Greenhouse Heating 



3UBS0RIBERS are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. When information 

 is desired regarding the capacitj 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. 



SENATE AIRS COAL TROUBLE. 



In its investigation of the increased 

 price of coal, a senate interstate com- 

 merce subcommittee has brought forth 

 testimony that a shortage of cars and 

 labor difficulties is hindering coal pro- 

 duction, that certain elements in the 

 miners' union are intent on nationaliza- 

 tion of the coal mines, with the adoption 

 of a 6-hour day and a 5-day week, plus 

 a wage increase, and that unless prob- 

 lems of production are solved the coun- 

 try will be brought face to face with a 

 coal famine in the coming winter. 



After detailing the effects of labor 

 difficulties and car shortage on coal pro- 

 duction, Harry N. Taylor, president of 

 the National Coal Association, an or- 

 ganization of operators, declared a bill 

 had been prepared for submission to 

 Congress providing for the nationaliza- 

 tion of the mines. Ho added that what 

 the miners wanted was not only that 

 the government should own the proper- 

 ties but that the mines should be turned 

 over to them for operation. He insisted 

 that the more radical of the miners ap- 

 pear to be gaining control in certain 

 districts and that tlioro was a serious 

 danger that these clenionts would make 

 an earnest effort for the institution of 

 something approaching Soviet methods 

 in conducting the properties. Such 

 radical elements nre now creating diffi- 

 culties by strikes in various coal fields, 

 unauthorized by the union officials. 



The car shortage has appeared so 

 serious a matter that the coal price hear- 

 ing may be converted into a railroad 

 efficiency investigation. 



RAISING THE FLUE. 



How much rise shall I give a flue 

 forty-eight feet in length, with an inside 

 diameter of eight inchest It is fire- 

 proofed with tile and runs to a smoke- 

 stack at the end of the house. Would 

 It be better to run the flue back to the 

 smokestack on the furnace to get a 

 good draft t 8. G. W.— Kan. 



Everything else being equal, the 

 faster the flue rises the better will be 

 the draft. Hence, we should start the 

 flue as low as possible and at the other 

 end carry it as near the bottom of the 

 bench as can be done with safety. The 

 danger from fire will be greatly lessened 

 if the bench bottom and all the sup- 

 ports are constructed of cement. We 

 should prefer to have the flue rise at 

 least one inch in five feet, and would 

 • make it more if possible. We should 

 advise a rise of ten to fifteen inches 

 in a house forty-eight feet long. 



While there is some advantage in 

 carrying the flue back to the furnace, 

 the rise can only be one-half as much 

 as when it leads to a chimney at the

Expressions From Hen Wko Kuw Boilers 



Get the Kreetchell Futt 



Several years ago Mr. 



corresponded with us In regard to 



the Kroeschell Hot Water Boiler, but was persuaded to Install two 

 sectional cast Iron boilers which were claimed to be superior to the 

 Kroeschell. 



In the meantime we placed a number of Kroeschell Boilers In the 



Immediate vicinity of Mr. , and he could not help but notice 



their great efficiency, and last year, while at the convention, he 

 Iilaced his order for his flrst Kroeschell. The following letter speaks 

 for Itself: 



"We like the Kroeschell Roller very much. It gives entire satis- 

 faction, and it Ih ho caHy to Are. I will trade yon the two cast Iron 

 sectional boilers for another like the Kroeschell I have." 



[Signed] Mr. , Ohio.

Ni More Cast Inn B«ilen 



I have used several different 

 makea of boilers but none I like as 

 well as yours. 



The Kroeschell Is easier to Are, 

 takes less coal and water circulates 

 quicker than any other boiler. 



I have used two different makes 

 of sectional boilers — no more cast 

 Iron boilers for ns. 



[Signed] Mr. . Mich. 



Kraeschell Replaces Cast Iran ; 



The Kroeschell has replaced three 

 cast Iron sectional boilers, and It 

 certainly has given entire satisfac- 

 tion. 



It only takes a few words to ex- 

 press the good quality of your boil- 

 ers and they are as follows: "Of 

 all Arms handling boilers and ad- 

 vertising them truthfully, the party 

 buying a boiler would have to get 

 the Kroeschell, as you are certainly 

 advertising nothing but facU." 



[Signed] Mr. . N. T.
