Use it for patching when you cannot afford to cut a boiler out. 

 ELASTIC FIRE BRICK can be used for all fire b^ick purposes.

To correct this defect, I should run an- 

 other 2% -inch overhead flow pipe, using 

 one for each coil. 



It is stated that the boiler is three 

 feet down in a pit. If this means that 

 the floor of the pit is three feet below 

 the floor of the greenhouse, it would ap- 

 pear that some of the returns are below 

 the top of the boiler. If it is not possi- 

 ble to lower the boiler, I should raise 

 the returns so that they will all be 

 above the top of the boiler. 



Of course the main returns should be 

 of the same size as the main flows, and 

 instead of a 2-inch return from each 

 coil, uniting with the return from the 

 other coU in the same house and running 

 to the boiler as a 2%-inch main return, 

 I should run a 2i^-inch return from each 

 coil and either carry this back to the 

 boiler or unite the two returns from 

 each house and run to the boiler with a 

 3-inch return. 



The use of a "booster" on the system 

 should help the circulation, but the re- 

 sults will not be marked, both on ac- 

 count of the number of returns to be 

 supplied and because some of them are 

 below the top of the boiler. As with an 

 opon-tank system, when tne combined 

 area of the returns is so much more thin 

 that of the flow pipes, the circulation ii 

 confined to the upper pipes in the coils. 



OALKINQ HOT WATER PIPES. 



Please tell us the best calking 

 method for 4-inch hot water pipei. 

 Should sal ammoniac and iron filings 

 be used, and in what proportion, or red 

 lead and oakum t Is there any advan- 

 tage in using litharge or japan t 



T. M. C— Wis. 



The use of sal ammoniac for the 

 calking of 4-inch pipes is not advis- 

 able, smce, although it is excellent for 

 making a tight rust joint, it is likely to 

 crack the pipe. 



It is better to use oakum and either 

 iron turnings or an iron cement for the 

 purpose. A ring of oakum should first 

 be used. After being well twisted, it 

 should be firmly driven into place. Ths 

 iron turnings should be used to fill all 

 of the remaining space, the layers as 

 driven in filling one-half to three- 

 fourths of an inch. 



When iron cement is used, it should 

 be driven in between alternate rings of 

 oakum. 



There is also danger of cracking ths 

 pipes with red lead, or litharge, but a 

 small amount may be used with ths 

 oakum before the iron turnings ars 

 added. It is not needed when iron es- 

 ment is ussd.
