"The beams are put in in the rough, and if we hunt carefully, I think we shall find a plank where we can get the irons in far enough, between it and the beam, to give us a hold." After a careful examination, they fixed upon a plank to operate upon, and, leaving one of the irons there, so that they could find it in the dark, they lay down to sleep, or sat talking until it was dark.

Before this, a glance, through the peephole, showed them that the hatch had been placed over the hatchway of the next hold, so that there was little fear of anyone coming down, unless something special was required.
"Now I think we can begin," Francis said, at last.
