THIS SPEAKS FOR ITSELF This picture shows the great width of clear lumber that can be obtained from Douglas fir timber. Douglas fir produces a very high percentage of absolutely clear lumber. Douglas fir is one of the very few woods which is well adapted to construction throughout, either in the home or commercial structure. For use as sub-sills, joists, studding, and rafters it has strength and durability ; for use as siding it has beauty and durability and holds paint well; as a flooring material it otifers great resistance to wear, and for the interior finish of the home, the panel- ing, baseboards, stairwork, doors, sash, moldings, or other tinish requirements its beauty adapts it admirably. But while filling well the needs of a home-building wood, it is none the less a factory, store, bridge, and general structure wood. Its strength, lightness, and durability are the desired characteristics for these pur- poses. Railroads are large purchasers of Douglas fir for car construction, railroad ties, trestle work, piling, poles, and miscellaneous work. In 1009. when one hundred and twenty-five million ties were purchased, Douglas fir contributed over nine million of tlicni, and would furnish many more but for the long haul to the principal tie markets. Southern pine furnished twenty- one million and the oaks fifty-seven million. The same year twenty-five thousand poles were cut from Douglas fir. The cedars, however, are preferred for this use because of their extreme durability. Xo data are available on the amount of piling dri\en annually, but Douglas fir is exceeded only by the Southern pines as a piling wood. The four requisites of a good piling are straightness, strength, length, and durability. Douglas fir is nearly always "pencil" straight, amply strong, clear length up to one hundred and fifty feet, if desired, and is the equal in d
