The Western arbor-vitae[24] (Thuja gigantea) grows to a size truly gigantic on low rich ground. Specimens ten feet in diameter and a hundred and forty feet high are not at all rare. Some that I have heard of are said to be fifteen and even eighteen feet thick. Clad in rich, glossy plumes, with gray lichens covering their smooth, tapering boles, perfect trees of this species are truly noble objects and well worthy the place they hold in these glorious forests. It is of this tree that the Indians make their fine canoes.
Of the other conifers that are so happy as to have place here, there are three firs, three or four pines, two cypresses, a yew, and another spruce, the Abies Pattoniana[25]. This last is perhaps the most beautiful of all the spruces, but, being comparatively small and growing only far back on the mountains, it receives but little attention from most people. Nor is there room in a work like this for anything like a complete deion of it, or of the others I have just mentioned. Of the three firs, one (Picea grandis)[26], grows near the coast and is one of the largest trees in the forest, sometimes attaining a height of two hundred and fifty feet. The timber, however, is inferior in quality and not much sought after while so much that is better is within reach. One of the others (P.amabilis, var. nobilis) forms magnificent forests by itself at a height of about three thousand to four thousand feet above the sea.
The rich plushy, plumelike branches grow in regular whorls around the trunk, and on the topmost whorls, standing erect, are the large, beautiful cones. This is far the most beautiful of all the firs. In the Sierra Nevada it forms a considerable portion of the main forest belt on the western slope, and it is there that it reaches its greatest size and greatest beauty. The third species (P. subalpina)
forms, together with Abies Pattoniana, the upper edge of the timberline on the portion of the Cascades opposite the Sound. A
thousand feet below the extreme limit of tree growth it occurs in beautiful groups amid parklike openings where flowers grow in extravagant profusion.
The pines are nowhere abundant in the State. The largest, the yellow pine (Pinus ponderosa), occurs here and there on margins of dry gravelly prairies, and only in such situations have I yet seen it in this State. The others (P. monticola and P. contorta) are mostly restricted to the upper slopes of the mountains, and though the former of these two attains a good size and makes excellent lumber, it is mostly beyond reach at present and is not abundant. One of the cypresses (Cupressus Lawsoniana)[27] grows near the coast and is a fine large tree, clothed like the arbor-vitae in a glorious wealth of flat, feathery branches. The other is found here and there well up toward the edge of the timberline. This is the fine Alaska cedar (C.
Nootkatensis), the lumber from which is noted for its durability, fineness of grain, and beautiful yellow color, and for its fragrance, which resembles that of sandalwood. The Alaska Indians make their canoe paddles of it and weave matting and coarse cloth from the fibrous brown bark.
Among the different kinds of hardwood trees are the oak, maple, madrona, birch, alder, and wild apple, while large cottonwoods are common along the rivers and shores of the numerous lakes.
The most striking of these to the traveler is the Menzies arbutus, or madrona, as it is popularly called in California. Its curious red and yellow bark, large thick glossy leaves, and panicles of waxy-looking greenish-white urn-shaped flowers render it very conspicuous. On the boles of the younger trees and on all the branches, the bark is so smooth and seamless that it does not appear as bark at all, but rather the naked wood. The whole tree, with the exception of the larger part of the trunk, looks as though it had been thoroughly peeled. It is found sparsely scattered along the shores of the Sound and back in the forests also on open margins, where the soil is not too wet, and extends up the coast on Vancouver Island beyond Nanaimo. But in no part of the State does it reach anything like the size and beauty of proportions that it attains in California, few trees here being more than ten or twelve inches in diameter and thirty feet high. It is, however, a very remarkable-looking object, standing there like some lost or runaway native of the tropics, naked and painted, beside that dark mossy ocean of northland conifers. Not even a palm tree would seem more out of place here.
The oaks, so far as my observation has reached, seem to be most abundant and to grow largest on the islands of the San Juan and Whidbey Archipelago. One of the three species of maples that I have seen is only a bush that makes tangles on the banks of the rivers. Of the other two one is a small tree, crooked and moss-grown, holding out its leaves to catch the light that filters down through the close-set spires of the great spruces. It grows almost everywhere throughout the entire extent of the forest until the higher slopes of the mountains are reached, and produces a very picturesque and delightful effect; relieving the bareness of the great shafts of the evergreens, without being close enough in its growth to hide them wholly, or to cover the bright mossy carpet that is spread beneath all the dense parts of the woods.
The other species is also very picturesque and at the same time very large, the largest tree of its kind that I have ever seen anywhere.
