horse-power of boiler will handle these 

 houses safely in this locality, the south- 

 western part of New York state? One 

 end of the greenhouses is protected 

 across their entire width by the boiler 

 house. The temperature outside often 

 drops to 15 degrees below zero. The 

 piping will be brought up to require- 

 ments. L. F. 



Three of the houses shown in the 

 sketch are each 110 feet long. No. 1 is 

 twenty-one feet wide, with thirty inches 

 of glass in the outer wall. No. 2 is six- 

 teen feet wide and is located between 

 houses 1 and 3. The latter is twenty- 

 one feet wide, with the exposed wall 

 double-boarded and papered. House 

 No. 4 is built across one end of Nos. 

 1, 2 and 3 and is twelve feet wide, with 

 walls eight feet high, of which five feet 

 are glass. The boiler is located at the 

 other end of the main houses. 



While a twenty-five horse-power 

 boiler would heat these houses, one of 

 thirty-five horse-power would be more 

 economical in severe weather, and if 

 the range is to be enlarged it might be 

 well to put in a fifty horse-power boiler, 

 which would answer for twice the pres- 

 ent glass area. 



The temperature desired is not 

 stated, but for 60 degrees I would run 

 a 2^-inch main overhead through house 

 No. 1, and extend it as a I'^-inch main 

 to connect directly with the coils in 

 house No. 4. For house No. 1 nine 1^- 

 inch returns would be required, or seven 

 returns for 50 degrees. In house No. 2 

 use one 2-inch overhead flow pipe and 

 six returns for 60 degrees or five re- 

 turns for 50 degrees. House No. 3 

 should have a 2-inch overhead flow and

nine 1^/1 -inch returns for 60 degrees, 

 although eight might answer if the 

 house is in a sheltered location. Seven 

 returns would suffice for 50 degrees. In 

 house No. 4, connect the flow pipe 

 brought in from house No. 1 directly 

 with the returns, of which there should 

 be eight for 60 degrees or six for 50 

 degrees. A 1 14 -inch pipe for the drip 

 should be carried through house No. 3. 

 If the boiler is at the end of house 

 No. 3, the main in that house should be 

 2i/.-inch and a IViJ-inch pipe should be
