This is the stone over which one is constantly stumbling in this field of scientific research. Mr. Baring-Gould's idea that all household tales are reducible to a primeval root (in the same or a similar manner that we trace words to their roots), though most ingeniously illustrated by him, is constantly involved in trouble of the sort mentioned. He encounters the obstacle which lies in the path of all who walk this way. His roots sometimes get inextricably gnarled and intertwisted with each other.
