Thus accoutred, the Tadibe seizes his magical drum, whose sounds summon the spirits to his will. Its form is round, it has but one bottom, made of reindeer skin, and is more or less decorated with brass rings and other ornaments, according to the wealth or poverty of its possessor. During the ceremony of invocation, the Tadibe is generally assisted by a disciple, more or less initiated in the magic art. They either sit down, or walk about in a circle. The chief sorcerer beats the drum, at first slowly, then with increasing violence, singing at the same time a few words to a mystic melody. The disciple immediately falls in, and both repeat the same monotonous chant. At length the spirits appear, and the consultation is supposed to begin; the Tadibe from time to time remaining silent, as if listening to their answers, and but gently beating his drum, while the assistant continues to sing. Finally, this mute conversation ceases, the song changes into a wild howling, the drum is violently struck, the eye of the Tadibe glows with a strange fire, foam issues from his lips--when suddenly the uproar ceases, and the oracular sentence is pronounced. The Tadibes are consulted not only for the purpose of recovering a strange reindeer, or to preserve the herd from a contagious disorder, or to obtain success in fishing; the Samoïede, when a prey to illness, seeks no other medical advice; and the sorcerer’s drum either scares away the malevolent spirits that cause the malady, or summons others to the assistance of his patient.
