This formula is taken from the manuscript book of Gatigwanasti, now dead, and must therefore be explained from general analogy. The ailment is described as “pains moving about in the teeth”--that is, affecting several teeth simultaneously--and appears to be neuralgia. The disease spirit is called “the intruder” and “the tormentor” and is declared to be a mere worm (tsgâ´ya), which has wrapped itself around the base of the tooth. This is the regular toothache theory. The doctor then calls upon the Red Spider of the Sunland to let down the red threads from above, along the red path, and to take up the intruder, which is just what the spider eats. The same prayer is addressed in turn to the Blue Spider in the north, the Black Spider in the west and the White Spider above (galû[n]´lati). It may be stated here that all these spirits are supposed to dwell above, but when no point of the compass is assigned, galû[n]´lati is understood to mean directly overhead, but far above everything of earth. The dweller in this overhead galû[n]´lati may be red, white, or brown in color. In this formula it is white, the ordinary color assigned spirits dwelling in the south. In another toothache formula the Squirrel is implored to take the worm and put it between the forking limbs of a tree on the north side of the mountain. Following each supplication to the spider is another addressed to the Ancient White, the formulistic name for fire. The name refers to its antiquity and light-giving properties and perhaps also to the fact that when dead it is covered with a coat of white ashes. In those formulas in which the hunter draws omens from the live coals it is frequently addressed as the Ancient Red. The directions are not explicit and must be interpreted from analogy. “Laying on the hands” refers to pressing the thumb against the jaw over the aching tooth, the hand having been previously warmed over the fire, this being a common method of treating toothache. The other method suggested is to blow upon the spot (tooth or outside of jaw?) a decoction of an herb described rather vaguely as “yellow-rooted grass” either through a tube or from the mouth of the operator. Igawĭ´, a toothache specialist, treats this ailment either by pressure with the warm thumb, or by blowing tobacco smoke from a pipe placed directly against the tooth. Hominy and fermented corn gruel (kanâhe´na) are prohibited for the regular term of four nights, or, as we are accustomed to say, four days, and special emphasis is laid upon the gruel tabu.
