Where is all the needed lumber so lavishly used in building to come from? The average normal supply would not be sufficient and the supply cannot be increased for a period of years simply because Russia, which normally supplies 50 per cent of the lumber for the European markets, has fallen into such industrial chaos, and needs so much material for her own reconstruction that, according to one authority, she will not be able to export lumber again before 1922 or 1923. In consequence, the burden of supplying lumber to the world market at the present time will fall upon America. The effect upon prices, as well as upon quality of product, will be inevitable. The excessive demand will not only compel injurious denudation of our forest lands, but will more and more force the cutting of inferior timber.
How to Save Lumber
In view of such conditions there is urgent need of conserving our lumber supply by every available means, the simplest and most direct of which is to confine lumber strictly to its legitimate uses or, at any rate, not use it where more fitting materials are at hand. Take the abnormal demand pressure off lumber in every possible way, and we reduce the danger of a lumber famine that threatens us for some years to come. Thus, lumber should not be used in the exterior walls of a house, where it is exposed to the vicissitudes of the weather or to the trial of fire, especially when building material such as brick, which is nearly as cheap, and considering its durability and fire-safety, far more economical, is everywhere in evidence.
Lumber has its very legitimate and varied uses, but among them is not outside work where wind and rain and frost and fire search out its weaknesses. In view of its very nature and the great variety of its proper uses, it should never displace the exterior masonry wall, which in stone, tile, or brick makes the most secure and enduring structure. If the 80 per cent of building in this country, now done of frame, were put into brick, or other durable and fire-resistive materials, it would result in a great economic national gain, people would have better and more substantial houses, and the lumber which everybody needs would be conserved for the legitimate uses to which it is admirably adapted.

There are three possible ways of using face brick in building a wall, determined by the backing up material employed, each of which will be given special attention in the following pages.
