in behind the cascade and the pyramid, and found the bluff
pierced by several cavernous tunnels, whose crooked courses we followed a
long distance.

Two of these winding tunnels stand as proof of Nature's mining abilities.
Their floors are level, they are seven feet wide, and their roofs are
gently arched. Their height is not uniform, however. We passed through
one a hundred feet long, which leads through a spur of the hill and opens
out well up in the sheer wall of a precipice whose foot rests in the
waves of the sea. It is a commodious tunnel, except that there are
occasional places in it where one must stoop to pass under. The roof is
lava, of course, and is thickly studded with little lava-pointed icicles
an inch long, which hardened as they dripped. They project as closely
together as the iron teeth of a corn-sheller, and if one will stand up
straight and walk any distance there, he can get his hair combed free of
charge.

CHAPTER LXXIV.

We got back to the schooner in good time, and then sailed down to Kau,
where we disembarked and took final leave of the vessel. Next day we
bought horses and bent our way over the summer-clad mountain-terraces,
toward the great volcano of Kilauea (Ke-low-way-ah). We made nearly a
two days' journey of it, but that was on account of laziness. Toward
sunset on the second day, we reached an elevation of some four thousand
feet above sea level, and as we picked our careful way through billowy
wastes of lava long generations ago stricken dead and cold in the climax
of its tossing fury, we began to come upon signs of the near presence of
the volcano--signs in the nature of ragged fissures that discharged jets
of sulphurous vapor into the air, hot from the molten ocean down in the
bowels of the mountain.

Shortly the crater came into view. I have seen Vesuvius since, but it
was a mere toy, a child's volcano, a soup-kettle, compared to this.
Mount Vesuvius is a shapely cone thirty-six hundred feet high; its crater
an inverted cone only three hundred feet deep, and not more than a
thousand feet in diameter, if as much as that; its fires meagre, modest,
and docile.--But here was a vast, perpendicular, walled cellar, nine
hundred feet deep in some places, thirteen hundred in others,
level-floored, and ten miles in circumference! Here was a yawning pit
upon whose floor the armies of Russia could camp, and have room to spare.

Perched upon the edge of the crater, at the opp
