A California Life-Oak.
No tree in the park is a better measure of altitude. In cañons, at an elevation of four thousand, feet you may easily find a tree six or eight feet in diameter; and at the head of a side cañon, three thousand feet higher, up which you can climb in less than two hours, you find the knotty giant dwarfed to a slender shrub, with leaves like those of huckleberry bushes, still bearing acorns, and seemingly contented, forming dense patches of chaparral, on the top of which you may make your bed and sleep softly like a Highlander in heather. About a thousand feet higher it is still smaller, making fringes about a foot high around boulders and along seams in pavements and the brows of cañons, giving hand-holds here and there on cliffs hard to climb. The largest I have measured were from twenty-five to twenty-seven feet in girth, fifty to sixty feet high, and the spread of the limbs was about double the height.
The principal riverside trees are poplar, alder, willow, broad-leaved maple, and Nuttall’s flowering dogwood. The poplar (Populus trichocarpa), often called balm of Gilead from the gum on its buds, is a tall, stately tree, towering above its companions and gracefully embowering the banks of the main streams at an elevation of about four thousand feet. Its abundant foliage turns bright yellow in the fall, and the Indian-summer sunshine sifts through it in delightful tones over the slow-gliding waters when they are at their lowest ebb.
The flowering dogwood is brighter still in these brooding days, for every branch of its broad head is then a brilliant crimson flame. In the spring, when the streams are in flood, it is the whitest of trees, white as a snow bank with its magnificent flowers four to eight inches in width, making a wonderful show, and drawing swarms of moths and butterflies.
The broad-leaved maple is usually found in the coolest boulder-choked cañons, where the streams are gray and white with foam, over which it spreads its branches in beautiful arches from bank to bank, forming leafy tunnels full of soft green light and spray,—favorite homes of the water ousel. Around the glacier lakes, two or three thousand feet higher, the common aspen grows in fringing lines and groves which are brilliantly colored in autumn, reminding you of the color glory of the Eastern woods.
Scattered here and there or in groves the botanist will find a few other trees, mostly small,—the mountain mahogany, cherry, chestnut-oak, laurel, and nutmeg. The California nutmeg (Tumion Californicum) is a handsome evergreen, belonging to the yew family, with pale bark, prickly leaves, fruit like a green-gage plum, and seed like a nutmeg. One of the best groves of it in the park is at the Cascades below Yosemite.
But the noble oaks and all these rock-shading, stream-embowering trees are as nothing amid the vast abounding billowy forests of conifers. During my first years in the Sierra I was ever calling on everybody within reach to admire them, but I found no one half warm enough until Emerson came. I had read his essays, and felt sure that of all men he would best interpret the sayings of these noble mountains and trees. Nor was my faith weakened when I met him in Yosemite. He seemed as serene as a sequoia, his head in the empyrean; and forgetting his age, plans, duties, ties of every sort, I proposed an immeasurable camping trip back in the heart of the mountains. He seemed anxious to go, but considerately mentioned his party. I said: “Never mind. The mountains are calling; run away, and let plans and parties and dragging lowland duties all ‘gang tapsal-teerie’. We’ll go up a cañon singing your own song, ‘Good-by, proud world! I’m going home,’ in divine earnest. Up there lies a new heaven and a new earth; let us go to the show.” But alas, it was too late,—too near the sundown of his life. The shadows were growing long, and he leaned on his friends. His party, full of indoor philosophy, failed to see the natural beauty and fullness of promise of my wild plan, and laughed at it in good-natured ignorance, as if it were necessarily amusing to imagine that Boston people might be led to accept Sierra manifestations of God at the price of rough camping. Anyhow, they would have none of it, and held Mr. Emerson to the hotels and trails.
After spending only five tourist days in Yosemite he was led away, but I saw him two days more; for I was kindly invited to go with the party as far as the Mariposa big trees. I told Mr. Emerson that I would gladly go to the sequoias with him, if he would camp in the grove. He consented heartily, and I felt sure that we would have at least one good wild memorable night around a sequoia camp-fire. Next day we rode through the magnificent forests of the Merced basin, and I kept calling his attention to the sugar pines, quoting his wood-notes, “Come listen what the pine tree saith,” etc., pointing out the noblest as kings and high priests, the most eloquent and commanding preachers of all the mountain forests, stretching forth their century-old arms in benediction over the worshiping congregations crowded about them. He gazed in devout admiration, saying but little, while his fine smile faded away.
