Not even in the great maple woods of Canada have I seen trees either as large or with so much striking, picturesque character. It is widely distributed throughout western Washington, but is never found scattered among the conifers in the dense woods. It keeps together mostly in magnificent groves by itself on the damp levels along the banks of streams or lakes where the ground is subject to overflow. In such situations it attains a height of seventy-five to a hundred feet and a diameter of four to eight feet. The trunk sends out large limbs toward its neighbors, laden with long drooping mosses beneath and rows of ferns on their upper surfaces, thus making a grand series of richly ornamented interlacing arches, with the leaves laid thick overhead, rendering the underwood spaces delightfully cool and open. Never have I seen a finer forest ceiling or a more picturesque one, while the floor, covered with tall ferns and rubus and thrown into hillocks by the bulging roots, matches it well. The largest of these maple groves that I have yet found is on the right bank of the Snoqualmie River, about a mile above the falls. The whole country hereabouts is picturesque, and interesting in many ways, and well worthy a visit by tourists passing through the Sound region, since it is now accessible by rail from Seattle.
Looking now at the forests in a comprehensive way, we find in passing through them again and again from the shores of the Sound to their upper limits, that some portions are much older than others, the trees much larger, and the ground beneath them strewn with immense trunks in every stage of decay, representing several generations of growth, everything about them giving the impression that these are indeed the "forests primeval," while in the younger portions, where the elevation of the ground is the same as to the sea level and the species of trees are the same as well as the quality of the soil, apart from the moisture which it holds, the trees seem to be and are mostly of the same age, perhaps from one hundred to two or three hundred years, with no gray-bearded, venerable patriarchs--forming tall, majestic woods without any grandfathers.
When we examine the ground we find that it is as free from those mounds of brown crumbling wood and mossy ancient fragments as are the growing trees from very old ones. Then perchance, we come upon a section farther up the slopes towards the mountains that has no trees more than fifty years old, or even fifteen or twenty years old. These last show plainly enough that they have been devastated by fire, as the black, melancholy monuments rising here and there above the young growth bear witness. Then, with this fiery, suggestive testimony, on examining those section whose trees are a hundred years old or two hundred, we find the same fire records, though heavily veiled with mosses and lichens, showing that a century or two ago the forests that stood there had been swept away in some tremendous fire at a time when rare conditions of drouth made their burning possible. Then, the bare ground sprinkled with the winged seed from the edges of the burned district, a new forest sprang up, nearly every tree starting at the same time or within a few years, thus producing the uniformity of size we find in such places; while, on the other hand, in those sections of ancient aspect containing very old trees both standing and fallen, we find no traces of fire, nor from the extreme dampness of the ground can we see any possibility of fire ever running there.
Fire, then, is the great governing agent in forest distribution and to a great extent also in the conditions of forest growth. Where fertile lands are very wet one half the year and very dry the other, there can be no forests at all. Where the ground is damp, with drouth occurring only at intervals of centuries, fine forests may be found, other conditions being favorable. But it is only where fires never run that truly ancient forests of pitchy coniferous trees may exist. When the Washington forests are seen from the deck of a ship out in the middle of the sound, or even from the top of some high, commanding mountain, the woods seem everywhere perfectly solid. And so in fact they are in general found to be. The largest openings are those of the lakes and prairies, the smaller of beaver meadows, bogs, and the rivers; none of them large enough to make a distinct mark in comprehensive views.
Of the lakes there are said to be some thirty in King's County alone;the largest, Lake Washington, being twenty-six miles long and four miles wide. Another, which enjoys the duckish name of Lake Squak, is about ten miles long. Both are pure and beautiful, lying imbedded in the green wilderness. The rivers are numerous and are but little affected by the weather, flowing with deep, steady currents the year round. They are short, however, none of them drawing their sources from beyond the Cascade Range. Some are navigable for small steamers on their lower courses, but the openings they make in the woods are very narrow, the tall trees on their banks leaning over in some places, making fine shady tunnels.
