Greenhinse Heating 



SuBSCRiBEBS are invited to write the 

 Editor of this Department with regard to 

 anj details of greenhouse heating that 

 are not understood. When information 

 is desired regarding the capacity of boil- 

 ers, or the amount of radiation required 

 for a greenhouse, the needed temperatures 

 should be stated in the inquiry, as well 

 as the amount of glass in the side walls, 

 and the dimensions and general arrange- 

 ment of the greenhouses. It is often help- 

 ful, also, to have a sketch showing the 

 location of the houses. 



FUEL SHORTAGE FELT NOW. 



Shortage of coal is already making 

 itself felt and by the time cold weather 

 sets in there will be a lack of fuel 

 which will create a serious situation in 

 this country, according to representa- 

 tives of the coal industry. 



Officials of coal companies say that 

 the outlook is distinctly unfavorable; 

 the demand already exceeds the supply 

 and will increase rapidly in the next 

 three months. Householders and fac- 

 tory owners who have not obtained 

 their supply for the winter are likely 

 to face difficulties in getting enough 

 for their needs. 



The output of bituminous coal can 

 be maintained at the proper level, it 

 is said, but not enough cars are avail- 

 able to move the coal from the mines. 

 As there are no facilities for storing 

 the surplus, the mines are compelled to 

 cut down production until they are fur- 

 nished with rolling stock. 



Among coal men it is asserted that a 

 large part of the shortage this winter 

 will be the result of failure of the pub- 

 lic to lay in supplies during the spring 

 and summer, when the mining companies 

 were begging for orders and were sell- 

 ing even below the cost of production 

 in order to keep their mines going. 

 Now the mines arc unable to supply the 

 demands, is the claim. 



The managing director of the Ameri- 

 can Wholesale Coal Association states 

 that the total possible production of coal 

 in the United States is about 675,000,- 

 000 tons bituminous, but that the actual 

 figures a year now reach about 585,000,- 

 000. He says that the maximum indi- 

 cated demand is about 137,000,000 in 

 excess of the production. The chief 

 reason for this he gives as the enforced 

 idleness of the mines from lack of 

 orders from the time of the armistice 

 until May and June of this year. There 

 is a crying need of coal for export to 

 Europe which cannot be filled, and the 

 shortage at home is likely to prove 

 serious. 



SIZE OF PIPE FOB HOUSES. 



I am building five greenhouses, three 

 of them 30x60 and two 12x60, with a 

 height of six feet to the gutters. Both 

 gable ends are exposed. The boiler and 

 sheds are on the north side. Would one 

 2-inch flow and two 1-inch returns under 

 each bench keep the temperature at 55 

 degrees during the night? The boiler 

 pit is four feet deep. I expect to use 

 steam and will install a trap. There is 

 no windbreak on either side.
