together, there grew out knots, and, although the trees sufiered, they lived. All the rest were ruined; below the rings there came out shoots, but they were all wild.
The bark of the tree is hke the arteries in man: through the arteries the blood goes to the whole body, and through the bark the sap goes along the tree and reaches the branches, leaves, and flowers. The whole inside of a tree may be taken out, as is often the case with old willows, and yet the tree will live so long as the bark is alive; but when the bark is ruined, the tree is gone. If a man's arteries are cut through, he will die, in the first place, because the blood will flow out, and in the second, because the blood will not be distributed through the body.
Even thus a birch dries up when the children bore a hole into it, in order to drink its sap, and all the sap flows out of it.
Just so the apple-trees were ruined because the mice gnawed the bark all around, and the sap could not rise from the roots to the branches, leaves, and flowers.
