"But where are we? What happened? My head is dizzy—I don't know—"

I gripped his hand.

"And no wonder. 'Tis hardly an every-day occurrence to ride an underground river several miles under the Andes. Above us a mountain four miles high, beneath us a bottomless lake, round us darkness. Not a very cheerful prospect, Hal; but, thank Heaven, we take it together! It is a grave—ours and hers. I guess Desiree knew what she was talking about."

There came a cry from Harry's lips—a cry of painful memory:

"Desiree! I had forgotten, Desiree!"

"She is probably better off than we are," I assured him.

I felt his gaze—I could not see it—and I continued:

"We may as well meet the thing squarely like men. Pull yourself together, Harry; as for Desiree, let us hope that she is dead. It's the best thing that could happen to her."

"Then we are—no, it isn't possible."

"Harry boy, we're buried alive! There! That's the worst of it. Anything better than that is velvet."
