"I believe I'll investigate this," said Snap, arising and reaching
for a shotgun. "I don't believe in ghosts, so there!"

"I'll go along," put in the doctor's son.

"Please don't leave me alone!" pleaded Whopper. "I can't go and
I don't want to be left behind."

"Giant, will you stay with Whopper?" asked the leader of the club.

"Yes, but I hope you won't be gone long," answered the small youth,
in a voice he tried in vain to steady.

"If anything happens, whistle or fire a shot," added Snap, and
walked slowly to the rear of the camping place, with Shep by his side.

The two young investigators soon found themselves beside the spring,
and here both stopped for a drink, for their throats seemed to be
suddenly, parched. They looked on all sides with extreme care, but
saw nothing out of the ordinary. Once a bird flew up directly in
front of them, causing them to jump and raise their guns. But they
were not after game just then, so the bird got away.

"We certainly heard that voice, just as plain as day," said Shep.
"What do you make of this, Snap?"

"I am sure I don't know."

"Can somebody be fooling us?"
