houses f We should like to know where 

 we could get the best burners and how 

 to install them. Is there any florist 

 that has used crude oil for fuel? 



F. B. 



Crude oil will be found a satisfactory 

 fuel for greenhouse heating, and al- 

 though at the prices named the oil 

 will be the more expensive fuel, when 

 the cost of firing is considered it may 

 be cheaper in the long run. If the 

 apparatus is properly installed and han- 

 dled, there will be no injurious effects 

 from using crude oil. Burners for the 

 use of oil can be secured from dealers 

 in Chicago and in all of the large cities 

 in the oil belt. 



PIPING FOE A LEAN-TO. 



Please give us some instructions 

 about the piping of a small lean-to 

 greenhouse, in connection with a heater 

 in the dining-room. We want a tem- 

 perature of 60 degrees in zero weather. 

 The greenhouse is 11x36 and runs east 

 and west. It is four feet high at the 

 low side and eight feet six inches to 

 the ridge. It is sheeted with 1-inch 

 boards and stripped on the inside. At 

 the north end is the coal shed. The 

 greenhouse is thus enclosed on three 

 sides. Our dining-room, at the south, 

 is 11x15, and is almost in a line with 

 the greenhouse, with only a shed be- 

 tween. 



We have a small hot water boiler, the 

 No. 62 Ideal, with a grate 24x36, out- 

 side measurement. Would you advise 

 us to put this boiler in the cellar and 

 let the smokestack run into the house 

 chimney? The cellar is seven feet deep
