reasure, as you must know. I am going after that
and leave you where you are."

"Bound to these trees?"

"Certainly."

"Supposing we can't get loose?" remonstrated Tom. "We may starve to
death!"

"That will be your lookout. But I reckon you'll get loose sooner or
later, although we've bound you pretty tight."

"Can I have a drink before you go?" asked Sam, who was dry.

"Don't give 'em a drop, Uncle Sid!" cried Tad. "They don't deserve
it."

"Oh, they can have a drink," said Sid Merrick. "I'd give a drink even
to a dog," he added, and passed around some water the boys had in a
bottle.

Less than fifteen minutes later the three Rover boys found themselves
alone in the forest. The Merrick party had lit their acetylene gas
lamp and the lantern and struck out once more along the trail which
they supposed would take them to the treasure cave. The boys heard
them for a short distance, and then all became dark and silent around
them.

"Well, now we are in a pickle and no mistake," remarked Sam, with a
long sigh.

"That ghost business proved a boomerang," was Tom's comment. "It's a
pity we didn't dig out for the shore, signal to the steam yacht, and
tell father and the others about what was going on."

"There is no use crying over spilt milk," said Dick. "The first thing
to do is to get free."

"Yes, and that's real easy," sniffed Tom. "I am bound up like a bale
of hay to be shipped to the South Pole!"

"And the cord on my wrists is cutting right into the flesh," said Sam.

"If we were the heroes of a dime novel we'd shoo these ropes away in a
jiffy," went on Tom, with a grin his brothers could not see. "But
being plain, everyday American boys I'm afraid we'll have to stay tied
up until somebody comes to cut us loose."

"Oh, for a faithful dog!" sighed Sam. "I saw a moving picture once in
which a dog came and untied a girl who was fastened to a tree. I'd
give as much as five dollars for that dog right now."

"Make it six and a half, Sam, and I'll go half," answered Tom.

"Well, this is no joke," declared Dick, almost severely. "We must get
free somehow--or they'll get that treasure and be off with it before
father and the others have a chance to land. We've got to do
something."

They all agreed they "had to do something," but what that something was
to be was not clear. They worked over their bonds until their wrists
were cut and bleeding and then gave the task up. It was so dark they
could see each o
