The middle Sierras fall off abruptly eastward toward the high valleys. Peaks of the fourteen thousand class, belted with sombre swathes of pine, rise almost directly from the bench lands with no foothill approaches. At the lower edge of the bench or mesa the land falls away, often by a fault, to the river hollows, and along the drop one looks for springs or intermittent swampy swales. Here the plant world resembles a little the lake gardens, modified by altitude and the use the town folk put it to for pasture. Here are cress, blue violets, potentilla, and, in the damp of the willow fence-rows, white false asphodels. I am sure we make too free use of this word FALSE in naming plants–false mallow, false lupine, and the like. The asphodel is at least no falsifier, but a true lily by all the heaven-set marks, though small of flower and run mostly to leaves, and should have a name that gives it credit for growing up in such celestial semblance. Native to the mesa meadows is a pale iris, gardens of it acres wide, that in the spring season of full bloom make an airy fluttering as of azure wings. Single flowers are too thin and sketchy of outline to affect the imagination, but the full fields have the misty blue of mirage waters rolled across desert sand, and quicken the senses to the anticipation of things ethereal. A very poet’s flower, I thought; not fit for gathering up, and proving a nuisance in the pastures, therefore needing to be the more loved. And one day I caught Winnenap’ drawing out from mid leaf a fine strong fibre for making snares. The borders of the iris fields are pure gold, nearly sessile buttercups and a creeping-stemmed composite of a redder hue. I am convinced that English-speaking children will always have buttercups. If they do not light upon the original companion of little frogs they will take the next best and cherish it accordingly. I find five unrelated species loved by that name, and as many more and as inappropriately called cowslips.

By every mesa spring one may expect to find a single shrub of the buckthorn, called of old time Cascara sagrada–the sacred bark. Up in the canons, within the limit of the rains, it seeks rather a stony slope, but in the dry valleys is not found away from water borders.

In all the valleys and along the desert edges of the west are considerable areas of soil sickly with alkali-collecting pools, black and evil-smelling like old blood. Very little grows hereabout but thick-leaved pickle weed. Curiously enough, in this stiff mud, along roadways where there is frequently a little leakage from canals, grows the only western representative of the true heliotropes (Heliotropium curassavicum). It has flowers of faded white, foliage of faded green, resembling the “live-for-ever” of old gardens and graveyards, but even less attractive. After so much schooling in the virtues of water-seeking plants, one is not surprised to learn that its mucilaginous sap has healing powers.

Last and inevitable resort of overflow waters is the tulares, great wastes of reeds (Juncus) in sickly, slow streams. The reeds, called tules, are ghostly pale in winter, in summer deep poisonous-looking green, the waters thick and brown; the reed beds breaking into dingy pools, clumps of rotting willows, narrow winding water lanes and sinking paths. The tules grow inconceivably thick in places, standing man-high above the water; cattle, no, not any fish nor fowl can penetrate them. Old stalks succumb slowly; the bed soil is quagmire, settling with the weight as it fills and fills. Too slowly for counting they raise little islands from the bog and reclaim the land. The waters pushed out cut deeper channels, gnaw off the edges of the solid earth.

The tulares are full of mystery and malaria. That is why we have meant to explore them and have never done so. It must be a happy mystery. So you would think to hear the redwinged blackbirds proclaim it clear March mornings. Flocks of them, and every flock a myriad, shelter in the dry, whispering stems. They make little arched runways deep into the heart of the tule beds. Miles across the valley one hears the clamor of their high, keen flutings in the mating weather.

Wild fowl, quacking hordes of them, nest in the tulares. Any day’s venture will raise from open shallows the great blue heron on his hollow wings. Chill evenings the mallard drakes cry continually from the glassy pools, the bittern’s hollow boom rolls along the water paths. Strange and farflown fowl drop down against the saffron, autumn sky. All day wings beat above it hazy with speed; long flights of cranes glimmer in the twilight. By night one wakes to hear the clanging geese go over. One wishes for, but gets no nearer speech from those the reedy fens have swallowed up. What they do there, how fare, what find, is the secret of the tulares.
