moved along, I noticed that the floor was composed of solid rock, in
places covered with a damp mould, in others bare, or almost so, save for
a thin coating of light-grey dust.

I had halted at the doorway. Now, however, I turned, and made my way up
the center of the place; passing among the pillars, and glancing to
right and left, as I moved. About halfway up the cellar, I stubbed my
foot against something that gave out a metallic sound. Stooping quickly,
I held the candle, and saw that the object I had kicked, was a large,

backward, letting the trap fall, with a hollow clang, that filled the
place with echoes. Even then, I seemed to hear that mocking, suggestive
