slight roof like pitch on the top, at the apex of which a cylinder 
five inches long was soldered to connect a coil of lead pipe which 
acted as a chimney, to assist the draft of the oil stove as well as 
to help distribute the heat. After prepared for use, the water box 
(see cut) could be set down over an ordinary oil stove of three or 
four burners. In practice the box was set up from the cement 
floor on blocks high enough to allow removal of the stove for 
filling and trimming, after which it was slid back and raised up to 
' place where it was held by a board resting on blocks. 
This arrangement worked so well that it was utilized to warm 
milk for calves and food for pigs in addition to this experiment, 
and proved to be very cheap heat for these purposes.
