 --both last year. You know how sat- 

 isfactory the Vertical Sectional is in 

 every way— well, the new member 

 of the family is this Round Sectional. 

 It is constructed on practically the 

 same economy principles as the 

 Vertical, and has more than made 

 good. Like to tell you all about it.

VATER UNDER PRESSURE. 



I am moving my greenhouses out 

 about three-quarters of a mile, where 1 

 can get better light and more room. Be- 

 sides moving my present glass, I will 

 build a rose house, 30x150 feet. I will 

 continue to use hot water. Would it be 

 advisable to use water under pressure? 

 I would like the opinion of anyone who 

 has tested hot water under pressure by 

 using a generator or other device for 

 confining the water. 



We have an excellent gravity water 

 system, with a reservoir up on the side 

 of a mountain. I can get 100 to 125 

 pounds of pressure from the city water 

 main. Could I use this pressure instead 

 of a generator, letting the water, as it 

 becomes heated in the pipes, press 

 against the water in the city supply or 

 water main? If there is a pressure of 

 100 pounds on water when it is cold, 

 how much greater will it be if it is at 

 the point where it is changed into steam? 

 I have a Richardson cast-iron sectional 

 bbiler. How much pressure will it 

 stand? Would it be advisable with a 

 cast-iron boiler to have a closed system? 



With a 4-inch overhead flow, how 

 many 2-inch returns should I have in a

I would not use a pressure or closed 

 system, but use an expansion tank, for 

 the following reason: Water circulates 

 at about 180 degrees with the atmos- 

 pheric pressure of fifteen pounds. Now, 

 if you raise the pressure by a generator 

 or by gravity, you bring your boiling 

 point up in like proportion. If you have

a water pressure of 100 pounds the boil- 

 ing point is pretty high, so that a slight 

 fall in pressure and a rise in tempera- 

 ture would cause the water to move out 

 through the supply pipe into the city 

 water system. Your boiler is liable to 

 make steam and create an enormous pres- 

 sure, which would break a cast-iron ' 

 boiler.
