After Christmas the thermometer dropped to ten below zero.Cold settled on the world.The pasture was bleak and frozen.The cows stayed in the barn all the time now,except on sunny mornings when they went out and stood in the barnyard in the lee of the straw pile.The sheep stayed near the barn, too, for protection.When they were thirsty they ate snow.The geese hung around the barnyard the way boys hang around a drug store,and Mr. Zuckerman fed them corn and turnips to keep them cheerful."Many, many, many thanks!" they always said, when they saw food coming.Templeton moved indoors when winter came.His ratty home under the pig trough was too chilly,so he fixed himself a cozy nest in the barn behind the grain bins.He lined it with bits of dirty newspapers and ragsand whenever he found a trinket or a keepsake he carried it home and stored it there.He continued to visit Wilbur three times a day, exactly at mealtime,and Wilbur kept the promise he had made.Wilbur let the rat eat first.Then, when Templeton couldn't hold another mouthful, Wilbur would eat.As a result of overeating, Templeton grew bigger and fatter than any rat you ever saw.He was gigantic. He was as big as a young woodchuck.The old sheep spoke to him about his size one day."You would live longer," said the old sheep, "if you ate less.""Who wants to live forever?" sneered the rat.
