can fashion with his own hands. The early settlers simply felled 

 the trees and with rude tools piled the logs into strong, substantial 

 cabins and stockades. The same workable feature applies all down 

 the line and into wood- working establishments. The log house of 

 the settler has been replaced by the frame and board house of the 

 present times, simply because it was found how wood could be 

 worked into many convenient forms by machinery. 



Lightness and strength are other merits. Wood weighs less 

 than any other commonly used building material. It can be trans- 

 ported cheaply ; can be lifted and carried without difficulty by work- 

 men, and when placed in a building or structure, does not tend to 

 break it down by its own weight. Even with this merit of lightness 

 it has greater strength, weight for weight, than iron or steel. It 

 not on ^ w ^ carr y heavy loads, but it gives and bends before it 

 breaks, and usually gives warning before an actual fracture occurs. 

 As an example of present application of these combined merits of 

 lightness and strength, it has been found that railroad trestles in 

 some cases when constructed of steel and concrete are too heavy. 

 To carry even the upper portion or deck very strong supports are 

 necessary, even before the weight of the trains or locomotives is con- 

 sidered. 



Wood possesses another advantage which exists in few other 

 materials. This is in connection with heat and cold. We often 

 hear it said that wooden buildings are coolest in summer and warm- 

 est in winter. This is for the very simple reason that wood is a 

 poor conductor of heat, and by the same token a poor conductor of 

 cold. In other words, heat does not readily pass through wood, 

 because it is porous, and the dead air spaces are the best possible 

 non-conductors. Some experiments conducted in Europe showed 

 that a frame house with 7/16 inch clap boards, building paper, 

 sheathing, lath and plaster was equivalent to a 20-inch sandstone 

 wall. Such a wooden wall retains heat much better than a brick 

 wall or any other mineral building material. 



Then there comes a merit which especially appeals to every 

 one, and that is the beauty of wood. The wonderful grain which can 

 be brought out with proper finish, the softness of texture, and the 

 varying effects appeal to every one. Moreover, it is not necessarily 

 the prominently grained woods which make the strongest appeal for 

 beauty, because one tires of extreme effects. Just plain, everyday 

 wood, as it is used in millions of homes, gives continued satisfaction
