IT PAYS TO USE— 



HiSnC HRE BRICK '■!^"JS"JL'"il'LS°i''- 



Use it for patching when you cannot afford to cut a boiler out. 

 ELASTIC FIRE BRICK can be used for all fire brick purposes. 



Hoerber Bros., Geo. Wittbold Co., Miller Bros.» C. Hausermann, John Reading and BroadbecM the Florist 

 are using Elastic Lining. These are only a few of the thousands we are selling.

each radiator and another should con- 

 nect each radiator with the main re- 

 turn pipe. 



A 4-inch main will also be required 

 for the greenhouse. This may run 

 through the house on the east row of 

 purlin posts, the flow pipe to the resi- 

 dence being carried on the west row of 

 posts; or, after being carried into the 

 greenhouse near the center, it may be 

 used to feed three 2%-inch flows, one of 

 which may be on each side wall plate 

 and the third on the east row of the 

 purlin posts. Taking into account the 

 radiation furnished by the flow pipe to 

 the residence, it will be possible to 

 maintain a temperature of 60 degrees, 

 when it is zero outside, by using thir- 

 teen 2-inch returns. Four of these may 

 be on each of the side walls and the 

 others in the walks on the sides of the 

 beds. The return pipe from the resi- 

 dence may be either in the west walk 

 or under one of the beds. All pipes, 

 both flows and returns, should fall about 

 one inch in fifteen feet and the highest 

 part of each flow pipe should be con- 

 nected with the expansion tank. 



A 25-horsepower steam boiler should 

 heat the residence and two greenhouses 

 28x64 feet to 60 degrees. There should 

 be eight square feet of grate area in 

 the boiler. 



OIL, COAL Ain> OIL BUBKEBS. 



Please tell me approximately the 

 number of gallons of crude or fuel oil it 

 will take to give the same amount of 

 heat as a ton of good bituminous steam 

 coal, also the name of a firm that manu- 

 factures oil burners. C. F. B. — Wash. 



The comparative efficiency of fuel oil 

 and soft coal depends not only upon the 

 number of thermal units which they 

 contain, but also upon the economy of 

 the oil burners and of the boilers in 

 which the coal is burned, together with 

 the skill of the firemen. 



Tests of oil and soft coal show a wide 

 variation in the amount of water they 

 will evaporate. On an average, the heat- 

 ing value of a ton of bituminous steam 

 coal which testa 10,000 B. T. U. is equal 

 to 100 to 120 gallons of fuel oil. As a 

 rule, the efficiency obtained from fuel 

 oil is much greater than that from coal. 



Among the manufacturers of oil burn- 

 ers are the S. T. Johnson Oil Burner Co., 

 1337 Mission street, San Francisco, Gal.; 

 Staples & Pfeifer, 102 Stewart street, 

 San Francisco, and the Fess System Oil 

 Burner Co., 220 Natoma street, San 

 Francisco.

The actuating element of the Standard Record- 

 ing Thermometer is of lamina metal, which, be- 

 sides being extremely sensitive to temperature 

 changes, is practically indestructible. Record 

 charts are furnished e.ither daily or weekly, and 

 the whole mechanism is" contained in an attractive 

 metal case fitted with lock and key, which insures 

 the record from being tampered with. 



The clock movement is of extremely high grade; 

 eveiy thing about the instrument is up to the high- 

 est possible standard of manufacture.
