GRAVITY SYSTEM. 



Can condensation be returned by grav- 

 ity under the following conditions? The 

 pressure is ten pounds. The farthest 

 end of the main return is 425 feet from 

 the boiler. From this point to within 

 175 feet of the boiler there is a fall of 

 seven to- eight feet; from the latter 

 point to within thirty-five feet of the 

 boiler but a few inches fall; in the last 

 thirty -five feet I could drop one to two 

 feet. If this is not practical, can you 

 suggest a plan to return by gravity, with 

 a maximum drop of nine to ten feet for 

 the whole 425 feet? T. F. B. 



If it were possible to reverse the con- 

 ditions existing in your plant, there 

 could be no question in regard to the 

 success of a gravity system. Even under 

 existing conditions I think the plan can 

 be made to work all right. If the boiler 

 can be lowered so as to get eighteen 

 inches fall in the last 175 feet, and still 

 keep the main return above the level of 

 the top of the shell of the boiler, through 

 all the house and until all the returns 

 have been collected into it, so there can 

 be no chance for back water in any of 

 the returns, it can then be dropped to or 

 below the level of the water in the 

 boiler with no ill effects upon the circu- 

 lation. Keep all the returns, except a 

 few feet of the main return near the 

 boiler, as far above the level of the 

 water in the boiler as possible, and still 

 maintain a uniform fall, as rapid as pos- 

 sible, in the pipes. L. C. C. 



VEGETABLE HOUSE. 



I have built one house 16x60 feet, 

 4-foot side walls, 9-foot ridge, which I 

 intend to use to raise lettuce and cucum- 

 bers. To heat this house 1 have an eight 

 horse-power boiler, horizontal fire-box 

 kind. I intend to run a 2-inch pipe 

 through the center of my house to the 

 far end, and return through three 1^4- 

 inch pipes on each wall. Will that be 

 enough to heat it? I shall regulate the 

 steam in accordance with the weather to 

 a certain extent. L. J. M. 



No, the six lV4-inch pipes you mention 

 will not be safe for severe weather in 

 Indiana. I do not think it would be 

 wise to attempt to run this house with 

 steam, the coils arranged on the outside 

 walls, with less than five pipes in each 

 coil, i. e., ten 1^4 -inch pipes for the

 Dear Sirs: Replying: to your letter of the 2nd inst., r«a:arding: your Eclipse Boiler I installed in my green- 

 houses two years ago, will say that the boiler is givi g me best of satisfaction. At the same time I 

 installed your boiler, I built an addition to niy greenhouses with about SOUO sq. ft. of glass, and the tirst 

 winter I saved fT.i.lO in fuel. This is a very large saving wh. n you consider that I hratrd 3000 sq. ft. 

 additional glass and at the same time saved 175 00 on fuel, and if I were to install another boiler, I certainly 

 would have no other than your Eclipse." Vours truly, LOUIS OTTO, Neenah, WU., Aug. 11, 1906.

hoiise in addition to the 2-inch riser un- 

 der the ridge. It would be a good idea 

 to place valves at each en^ of two of 

 the pipes in each coil, so as to cut down 

 the radiation for mild weather.

BOARD PARTITIONS. 



I have a short-span-to-the-south house 

 18x80 feet. I intend to build a new 



house 20x80 inside measure. It will 

 be connected to the old house. • I am 

 thinking of making my walls of cement 

 or grout, and will leave a 1-inch board 

 in the center of the outside wall to over- 

 come the radiation of heat. Would that 

 be practicable?
