 it will mean much to you. Why

greenhouse, and the results obtained 

 from following your advice have been 

 80 satisfactory that we arc again com- 

 ing to you for informaticyi. We have 

 just completed an addition to the house 

 built a year ago. The new house joins 

 the old one on the south at right an- 

 gles, so that the two together form an 

 L-shaped house, as you will see from 

 the enclosed diagram. The addition is 

 14x37 and eight and one-half feet high 

 to the ridge. The side walls are six 

 feet high to the eaves. Tlie lower half 

 of the side walls is double-hoarded, with 

 pa]>er between; the upper half is glass. 

 There is glass and a door in the south 

 end; at the north end there is a glass 

 partition and a door between the two 

 houses. 



Hot water lieat is used. The old 

 house contains a 2il.-inch ii^pin How, 

 running about two feet belpT^^ the ridge. 

 Would a continuation of this 2''j-inch 

 pipe to the south end of the new house 

 be large enough to feed coils under the 

 benches at the sides? How many pipes 

 would be needed in each coil? We 

 have on hand several hundred feet of 

 1%-inch pipe, which we shouhl like to 

 use if possible. The temperature de- 

 sired is 50 to 60 degrees in zero 

 weather. The location is southern 

 Michigan. The top of the boiler is a 

 little below the level of the ground 



WHY TAKE A CHANCE? 



You can't know (at best you only think you 

 know) what the temperature is in your green- 

 houses, nights and during your absences, unless 

 you have

 the size of the flow in the old house 

 unless it is necessary. W. F. C. 



The sketch indicates that a 2V{;-inch 

 overhead flow pipe and twelve \y\- 

 inch returns are suggested for heating 

 the new house. This would .answer 

 well, except for the fact that the new 

 piping would be connected with the 

 2Vj-inch flow pipe which supplies the 

 older house, llxLo. This makes about 

 500 square feet of radiation, which is
