As to the extent of these evergreen forests, they may be said to cover West Washington with almost unbroken continuity, though they vary in density and the size of the trees, some tracts containing little or no mill-timber. In my travels, which were, of course, quite limited, I saw no forests which answered the usual unqualified descriptions, except in the Snoqualmie Valley, and here they far exceeded my expectation, as will be shown in the detailed description, given hereafter, of the country lying along the line of the Seattle, Lake Shore & Eastern Railway. The finest forests lie between Puget Sound and the crest of the Cascade Mountains, though even in this area there are variations. And after all the chopping and sawing--of which more will be told later--the forests as yet show but little diminution. East of the Cascade Range the forests are smaller, and confined to the mountain sides. There are some narrow belts of pine along the northern edge of the Great Plain of the Columbia, which furnish a little lumber for local uses; but these will soon be worked out. The mountain rim lying along the Canada line is said to be covered with forest, some of it heavy. The Douglas Fir, the Yellow Pine, the White Pine, and the Larch are all to be found there. There are also skirts of the same timber along the Spokane River. And, at wide intervals, there are strips and bunches of scrubby yellow pine on the Great Plain, which is, however, generally treeless. The spurs and ridges of the Blue Mountains are thinly covered with small pines and larches. There are some areas of mill-timber on the east and southeast flanks of the Cascade Mountains. [Sidenote: Range for horses and cattle.] The flora of the great plateau presents a strange appearance to the traveler. The vegetation is short and scanty, the chief growth being the "sage-brush," a dwarfish, dead-looking shrub, with a hard, crooked stem, of no value as forage, but which is sometimes used for fuel when nothing else is to be had. There are said to be some medicinal, and also some edible, plants; but the only thing of any value is the dry, thin, short, bunch grass which furnishes a fattening food for horses and cattle; though many acres are required to support an animal, and close grazing is rapidly destroying this resource. Indeed, the tract is so barren and desert-like in appearance that in the geographies of my boyhood it was put down as a part of the Great American Desert. And yet, as will be seen hereafter, this is probably the most productive upland in America. LUMBERING. Lumbering was the first industry of Washington Territory. Even food was imported for a time. Logging began on Puget Sound, and went up such streams as afforded transportation and water-power. Steam-power soon became the chief reliance for sawing, but water-power will be largely used when the railroads penetrate inland.
