X" BOILER LIQUID IS THE WATCHMAN FOR THE 

 WHOLE GREENHOUSE HEATING EQUIPMENT 



Every greenhouse keeper knows the 

 possible cost<il a single leak in his 

 heating system. 



He cannot be inspecting every minute. 

 Leaks occur and the keenest eye can- 

 not foresee them. 



"X" Boiler Liquid works from the in- 

 side. The instant a leak occurs it is 

 there to repair it. Makes a metal-like 

 repair in half an hour. Stands 500 

 lbs. pressure. 



Also prevents rust and scale— those 

 heat-consuming twins present in every 

 system using hard water. 



One-eighth inch of scale in a boiler 

 needs 25% more coal for the same 

 heat. 



Use "X" BOILER LIQUID for INSUR- 

 ANCE. 



Use "X" BOILER LIQUID for ECON- 

 OMY. 



Get *'X" Liquid from your steamfitter — 



Or we will ship direct, postagre prepaid, on receipt of price.

Travis Rocker Grates 



Use better grates. The Travis 

 Rocker Grates are quickly in- 

 stalled and rest on the original 

 grate supports, the same as 

 your straight bar grates.

In visiting the greenhouses of other 

 florists, have you ever noticed how often 

 the chain running from the damper 

 regulator to the draft door is discon- 

 nected? This is usually evidence that 

 the regulator has failed to operate 



properly. The damper regulator, al- 

 though a small part of the boiler, is of 

 great importance if you wish to avoid 

 frequent firing or constant attention for 

 regulation. Along with other heating
