One of the greatest lumbering districts in the United States is in the extreme northwestern part. There are forests of redwood, fir, cedar, larch, spruce, and hemlock. Some of the trees are easily 300 feet high and 30 feet in circumference. These forest giants are often free from limbs up to a height of 100 feet from the ground. The state of Washington leads all other states in the production of lumber and shingles. The amount of lumber annually cut from its woods is about 4,000,000,000 feet. The view here suggests what happens to many of these logs. The timber cut in the upper reaches of the Columbia or along its tributaries is hauled to the water's edge and placed in great rafts. The construction of one of these rafts is here beautifully shown. The logs are built up into piles that resemble a whaleback steamer on the Great Lakes. They are held together by heavy chains, and usually several such rafts are floated down the river in a group. The method of loading the logs is suggested by the half dozen that you see on the left. Little engines often furnish the power to drag them on the raft. Horses, hitched to a capstan, are sometimes used. Again, if the logs are not too large, and the rafts are nor too high, the logs may be handled by men with pike poles and cantilever hooks. For days and days these huge rafts glide down the Columbia River towards the Pacific. When they reach the milling city, they are towed inside a great boom where hundreds of other rafts are moored. Nearby are the large sawing and planning mills. Here gang-saws, a number of saws placed side by side in a steel frame, rip them into boards, sawing as many as 20 boards at a single passage.
