The Durability of Sugar Pine

IN CALIFORNIA where Sugar Pine has been used since before the Days of '49, no one ever I raises the question of its durability. The ancient landmarks are eloquent evidence. Hand sawed planks and split shakes show no traces of decay after three-quarters of a century of exposure to the weather without adrop of paint or preservative.

Nor have these cabins of the pioneers been favored by climate. In the high altitudes of the Sierras, where the '49ers and pioneer ranchers lived and built these rude houses, the winters are long and the snows are deep.

SUGAR PINE being a true White Pine, botanically and physically, has long life as well as the characteristic virtues of easy-working and freedom'from distortion. It is the ideal wood for exposed sash and doors, siding, moulding and trim.
