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.
