WILKS SELF-FEEDING 

 HOT WATER BOILER 



For Economy, Durability, Dependability 



InstaU a WILKS 

 and forget your 

 troubles. 



No night fire- 

 man required— 

 as the magazine 

 or coal chamber 

 holds sufficient 

 fuel to keep fire 

 10 to 12 hours 

 without atten- 

 tion. Best made 

 for a small 

 greenhouse.

and 120 square feet for the office, which 

 is also 16x16 feet. 



If it is possible to place the boiler low 

 enough to give a fall of six inches to 

 the return from the residence and still 

 have the lower end one foot above the 

 top of the boiler, it will be all right to 

 run the pipes as suggested. The re- 

 turn should pass underground between 

 the greenhouse and the residence, one 

 foot below the surface. The size of the 

 flow and return pipes to the office and 

 residence as they pass through the 

 greenhouse should be four inches, but 

 from the office to the residence they may 

 be reduced to S^^-inch pipes and at the 

 west end of the residence may be 2-inch. 

 Run both flow and return pipes with a

Condensation — a Parasite 



Just as certain fungi sap the strength and vitality 

 of the plants on which they feed — Condensation 

 robs the power plant of energy. 



Condensation can't be prevented — butjit can be 

 eliminated as rapidly as it occurs — before it can 

 steal the energy of your steam. 



There is no more efficient steam trap than the 

 Fisher — it is practically trouble proof and is 

 adaptable to either high or low 

 pressure by simply changing 

 the valve seat. 



May we send you our 

 trap book explaining 

 the simplicity and effi- 

 ciency of the Fisher?

To keep your water 

 system entirely free 

 of air — use the 

 Fisher Air Trap, 

 Type 30. It never 

 fails.
