temperature of 60 degrees. On the mar- 

 gin of the sketch you have a calculation 

 which shows the number of square feet 

 of glass to be 9,000. It is impossible to 

 see how a greenhouse 63x150 feet, with 

 glass in one side wall and presumably in 

 one or both of the end walls, could have 

 less than 12,000 square feet of glass. 



A 40-horsepower boiler will be neces- 

 sary for 9,000 square feet of glass and 

 a 50-horsepower boiler for 12,000 

 square feet of glass. The grate sliould 

 have an area of fourteen square feet for 

 the small size of boiler and sixteen 

 square feet for a 50-horsepower boiler. 



If the house has only 9,000 square 

 feet of glass, it would be advisable to 

 use three 2%-inch flow and fifteen IVj- 

 inch return pipes. If there are 12,000 

 square feet of glass, twenty returns will 

 be needed. The main flow pipe should 

 be 4-ineh and the main return a 2-inch 



pipe. 



PIPE FOR TWO HOUSES. 



1 wish to install a hot water heating 

 system with radiating capacity large 

 enough to meet the needs of two green- 

 houses, one of which has these dimen- 

 sions: 11x93 feet; height at ridge, eight 

 feet six inches; lieight at cave plate, 

 five feet nine inches; wall of concrete 

 three feet high in both ends; remainder 

 glass. The otlier 's dimensions are: 17^: 

 xllO feet; height at ridge, eleven feet 

 six inches; height at eave plate, six 

 feet six inches; north wall and ends of 

 house of concrete three feet high; re- 

 mainder glass. The boiler is to be set 

 in a pit three feet from the greenhouse 

 waU. 



Will you kindly advise as to size of 

 i)oiler and give a list of the pipe which 

 will be required for the system t 



W. E. H.— W. Va. 



The house 11x93 feet will need two 

 214-inch flow pipes, one on each of the 

 side wall j)lates, and four 2-inch returns, 

 placing two returns under each of the 

 side benches and connecting th(>ni with 

 the corresponding flow pipes. 



In the wider house, which has three 

 feet of glass in one wall as well as in 

 seventeen feet of the other side wall, 

 and one end, three 2iA-ineh flow pipes 

 and nine 2-inch returns will be required, c' 

 Place one flow pipe on each of the side 

 wall plates and the other three feet be- 

 low the ridge. There should be a coil of 



Why 



think that ordinary laid-up brick is the proper 

 furnace lining when you may easily know 

 that no material equals 



FURNACE LINING 



when molded into baffles, side walls, bridge walls, 

 and front and back arches? 



Give PLIBRICO a trial in one boiler. Learn what it means 

 to be free from falling brick and crumbling mortar, to be always 

 ready to carry peak loads. It lowers maintenance cost while 

 increasing production. 



Then install PLIBRICO in all your boilers.

 for about 1,800 square feet if natural 

 gas is to b(> usofl. or 2,400 square feet
