I could hear somewhere near the sound of running water, but I could not locate it.

Now and again at irregular intervals there was a prolonged booming, which could only come from a wave breaking in a confined place.

The recollection then came to me of the proximity of the church to the top of the beetling cliff, and of the half-sunk cavern entrances which pierced it.
With the gleam of my lamp to guide me, I went through and round the whole place.

There were many massive tombs, mostly rough-hewn from great slabs or blocks of stone.

Some of them were marble, and the cutting of all was ancient.
