Note 213 — LETTER VII

For a description of this plant see our volume xv, pp. 232, 233. It is allied to the Yucca filamentosa of the Southern states, whence its name of "Adam's needle." It is more commonly called silk or bear grass, and its filaments were used for weaving by the Indians of the Columbia, whence it became an article of intertribal trade.
