WATEK BOILS OVEB. 



In reading the article from W. S. in 

 The Review of October 6, 1910, in re- 

 gard to water boiling over, I feel 

 tempted to write you concerning the 

 cause and remedy. To my mind the 

 cause lies in the fact that there is an 

 air pocket at the highest point in the 

 heating pipes. This stops the circula- 

 tion, and the water in the boiler, in- 

 stead of circulating, expands into the 

 tank, and as the fire gets hotter it 

 creates a steam pressure. It is all forced 

 out, leaving the plates exposed, and 

 there is positive danger of serious in- 

 jury. 



The remedy lies in tapping this high 

 point and putting in an air-cock. This 

 should be opened occasionally. If on 

 opening water runs out, the pipes are 

 full and circulation will be positive. 



I had this trouble myself, which re- 

 sulted in a large crack in the crown 

 sheet of my boiler — a cast-iron one. 



I want to tell your readers how I 

 fixed this break, making it as good as 

 before. Letting the boiler cool, I 

 rubbed the fissure full of Smooth-On- 

 Joints, which is an iron cement, manu- 

 factured by the Smooth-On Mfg. Co., 

 Jersey City, N. J. In a couple of days 

 I fired up again and the boiler never 

 gave me any more trouble. J. L. J. 



PIPING FOB CUTTING BENCH. 



Will you please tell me whether the 

 hot water pipes under a cutting bench 

 would give good results if I put the bot- 

 tom of the bench under the pipes and 

 put the sand right on the pipes? I do 

 not get enough heat the other way. I 

 have ninety feet of 1-inch pipe in a 

 bench 3x10 feet. Is that enough? I

use a gas burner to heat it with, but 

 the sand does not seem to be warm 

 at all. G. H. P. 



If the heating pipes were passed 

 through the sand in the cutting bench, 

 more bottom heat would thus be pro- 

 vided than when the pipes are located 

 underneath. It would, of course, be nec- 

 essary to have the sand sufficiently deep 

 so that the pipes would not come within 

 four or five inches of the surface, and 

 greater care should be taken that the 

 sand does not dry out. Whether the 

 proposed change would give the results 

 desired cannot be told from the data 

 given, as nothing is said regarding the 

 area of exposed glass or the actual 

 amount of heating pipe in the house. A 

 good deal will also depend upon the 

 kind of plants to be propagated. As 

 a rule, it is not advisable to use pipe 

 as small as 1-inch for hot water heat- 

 ing, and it is possible that the trouble 

 is due to a poor circulation resulting 

 from the small size of the pipe. 



The heating plans for a propagating 

 house should be such as will provide 

 about 10 degrees of bottom heat, or, in 

 other words, the temperature of the 

 sand in the cutting bed should be 10 

 degrees warmer than that of the room 

 itself. To secure this, find out how

much piping will be required to main- 

 tain the desired temperature in the 

 house, and then put in from twenty-five 

 to thirty-five per cent additional piping 

 under the cutting beds, to provide the 

 necessary bottom heat. If the arrange- 

 ment is such as to give a good circula- 

 tion the ninety feet of 1-inch pipe 

 should give a temperature of 60 de- 

 grees, with an additional 10 degrees of 

 bottom heat, in a house which has about 

 sixty-five square feet of glass. • ■ 



CBUDE OIL FOB FUEL. 



We should like to know whether 

 crude oil can be used satisfactorily in 

 a steam boiler to keep a steam pressure 

 of about thirty pounds. We can get 

 crude oil for $2 to $2.50 per barrel and 

 coal for $2.50 to $3.50 per ton. Would 

 there be enough odor to harm the plants
