In the neighborhood of towns founded by the Spanish Californians, whether this plant is native to the locality or not, one can always find aromatic clumps of yerba buena, the "good herb" (Micromeria douglassii). The virtue of it as a febrifuge was taught to the mission fathers by the neophytes, and wise old dames of my acquaintance have worked astonishing cures with it and the succulent yerba mansa. This last is native to wet meadows and distinguished enough to have a family all to itself.

Where the irrigating ditches are shallow and a little neglected, they choke quickly with watercress that multiplies about the lowest Sierra springs. It is characteristic of the frequenters of water borders near man haunts, that they are chiefly of the sorts that are useful to man, as if they made their services an excuse for the intrusion. The joint-grass of soggy pastures produces edible, nut-flavored tubers, called by the Indians taboose. The common reed of the ultramontane marshes (here Phragmites vulgaris), a very stately, whispering reed, light and strong for shafts or arrows, affords sweet sap and pith which makes a passable sugar.

It seems the secrets of plant powers and influences yield themselves most readily to primitive peoples, at least one never hears of the knowledge coming from any other source. The Indian never concerns himself, as the botanist and the poet, with the plant's appearances and relations, but with what it can do for him.
