A MATERIAL that has the power to re- 

 sist the transmission of heat and cold, 

 by holding in confinement a right pro- 

 portion of air, is secured for builders of homes 

 by the use of mineral wool. It protects against 

 frost, fire, sound, insects, rodents and germs, 

 and furnishes the comforts of seasonal warmth 

 and coolness and extreme dryness. Mineral 

 and organic fibers form its basis and it is made 

 into constructional consistency by converting 

 scoria and certain rocks while in a melted 

 condition to a fibrous state. Analysis of the 

 wool shows it to be a silicate of magnesia lime, 

 alumina, potash and soda, and consequently it 

 will not decay or become musty, nor yield 

 nourishment to insects and vermin. The ap- 

 plication of mineral wool is shown clearly in 

 the accompanying engraving. In working on

begins to fur below the bottom of each joint, 

 longitudinally, with a metal furring strip not 

 less than one inch wide; the strip, if corru- 

 gated, to be of No. 20 gage band iron, and if 

 not corrugated, No. 10. After fastening the 

 furring strips, lath the ceiling with metal lath. 

 The lath must be put on running crosswise 

 of the joists; and fill on top of the lath with 

 two inches of the wool. The furring strips 

 and lath should be fastened in place with 

 staples long enough to drive at least one inch 

 into the joists. Any kind of wire or metal 

 lath can be used with this ceiling. Lath with 

 an open mesh, such as the Roebling or ex- 

 panded metal lath, can be put on with the least 

 trouble, for the reason that the staples can be 

 driven more readily. Mineral wool is placed 

 upon the metal or wire lath, carefully packed 

 underneath the joist, and extended up between
