The yellow pine (Pinus ponderosa) is surpassed in size and nobleness of port only by its kingly companion. Full-grown trees in the main forest where it is associated with the sugar pine, are about one hundred and seventy-five feet high, with a diameter of five to six feet, though much larger specimens may easily be found. The largest I ever measured was little over eight feet in diameter four feet above the ground, and two hundred and twenty feet high. Where there is plenty of sunshine and other conditions are favorable, it is a massive symmetrical spire, formed of a strong straight shaft clad with innumerable branches, which are divided again and again into stout branchlets laden with bright shining needles and green or purple cones. Where the growth is at all close half or more of the trunk is branchless. The species attains its greatest size and most majestic form in open groves on the deep, well-drained soil of lake basins at an elevation of about four thousand feet. There nearly all the old trees are over two hundred feet high, and the heavy, leafy, much-divided branches sumptuously clothe the trunk almost to the ground. Such trees are easily climbed, and in going up the winding stairs of knotty limbs to the top you will gain a most telling and memorable idea of the height, the richness and intricacy of the branches, and the marvelous abundance and beauty of the long shining elastic foliage. In tranquil weather, you will see the firm outstanding needles in calm content, shimmering and throwing off keen minute rays of light like lances of ice; but when heavy winds are blowing, the strong towers bend and wave in the blast with eager wide-awake enthusiasm, and every tree in the grove glows and flashes in one mass of white sunfire.
Both the yellow and sugar pines grow rapidly on good soil where they are not crowded. At the age of a hundred years they are about two feet in diameter and a hundred or more high. They are then very handsome, though very unlike: the sugar pine, lithe, feathery, closely clad with ascending branches; the yellow, open, showing its axis from the ground to the top, its whorled branches but little divided as yet, spreading and turning up at the ends with magnificent tassels of long stout bright needles, the terminal shoot with its leaves being often three or four feet long and a foot and a half wide, the most hopeful looking and the handsomest tree-top in the woods. But instead of increasing, like its companion, in wildness and individuality of form with age, it becomes more evenly and compactly spiry. The bark is usually very thick, four to six inches at the ground, and arranged in large plates, some of them on the lower part of the trunk four or five feet long and twelve to eighteen inches wide, forming a strong defense against fire. The leaves are in threes, and from three inches to a foot long. The flowers appear in May: the staminate pink or brown, in conspicuous clusters two or three inches wide; the pistillate crimson, a fourth of an inch wide, and mostly hidden among the leaves on the tips of the branchlets. The cones vary from about three to ten inches in length, two to five in width, and grow in sessile outstanding clusters near the ends of the upturned branchlets.
Being able to endure fire and hunger and many climates this grand tree is widely distributed: eastward from the coast across the broad Rocky Mountain ranges to the Black Hills of Dakota, a distance of more than a thousand miles, and southward from British Columbia, near latitude 51°, to Mexico, about fifteen hundred miles. South of the Columbia River it meets the sugar pine, and accompanies it all the way down along the Coast and Cascade mountains and the Sierra and southern ranges to the mountains of the peninsula of Lower California, where they find their southmost homes together. Pinus ponderosa is extremely variable, and much bother it gives botanists who try to catch and confine the unmanageable proteus in two or a dozen species,—Jeffreyi, deflexa, Apacheca latifolia, etc. But in all its wanderings, in every form, it manifests noble strength. Clad in thick bark like a warrior in mail, it extends its bright ranks over all the high ranges of the wild side of the continent: flourishes in the drenching fog and rain of the northern coast at the level of the sea, in the snow-laden blasts of the mountains, and the white glaring sunshine of the interior plateaus and plains, on the borders of mirage-haunted deserts, volcanoes, and lava beds, waving its bright plumes in hot winds undaunted, blooming every year for centuries, and tossing big ripe cones among the cinders and ashes of nature’s hearths.
