ooker is working over to the other end of the cemetery--cutting
down an old tree. You might get him."

"Where?"

"I'll show you."

Jennie ran to get her hat. She was just putting it on when a bell began
to ring in the hall of the cottage.

"Gracious me!" gasped the girl.

"What's the matter now?"

"That's the bell to the new vault."

"I don't understand."

"There is an electric button in the vault. When you push it, it unlocks
the door and rings this bell. It was put there in case somebody was in
the vault in a trance and came to life again."

"What!" ejaculated Sam. "Then that rascal must have pushed the button
and opened the door from the inside."

"Yes."

"I'm off. He is not going to escape if I can help it." And so speaking,
the youngest Rover dashed off the porch of the cottage and in the
direction from whence he had come.

It did not take him long to reach the new vault and a glance through
the open doorway showed him that his bird had flown.

"What a dunce I was not to think of that electric button!" he mused.

should not get away so easily again.

The end of the cemetery bordered on the Swift River, a stream which has
already figured in these stories of the Rover boys. It was a rocky,
swift-flowing watercourse, and the bank at the end of the burying
ground was fully ten feet high.

"Perhaps he crossed the river," thought the youngest Rover. "But he
couldn't do that very well unless he had a boat and then he would run
the risk of being dashed on the rocks."

The edge of the river reached, Sam looked around on all sides of him.
Lew Flapp was still nowhere to be seen.

"I've missed him," thought Sam. "What next?"

As the youngest Rover stood meditating, a figure stole from behind some
bushes which were close at hand. The figure was that of Lew Flapp, who
had been on the point of turning back when he had seen Sam coming.

"He will raise an alarm as soon as he sees me," reasoned the bully.
"Oh, if only I could get him out of my way!"

He gazed at the youngest
