"Let's go in!" suggested Russ, and he started toward it.
"Maybe you'd better call Grandpa and Daddy, and let them look," said Vi.
Just then Mother Bunker and Grandma Ford, followed by the two smallest children, came into the kitchen.
"Oh, we've found the ghost!" cried Rose to her mother. "It's in the storeroom! Listen!"
The two women listened. The groan sounded very plainly, and did seem to come from the room off the kitchen.
Grandma Ford walked in. All was quiet for a moment, and then the noise sounded again.
"I've found it!" cried Grandma Ford. "I've found the ghost at last!"
"What is it?" exclaimed Mother Bunker.
"I don't know exactly what makes it," said Grandma Ford; "but the noise comes out of this rain-water pipe under the window of the storeroom. We'll call Daddy Bunker and Grandpa Ford and have them look. But come in and listen, all of you."
With their mother the six little Bunkers went into the storeroom. Just as they entered the groan sounded loudly, and, as Grandma Ford said, it came from a rain-water pipe that ran slantingly under the window.
