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
