When a question regarding greenhouse 

 heating fails to state any of the particu- 

 lars as to height of walls, height of ridge, 

 amount of glass in sides, exposure, etc., 

 it is impossible to reply as exactly as 

 might be done if all the details were fur- 

 nished. 



FOUR PARALLEL HOUSES. 



I am contemplating building four 

 houses, each 25x200 feet. I will have a 

 12-foot driveway between the second and 

 third houses. I will build them seven 

 feet high at the eaves and use 16-foot 

 rafters, with three feet of siding and four 

 feet of glass on the sides, making a total 

 area of 28,000 square feet of glass and 

 2,700 square feet of siding. 



The houses will run east and west, and 

 I intend to place my boiler on the north 

 side of the houses, in the center of the 

 range, 100 feet from each end, and run 

 my main directly across the center of the 

 range. I had thought of using a riser of 

 suflScient size, probably 2-inch or 2^- 

 inch, directly under the ridge of each 

 house, and twenty 1^4 ■inch returns, the 

 risers to branch east and west in each 

 house. I would prefer, however, to use 

 ten or twelve 1^4 -inch risers and the 

 same number of 1^-inch returns, as I 

 have any amount of 1^4 -inch pipe and 

 have none of the larger size. I would 

 tise a 4-inch main and reduce one size as 

 I leave each house. I intend to raise the 

 main to a height of seven feet, just un- 

 der the eaves. The dome of my boiler 

 will be one or two feet below the level of 

 the greenhouse floors. Could I return the 

 condensation without the aid of a steam 

 trap or vacuum pumpf 



My location is middle Tennessee, and 

 at times the temperature reaches 10 de- 

 grees below zero, but very seldom; our 

 coldest weather, as a rule, is zero. I will 

 build a footway enclosing the main pipe 

 where it passes through the 12-foot 

 driveway. Where should I enter the 

 boiler with my return main and what 

 size of pipe should I use for it? I want 

 to maintain a temperature of 60 degrees. 



L. H. & S. 



With a plant arranged as you propose,

 riser to where the flow pipes are taken 

 off for the first house (the main flow 

 pipes in each house to be 2 1^ -inch), and 

 continued to the middle of the third

 middle of the last house with 2% -inch, 

 each house can be easily cared for on a 

 60-degree basis with seventeen li4-iDch 

 returns. The main return had better be 

 built up from 1%-inch in the most dis- 

 tant house to 3-inch from the last house 

 to the boiler. This should enter the 

 boiler by an opening on the underside of 

 the shed, near the rear end. L. C. C. 



A PLUMBER'S PLAN. 



A plumber writes to the Plumbers' 

 Trade Journal as follows: 



"I have a customer who desires to in- 

 stall a steam-heating apparatus in a 

 greenhouse 250 feet long by forty feet 

 wide, and having had no experience in 

 greenhouse heating, I would be pleased 

 to have your advice on the same, which 

 will no doubt be of interest to your many 

 readers also. The rafters each side of 

 ridge are twenty-four feet long and there 

 is two feet six inches of glass on each 

 vertical side, with two feet six inches of 

 double boarding and paper on each side 

 under the glass. My customer wants the

temperature 58 degrees when the mer- 

 cury outside is at zero. He wants to use 

 two steam boilers, which are to be placed 

 in a cellar eight feet below the green- 

 house floor, at the north end, and insists 

 that all pipes be under the benches. He 

 will not consider placing an overhead sys- 

 tem main in the greenhouse. He wants 

 a main flow to run across the ends of the 

 benches, with a loop of li4-iiich pipe un- 

 der each of six benches, one flow and one 

 return under each bench, and three 1%- 

 inch pipes on each side wall. Will there 

 be dry steam in the coils? The benches 

 are only two feet high from the bottom 

 of the bench to the floor and the house
