"And this is my friend, Tot Thompson," she continued.
"I'm Tot Tompum," said Tot gravely.
"Oh," replied the man. "I'm pleased to make your acquaintance. I'm the Watch-Dog of Merryland."
"What a queer name!" exclaimed Dot. "Why do they call you that?"
"Because I'm placed here to keep everyone from passing through the archway that spans the river into the fair and happy valleys of Merryland."
"How can you keep them from passing through?" asked the girl.
"Why, tell them they mustn't, of course."
"But suppose they won't mind you, what will you do then?"
The old man looked puzzled, and shook his head slowly.
