Then there was artemisia, romero, azalea, the blue-eyed grass of our meadows, upon an infusion of which fever patients can subsist for days, and elder, potent against spells, and there was Virgin's bower, which brought us back to the patio, for a great heap of it lay on the roof of the gallery, contesting the space there with the yellow banksia roses. I had supposed, until the Señora Echivarra mentioned it, that its purpose was purely ornamental, but I was to learn that it had come into the garden as yerba de chivato about the time the barbed-wire fences of the gringo began to make a remedy for cuts indispensable to the ranchero who valued the appearance of his live stock. When the eye, travelling along its twisty stems and twining leaf-stalks, came to a clump of yarrow growing at the root of it I began at once to suspect the whole garden. Was not the virtue of yarrow known even to the Greeks?

There was thyme flowering in the damp corner beyond the dripping faucet, and pot-marigold, lavender, rosemary, and lemon verbena, all plants that grow deep into the use and remembrance of man.

No friend of our race, not even the dog, has been more faithful. The stock of these had come overseas from Spain—were not the Phœnicians credited with introducing the pomegranate into Hispaniola?—and thence by way of the Missions.

All the borders of Dona Ina's garden were edged with rosy thrift, a European variety; and out on the headlands, a mile away, a paler, native cousin of it bloomed gaily with beach asters and yellow sand verbenas, but there was no one who knew by what winds, what communicating rootlets, they had exchanged greetings.

Observation, travelling by way of the borders, came to the datura, which was to set the conversation off again, this time not of plants curative, but hurtful. We knew of the stupefying effects of the bruised pods and roots of this species, and—this was my contribution—how the Paiute Indians used to administer the commoner variety, called main-oph-weep, to their warriors to produce the proper battle frenzy, and especially to young women about to undergo the annual ordeal of the "Dance of Marriageable Maidens."

Every year, at the spring gathering of the tribes, the maidens piled their dowries in a heap, and for three days, fasting, danced about it. If they fell or fainted, it was a sure sign they were not yet equal to the duties of housekeeping and childbearing; but I had had Paiute women tell me that they would never have endured the trial without a mild decoction of main-oph-weep.

"It was different with us," insisted Dona Ina; "many a time we have danced the sun up over the mountain, and been ready to begin again the next evening...." But I wished to talk of the properties of plants, not of young ladies.

The mystery of poison plants oppressed me. One may understand how a scorpion stings in self-protection, but what profit has the "poison oak" of its virulence? It is not oak at all, but Rhus trilobata, and in the spring whole hillsides are enlivened by the shining bronze of its young foliage, or made crimson in September. But the pollen that floats from it in May in clouds, the sticky sap, or even the acrid smoke from the clearing where it is being exterminated, is an active poison to the human skin, though I had not heard that any animal suffered similarly. Dona Ina opined that there was never an evil plant let loose in the gardens of the Lord but the remedy was set to grow beside it. A wash of manzanita tea, Grindelia, or even buckthorn, she insisted, was excellent for poison oak. Best of all was a paste of pounded "soap root." She knew a plant, too, which was corrective of the form of madness induced by the "loco" weed, whose pale foliage and delicately tinted, bladdery pods may be found always about the borders of the chaparral. For the convulsions caused by wild parsnip there was the wonder-working yerba del pasmo. This she knew also as a specific for snake-bite and tetanus. So greatly was it valued by mothers of families in the time of the Spanish Occupation, that when a clearing was made for a house and patio, in any country where it grew, a plant or two was always left standing. But it was not until I had looked for it, where she said I would find it between the oleander and the lemon verbena, that I recognised the common "grease-wood," the chamise of the mesa country.

"But were there no plants, Dona Ina, which had another meaning, flowers of affection, corrective to the spirit?"

"Angelica," she considered doubtfully. Young maids, on occasions of indecision, would pin a sprig of it across their bosoms, she said, and after they had been to church would find their doubts resolved; and there was yarrow, which kept your lover true, particularly if you plucked it with the proper ceremony from a young man's grave.
