The Weekly Florists' Review. 



Mabch 14, 1912. 



little over 20,000 feet of glass, exposed 

 to the full sweep of the wind. The 

 temperatures inside ranged from 50 to 

 60 degrees, as wanted in the various 

 houses. 



To figure the comparative cost of oil 

 and coal, each grower will have to con- 

 sider his cost of coal, cost of oil, 

 whether his coal ashes are a nuisance 

 or a useful commodity, the saving in 

 labor cost, and other things which will 

 be peculiar to his own situation. In 

 some cases the increased capacity of the 

 heating plant may make it possible to 

 hook on that extra house without hav- 

 ing to increase the now fully loaded 

 boiler capacity. We believed the easiest 

 way to figure it out was to go ahead 

 and try it, which we are doing. We 

 have previously burned natural gas and 

 coal, and so far in this test the oil has 

 proved the most satisfactory fuel of 

 the three. W. H. Gulp. 



TWO CUCUMBES HOUSES. 



I am building two greenhouses, each 

 12x100 and eight feet to the ridge, for 

 forcing cucumbers. I am located near 

 Seattle, Wash., and want a night tem- 

 perature of 60 to 62 degrees. I ex- 

 pect to put in a hot water system. 

 Please give me information as to the 

 placing of the boiler so as to secure 

 the best results. Also state the right 

 size of the flow and return pipes, I 

 have a ten horse-power boiler, with 

 eighteen return flues. W. A. S. 



Whenever possible, the boiler should 

 be so placed that it will be entirely 

 below the level of the greenhouse floor, 

 and if it can be several feet lower it 

 will be all the better. The best way 

 of heating the houses will be to run 

 2%-inch pipes upon each of the plates 

 as flows, and connect each flow pipe 

 at the farther end of the house with 

 two 2-inch returns. This, of course, 

 will give two 2^-inch flows and four 

 2-inch returns to each of the houses. 

 Run a 3-inch main flow, and a return 

 of the same size, from the boiler to 

 each of the houses. Have the flows 

 run downhill and connect the highest 

 point in each flow pipe with the expan- 

 sion tank. 



A NARROW HOUSE FOR ROSES. 



We have a range of three houses, one 

 20x76i/o, one 21 x 87y2 and one 11 x 

 87%. We are going to build another 

 house this spring, 27^^ x 76%. We 

 should like to know whether the small 

 house could be used for roses, or is it 

 too narrow and low? It is five and 

 one-half feet high at the sides and 

 eight and one-half feet to the ridge. 

 We are thinking of putting a partition 

 on both sides of this house, as all the 

 houses are connected and the small 

 house has a row of stationary sashes 

 up to it, with a solid bench below. This 

 house contains one 5-foot bench and 

 one 3-foot bench; both are raised 

 wooden benches, about eighteen inches 

 high. The houses all run northeast to 

 southwest. Would one 2% -inch flow 

 and six 2-inch returns, three under each 

 bench, heat the narrow house suflS- 

 ciently for roses, and would it be all 

 right for roses, with these changes? 

 This house is the southeast house, or 

 south house, as some would call it. We 

 use hot water heat. Our location is 

 western Indiana. W. S. K.

Narrow houses like the one described 



could be used for roses, but they would 

 be better for carnations and especially 

 for violets. If to be used for roses, 



there would be no diflficulty in heating 

 it in the manner proposed. ' To pipe 

 it for carnations, use only four returns.
