It was known that one of them owed the other money; they had been quarreling about it as they entered the tunnel from the cellar of Morris's.

It was conjectured that the quarrel had progressed and that the debtor had endeavored, by the light of his pocket lantern in the tunnel, to palm off a counterfeit bill in settlement of the debt.

This may have led to a blow, or more likely only to an argument during which a bomb was dropped and exploded, followed quickly by the other explosion.

Dead hand, counterfeit bill and ring were flung whimsically to the surface of the earth together, and the leaning rocks had been astonishingly broken from beneath through this trivial quarrel.

Had it not been for this squabble the Jasper B.and all on board must have been destroyed.
