Greenhouse Heating 



Subscribers are invited to write the 

 editor of this department with regard to 

 any details of greenhouse heating that 

 are not understood. When information 

 is desired regarding the capacity of boil- 

 ers, or the amount of radiation required 

 for a greenhouse, the needed temperatures 

 should be stated in the inquiry, as well 

 as the amount of glass in tiie side walls, 

 and the dimensions and general arrange- 

 ment of the greenhouses. It is often help- 

 ful, also, to have a sketch showing the 

 location of the houses. 



CHANGINa BOILER. 



I am using a tubular boiler, 3x10 

 feet, which I have to crowd in order to 

 keep up the temperature in cold weather, 

 using steam. I have a boiler, 3^x10 

 feet, which I think would do the work 

 all right. At the present cost of soft 

 coal, would it be better to install the 

 3%xlO-foot boiler, or get a good cast- 

 iron sectional boiler? 



A. L. J.— N. Y. 



Whether it will be better to \ise the 

 3%xl0-foot boiler will depend largely 

 upon its condition, but if it is in good 

 shape, I should not hesitate to use it, 

 provided it is as large as will be needed. 



With a grate of ample size, so that 

 it will not be necessary to force the 

 fire, the tubular boiler will be quite 

 economical in its consumption of fuel. 



STOPFIKa TUBE LEAKS. 



What is the method of plugging 

 tubular boilers when a tube leaks? How 

 does a tube begin to leak? Does it give 

 way altogether, or does it just leak? 

 Can I check the leak before it becomes 

 necessary to shut the boiler off? 



J. D.— Pa. 



The replies to the Questions depend 

 largely upon the age and condition of 

 the boiler. If it is a comparatively new 

 boiler, with the tubes in good condition, 

 and leaks occur where the tubes join 

 the boiler heads, it is generally an easy 

 matter to stop the leaks, which are 

 usually due either to imperfect work- 

 manship when the boiler was con- 

 structed, or to the loosening of the 

 tubes where connected with the boiler 

 heads, caused by unbalanced expansion 

 and contraction. These leaks can gen- 

 erally be easily stopped. 



In older boilers the tubes themselves 

 may have rusted, or the tubes may have 

 been cracked in some way. If they are 

 badly rusted it may not be possible to 

 stop the leak, but if the tubes are in 

 fairly good condition it will be worth 

 while to paint the injured portion with 

 litharge and burn it on with a gasoline 

 torch. Repeated treatments of this 

 kind will stop a large leak.

The Market. 



The market is about the same as last 

 week, except for a few particularly 

 good chrysanthemums, asters and some 

 fine Sehwabcn gladioli. Asters on an 

 average last week were better than the 

 previous week, but they do not find a 

 ready market. The same holds true for 

 gladioli. It seems that everyone who 

 has a lot 10x12 feet is growing gladioli;
