They should not have left it in a gouged, open hollow under a boulder near the dugout.

They were not burdened by the weight of their brains, I imagine.
Just here I should like to say a few words to those who are wholly ignorant of the devastating power contained in "giant powder"-- which is dynamite.

If you have never had any experience with the stuff, you are likely to go out with a bang and a puff of bluish-brown smoke when you go.

On the other hand, you may believe the weird tales one reads now and then, of how whole mountainsides have been thrown down by the discharge of a few sticks of dynamite.

Or of one man striking terror to the very souls of a group of mutinous miners by threatening to throw a piece at them.
