to carry 5 or 10 pounds on the

Greenhouse Heating. 



According to one greenhouse fireman, 

 the extortionate prices imposed by the 

 coal barons are not unmixed evil. "I 

 wish the stuff cost twice as much," he 

 says, "then a man would get a little 

 more credit for saving it." 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any detaUs of greenhouse heating that 

 are not understood. But please do not 

 ask The Eeview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment adverticed in this paper is, 

 we believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



THE WASTE IN SMOKE. 



"As to the common fallacy that 

 smoke necessarily represents a large 

 waste of fuel," says an expert in 

 Power, "a chimney may be smoking 

 badly and yet the amount of heat lost 

 by incomplete combustion may be neg- 

 ligible. The writer has tested the gases 

 at the base of a number of smoky 

 chimneys and has found that an aver- 

 age of one per cent of carbon monoxide 

 in the gases is seldona reached. As high 

 a percentage as this is only obtained 

 when there is little dilution with ex- 

 cess air and when the carbon dioxide 

 present is high, say, ten to twelve per 

 cent. Assuming the composition of the 

 fluk gases to be carbon dioxide (COj) 

 twelve per cent, carbon monoxide (CO) 

 one per cent, oxygen six per cent, ni- 

 trogen eighty-one per cent and the 

 calorific value of the fuel to be 12,500 

 B.t.u. per point, the heat lost by in- 

 complete combustion represents about 

 five per cent of the total available heat 

 in the fuel, which is much less than 

 many imagine." 



NO MOBE THIN PIPE. 



The so-called "standard" iron pipe 

 is a good deal thicker than it need be 

 for many purposes, especially in the 

 smaller diameters. Consequently it has 

 been the practice of the mills to draw 

 pipe to order of less than the standard 

 thickness for use under conditions in 

 which the standard pipe was not neces- 

 sary, and this pipe, of the same out- 

 side diameter as the standard, threaded 

 and coupled like it, similar, in every 

 particular except in thickness and 

 weight, has been known as "mer- 

 chanl" pipe. 



The reduction in weight per running 

 foot has been kept within limits and 

 the merchant pipe subjected to the 



Special Notice.

WHAT THE USERS S&Y 



ABOUT 



KROESCHELL BOILERS 



Cast Iron Boilers Break Down 



Hive fired greenhouse boilers since 1885, 

 botti steam and hot water. Yours soits taa 

 the be4t. I have two of your boilers. At one 

 time I had two cast Iron bollora worlcing 

 together, and during a blizzard the roar sec- 

 tion of one boiler save out and the front 

 aoctlon of the other spruns a crack a 

 couple of months later. No more CS4( iron 

 boilers for me. I came very close to freezing 

 out in both instances. 



G. M. TH08T. De Soto, Mo. 



Would Not Have a Cast Iron Boiler 



for a Gift, Since 1 Tried 



tbe Kroeschell 



The No f> Boiler is heating my entire range. 

 I believe it would take care of 18.000 square 

 feet. Have no trouble to keep temperatures 

 of 55 to tio degrees— I could keep 80 to 90 de- 

 gree* if I had to. During the coldest nights 

 I flred at 9. 12 and 3 o'clock. The boiler has 

 given entire satisfaction— in fact, more than 

 I expected. Previous to this I had a cast iron 

 boiler, but would not have it for a gift now 

 If I know of any one needing a good boiler I 

 shall recommend the Kroeschell Boiler above 

 all. JOHN LIErZAU, Geneva. 111. 



The Kroeschell does Our Work Easier 



Than Cast Iron Boilers and Saves 



Twenty to Twenty-five 



Per Cent Fuel 



The No. 4 Boiler is heating 10.000 square 

 feet of glass— it would take care of i:j,000 

 square feet easily. Havn no trouble to keep 

 temperature of 50 and 00 degrees in coldest 

 weather. The boiler has given perfect satis- 

 faction. We had two cast Iron boilers, one 

 rated for 1200 feet of pipe and one rated for 

 1.500 feet. These boHers never did the work 

 at their best and when the greenhouses were 

 new. According to our experience with yours 

 we will save twenty to twenty-flve per cent 

 of fuel. HILD BROS., Lake Forest, III. 



Try the Kroeschell First — It's Ahead 

 of Them All 



I have had eight or ten other types of 

 boilers. Tho Krooschell Is the best I have 

 over used. Your boiler heats the water very 

 quickly— almost as fast as steam. 

 Yours very truly.
