stead of one. Or, I might take out 

 the 6-pipe header at the north end and 

 divide the coil in halves lengthwise. 

 Or, as there are two taps in the top 

 of the boiler, I might take one flow 

 from each tap, using one for the car- 

 nation section and the other for the 

 general plant section; now they all 

 draw from one flow. I use a mercury 

 generator. C. H. L. — Mass. 



Since nothing is said regarding the 

 size of the boiler, I cannot determine 

 whether or not it has sufficient capacity 

 to heat the present house. It is possi- 

 ble, of course, to increase the capacity 

 of a boiler by the addition of one or 

 more sections, but the capacity is not 

 increased in proportion to the addition 

 made to the fire surface. 



So far as can be judged from the 

 description and sketch furnished, the 

 principal trouble is in the size of the 

 return pipes from the coils in the car- 

 nation houses, since the l^^-inch re- 

 turns must handle the water from coils 

 eighty-three feet long, each containing 

 six 2-inch pipes, besides that in the 

 flow pipe, or a total of about 300 square 

 feet. 



The plans suggested for correcting 

 the difficulty are excellent, provided 

 the returns are made of the same size 

 as the flow pipes. I would advise the 

 use of two 2-inch flows to supply the 

 coils in the part of the house used for 

 general greenhouse stock, and would 

 then run two 2% -inch flows to supply 

 the coils in the carnation section, with 

 returns from the coils of the same size 

 as the flows. There should be gate or 

 angle valves on the 2-inch flows, mak- 

 ing it possible, if necessary, to force 

 more of the water to the coils in the 

 carnation house. This would be better 

 than to run additional 2-inch pipes, as 

 suggested, although the latter would 

 give good results, if returns of the 

 same size were used.
