Greenhouse Heating. 



It is just a matter of prudence to 

 fill up any empty coal bins at once. 



A. N. PiERSON, Cromwell, Conn., Has 

 15,000 tons of soft coal stacked in the 

 open, covered with buckwheat coal to 

 prevent slacking. This is carried merely, 

 as insurance against strikes or railroad 

 blockades. Last season 8,000 tons of 

 coal were burned to heat 900,000 feet of 

 glass. 



SLUGGISH CIRCUIiATION. 



On page 94 of The Eeview of Novem- 

 ber 9 I noticed a query from H. E. H. 

 regarding poor circulation in his hot 

 water system. I would suggest that he 

 tap a fitting at the highest point on the 

 system and put in a pet cock to permit 

 the escape of air from the piping. I 

 had similar trouble in a house just built 

 and relieved the situation in the way 

 suggested. The inquirer will find the 

 generators advertised in The Review to 

 be quite helpful in sluggish systems.

A PARTITIONED GREENHOUSE. 



I am building a greenhouse, 10x20 

 feet, running east and west, with a 

 partition eight feet from the east end. 

 The temperature is to be 50 to 60 de- 

 grees in the larger room, 10x12 feet, 

 and 60 to 70 degrees in the smaller 

 section, 8x10 feet. The boiler shed is 

 at the west end of the house. The 

 other walls of the house are all ex- 

 posed. The height of the walls is five 

 feet; height to the ridge, seven feet 

 ten inches. The house will be used 

 for general stock, with space under the 

 benches for mushrooms. How can I 

 heat it correctly without pipes under 

 the benches, which would interfere with 

 the mushrooms? Will it be possible to 

 run a portion of the pipes under one 

 end of a bench for propagating pur- 

 poses? Kindly advise me as to the 

 proper number of pipes to be used and 

 how to run them. The heater will have 

 a capacity of either 250 or 300 feet of 

 radiation. My location is southeastern 

 Wisconsin. U. W. I. 



The following is perhaps the sim- 

 plest method of piping the house so as 

 to secure the conditions desired: A 

 2^ -inch flow pipe could be carried un- 

 der the ridge to the east end of the 

 house, where it could feed two coils of 

 four 2-inch pipes each. These could 

 start at the middle of the east end and 

 run along the end and sides of the 

 house to the boiler room. One coil 

 could be above the bench where mush- 

 rooms are to be grown, and the other 

 could be underneath, where bottom heat 

 is desired. The east room, 8x10, will 

 have about one-half more piping than 

 the other house, in proportion to its 

 size, and this will provide about 10 

 degrees higher temperature. Run all 

 pipes downhill and connect the expan- 

 sion tank at the highest point of the 

 system.
