"Oh, I hardly think so," said Mrs. Dalton, though she was afraid this might have happened. "I guess Ruddy just ran off to play with Peter, or some other dog."

"But he never did it before!" exclaimed Rick. "He always knows when I'm coming from school and he waits for me."

This was true enough, and Mrs. Dalton knew it. Just then Mazie, who had stopped on her way home from school to talk to some of her girl friends, came into the yard.

"Did you see Ruddy?" asked Rick, eagerly.

"No," was the answer. "Oh, is he lost, Rick?"

"I—I'm afraid so," was the reply. "I'm going to go out and look for him."

"Better look over in Peter's yard," suggested Mrs. Dalton. "Ruddy may be there."

But the red-brown setter dog was not playing with the queer sleepy-eyed, though good-natured English bull. Peter was gnawing a bone near his kennel when Rick hurried in.

"Bow wow!" barked Peter, for that was his way of saying "Hello!"

"Here, Ruddy! Ruddy!" called Rick, looking around the yard of Tom Martin's house, for Rick thought his dog might have been playing with Peter a game very much like the boys' game of hide-and-go-seek.
