The children were not expecting it, and they almost jumped out of their skins with fright. Then they clutched at one another, expecting the men to come chasing along at once, having heard Daisy.

There was an astonished silence. Then one of the men said, “Did you hear that?”

“Of course!” said another. “What in the wide world was it?”

“Well, it wasn’t the children, that’s certain!” said the first, with a laugh. “I never in my life heard a child make a noise like that!”

“It sounded like a cow,” said another voice.

“A cow!” cried the first man, “what next? Do you mean to say you think there’s a cow in the middle of this hill, Tom?”

“Of course there can’t be,” said Tom, laughing. “But it sounded mighty like one! Let’s listen and see if we hear anything again.”

There was a silence, as if the men were listening - and at that moment Daisy most obligingly gave a dreadful hollow cough, that echoed mournfully round and round the cave.

“I don’t like it,” said a man’s voice. “It sounds too queer for anything. Let’s get out of these dark caves into the sunshine. I’m perfectly certain, since we heard those noises, that no children would be inside those caves! Why, they’d be frightened out of their lives!”

Jack squeezed Nora’s hand in delight. So old Daisy had frightened the men! What a glorious joke! The children sat as still as could be, glad now that Daisy had given such a loud moo and such a dreadful cough.
