The report of Smith, Lineaweaver & 

 Co., Philadelphia, is unusually interest- 

 ing this month, foreshadowing, as it 

 does, the possibility of a shortage in 

 both anthracite and bituminous coals 

 doling the spring and early summer of 

 1912. 



"All the anthracite mines are run- 

 ning full time and have been for the 

 last few months. Tho demand is excel- 

 lent and prices strong. This is not at 

 all unusual at this time of the year. 

 Further, it is generally supposed that 

 there will be a strike in both the an- 

 thracite and bituminous coal regions 

 April 1, 1912, when the present agree- 

 ments with the mine workers expire. 

 This will have a tendency to create an 

 extraordinary demand through the win- 

 ter, as many people will desire to carry 

 heavier stocks, with prospect of labor 

 trouble, than they ordinarily would. 



"The bituminous coal demand is not 

 so strong as it ordinarily is at this time 

 of year, but is improving steadily. The 

 better grades are in rather active de- 

 mand and at good prices, while the low 

 grades are in only fair demand, but 

 show some slight improvement." 



THREE KANSAS HOUSES. 



I am building a house 11x75 feet, 

 five feet to thfl gutters and eight feet 

 to the ridgo, at the south side of my 

 present house. How many 2-inch re- 

 turns will be needed to heat it to 40 

 degrees when the outside temperature 

 is 3 degrees below zero? My present 

 house has one 2-inch flow and eight 

 li/^-inch returns pn each side; that is, 

 there are two 2inch flows and sixteen 

 lJ{.inch returns. I wish to change the 

 2-inch flows to 214-inch flows. 



My boiler is tapped for one 2i^-inch 

 flow and two 2-inch returns. It is a 

 twelve horse-power traction boiler, with 

 thirty-two 2-inch flues, and it holds 

 three or four barrels of water. Would 

 this boiler be large enough to heat 

 three houses, each seventy-five feet 

 long, with the other dimensions as fol- 

 lows: Eleven feet wide, five feet to 

 the gutters and eight feet to the ridge; 

 twenty-three feet wide, five feet to 

 the gutters and twelve feet to the 

 ridgo; thirty-two feet wide, five feet to 

 the gutters and twelve feet to the 

 ridge f B. P. M. 



For the first house described it will 

 be desirable to use one 2l^-inch flowand 

 four 2-inch returns. While one 2-inch 

 flow might be used, it would be rather 

 small for the best results. Ihe change 

 from 2-inch to 21,^ -inch flows in the 

 other house will certainly be a good 

 one, as it is not advisable to attempt 

 to carry more than 200 square feet of 

 radiation with a 2-inch flow pipe. 



A twelve horse-power boiler will 

 hardly be large enough to heat three i 

 houses of the sizes mentioned, unless it
