"It is as certain as any future thing 

 can be that there will be no substantial 

 reduction in freight rates on coal this 

 year. The railroads themselves are pay- 

 ing for coal prices per ton which, accord- 

 ing to the latest statistics available, 

 average $4.40 per ton, or about 180 per 

 cent higher than in 1916. The advances 

 in rates on coal have averaged nowhere 

 near this much, and the railways cannot 

 afford to reduce the rates on coal when 

 they are liaving to pay sucli high prices 

 for it. Furthermore, there seems no 

 prospect of any consi.leral)lc reductions 

 in prices of coal, because the mine opera- 

 tors are still ])aying the mine workers 

 the highest wages in history and under 

 their contracts will have to continue to 

 do so until April, 19213. 



"All the past warnings regarding the 

 increasing danger of coal troubles next 

 fall and winter have been disregarded 

 by the public. It is to be hoped that the 

 warninji;s now being given will receive 

 more attention." 



HEATING THE HOUSE. 



Will you advise me as to the size of 

 hot wator heater and the number of 

 2-inch pipes necessary to heat my green- 

 house, ;!2xl00 feet, of which I am send- 

 ing a sketch? House is to be kept at 

 a temperature of 65 degrees for one and 

 the other at 80. Occasionally we have 

 below-zero weather, but usually the cold- 

 est is around 30 degrees above zero.

It is not clear what is meant by 

 "House is to be kept at a temperature 

 of 65 degrees for one and the other at 

 80." It may be that one end of the 



house is to be heated to 65 degrees, while 

 the other is to have a temperature of 80 

 degrees, or, although only one house is 

 referred to, it is possible that there are 

 really two houses, of which one is to 

 have 65 degrees and the other 80 de- 

 grees. 



The sketch shows four feet of glass 

 and throe feet of concrete in the walls. 

 To heat such a house to 65 degrees, it 

 would be advisable to use six 2%-inch 

 flow pipes and twenty-two 2-inch re- 

 turns, with two flows on each plate, two 

 on the purlins and the others under the 

 ridge. The four outer coils could have 

 four returns each and the others three

returns. If one house is to be heated to 

 80 degrees, two additional flow pipes 

 and eight more returns will be needed. 

 In case one end of the house is to have 

 80 degrees, it would be well to cut it 

 off by means of a partition and to run 

 the additional flows and returns in the 

 boiler end of the house from the boiler 

 to the partition. 



A house 32x100 feet, with four feet 

 of glass in the walls, will require 1,800 

 square feet of radiation for 65 degrees 

 and 2,400 square feet for 80 degrees. 

 If one end of the house is to be heated 

 to 80 degrees there will be about 2,100 

 square feet of glass in the house. In
