Titanic

Whole days have I passed in these Titanic efforts, considering my labor well repaid if, by night-time I had contrived to carry away a square inch of this hard-bound cement, changed by ages into a substance unyielding as the stones themselves; then to conceal the mass of earth and rubbish I dug up, I was compelled to break through a staircase, and throw the fruits of my labor into the hollow part of it; but the well is now so completely choked up, that I scarcely think it would be possible to add another handful of dust without leading to discovery.
