As the refreshing rain which accompanies the thunder gust instills new life into vegetation, and covers the ground parched by summer droughts with leaves and grass, so the statement in the myth that the fragments of the flint-stone grew into fruitful vines is an obvious figure of speech which at first expressed the fertilizing effects of the summer showers.
In this myth Michabo, the Light-God, was represented to the native mind as still fighting with the powers of Darkness, not now the darkness of night, but that of the heavy and gloomy clouds which roll up the sky and blind the eye of day.

His weapons are the lightning and the thunderbolt, and the victory he achieves is turned to the good of the world he has created.
This is still more clearly set forth in an Ojibway myth.

It relates that in early days there was a mighty serpent, king of all serpents, whose home was in the Great Lakes.

Increasing the waters by his magic powers, he began to flood the land, and threatened its total submergence.

Then Michabo rose from his couch at the sun-rising, attacked the huge reptile and slew it by a cast of his dart.
