Nolfnisfht fireman required — as the magazine or coal chamber holds 

 sufficient fuel to keep fire 10 to 12 hours without attention. Best made for a 

 small greenhouse.

Dear Sirs: Keceived your boiler 0. K. As for the boiler, it is all you 

 claim for it and more. Would not trade it for six like the cast iron one I 

 had before it. When it comes to keeping heat over night, it's right on the 

 job. During our coldest vireather here this winter (7 below) it kept the 

 house at 55 degrees, and did it easy on slack and nut mixed. 



Thanking you again for past favors, I remain, 



/-- Yours truly, 



(Signed) JAMES McCRAY.

 the boiler. The expansion tank is four 

 feet above the boiler. ¥. M. D. — Can. 



The sketch shows the house to be 9x20 

 feet, with four 1%-ineh returns under 

 one side bench and six 1-inch returns 

 under the other bench. The coils are 

 supplied by a 2-inch flow pipe running 

 around one end and one side of the house 

 just above the bench. 



The radiation is about right in amount 

 for the conditions mentioned above, but 

 unless the pipe specified is on hand, a 

 number of changes would be advisable. 

 One would be to use 2i/4-inch pipe for the 

 main flow and return pipes, even though 

 the outlet and inlet to the boiler are 

 only 2-inch, using reducers close to the 

 boiler for making the connections. Then 

 it would be well to carry the flow pipe 

 on one of the wall plates, instead of on 

 the wall just above the bench. On some

It would be advisable to use 1%-inch 

 pipes for the north coil instead of six 1- 

 inch pipes. This would reduce the fric-

reason for increasing the size of the flow 

 and return pipes is the fact that the 

 flow pipe is but slightly above the re- 

 turns. With a 2-inch flow pipe and ten 

 returns, an uneven circulation might re-
