cement

The setting sun shone full upon the passage floor, and I could see that the old, foot-worn grey stones with which it was paved were firmly cemented together, and had certainly not been moved for many a long year.

After several blows he perceived that the stones were not cemented, but had been merely placed one upon the other, and covered with stucco; he inserted the point of his pickaxe, and using the handle as a lever, with joy soon saw the stone turn as if on hinges, and fall at his feet.

The sea, knowing what was required of her, threw over them her weeds, encircled them with coral, and encrusted them with shells; the whole was cemented by two hundred years beneath these almost impervious depths, for a revolution carried away the emperor who wished to make the trial, and only left the documents proving the manufacture of the jars and their descent into the sea.

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.
