pansion tank pipe to the high point of 

 the flow pipe or to one of the return 

 pipes? E. E. C— 111. 



About 600 square feet of hot water 

 radiation will be required for heating 

 each of the houses, and we would select 

 a boiler rated for 750 square feet of 

 radiation for heating the propagating 

 house, or 1,450 square feet for the two 

 houses. 



For flow pipes run a 214-inch flow 

 upon each plate, connecting the south 

 flow with four 2-inch returns under the 

 south bench and the north flow with 

 three returns under the north bench. 

 We would not vary the amount or ar- 

 rangement of the piping in the two 

 houses, except that the benches in the 

 propagating house should be partly 

 boarded in, in order to secure bottom 

 heat. One or more of the boards 

 should be hinged, for the purpose of 

 regulating the heat. There should be a 

 space of an inch or so between the 

 benches and the wall, to allow the warm 

 air to pass up and prevent the cooling 

 of the air over the benches. 



The slope of the flow pipes should be 

 away from the heater and it need not 

 be more than one inch in ten feet — and 

 one inch in twenty feet will answer — 

 for either flows or returns. The slope 

 of the pipes does not directly increase 

 the circulation; in fact, the less slope 

 the better so far as the circulation is 

 concerned, and it is only needed to allow 

 the air to escape from the pipes so that 

 they may be filled with water. The ex- 

 pansion tank may be connected with 

 any part of the system, but we prefer 

 to attach it to the highest part of the 

 system, when the downhill arrangement 

 is used, and thus avoid the expense and 

 bother of air valves. 



Not over ten feet between the houses 

 would be necessary in any case, and 

 since the north house is to be used for 

 propagating purposes, they may be built 

 together, with a common wall. The re- 

 turn pipes should be arranged in the 

 coils horizontally and should be one 

 foot below the bottom of the bench, 

 except, perhaps, in the propagating 

 house, where a somewhat smaller dis- 

 tance will answer. 



Cadillac, Mich. — J. P. Ilerzog has sold 

 his Cadillac Greenhouses to Percy Snell 

 and contemplates locating in some large 

 city. 



Valencia, Pa. — The early weeks of 

 1917 will see G. L. Curry & Sons operat- 

 ing their new greenhouses. These are 

 two connected houses, each 30x50, and 

 they also are rebuilding one sash house 

 16x36. When they have finished build- 

 ing they will have over 5,100 square 

 feet of ground covered with greenhouses, 

 as against 2,100 square feet last season, 

 or about two and one-half times their 

 former space. The material for the new 

 houses was furnished by John C. Mon- 

 inger Co., Chicago, the glass by Baur 

 Window Glass Co., Eaton, Ind., and the 

 pipe and heating system by the Kelly & 

 •Tones Co., Pittsburgh, Pa.
