Two Men -^T wo Pieces of Iron— Two Boilers 



Dins ad. is solely for the man who 

 has 30,000 square feet of Klass or 

 less. It has to do with the ciiies- 

 tlon — "Which is best, a wroufiM iron 

 tubular boiler or a cast iron, scctioiml 

 onet" 



Before getting into the discussion, let 

 us right at the start make a fair and 

 square statement. 



Only for ranges above .'{0,000 square 

 feet of glass does the wrought Iron l)oller 

 become economical. For ranges up to 

 iind below 30,000 feet, the Burnham Cast 

 Iron Sectional Boiler has been i>roven 

 over and over again to be decidedly the 

 most economical. 



Cast iron conveys the heat directly 

 through it, into the water, much more 

 rapidly than wrought Iron. To prove 

 this fact to be a fact, we took a piece 

 of each kind of Iron, two feet long, one 

 loot wide, and a quarter of an inch 

 thick. These were held over two alco- 

 liol lamps having exactly the same sli!(^ 

 wick and llanu'. In !,"» seconds the 



wrought iron plate was so hot at itg. 

 fdf/i'K that it had to be dropped, while 

 the cast Iron one was excessively hot 

 ili recti If over the ^anw-, and the edges 

 still not at all uncomfortable to hold. 



Tills simple little experiment showed 

 iM-yond all argument that wi'ought Iron 

 lirst conveys the heat along itn nurfacc 

 l)ef()re It go(S through it. while cast 

 iron instantly transmits the heat di- 

 rectly through It, where the heat is ap- 

 plied. .Ml of which explains exactly 

 why Cast Iron Boilers heat up mor<! 

 (;iilckly than wrought Iron. Also, why 

 when once heated. It takes less to keep 

 them heated. 



So much for the heat conveying side 

 --now for the lasting qualities. 



If you put a piece of wrought iron 

 under a powerful magnlfyln'fe glass, you 

 would hee that its formation is In long 

 shreds quite like a Shredded Wheat Bis- 

 cuit. It Is plain to see that rust will 

 liavi- an easy time attacking, and quickly 

 I'Mting into, such Iron. 



Now look at the cast iron and you 

 will find it is such a compact mass of 

 closely lifted granules, that it is next to 

 Impossible for the rust to get down into 

 the metaL Which, in turn, accounts 

 for the fact that cast iron will scale 

 over only slightly with a thin film of 

 rust and then stay that way for years 

 and years. 



Now you see why wrought Iron boil- 

 ers rust out so soon. And why they 

 must be rctubed so often at such an 

 expense. 



You must now freely admit that the 

 arguments arc on the side of the cast 

 iron boiler. 



But all cast iron boilers are not 

 greenhouse boilers. 



The only cast iron boiler made cspe- 

 ri.Mlly for greenhouse work is The Burn- 

 liam. 



So the next thing for yon to decide 

 is— do you want "just a cast Iron boll- 

 • T." or a rant iron ijrecnhouse boiler, 

 made especially for greenhouse work ? 



Ves, we can ship promptly.

^ l:ict that the inininuim price was ad- 

 vanced quite radically. The lowest 

 l""i<e named this week, even on off-jjrade 

 'oal, was $1.25 for Pocahontas and New 

 Kivor, while the major companies had 

 '10 difficulty in getting $1.40. One rea- 

 '^on for this, of course, is the beginning 

 '>i buying on the part of real estate 

 ^gPnts, who must supply apartment 

 jjouses with their fall tonnage of coal. 

 ^''fre is an exceptional demand for 

 '^^iip and egg. Premiums of 10 an«l 

 V^ cents per ton have been offered 

 froclyj but the demand is now heavily 

 '" excess of supply." 

 -^^ to the amount of discussion on 



tlie war and its relation to the coal 

 trade, no better evidence is needed than 

 the large space devoted to this branch 

 of the subject in the ]>rin>'ipal coal 

 journals. The authority already quoted 

 summarizes tlie matter as follows: 

 •'Nothing has happened in years which 

 has concerned the coal trade so vitally 

 as the sudden cessation of coal ship- 

 ments from Europe to South America. 

 Few things have so influenced business 

 ])rospects as the great likelihood that 

 the United States will have to step in- 

 to that market and supply, for an indef- 

 inite period, its needs for coal. If the 

 war prove to be a sharp, decisive eon-
