CONSERVE YOUR COAL 

 PRESERVE YOUR MONEY 



W 



E are staunch advocates of the nation wide movement for the conservation 

 of all natural resources, and have designed a boiler for greenhouses that 

 will produce the most heat at minimum amount of coal consumed. ^ The proper 

 placing of the tubes in the Gem City Boilers has been scientifically developed. 

 They are so arranged that the heated gases make two complete passes through 

 the water in the boiler shell, allowing absolute combustion of the gases, and 



permitting water to absorb the great- 

 est amount of heat before finally 

 passing into the stack. This is a 

 decided contrast to the usual waste- 

 ful method of having gases enter 

 the stack at a high temperature. 

 ^ By actual comparison, our boilers 

 contain more tube area per horse- 

 power than any competitor's. A 

 steel water leg entirely surrounds the 

 fire-box. In our boilers there are no 

 cast iron surfaces in contact with the 

 fire, consequently no liability of a 

 fractured section, a condition which 

 is especially disastrous when occurring in cold weather, causing at least a tem- 

 porary discontinuance of heat in the greenhouses, with the accompanying loss in 

 frozen plants. ^ Our boiler is substantially built in all details, and subjected to 

 a hydraulic test of 150 pounds before leaving our shops. ^ One of the prominent 

 florists of Baltimore, Md., Mr. James Hamilton, has given us his unsolicited state- 

 ment, that after installing one of our 50 horse-power boilers, he heated 40,000 square 

 feet of glass, at a 50% saving in his coal bill, as compared to the type we replaced.
