From the painting by Rousseau in the Metropolitan Museum of Art.
THE EDGE OF THE WOODS
Last of all come tramping along the sturdy old oaks.
Last of all come tramping along the sturdy old oaks and the nut-bearing trees. Their seeds are so heavy they get little help from the winds, and then only in the most violent storms. They must advance very slowly indeed, with occasional help from absent-minded squirrels who carry away and bury nuts and acorns and then forget where they put them.
HOW SQUIRRELS HELP OAKS TO MARCH
Sometimes they bury acorns and forget just where. When frightened they often drop them and run away.
