stealing. The entrance to the cave is four feet high and four feet wide,
and is in the face of a lofty perpendicular cliff--the sea-wall. You
enter in small boats--and a tight squeeze it is, too. You can not go in
at all when the tide is up. Once within, you find yourself in an arched
cavern about one hundred and sixty feet long, one hundred and twenty

to the bottom of the ocean. The waters of this placid subterranean lake

lustre more superb. Throw a stone into the water, and the myriad of tiny
bubbles that are created flash out a brilliant glare like blue theatrical
fires. Dip an oar, and its blade turns to splendid frosted silver,

armor more gorgeous than ever kingly Crusader wore.

Then we went to Ischia, but I had already been to that island and tired

landed, and so did Dan and the others. It was a remarkable coincidence.
St. Paul preached to these people seven days before he started to Rome.

Nero's Baths, the ruins of Baiae, the Temple of Serapis; Cumae, where the
Cumaen Sybil interpreted the oracles, the Lake Agnano, with its ancient
submerged city still visible far down in its depths--these and a hundred
other points of interest we examined with critical imbecility, but the
Grotto of the Dog claimed our chief attention, because we had heard and
read so much about it. Every body has written about the Grotto del Cane
