Is the only American Coal that has been officially Indorsed by the Governments of Great Britain, Germany 

 and Austria, and is the favorite fuel with the United States Navy, which has used it almost exclusively 

 for many years. Unequaled for the Generation of Steam and Domestio Fnrpoaes.

A PLANT HOUSE, 



I am building another house, 15x26, 

 for odd plants, and shall have three beds, 

 a 21^-foot one on each side and one in 

 the center. The house measures about 

 ten feet to the ridge and four and a half 

 feet to the gutters. How many feet of 

 2-inch pipes should I use, and where 

 should I put them? I am located in 

 New Hampshire. H. G. S. 



The best way to heat your house is by 

 eight lines of pipes working in pairs, 

 one flow and one return counting as two 

 pipes. Put these in the walks on the 

 sides of the beds. You will have a flow 

 and return on each side of each bed. 

 You will need about 225 feet of 2-inch 

 pipe. G. T. E. 



FOUR CONNECTED HOUSES. 



Will you kindly inform me how many 

 runs of 2-inch pipe will be required to 

 heat to 50 degrees, in zero weather, a 

 range of four connected, even-span 

 houses, each house being 14%xl50 feet 

 and six and one-half feet to the gutters? 

 I intend heating the houses with steam, 

 carrying about twenty pounds. I am 

 located in Michigan. C. D. L. 



Two-inch pipe for heating by steam 

 is, I think, too large, and creates too 

 much heat in one place; 1 14 -inch pipe 

 is the size preferred in most places where 

 a steam system is used. Six pipes in 

 each house will be a little more than 

 needed, but it is better to have a little 

 more, rather than a little less. Put these 

 under the edge of the benches. Put three 

 extra pipes on the outside walls and a 

 pipe under each gutter. Run a 4-inch 

 main across the end of the houses next to 

 the boiler house, and a return across the 

 farther end. Put the 2-inch return pipe 

 in tile pipe in the ground, sloping back 

 to the boiler six inches in the length of 

 the house. Keep the main pipe on a level 

 with the grade of the houses and the 

 return the same. Drop the boiler down 

 in a pit, so that the water line in the 

 boiler will be four feet below the point 

 where the return enters the boiler room. 

 Put on a tee where the return turns

down, and run a pipe out of the top so 

 as to make a siphon. Put on a valve 

 where you can reach it. This is a vent 

 pipe to let the air out of the system when 

 starting steam. This is a gravity system, 

 and will heat the houses on five pounds in 

 zero weather. G. T. E. 



THREE HOUSES AND A LEAN-TO. 



I have a greenhouse plant of the gen- 

 eral dimensions as described below, and 

 would like to know the proper way to 

 pipe it; also the size of boiler necessary 

 in order to get a temperature of at least 

 60 degrees in zero weather, in this Long 

 Island climate. There are three houses, 

 running east and west, and a lean-to 

 running north and south. House No. 1 

 is 14x75 feet, four feet six inches to the 

 gutter on the south side, five feet to the 

 gutter on the north side and nine feet 

 to the gable. Houses No. 2 and 3 are 

 even-span houses, 16x75 feet, ten feet to 

 the gable and five feet to the gutter. 

 There is no glass in the side walls. The 

 potting shed, 14x15, is on the east end 

 of house No. 1. The boiler pit, 12x13 

 and seven feet high, is under the potting 

 shed. The lean-to runs north from the 

 potting shed, and is 15x33 feet, ten feet 

 to the highest point and five feet to the 

 gutter plate. The houses each contain 

 two side benches and one center bench. 



J. T. L. 



I understand by your letter that the 

 system is to be hot water. In that case, 

 the following is the best way to heat 

 the range: The heating pipes are to be

2-inch wrought iron. House No. 1 shoukl 

 have ten pipes, with this arrangement: 

 Two under the bench next to house No. 

 2, four under the center bench and four 

 under the outside bench. There should 

 be a pitch up from the boiler to the far 

 end and back, calling two pipes a circula- 

 tion. In houses No. 2 and 3 run four 

 pipes under each bench. Connect the pipes 

 in pairs, so that you have two returns and 

 two flows under each bench. Eun a ;"> 

 inch flow pipe across the end next to tli'-' 

 boiler room, as high as convenient, an'l 

 run a 5-inch return pipe under the flov> 

 and about two feet below it. The lean 

 to should have four circulations, or eigl;' 

 pipes. G. T. E. 



FROM STEAM TO HOT VATER. 



I have three houses, 22x60, ten feet t> 

 the ridge and four feet to the eaves. Tli'- 

 houses are three-quarter span, and are 

 located in Indiana. I have steam heat, 

 and would like to change to hot water. I 

 have a sectional boiler, for' either steam 

 or water. 



There is a 5-inch pipe leading from 

 the boiler to the houses, a 4-inch pip^ 

 running crosswise through the three 

 houses, and a 3-inch flow running under
