The chasm or gorge between Lover's Leap and the hill west of it is supposed by scientists to have been caused by glacial action.

This is a mistake.
There is an interesting cave a mile or two below Hannibal, among the bluffs.

I would have liked to revisit it, but had not time.

In my time the person who then owned it turned it into a mausoleum for his daughter, aged fourteen.

The body of this poor child was put into a copper cylinder filled with alcohol, and this was suspended in one of the dismal avenues of the cave.
