Pow-Wows, or Long Lost Friend, by John George Hoffman, , at sacred-texts.com
A good Remedy for Worms, to be used for men as well as for Cattle:
Mary, God's Mother, traversed the land,
Holding three worms close in her hand;
One was white, the other was black, the third was red.
This must be repeated three times, at the same time stroking the person or animal with the hand; and at the end of each application strike the back of the person or the animal, to wit: at the first application once, at the second application twice, and at the third application three times; and then set the worms a certain time, but not less than three minutes.
