It is to be understood that these paragraphs are not treating upon the superstitions concerning the human hair, as such, but simply of the employment of wigs, which would seem in former days among some of the tribes of the Southwest to have been made of human hair presented by patients who had recovered from sickness or by mourners whose relatives had died.[106] Wigs with masks attached were worn by the Costa Ricans, according to Gabb.[107] Some of the Apache-Yuma men wear long rolls of matted hair behind, which are the thickness of a finger, and two feet or more in length, and composed of old hair mixed with that growing on the head, or are in the form of a wig, made of hair that has been cut off when mourning the dead, to be worn on occasions of ceremony.[108] Observations of the same kind have been made by Speke upon the customs of the people of Africa in his Nile,[109] concerning the Kidi people at the head of the Nile; by Cook, in Hawkesworth's Voyages,[110] speaking of Tahiti, and by Barcia,[111] speaking of Greenland. Sir Samuel Baker describes the peculiar wigs worn by the tribes on Lake Albert Nyanza, formed of the owner's hair and contributions from all sources plastered with clay into a stiff mass.[112] Melchior Diaz reported that the people of Cibola "élèvent dans leurs maisons des animaux velus, grands comme des chiens d'Espagne. Ils les tondent, ils en font des perruques de couleurs." This report was sent by the Viceroy Mendoza to the Emperor Charles V. Exactly what these domesticated animals were, it would be hard to say; they may possibly have been Rocky Mountain sheep,[113] though Mr. Cushing, who has studied the question somewhat extensively, is of the opinion that they may have been a variety of the llama. The Assinaboine used to wear false hair, and also had the custom of dividing their hair into "joints" of an inch or more, marked by a sort of paste of red earth and glue;[114] The Mandan did the same.[115] In this they both resemble the Mohave of the Rio Colorado. "The Algonquins believed also in a malignant Maniton. * * * She wore a robe made of the hair of her victims, for she was the cause of death."[116] The Apache, until within the last twenty years, plucked out the eyelashes and often the eyebrows, but only a few of them still persist in the practice. Kane says that the Winnebagoes "have the custom of pulling out their eyebrows."[117] Herrera says that among the signs by which the Tlascaltecs recognized their gods when they saw them in visions, were "vianle sin cejas, i sin pestañas."[118] MUDHEADS.
