CHAPTER XXII

THE CAVE OF THE BANDITS

The top of the tree sprang up with such force, when relieved of the weight of the fat boy, that Tad Butler lost his hold and was catapulted to the ground, which he struck with a force that made his bones ache.

The two Pony Rider Boys sat up rubbing themselves and looking into each others’ faces.

“Well, what do you think of that?” jeered Stacy Brown.

“I think we got a fine tumble,” replied Tad, grinning.

“And I think something else, too.”

“Yes, we’ve made a discovery!”

“A great discovery,” breathed Stacy tensely.

“I think so, but that remains to be seen.  Who would have thought it?  But get away from here!  We may have disturbed some one.”

The lads quickly scrambled up and, skulking into the bushes, crouched down, watching the roots of the tree, almost expecting them to rise into the air again.  Nothing of the sort happened.  The birds were singing in the trees, the sun was shining brightly, the heat was intense.

“I’m going to investigate,” declared Tad.

“Maybe we’ve discovered another gold mine, or perhaps a German dugout,” suggested Chunky.

“Perhaps, but not in the way you think.”

“How do you mean?”

“Wait until we investigate.  There may be more to this than either of us think.  I wonder if we can weight that tree down so the roots will stay up in the air?”

“I saw some rocks there near the top.  Perhaps we can make them stay on so the top will be held down.”

“You get up on the tree again and I’ll pass the rocks up to you.  Place them so they won’t slide off.  I don’t want to get crushed by them falling on me.”

“Neither do I want to get thrown off again.  I’m black and blue all over, right this minute.”

“I think I must be by the feel of my skin.  Hurry!”

Stacy ran back to the roots, once more clambering to the trunk, along which he ran clear to the outer end.  Tad was ready with a heavy, flat rock which he carefully raised by main strength.

“Now, don’t you dare let that drop on me or I’ll be mashed flat, Stacy Brown.”

“I—–­I won’t let it d-d-rop un—–­unless I—–­I fall off.”

The rock nearly got away from the fat boy.  Butler leaped back out of the way, but Stacy recovered himself in time and after some effort succeeded in placing the rock in the limbs of the tree.

“Fits as if it had been here before,” declared Chunky.

“Perhaps it has.  We shall see.  Are you ready?”

“Yep.”

“Here’s another.”

By the time the third stone had been put in place the top of the tree began to settle.  The fourth rock brought the tree down to the ground, exposing the opening in the rocks once more.

“Hurrah!”

“Keep still.  Don’t move till I get enough up there to equalize your weight.  Then you may come down.”
