CHAPTER II
THE POSTMAN'S WHISTLE
"Oh, Trouble has fallen! Trouble has fallen!" screamed Jan, as she ran around toward the back of the toboggan.
"Come on, Tom!" yelled Ted. "I guess my little brother's hurt!"
Lola followed the others, and as the four children raced to the aid of baby William a shrill whistle was heard near the front of the house.
"Is that a policeman?" cried Tom to his chum.
"No, it's the postman," answered Ted. "He's taking a letter into our house. Hey, Mr. Brennan!" he called, as he saw the gray-uniformed mail carrier entering the yard. "My little brother's hurt!"
Screams coming from the mouth of William seemed to tell that he was badly frightened, anyhow, and also hurt, very likely.
"Trouble hurt? I'm coming!" cried the postman dropping his bag of mail and running around the side path.
Another moment and the Curlytops and their playmates had reached the rear of the high pile of boxes from which the toboggan slide started. They looked on the ground, expecting to see Trouble huddled there in a crumpled heap.
