can be imagined. They are as
transparent as plate glass, and their coloring would shame the richest
sky that ever bent over Italy. No tint could be more ravishing, no
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,
tinted with blue. Let a man jump in, and instantly he is cased in an
armor more gorgeous than ever kingly Crusader wore.

Then we went to Ischia, but I had already been to that island and tired
myself to death "resting" a couple of days and studying human villainy,
with the landlord of the Grande Sentinelle for a model. So we went to
Procida, and from thence to Pozzuoli, where St. Paul landed after he
sailed from Samos. I landed at precisely the same spot where St. Paul
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
and its poisonous vapors, from Pliny down to Smith, and every tourist has
held a dog over its floor by the legs to test the capabilities of the
place. The dog dies in a minute and a half--a chicken instantly. As a
general thing, strangers who crawl in there to sleep do not get up until
they are called. And then they don't either. The stranger that ventures
to sleep there takes a permanent contract. I longed to see this grotto.
I resolved to take a dog and hold him myself; suffocate him a little, and
time him; suffocate him some more and then finish him. We reached the
grotto at about three in the afternoon, and proceeded at once to make the
experiments. But now, an important difficulty presented itself. We had
no dog.

ASCENT OF VESUVIUS--CONTINUED.

At the Hermitage we were about fifteen or eighteen hundred feet above the
sea, and thus far a portion of the ascent had been pretty abrupt. For
the next two miles the road was a mixture--sometimes the ascent was
abrupt and s
