Tests,Prove Str,ength of New Wail Material

An interesting demonstration was conducted under, the guidance of unbiased engineers recently, on the standard 9"9. il.h sheathing of lumber ordinarily specified for,wall bulldrng purposes, and Bishopric Base,_a patented wall material which has been sold for 18 years in-the East and is now manufactured in Los Angeles Ly the Bishopric Mfg. Co. of California.

"We have made this test in practically every city in the country and _succeeded in having building oidinances altered -everywhere so as to permit- using Bfshopric Base in lieu of wood sheathing" says J. W. Fo"rd, Jr., president of the Bishopric organization, who personally supervised the local tests.

"'We used a_ test panel with one inch sheathing of lumber on one side and standard lathing on the oth-er which was subjected to a pressure of 2,24[lbs. This test panel then showed a 6 in. movement of the frame which would be_ enough to crack and practically ruin any wall. On the other hand, we made up a test panel with-Bishopric Base on both sides and then applied etual pressure. The uooe, sill moved only.41 in. al-a load-oi 2,+00 tbs. A totil'of 4,400 lbs. were applied before the Bishopric Base panel moved over I rn.

"This startling demonstration has convinced builders everywhere that it is needless to waste money and labor to build walls with sheathing and buildins paper. Bv using Bishopric Base they reduie their labor-and^ materiil costi and they have the advantage of the interlocking mechanical key which holds cement or plaster in an everlasting grip.

A B.ishopric built wall is practically fire proof and it will not buckle or sag; it is sound deadening and moisture proof and has innumerable advantages oveiother types of-wall building material.

"Bishopric Base is just being introduced into the Los Angeles territory-and has been enthusiastically adopted by the leading building material dealers. It his swipt thi Eastern states and- is almost universallv used fbr its economy and strength. We find that builders of the Southland are anxious to,use this better way to build stronger walls at lower cost.'

CATS THAT DIDN'T COME BACK

Beq,utiful birch

Doors

America's most versatile hardwood, and one of the hardest of the hardwoods. Birch doors can be used with practically any kind of trim, as it lends itself perfectly to the production of any efiect, particularly adipted tL gray and brown acid staining, red or brown stained mahogany, walnut stain or natural finish.

We manufacture veneered doors in all the hardwoods, such as gum, oak, mahogany and walnut, in a wide variety of styles adapted to homes, apartments, schools hotels, hospitals, and office buildings.
