KIND OF FUEL. 



S. G. Ni§^ey supplies the fuel for all 

 the largest greenhouses in the city of 

 Springiiekl, 0., and also in Urbana, and 

 says that in almost every instance he is 

 furnishing them a Smithers Creek, West 

 Virginia, gas mine run coal. In one case 

 he uses Fairmont, W, Va., coal. The 

 users report that this coal is strong and 

 suitable for the business, as they can 

 build their fires and leave them quite a 

 while, with the certainty of finding their 

 fires in good shape when they return. 



TO STOP SHORT CIRCUITING. 



We are building a new range, consist- 

 ing of six houses 22x100. They are to be 

 heated by steam. Can we attach the coils 

 to a large return pipe if we put a check 

 valve on each coil, or is it necessary to 

 run a separate return pipe for each coil 

 back to the boiler? The water level in 

 the boiler is two feet lower than the low- 

 est part of the returns. C. A. F. C. 



No check is needed on the system, but 

 put on a hand valve and water seal the 

 same; that is, a pocket in the return pipe 

 where water will collect and stop short 

 circuiting. G. T. E. 



A SMALL OHIO HOUSE. 



I have a small greenhouse which is 

 heated with hot water according to your 

 instructions, and the system worked to 

 perfection last season. The present 

 house is 12x60 and seven feet to the 

 ridge, with board sides three feet high. 

 It runs north and south and is connected 

 at the north end with a two-story build- 

 ing, 12x12, beneath which is the boiler- 

 room, built of concrete. I have a Wilks 

 boiler, with a 16-inch firebox. The flow 

 runs up to the ridge of the greenhouse, 

 then through the house, down through 

 two 2-inch pipes to the manifolds, and 

 back through six 1^4 -inch pipes on each 

 side, to the bottom of the boiler. We 

 used hard coal. This heated the green- 

 house to 65 degrees regularly, and also 

 furnished plenty of heat upstairs, in the 

 workroom. 



Now, as I know your instructions can 

 be relied on, I wish to ask your advice 

 with regard to a change which I propose

to make. I intend to build another house, 

 the same size as the present one and ad- 

 joining it on the east side, and I wish 

 to use natural gas for fuel. There is a 

 good pressure of gas here, and my boiler 

 is so arranged that I can tap it at top 

 and bottom with 2-inch pipe for hot 

 water. I do not care to carry over 40 

 to 45 degrees in the new house. The wall 

 between the two houses can be removed. 

 How shall I arrange the pipes in the sec- 

 ond house? A. O. N. 



In reply to your letter, would say that 

 you can pipe the second house the same 

 as the first one, with a separate flow and 

 return. G. T. E.

 them on the west side. The height to 

 the west gutter is five feet; the height 

 to each of the other two gutters is eight
