How to Keep the Greenhouse 

 Heating System Perfect this Winter 



W 



HEN you start the heating system this winter you may find 

 water dripping from sm{ill leaks or cracks in the boiler. 



Putting off the repair may mean serious trouble later with 

 heavy bills to face. 



The proper thing to do is to pour "X" Liquid into the boiler now. 

 This will repair the leaks and t>revent new ones. 



"X" is a marvelous Liquid. When poured in the boiler it in- 

 stantly combines with the water. In sizzling out through the leak 

 or crack the "X" is changed by the oxygen in the air from a liquid 

 into a solid, thus repairing the break. 



The heat in the boiler then hardens this repair, making it as 

 tough as metal, so that it will stand over 2000 pounds pressure. 



The surplus "X" being left in the system automatically stops all 

 new leaks which may develop due to expansion, or from other causes. 

 In this way "X" makes the boiler (and in a hot water system, the en- 

 tire system) LEAKPROOF. Keep "X" always in the water and you 

 will never have trouble from leaks, cracks, rust or scale. 



**X** Eliminates Rust and Scale. 

 Saves Coal 



"X" positively prevents all metal from pitting and rust. It elim- 

 inates scale in the boiler by chemically preventing the lime and other 

 scale-formini matter in the water from crusting on the boiler walls. 

 In this way WC" Liquid makes the boiler RUSTPROOF and SCALE 

 PROOF. 



Jet '*X** Liquid from your steamfitter — or we will 

 \hip direct, postage prepaid, on receipt of price 



Greenhouse owners who use "X" Liquid report a gratifying saving 

 in coal and greatly increased heating efficiency. 



"X" Liquid is the surest and most economical method of repair- 

 ing boilers. It is used by the United States Government, by thou- 

 sands of apartment house owners, and is recommended by over 

 28,000 plumbers who use it regularly. 



If you want to do the job yourself get a can of "X" Liquid. Other- 

 wise ask your plumber to do the job. His charges will be very rea- 

 sonable. 



The main thing is that "X" Liquid may save you thousands of 

 dollars in an emergency. li is ivise to keep "X" Liquid always on 

 hand. 



Unconditionally 

 Guaranteed 



"X" will make good on any 

 leaky or cracked boiler job— or 

 we will return your money. You 

 take no chances. "X" contains 

 no cement, powder or other in- 

 jurious substances. Beware of 

 imitations which cannot do what 

 the genuine "X" Liquid does.

sider it advisable to carry a 4-inch over- 

 head main in a small house. With the 

 returns well above the top of the boiler, 

 it would be possible to use the 4-inch 

 pipe as the flow, in which case about 

 thirteen 2-inch or six 2-inch and ten 

 1%-inch returns will be required. 



Our suggestion would be to put in 

 three 2% -inch flow pipes, with one three

WHAT would happen if your night 

 man fell asleep some night in 

 zero weather? What if you should 

 oversleep, or a cold wave hit your green- 

 house when your heat is at the min- 

 imum? It would mean ruin to your 

 plants — possibly ruin to you. There 

 have been many such cases. 



But not if you are equipped with the 

 STANDARD THERMOSTAT. The 

 Standard Thermostat protects you 

 from just such dangers. It will ring a 

 bell at your bedside when danger is near.
