"We brought a surgeon for him," Frank went on.

"He doesn't need a surgeon now!" replied George. "What he needs more than anything else is a cook!"

"We'll give him two cooks!" shouted Tommy.

"Why don't you hurry up and get us out?" demanded Bert, in a weak voice.

"If you remain in there a few weeks," Tommy laughed, "perhaps you'll get so thin you can crawl out of this crack!"

"Well, get to digging!" replied George.

"And for the love of Mike," exclaimed Sandy, "when you get to digging, don't drop any rocks on top of us! We have a little hole here now about four feet square!"

After making a study of the situation and advising with Doctor Pelton as to the proper course to pursue, the boys began prying at a large rock which lay almost on top of the shelf upon which the boys had ridden to the thicket. The rock moved, but grudgingly.

"If you can move that rock," the doctor said, "I think the one just above it will slide down and leave an opening large enough for the boys to pass out of. It ought not to be much trouble to move it!"

Notwithstanding the doctor's predictions, the boys worked at the rock with their home-made handspikes for an hour before it broke loose and rattled down upon the shelf just above the fire.
