Greenhouse Heating 



SxTBSCBiBEBS 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 capacity of boil- 

 ers, or tlie amount of radiation required 

 for a greenhouse, the needed temperatures 

 should be stated in the inqtiiry, as well 

 as the amount of glass in the side walls, 

 and the dimensions and general arrange- 

 ment of the greenheuses. It is often help- 

 ful, also, to have a sketch showing the 

 location of the houses. 



THE COAL MARKET. 



Production of bituminous coal con- 

 tinues to show signs of improvement. 

 The output of last week is estimated at 

 7,296,000 net tons, which represents a 

 gain over that of the week preceding of 

 ,S26,000 tons, or nearly five per cent. 

 While this tendency is a favorable one, 

 it is not pronounced enough to indicate 

 any building up of large reserves by in- 

 dustrial consumers, stated a leading 

 coal trade paper last week. 



Industry is not purchasing coal in 

 large quantities, and most of the activity 

 is in the form of inquiries rather than 

 actual sales. Eeports from one section 

 of the country indicating that industry 

 is reviving to some extent are more than 

 offset by others that factories in an- 

 other section have further reduced their 

 operations^ — a condition tliat is causing 

 industrial buving to remain at a low 

 ebb. 



Large buyers are not evincing any de- 

 sire to contract, but are preferring to 

 make their purchases on the open market 

 at prevailing spot prices. It is not 

 unlikely that they will not depart from 

 these tactics for" thirty or sixty days, 

 until the differential between spot and 

 contract quotations is more in their 

 favor. The possibility of lower freight 

 rates is also causing the consumers to 

 liold off from large purchases, although 

 it is possible that any reductions that 

 are made will not have their effect until 

 a car shortage has made coal so difficult 

 to move that a reduction in freight will 

 be less than the increase in the cost of 

 the coal at mines. 



Considerable apprehension is felt by 

 operators in general over the supply of 

 open-top equipment for transporting 

 coal in sufficient quantity to take care of 

 the demand which will assert itself when 

 large consumers of coal abandon their 

 waiting tactics. Coupled with the nor- 

 mal traffic in building supplies that this 

 type of equipment must handle is that of 

 coal, which promises to be abnormally 

 high. As only sixty per cent of this 

 rolling stock used in the transporting of 

 coal will be available, the shortage may 

 reach serious proportions. 



Last week the following prices were 

 quoted on bituminous coal in Chicago:

I have a small greenhouse. 10x1.'), 

 which I should like to heat to 55 de- 

 grees in zero weather. There are no 

 side walls and the eaves rest on a con- 

 crete foundation, le-^el with the surface.

READ WHAT THE USERt SAY: 



t'u«t Iron Cannot Be Compared 

 With Kroeschell. 



We bought a No. 2 Boiler. It takes 

 care of 5.000 sq. ft. of gla.ss, and we 

 could ad(l 2,000 more. We are very 

 well satisfied. We used a cast Iron 

 boiler before we had yours. It can- 

 not be compared wfth the Kroeschell 

 Boiler. Your boiler has certainly a 

 great capacity for heating water.

Cast Iron BoUerg Break Down. 



Have fired greenhouse boilers since 

 1885, both steam and hot water. Tours 

 suits me best. I have two of your 

 boilers. At one time I had two cast 

 iron boilers worliing together, and 

 during a blizzard the rear section of 

 one boiler gave out and the front 

 section of the other sprung a cracli a 

 couple of months later. No more cast 

 iron boilers for me. I came very ctose 

 to freezing out in both Instances.

Ca«t Iron Boiler Craclied In Two 

 Years. 



We have a No. 4 Kroeschell Boiler. 

 It tal^e.s care of 7.0(10 scj. ft. of glass; 

 it would talie care of twice thai 

 amount. 



I first had a new cast iron boiler, 

 which Ia«t«d two years, when it 

 cracked to pieces. The second was a 

 second-hand boiler. 



I consider your boiler the best pay- 

 ing investment I ever made. 



You can refer anyone to uh.

Cast Iron Boilers Cause Freeze-ont — 

 Kroeschell Boilers No Worry 



I bought a No. 2 Boiler. Takes care 

 of 7,000 sq. ft. of glass— ^would take 

 care of 2,000 more. I have had a 

 cast iron boiler, but It broke down 

 twice in four years, always in the 

 coldest weather. It broke down ii) 

 December, and I lost all my stock in 

 consequence. I have now two No. 2 

 and one No. 6 Kroeschell boilers and 

 do not worry about their breaking 

 down.

Kroeschell Versus Cast Iron. 



The No. 7 Boiler I bought from you 

 is heating 14.000 sq. ft. of glass; I 

 think it can take care of 1(5,000 sq. ft. 

 1 do not have any trouble to keep up 

 temperature of 50^ in the coldest 

 weather. I fire only once after 12 

 o'clock midnight. The boiler has given 

 perfect satisfaction. I have four cast 

 iron boilers — like the Kroeschell best 

 of all. if anyone wishes to inquire 

 atiout your boiler, let them write me, 

 for I think your boilers are good ones.

The Kroeschell Does Our Work Easier 

 Tlian Cast Iron Boilers and 



Saves 20 to 25% Fuel. 



The No 4 Boiler is heating 10.000 

 sq. ft. of glass — It would take care of 

 13.000 sq. ft. easy. Have no trouble 

 to keep temperatures of 60 and 60 

 degrees in coldest weather. The boiler 

 has given perfect satisfaction. We 

 had two cast iron boilers, one rated 

 for 1,200 ft. of pipe and one rated for 

 1.500 ft. These <2pilers never did the 

 work at their best and when the 

 greenhouses were new. According to 

 our experience with your^, we will 

 save 20 to 2570 of fuel.
