Ne-naw-bo-zhoo The Teacher
This story was related by Andrew J. Blackbird or Mack-aw-de-be-nessy (Black Hawk) of the Odawa Nation, in his 1897 book Indians of Michigan: The Ottawa and Chippewa.
From Chapter IX
Some of the legends of the Ottawa and Chippewa Indians Respecting the Great Flood of the World -- A Person Swallowed Up Alive Like a Prophet Jonah.
They have a tradition of a great flood, as is recorded in the Bible History, and many other tribes of Indians who speak dialect of the Ottawa and Chippewa languages have the same story. The legends say it was caused, not by a rain, but by the great "Ne-naw-bo-zhoo", who was the most remarkable, wonderful, and supernatural being that ever trod upon the earth. He could transfigure himself into the shape of all animals and live with them for a great length of time. He has done much mischief and also many benefits to the inhabitants of the earth whom he called "his nephews" and he shaped almost everything, teaching his nephews what materials they should take for their future utensils. This mischievous Ne-naw-bo-zhoo spoiled the sugar trees by diluting their sap with water. The legends say that once upon a time the sugar trees did produce sap at certain season of the year which was almost like a pure syrup; but when this mischievous Ne-naw-bo-zhoo had tasted it, he said to himself, "Ah, that is too cheap. It will not do. My nephews will obtain this sugar too easily in the future time and the sugar will be worthless." And therefore he diluted the sap until he could not taste any sweetness therein. Then he said "Now my nephews will have to labor hard to make the sugar out of this sap, and the sugar will be much more valuable to them in the future time." In former times the heart of every tree contained fat from which all inhabitants of the earth obtained delicious oil to eat; but this mischievous Ne-naw-bo-zhoo, in his supernatural way, pushed his staff into the heart of every tree; and this is the reason why the heart of every tree has a different color.
