SPIDERS.
§ 249. The Teton pray to gray spiders, and to those with yellow legs. When a person goes on a journey and a spider passes, one does not kill it in silence. For should one let it escape, or kill it without prayer, bad consequences must ensue. In the latter case, another spider would avenge the death of his relation. To avoid any such misfortune, when the spider is encountered, the person must say to it, “Iktómi Tuŋkaŋśila, Waʞiŋyaŋ niktepe lo,” i. e., “O Grandfather Spider, the Thunder-beings kill you!” The spider is crushed at once, and his spirit believes what has been told him. His spirit probably tells this to the other spiders, but they can not harm the Thunder-beings. If one thus addresses a spider as he kills it, he will never be bitten by other spiders.
[§ 231.] One of the Dakota myths tells how Unktomi killed himself, causing his limbs to shrivel up till they assumed the appearance of spiders’ limbs.
