AVERAGE QUANTITY OF COAL. 



What would be considered a fair quan- 

 tity of coal to cotBume in heating a well 

 built greenhouse, 3.2x206 feet, to carna- 

 tion temperature in northern Ohio for a 

 season, figuring on average winter 

 weather? A good grade of lump coal 

 would be used, with plenty of boiler 

 capacity and a good system of hot water 

 piping. C. B. 



So much depends upon the boiler and 

 the skill of the fireman, as well as the 

 eflSciency of the piping, the quality of 

 the coal and the character of the 

 weather, that all that can be given will 

 be the merest approximation, but under 

 favorable conditions it should be possible 

 to maintain the temperature stated with 

 400 pounds of coal per day, as an aver- 

 age through the season. In severe weather 

 it might be twice the quantity mentioned, 

 but 600 pounds is morely likely to be a 

 maximum. On the basis of 400 pounds 

 as an average and 180 days in which a 

 fire must be maintained, it will require 

 thirty-six tons of lump coal in a season. 



SCALE IN BOILER. 



Will you please tell me how to prevent 

 my greenhouse water from getting limy? 

 It is hard water. I have a hot water 

 boiler, which heats 15,000 square feet of 

 glass. I have only one tank, a large one, 

 which is used both for the boiler and for 

 watering. Will it cause any injury to my 

 plants if I put something in the water to 

 prevent its being so hardf J. P. M. 



I infer that this question really relates 

 to preventing "scale" from being de- 

 posited in the boiler. While there is 

 often considerable trouble from this when 

 hard water is used in steam boilers, the 

 amount deposited in a hot water boiler 

 is generally so small as to be of little 

 account. It would hardly be safe to use 

 the water in the tank for watering the 

 plants, if * ' boiler compound ' ' were used.

and it hardly seems possible that any 

 such remedy will be necessary. Bather 

 than go to the trouble and expense of 

 putting in an expansion tank, which 

 would be necessary if a scale preventive 

 is to be used, it will be easier to draw the 

 water out of the system once or twice 

 during the winter. This will prevent the 

 lime being deposited, as it will only take 

 place when the water has become sur- 

 charged with lime, owing to evaporation. 



UNSATISFACTORY PIPING. 



We have a greenhouse 19x90 feet, 

 eleven feet high to the ridge and run- 

 ning east and west. It is divided into 

 three rooms. In the smallest one we grow 

 chrysanthemums; the center room is de- 

 voted to roses and the one farthest from 

 the boiler is used for carnations. The 

 house is heated by a Hitchings No. 16 

 boiler. It is a good, air-tight house, built 

 by the Lord & Burnham Co. five years 

 ago, but we cannot keep the temperature 

 up. I make up my fire about 9:30 p. m., 

 with the rose house temperature about 56 

 degrees and the carnation temperature
