Where There Is Condeosation 



— there is need for a Morehead Steam Trap. Condensation in 

 steam lines is akin to matter out of place — means wasted energy. 

 • If your lines are sluggish — if your houses are not of uniform 

 temperature, write us. We guarantee to drain your lines per- 

 fectly — return the pure, hot condensation to your boiler without 

 pu]!&p or injector or make no charge for the trial. Obey that 

 impulse — write now.

 be main- 

 tained in 

 your steam pipes, no matter 

 how the pressure at the boiler 

 fluctuates, if you equip your 

 main lines with these valves. 

 Carry 40 or 50 pounds pressure 

 on the boiler, set the

 line and you will always have a

TWO VEaETABLE HOUSES. 



I have a greenhouse 24x100 and thir- 

 ft en and one-half feet high to the ridge. 

 If contains twenty-two lines of 2-inch 

 pipe and one 4-inch feed pipe. Will 

 lliis piping furnish enough heat to grow 

 '•ucumbers, roses or tomatoes? There is 

 ii j,'enerator attached. I intend to build 

 "n additional house, 30x100. How 

 many lines of 2-inch pipe will be needed 

 to grow parsley or lettuce in this house? 

 ^yhe^e can I obtain reliable informa- 

 tion in regard to the growing of to- 

 "latoes and cucumbers? I am located 

 in northwestern Illinois. E. C. S. 



As to the present house, 24x100, a 

 Sood deal will depend upon the height 

 of the coils above the top of the boiler. 

 There is no reason why the house can

 is contained in any other 

 boiler. (Note the many 

 flues set close together.) 

 This is one reason why 

 the users of the 



"Superior Standard" Greenhouse Boflers 



find them perfectly satisfactory. We frequently receive re-ordera 

 from florists who have tested these boilers thoroughly and found 

 them even " Superior" to our claims.
