"Once in a while it happens that food becomes very scarce where the Lemmings are. Then very many of them get together, just as migrating birds form great flocks, and start on a long journey in search of a place where there is plenty of food. They form a great army and push ahead, regardless of everything. They swim wide rivers and even lakes which may lie in their way. Of course, they eat everything eatable in their path."

"My!" exclaimed Danny Meadow Mouse, "I'm glad I don't live in a country where I might have to make such long journeys. I don't envy those cousins up there in the Far North a bit. I'm perfectly satisfied to live right on the Green Meadows."

"Which shows your good common sense," said Old Mother Nature. "By the way, Danny, I suppose you are acquainted with Nimbleheels the Jumping Mouse, who also is rather fond of the Green Meadows. I ought to have sent word to him to be here this morning."

Hardly were the words out of Old Mother Nature's mouth when something landed in the leaves almost at her feet and right in the middle of school. Instantly Danny Meadow Mouse scurried under a pile of dead leaves. Whitefoot the Wood Mouse darted into a knothole in the log on which he had been sitting. Jumper the Hare dodged behind a little hemlock tree. Peter Rabbit bolted for a hollow log. Striped Chipmunk vanished in a hole under an old stump. Johnny Chuck backed up against the trunk of a tree and made ready to fight. Only Happy Jack the Gray Squirrel and Chatterer the Red Squirrel and Prickly Porky the Porcupine, who were sitting in trees, kept their places. You see they felt quite safe.
