Dr. Hoffman reports that among the Hualpai, living on the western border of the Colorado plateau, Arizona, some persons appeared as if they had been tattooed in vertical bands from the forehead to the waist, but upon closer examination it was found that dark and light bands of the natural skin were produced in the following manner: When a deer or an antelope had been killed the blood was rubbed over the face and breast, after which the spread and curved fingers were scratched downward from the forehead over the face and breast, thus removing some of the blood; that remaining soon dried and gave the appearance of black stripes. The exposed portion of the skin retained the natural dark-tanned color, while that under the coating of coagulated blood became paler by being protected against the light and air. These persons did not wash off the marks and after a while the blood began to drop off by desquamation, leaving lighter spots and lines which for a week or two appear like tattoo marks. Similar streaks of blood have been held to have originated tattoo designs in several parts of the world to record success in hunting or in war, but such evolution does not appear to have resulted from the transient decoration in the case mentioned. It is well known that the meal of maize called kunque is yet commonly used by the Zuñi for ceremonial coloration of their own persons and of objects used in their religious rites. Hoddentin is less familiarly known. It is the pollen of the tule, which is a variety of cat-tail rush growing in all the ponds of the southwestern parts of the United States. It is a yellow powder with which small buckskin bags are filled and those bags then attached to the belts of Apache warriors. They are also worn as amulets by members of the tribe. In dances for the cure of sickness the shaman applied the powder to the forehead of the patient, then to his breast in the figure of a cross; next he sprinkles it in a circle around his couch, then on the heads of the chanters and the assembled friends of the patient, and lastly upon his own head and into his own mouth. Everard F. im Thurn (_c_) gives the following details concerning British Guiana: The dyes used by the Indians to paint their own bodies, and occasionally to draw patterns on their implements, are red faroah, purple caraweera, blue-black lana, white felspathic clay and, though very rarely, a yellow vegetable dye of unknown origin. Faroah is the deep red pulp around the seed of a shrub (_Bixa orellana_) which grows wild on the banks of some of the rivers, and is cultivated by the Indians in their clearings. It is mixed with a large quantity of oil. When it is to be used either a mass of it is taken in the palm of the hand and rubbed over the skin or other surface to be painted, or a pattern of fine lines is drawn with it by means of a stick used as a pencil.
