More widely distributed than any other western tree, and of greatest economic importance. Occurs native from British Columbia south to southern California, Arizona and New Mexico, east to Dakota, Kansas, and Texas. Attains best growth in the Sierras. Maximum size 7' x 200', averages much less, depending on region. The wood is soft, moderately strong and easily worked. Used for ties, props, poles, house construction, sash and doors, boxes, matches. See Baker white pine board adjacent. Although this tree is a true yellow pine, its wood often approaches true white pine in appearance and technical qualities. For this reason and because the term "yellow pine" commonly infers a very resinous and rather hard wood, producers prefer to call it western white pine, Baker white pine, California white pine, Arizona white pine, etc., depending on the region of growth. Foresters and botanists call it Western Yellow Pine.

• 135-3: from Deschutes Valley, Oregon. - Known to the trade as Western White Pine and also Deschutes White Pine. This pine is commonly referred to as "White Pine" by lumbermen, because it is not as hard, heavy, and pitchy as the yellow pines of the Gulf Coast, and because the wood is softer, more easily worked, lighter in color and weight, and closely resembles a true white pine. Wood from the Deschutes region is particularly of good quality--soft, straight- grained, and light. It is used for planing mill products, sash and doors, construction, finish, ties, props.

• 131-2: BIRDSEYE PONDEROSA PINE: This curious and interesting type of figure is found occasionally in this pine. The cause of the figure is not definitely known in all cases but, in some cases, is caused by a "gall midge." The insect apparently punctures and stimulates the cambium to produce a malformation that may persist throughout the life of the tree. The growth ring becomes indented and thin bark becomes enclosed during the early period in the tree's life. Though not at all a general phenomenon, boards of this character are not uncommon. This type of birdseye has an entirely different origin than the birdseye in hard maple and in redwood. Gift of Hobart Estate Co., Hobart Mills, Calif.
