which a hole is drilled to admit a bolt 

 which when drawn up will clamp the 

 collars firmly about the tubes. Place a 

 collar about two inches from the end 

 of the sleeve on each of the two tubes, 

 bring the projecting ends of the collar 

 in line and, with a long-threaded bolt 

 passed between them, draw the joint firm- 

 ly together. If the joint is then well 

 packed it will give no further trouble.

BOILER AND FLUE. 



I would like to know how many 3-inch 

 or 3 M: -inch flues fourteen feet long, low 

 pressure steam, are required to heat four 

 greenhouses, connected, each 22x80 feet, 

 five feet to plate and twelve feet to 

 ridge. There is double glass in the west 

 gable and eighteen inches of glass in the 

 sides; also a house 6x88 feet, twelve 

 feet high at the end of the four houses, 

 six and one-half feet to plate; also a 

 work room above the furnace room, 

 20x30 feet. We must still have a surplus. 

 Two of the houses are to be kept at 

 65 degrees, two at 55 degrees and the 

 end house at 45 degrees with the tem- 

 perature at 30 degrees below zero outside 

 and a strong wind blowing. 



Will a furnace room twenty feet wide 

 accommodate another such steamer? 

 Could the furnace room be still narrower 

 and accommodate two such steamers? 

 How long should the furnace room be to 

 be handy in cleaning flues, etc.? 



We expect to run the feed pipe on the 

 ground up hill the length of the end 

 house; from this branch into each house 

 and again branch to each of four benches 

 in each house, connecting with 1^4 -inch 

 coil under benches and running down 

 hill, one foot drop to eighty feet, to 

 the west end of the houses, joining return 

 pipe back to the boiler. 



Do you know of others using this sys- 

 tem for steam with success? How large 

 should the feed pipe be at the boiler 

 (without dome), to heat eight houses? 

 How many 1 ^4-inch pipes are required to 

 heat each house? F. C. S. 



A thirty horse-power boiler will be 

 sufficient to heat the four greenhouses in 

 question. A 20-foot boiler room will 

 accommodate three such boilers, if care- 

 fully arranged side by side. A 16-foot 

 room would hold two boilers, provided 

 the retaining wall be made one of the 

 boiler walls. 



A 34-foot room is about as short as 

 a 14-foot boiler can well be worked in. 

 There should be four feet at the rear 

 of the boilers and the length of the tubes 

 in front, plus three or four feet for con-

venience in working and cleaning tools, 

 unless outside doors can be provided 

 through which flue-cleaning can be done. 

 Such an arrangement would require 

 about thirty-six feet in the clear. 



i do not know of those who are satis- 

 fied with the flow pipes on the ground, 

 unless it is a main riser carried through 

 an end house or potting shed and the 

 risers through the houses carried under 

 the ridge. A large plant built two years 

 ago with all steam pipes under the 

 benches is now being remodeled, the 

 risers being placed under the ridge. The 

 under-bench system produced a variation 

 of 20 degrees to 30 degrees in the two 

 ends of 150-foot houses. The overhead 

 flow through the house, with the distri- 

 bution at the end farthest from the main 

 riser has remedied the defect of the other 

 system above noted. Go slow on the 

 ground system. 



A 4-inch flow will carry the four 

 houses in question and a 4-inch opening 

 in each boiler connecting to a 6-inch 

 main flow will be sufficient for the eight 

 houses. Each of the houses to be run at 

 65 degrees should be provided with a 

 2 1,2 -inch riser and seventeen 1^4 -inch re- 

 turns, arranged under the benches and 

 each of the houses to be run at 55 de- 

 grees should have a 2-inch flow and four- 

 teen 1^4 -inch returns. The 6-inch flow 

 through the leanto cover house will pro- 

 vide enough heat except in severe 

 weather, when two 1^4 -inch returns on' 

 the outside wall should be available.

PIPING REQUIRED. 



We intend building a range of short- 

 span greenhouses this spring, Dietach's 

 construction, six in number, the north 

 house 20x100 feet, to be separated from 

 the others by a glass wall, to be used for

flowers, three benches. The other houses 

 are to be all in one; four houses to be 

 fourteen feet wide and the south house 

 seventeen feet wide with south wall five 

 feet high, two feet glass. The north 

 wall is to be six and one-half feet, the 

 same as the gutter supports, with glass 

 gable on one end. The flower house is 

 to be kept at 60 degrees and the others 

 at 50 degrees. The temperature is some- 

 times as low as 10 degrees below zero 

 outside. We would like to know the 

 amount of piping required when hot- 

 water is used and how the piping should 

 be arranged. Which is preferable: all 

 4-inch pipe, or smaller pipe? There will 

 be 110 benches except in the north house. 

 Would it be best to use small pipe for 

 returns in this house? If 4-inch pipe is 

 used would it be best to place all above 

 or below the benches in the north house? 



S. B. 



The house twenty feet wide to be 

 ruu at 60 degrees should be provided 

 with a 3-inch riser under the ridge and 

 eleven 2-inch returns arranged under the 

 benches. Each of the 14-foot houses can 

 be piped with a 2-inch flow under the 

 ri'lge and five 2-inch returns, or a 214- 

 inch flow under the second and fourth 

 valley gutters, supplying five 2-inch re- 

 turns in each 14-foot room. The 17-foot 

 house should have a 2 14 -inch flow and 

 eight 2-inch returns. I suggest this ar- 

 rangment because the cost of material 

 is somewhat less than for 4-inch cast-iron 

 pipe and the work of installation can be 

 much more quickly and cheaplv done.
