Note 197 — Chapter 32
Reading edition
See the Castañeda narration, p. 326, post; and compare the Rudo Ensayo (ca. 1763), p. 64, 1863, which says: "Mago, in the Opata language, is a small tree, very green, luxuriant, and beautiful to the eye; but it contains a deadly juice which flows upon making a slight incision in the bark. The natives rub their arrows with it, and for this reason they call it arrow herb; but at present they use very little."
