We believed that Adwanko's bag of silver was surely in some recess beyond the rock and at once began to lay plans for blasting out the stone with powder.

By using a long fuse, the person that fired the charge would have time to get out before the explosion.
Our party drove there in five double-seated wagons as far as Moose-Yard Brook, where we left the teams and walked the remaining two miles through the woods to Overset Pond.

Besides five of us from the old Squire's, there were our two young neighbors, Thomas and Catherine Edwards, Willis Murch and his older brother, Ben, the two Darnley boys, Newman and Rufus, their sister, Adriana, and ten or twelve other young people.
Besides luncheon baskets and materials to make lemonade, we had taken along axes, two crowbars, two lanterns, four pounds of blasting powder and three feet of safety fuse.

My cousin Addison had also brought a hammer, drill and "spoon." The girls were chiefly interested in the picnic; but we boys were resolved to see what was in the depths of the cave, and immediately on reaching the place several of us lighted the lanterns and went in.
At no place could we stand upright.

Apparently some animal had wintered there, for the interior had a rank odor; but we crawled on over rocks until we came to the obstructing stone sixty or seventy feet from the entrance.
We had planned to drill a hole in the rock, blast it into pieces, and thus clear a passage to what lay beyond it.
