put up in sections and 

 not suitable for steam heating, for which purpose it should have been 

 provided with a steam dome and greater evaporating surface, while as 

 put up there is nothing but a short piece of four-inch pipe to take the 

 place of this. The general slope of the pipes was also better suited to 

 the flow of hot water, as generally recommended.

Diagram of the Apparatus. 



The boiler was placed in the work-room just outside the house to be 

 heated, but separated from it by a stone partition. The above engrav- 

 ing shows the relative positions of tlie series. Three risers are 

 taken from a horizontal pipe lying on top the steam dome at the top of 

 the boiler, and pass directly through the partition into the house. 



Riser C runs from this horizontal pipe, 4^ ft. east horizontally into the 

 house, then rises 6 in., then rises obliquety 6 ft. 10 in., passing to 

 northwest corner, eastward 26 ft., near the roof with slight rise to 

 opposite end, then falls 3^ feet verticalh^ downward. Connected with 

 this is a lower loop, D, starting 6 in. from the northwest corner, which 

 drops vertically 3 ft. 6 in., then extends 25 ft. 9 in. eastward to the 

 perpendicular drop just mentioned, entering it 4 in. above the bottom.
