Dr. Haas, in his interesting little volume of folk-lore from the island of Rügen, in the Baltic, records some curious tales about the birth of children. The following practice of the children in that portion of Germany is significant: "Little white and black smooth stones, found on the shore, are called 'stork-stones.' These the children are wont to throw backwards over their heads, asking, at the same time, the stork to bring them a little brother or sister" (466 a. 144). This recalls vividly the old Greek deluge-myth, in which we are told, that, after the Flood, Deucalion was ordered to cast behind him the "bones of his mother." This he interpreted to mean the "stones," which seemed, as it were, the "bones" of "mother-earth." So he and his wife Pyrrha picked up some stones from the ground and cast them over their shoulders, whereupon those thrown by Deucalion became men, those thrown by Pyrrha, women. Here belongs, also, perhaps, the Wallachian custom, mentioned by Mr. Sessions (who thinks it was "probably to keep evil spirits away"), in accordance with which "when a child is born every one present throws a stone behind him." On the island of Rügen erratic blocks on the seashore are called _Adeborsteine_, "stork-stones," and on such a rock or boulder near Wrek in Wittow, Dr. Haas says "the stork is said to dry the little children, after he has fetched them out of the sea, before he brings them to the mothers. The latter point out these blocks to their little sons and daughters, telling them how once they were laid upon them by the stork to get dry." The great blocks of granite that lie scattered on the coast of Jasmund are termed _Schwansteine_, "swan-stones," and, according to nursery-legend, the children to be born are shut up in them. When a sister or brother asks: "Where did the little _swan-child_"--for so babies are called--"come from?" the mother replies: "From the swan-stone. It was opened with a key, and a little swan-child taken out." The term "swan-child" is general in this region, and Dr. Haas is inclined to think that the swan-myth is older than the stork-myth (466 a. 143, 144). Curious indeed is the belief of the Hidatsa Indians, as reported by Dr. Matthews, in the "Makadistati, or house of infants." This is described as "a cavern near Knife River, which, they supposed, extended far into the earth, but whose entrance was only a span wide. It was resorted to by the childless husband or the barren wife. There are those among them who imagine that in some way or other their children come from the Makadistati; and marks of contusion on an infant, arising from tight swaddling or other causes, are gravely attributed to kicks received from his former comrades when he was ejected from his subterranean home" (433. 516). In Hesse, Germany, there is a children's song (326. I. 9):-- Bimbam, Glöckchen, Da unten steht ein Stöckchen, Da oben steht ein golden Haus, Da gucken viele schöne Kinder raus.
