PEOM HOT WATER TO STEAM. 



"We are moving our greenhouses and 

 expect to change the beating system 

 from hot water to low-pressure steam. 

 There will be three houses, as follows: 

 North house, 20x100 and seven feet 

 high to the eaves; central and south 

 houses, each 25x125 and seven fe6t to 

 the eaves. The north house will require 

 a night temperature of 45 to 48 de- 

 grees; central house, 50 degrees; south 

 house, 55 to 60 degrees. We have a lot 

 of 2-inch pipe on hand and should like 

 to use it. How many runs of 2-inch 

 pipe will be needed in each house? The 

 houses will be connected. I am enclos- 

 ing a rough sketch of the houses. 



F. M.— la. 



The accompanying sketch shows the 

 office at one end of the 100-foot house 

 and the boiler room at the other end. 

 The other houses have both ends ex- 

 posed. 



While I would prefer to use 1^-inch 

 pipe for the returns, if the boiler is 

 sufficiently large it will be possible to 

 secure good results with 2-inch returns. 

 For the house 20x100, use one 2i^-inch 

 flow and four 2-inch returns for 48 de- 

 grees. For 50 degrees in the middle 

 house, 25x125, use one 2^-inch flow 

 and five 2-inch returns. In the other 

 house put in one flow and seven returns 

 for 60 degrees. 



THE FUEL MARKET. 



The coal trade is beginning to show 

 a few signs of returning life. In the 

 Chicago district many growers have 

 been taking in coal for several weeks 

 and other large consumers are doing 

 likewise, with the result that July was 

 a month of increasing activity, al- 

 though still subnormal. The market 

 prices have been sustained for months 

 only by curtailing production. August 

 2 the circular price for mine-run smoke- 

 less was advanced 15 cents, to $1.40 

 per ton, in accordance with custom; 

 there was no other circumstance to 

 warrant the advance. As a result of 

 the increased cost of smokeless coals, 

 which a few years ago were to be had 

 under $1 per ton, many growers in 

 the middle west have turned to Illinois 

 and Indiana coals, which can be had 

 today at $1.87 to $2.15 f. o. b. Chicago, 

 where the West Virginia coals cost 

 13.30 to $3.45. 



Consumers have felt that the condi- 

 tions this year made early buying un- 

 wise, but the producing interests have

Gentlemen: - 



Co. , 



Now that the firing season is oyer, 

 and after a long, cold winter, the 

 coldest night being 6° below zero, I 

 want to say I am well pleased with the 

 No. 46 WATER TUBE STEAM BOILER and the 

 No. 14 hot water boiler; they are doing 

 all you claim for them and more. 



The No. 14 hot water boiler heating 

 that large house to 62® with the great- 

 est ease in zero weather without the 

 help of the steam boiler. 



THIS STEAM BOILER I THINK IS A 

 WONDER, a quick steamer sind holds the 

 steam, the easiest boiler in the world 

 to cleaji and to keep clean. The double 

 steajn trap system is working fine, 

 keeping all the steam lines well drained. 



But the threaded boiler^ tube piping 

 system is the winner; the rapid circu- 

 lation and even temperature obtained 

 from this system is wonderful. 



After being told repeatedly by other 

 growers that roses could not be grown 

 with hot water heat, we are getting the 

 best kind of results not only from the 

 heating systems and boilers, but also 

 from the roses. 



Yours very truly, 



(Signed) W. J. PILCHER.
