In one of the numerous variants of this story[162] the heroine is sent by her husband's mother to the Baba Yaga's, and the advice which saves her comes from her husband. The Baba Yaga goes into another room "in order to sharpen her teeth," and while she is engaged in that operation the girl escapes, having previously--by the advice of the Cat, to which she had given a lump of butter--spat under the threshold. The spittle answers for her in her absence, behaving as do, in other folk-tales, drops of blood, or rags dipped in blood, or apples, or eggs, or beans, or stone images, or wooden puppets.[163] The magic comb and towel, by the aid of which the girl effects her escape, constantly figure in Skazkas of this class, and always produce the required effect. A brush, also, is frequently introduced, from each bristle of which springs up a wood. In one story, however, the brush gives rise to mountains, and a _golik_, or bath-room whisk, turns into a forest. The towel is used, also, for the purpose of constructing or annihilating a bridge. Similar instruments are found in the folk-tales of every land, whether they appear as the brush, comb, and mirror of the German water-sprite;[164] or the rod, stone, and pitcher of water of the Norse Troll;[165] or the knife, comb, and handful of salt which, in the Modern Greek story, save Asterinos and Pulja from their fiendish mother;[166] or the twig, the stone, and the bladder of water, found in the ear of the filly, which saves her master from the Gaelic giant;[167] or the brush, comb, and egg, the last of which produces a frozen lake with "mirror-smooth" surface, whereon the pursuing Old Prussian witch slips and breaks her neck;[168] or the wand which causes a river to flow and a mountain to rise between the youth who waves it and the "wicked old Rákshasa" who chases him in the Deccan story;[169] or the handful of earth, cup of water, and dry sticks and match, which impede and finally destroy the Rákshasa in the almost identical episode of Somadeva's tale of "The Prince of Varddhamána."[170]
