CONSERVE YOUR COAL 

 PRESERVE YOUR MONEY 



E are stanch advocates of the nation-wide movement for the conserva- 

 tion 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 com- 

 bustion of the gases, and permitting water to absorb the greatest amount of 



heat before finally passing into the 

 stack. This is a decided contract 

 to the usual wasteful method of 

 having gases enter the stack at a 

 high temperature. 4 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. temporary discontinuance of heat in the greenhouses, with the 

 accompanying loss in frozen plants, fl Our boiler is substantially built in all 

 details, and subjected to a hydraulic test of 150 pounds before leaving our 

 shops, fl One of the prominent florists of Baltimore, Md., Mr. James Hamilton, 

 has given us his unsolicited statement that, after installing one of our 50 

 horee-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.
