THE SUPERIOR 



\ Improved Internal-Fired Steel Boiler 







Made in 10 sizes , to heat from 2000 to 6500 feet of 4-inch 

 pipe. No brick-work necessary; shipped on skids, all 

 ready to move into place and begin firing. Can be cleaned 

 without letting the fire out. All hubs made so they 

 can be used for either cast-iron or steam pipe. Tested 

 at 25 lbs. pressure and warranted; can be used for low 



Eressure steam by adding steam drum. Best material; 

 est workmanship. Specially designed for greenhouse 

 use; corrects the faults of other boilers. Lightest boiler 

 on the market capable of performing equal work. We 

 defy competition in prices on any boiler of equal 

 capacity. Investigate. Send for new illustrated cata- 

 logue, just out.

 It will bo an easy matter to fill the sys- 

 tem with rain water, which is ideal, and 

 from time to time replenish the expansion 

 tank from the same source, unless the 

 plant is very large, in which case it will 

 pay to build a cistern or tank to hold eave 

 water. , L. C C.

FILLING UNDER BOILER. 



How much, if any, filling of earth or 

 cinders should be put behind the bridge 

 or fire wall, back of the grates, under a 

 steam boiler of the usual round, tubular, 

 return-flue type? The mason who set my 

 boiler says it ought to be filled in to 

 about twelve inches of the under side of 

 the boiler. I am not sure he is right. 



W. H. 



It will make little difference whether 

 the pit is filled back of the bridge wall 

 or not. It has been my practice to exca- 

 vate only as deep as the top of the bridge 

 wall and then step down the height re- 

 quired for the fire box and ash pit. If 

 you wish you may fill back of the wall 

 even with its height, or you may allow 

 ashes and soot to accumulate there. If 

 it is left open it will be found an ad-

Heating of 

 Large Areas 



The Slmonds Improved Vacuum Steam 

 Heating Systems are especially adapted to 

 large heating plants or where long lines of 

 steam mains or heating pipes are necessary. 



These systems allow of securing equal heat 

 and a ponlilve circulation in the most distant 

 parts of the system, a'so all pipes, even re- 

 turn mains, can be carried high above ground 

 If desired. Every unit of heat In the steam 

 is utlUeed and every Inch of pipe surface Is 

 effectual heating surface.

 Steam Heating System yourself.

 as a man can enter the chamber to make 

 repairs, if necessary. L. C. C. 



It has been demonstrated that the 

 local plumber is not always the best 

 person to plan and install a greenhouse 

 heating plant.
