 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 pressure 

 steam by adding steam drum. Best material) best workmanship. 

 Specially designed for greenhouse use; corrects the faults of other boilers.

can be very easily changed into an effi- 

 cient one by increasing the piping- in the 

 west house and running the risers, as 

 suggested, direct from the boiler to the 

 far end of the house, to return by the 

 manifolds already installed. L. C. C. 



CITY PRESSURE FOR HOT VATER 



I would like to know if I can keep my 

 greenhouse warmer by using city pres- 

 sure, thus raising the pressure to seventy- 

 five pounds. I have an open tank, ten feet 

 above the boiler, and force water with a 

 pump. State what diflference there would 

 be, if any, in using seventy-five pounds 

 of pressure instead of using, the open 

 tank. / C. B. 



While the increased pressure will make a 

 few degrees of difference in the tempera- 

 ture of the water, I doubt the advisability 

 of attempting to use city pressure when it 

 runs up to seventy-five pounds. If you can 

 use a reducing valve and bring it down to 

 fifteen or twenty pounds, it will be safer 

 and almost as efficient. Few hot water 

 boilers are safe under seventy-five pounds 

 of pressure. L .C. C. 



PAINTING STEAM PIPES. 



I am going to paint the steam pipes 

 in my houses, and some time ago I saw 

 something in the Review as to what 

 was best to paint with so that the 

 plants would not be injured. I have 

 gone through a number of the old issues 

 of the Review, but have been unable to 

 find the article. I will be much 

 obliged to you if you will inform me 

 on this subject. G. G. W. 



Unless it is absolutely necessary for 

 some reason, I would not advise paint- 

 ing the pipes in a greenhouse. Rusty 

 pipes are more efficient radiators than 

 painted or galvanized ones. If it is 

 necessary to paint them, give them a 

 coat of asphaltum varnish sometime 

 \vhen the houses are empty, and heat 

 them up so as to drive off all volatile 

 matter before the houses are filled with 

 tender plants. L. C. C.

E. HIPPARD, Youngstown, Ohio 



Galion, O. — E. A. Monroe, whose 

 houses were badly damaged in a recent 

 fire, has taken them down and quit busi- 

 ness. 



Pana, III. — R. O. Henderson fell re- 

 cently and cut his arm with a hatchet. 

 The wound is an ugly one and will dis- 

 able him for some time. 



KiRKWOOD, Mo. — Three houses for car- 

 nations have recently been erected here, 

 under the supervision of Arnold J. Schei- 

 degger, contractor. Two of the houses, 

 each 17x100 feet, were built for Henry 

 Niemeyer, and the other, 20x100 feet, for 

 E. P. Erker, of the Oakland Floral Co.
