§ 285. Riggs says[203] that the Dakota pray to the spirits of their deceased relatives. [See §§ 67-71.] And in his account of the Assinniboin, Smet says: The Assinniboines esteem greatly a religious custom of assembling once or twice a year around the graves of their immediate relatives. These graves are on scaffolds about 7 or 8 feet above the surface of the ground. The Indians call their dead by name and offer to them meats carefully dressed, which they place beside them. The ceremony of burying the dead is terminated with tears, wailings, howlings, and macerations of all present. They tear the hair, gash the legs, and at last they light the calumet, for that is the Alpha and Omega of every rite. They offer it to the shades of the departed and entreat them not to injure the living. During their ceremonious repasts, in their excursions, and even at a great distance from their graves, they send to the dead puffs of tobacco smoke and burn little pieces of meat as a sacrifice to their memory. § 286. Before consulting the tutelary spirits [see § 34] or addressing the dead, they begin by kindling the sacred fire. This fire must be struck from a flint, or it must reach them mysteriously by lightning, or in some other way. To light the sacred fire with a common fire would be considered among them as a grave and dangerous transgression.[204] METAMORPHOSES AND THE TRANSMIGRATION OF SOULS. § 287. They believe in transformations, such as are described in Ovid, and they think that many of the stars are men and women translated to the heavens. They believe in the transmigration of souls. Some of the medicine men profess to tell of what occurred to them in bodies previously inhabited for at least six generations back. [See §§ 260, 267.] EXHORTATIONS TO ABSENT WARRIORS. § 288. Among the Teton it has been customary for those remaining at home to make songs about the absent warriors, calling them by name, as if they could hear the speakers. This Dakota custom agrees with what has been recorded of the Omaha.[205] Bushotter has told of another Teton custom. The kindred of a slain warrior make songs in his honor, and sing them as they mourn for his death. MYSTERIOUS MEN AND WOMEN. § 289. Lynd says:
