The shells are thin and may be crushed between the thumb and finger. The kernels are white, becoming brown by roasting, and are sweet to every palate, being eaten by birds, squirrels, dogs, horses, and men. Perhaps less than one bushel in a thousand of the whole crop is ever gathered. Still, besides supplying their own wants, in times of plenty the Indians bring large quantities to market; then they are eaten around nearly every fireside in the State, and are even fed to horses occasionally instead of barley.

      Of other trees growing on the Sierra, but forming a very small part of the general forest, we may briefly notice the following:

      Chamœcyparis Lawsoniana is a magnificent tree in the coast ranges, but small in the Sierra. It is found only well to the northward along the banks of cool streams on the upper Sacramento toward Mount Shasta. Only a few trees of this species, as far as I have seen, have as yet gained a place in the Sierra woods. It has evidently been derived from the coast range by way of the tangle of connecting mountains at the head of the Sacramento Valley.

      In shady dells and on cool stream banks of the northern Sierra we also find the Yew (Taxus brevifolia).

      The interesting Nutmeg Tree (Torreya California) is sparsely distributed along the western flank of the range at an elevation of about 4000 feet, mostly in gulches and cañons. It is a small, prickly leaved, glossy evergreen, like a conifer, from twenty to fifty feet high, and one to two feet in diameter. The fruit resembles a green-gage plum, and contains one seed, about the size of an acorn, and like a nutmeg, hence the common name. The wood is fine-grained and of a beautiful, creamy yellow color like box, sweet-scented when dry, though the green leaves emit a disagreeable odor.

      Betula occidentalis, the only birch, is a small, slender tree restricted to the eastern flank of the range along stream-sides below the pine-belt, especially in Owen's Valley.

      Alder, Maple, and Nuttall's Flowering Dogwood make beautiful bowers over swift, cool streams at an elevation of from 3000 to 5000 feet, mixed more or less with willows and cottonwood; and above these in lake basins the aspen forms fine ornamental groves, and lets its light shine gloriously in the autumn months.

      The Chestnut Oak (Quercus densiflora) seems to have come from the coast range around the head of the Sacramento Valley, like the Chamœcyparis, but as it extends southward along the lower edge of the main pine-belt it grows smaller until it finally dwarfs to a mere chaparral bush. In the coast mountains it is a fine, tall, rather slender tree, about from sixty to seventy-five feet high, growing with the grand Sequoia sempervirens, or Redwood. But unfortunately it is too good to live, and is now being rapidly destroyed for tanbark.

      Besides the common Douglas Oak and the grand Quercus Wislizeni of the foot-hills, and several small ones that make dense growths of chaparral, there are two mountain-oaks that grow with the pines up to an elevation of about 5000 feet above the sea, and greatly enhance the beauty of the yosemite parks. These are the Mountain Live Oak and the Kellogg Oak, named in honor of the admirable botanical pioneer of California. Kellogg's Oak (Quercus Kelloggii) is a firm, bright, beautiful tree, reaching a height of sixty feet, four to seven feet in diameter, with wide-spreading branches, and growing at an elevation of from 3000 to 5000 feet in sunny valleys and flats among the evergreens, and higher in a dwarfed state. In the cliff-bound parks about 4000 feet above the sea it is so abundant and effective it might fairly be called the Yosemite Oak. The leaves make beautiful masses of purple in the spring, and yellow in ripe autumn; while its acorns are eagerly gathered by Indians, squirrels, and woodpeckers. The Mountain Live Oak (Q. Chrysolepis) is a tough, rugged mountaineer of a tree, growing bravely and attaining noble dimensions on the roughest earthquake taluses in deep cañons and yosemite valleys. The trunk is usually short, dividing near the ground into great, wide-spreading limbs, and these again into a multitude of slender sprays, many of them cord-like and drooping to the ground, like those of the Great White Oak of the lowlands (Q. lobata). The top of the tree where there is plenty of space is broad and bossy, with a dense covering of shining leaves, making delightful canopies, the complicated system of gray, interlacing, arching branches as seen from beneath being exceedingly rich and picturesque. No other tree that I know dwarfs so regularly and completely as this under changes of climate due to changes in elevation. At the foot of a cañon 4000 feet above the sea you may find magnificent specimens of this oak fifty feet high, with craggy, bulging trunks, five to seven feet in diameter, and at the head of the cañon, 2500 feet higher, a dense, soft, low, shrubby growth of the same species, while all the way up the cañon between these extremes of size and habit a perfect gradation may be traced. The largest I have seen was fifty feet high, eight feet in diameter, and about seventy-five feet in spread. The trunk was all knots and buttresses, gray like granite, and about as angular and irregular as the boulders on which it was growing--a type of steadfast, unwedgeable strength.

       The Douglas Squirrel

       Table of Contents

      (Sciurus Douglasii)

      THE Douglas Squirrel is by far the most interesting and influential of the California sciuridæ, surpassing every other species in force of character, numbers, and extent of range, and in the amount of influence he brings to bear upon the health and distribution of the vast forests he inhabits.

      Go where you will throughout the noble woods of the Sierra Nevada, among the giant pines and spruces of the lower zones, up through the towering Silver Firs to the storm-bent thickets of the summit peaks, you everywhere find this little squirrel the master-existence. Though only a few inches long, so intense is his fiery vigor and restlessness, he stirs every grove with wild life, and makes himself more important than even the huge bears that shuffle through the tangled underbrush beneath him. Every wind is fretted by his voice, almost every bole and branch feels the sting of his sharp feet. How much the growth of the trees is stimulated by this means it is not easy to learn, but his action in manipulating their seeds is more appreciable. Nature has made him master forester and committed most of her coniferous crops to his paws. Probably over fifty per cent. of all the cones ripened on the Sierra are cut off and handled by the Douglas alone, and of those of the Big Trees perhaps ninety per cent. pass through his hands: the greater portion is of course stored away for food to last during the winter and spring, but some of them are tucked separately into loosely covered holes, where some of the seeds germinate and become trees. But the Sierra is only one of the many provinces over which he holds sway, for his dominion extends over all the Redwood Belt of the Coast Mountains, and far northward throughout the majestic forests of Oregon, Washington, and British Columbia. I make haste to mention these facts, to show upon how substantial a foundation the importance I ascribe to him rests.

      The Douglas is closely allied to the Red Squirrel or Chickaree of the eastern woods. Ours may be a lineal descendant of this species, distributed westward to the Pacific by way of the Great Lakes and the Rocky Mountains, and thence southward along our forested ranges. This view is suggested by the fact that our species becomes redder and more Chickaree-like in general, the farther it is traced back along the course indicated above. But whatever their relationship, and the evolutionary forces that have acted upon them, the Douglas is now the larger and more beautiful animal.

      From the nose to the root of the tail he measures about eight inches; and his tail, which he so effectively uses in interpreting his feelings, is about six inches in length. He wears dark bluish-gray over the back and half-way down the sides, bright buff on the belly, with a stripe of dark gray, nearly black, separating the upper and under colors; this dividing stripe, however, is not very sharply defined. He has long black whiskers, which gives him a rather fierce look when observed closely, strong claws, sharp as fish-hooks, and the brightest of bright eyes, full of telling speculation.

      A King's River Indian told me that they call him "Pillillooeet," which, rapidly pronounced with the first syllable heavily accented, is not unlike the lusty exclamation he utters on his way up a tree when excited. Most mountaineers in California call him the Pine Squirrel; and when I asked an old trapper whether he knew our little forester, he replied with brightening countenance: "Oh, yes, of course I know him; everybody knows
