"Bucking" pine trees into eight-foot lengths, a cutter wields his chain saw in west ern Alberta. Logs at the Hin ton mill of North Western Pulp & Power, Ltd., form stacks five stories high (be low). Stripped of bark and chipped into pieces the size of a quarter, the wood enters giant pressure cookers to be "digested." Later the pulp is bleached, dried, and cut into sheets. Then it goes to other plants for use in such prod ucts as photographic paper and cardboard.
