Witches, wit, and a werewolf Book

This book is assigned 398 by LOC as traditional literature. It would be considered a pourquoi - a story that explains the origins of natural traits. There is little to no attribution of sources: the end flap merely states that the author's "acquaintance with the many tales of Why the Tides Ebb and Flow . . . stirred her to tell this one." Printed on tan paper, with a border of brown and black, the line drawings evoke images from long ago. This is the story of a woman who asks the Sky Spirit for a rock to shelter her from the weather. Not thinking, the Sky Spirit tells her to take one. The one she takes is the rock from the hole in the bottom of the sea. The Sky Spirit sends a dog, a girl and and a young man to try to fill the hole, but ultimately must allow the old woman to take it twice a day to put in her garden. Hence, the tides.
