Will you kindly give me some advice 

 on the heating of my greenhouse, which 

 is 20x50 feetf The side walls are six 

 feet high; the lower half of the walls 

 consists of concrete blocks; the upper 

 half is glass. The house is twelve feet 

 two inches high to the ridge. It runs 

 east and west. The boiler is at the 

 west end of the greenhouse, at the back' 

 of the residence. It is a steel tubular 

 boiler, thirty-eight inches in diameter 

 and six feet high, and contains eighty- 

 five 2-inch flues. The top of the boiler 

 is on a level with the greenhouse floor.

 cut in the side of the boiler, so as to 

 heat with hot water. The 4-inch flow 

 and return pipes run along the west end 

 of the greenhouse. From the 4-inch 

 main a 2-inch pipe runs under each side 

 of the middle bench, and each is con- 

 nected with three 2-inch returns. There 

 is also one 2-inch pipe under each gut- 

 ter, each connected with three 1%-inch 

 returns. 



The 4-inch flow and return pipes have 

 packed joints; these joints leak and I 



The Value of a Thermostat 



LET A FLORIST TELL IT 



IJERE is what a greenhouse man said in a letter to The Review: "The 

 ^ * value of a thermostat in a greenhouse may possibly interest you, so I take 

 the present opportunity of explaining its advantages. Three weeks ago I in- 

 stalled a Standard thermostat, made by the Standard Thermometer Co., putting 

 it in my rose house, 200 feet from the residence. After sundown each day I set 

 the low contact hand at 67 degrees and the high contact hand at 65 degrees. 

 The black temperature hand, to record 60 degrees, plays between these figures. 

 Should the temperature rise or fall, the alarm bell, just over my bed, rings 

 loudly. I consider this Instrument a boon to any florist with a me- 

 dium-sized range, for it dispenses with the services of a night fireman. With 

 correct firing, I can keep a steady temperature of 60 degrees at night in the 

 rose house and also in four other houses, in all about 6000 feet of glass."— Thomas

\ O. B.— Ohio, 



To heat a greenhouse 20x50, with 

 three feet of glass in each wall, I would 

 use three 2M!-inch flow pipes, placing 

 one upon each plate and the other about 

 two or three feet below the ridge. To 

 each of these flows connect a coil of 

 four 2-inch returns. One coil may bo 

 on each side wall or under the side
