tation. So we filled two large
tin canteens with water (since we were not acquainted with the locality
of the spring said to exist on the large island), and started. Higbie's
brawny muscles gave the boat good speed, but by the time we reached our
destination we judged that we had pulled nearer fifteen miles than
twelve.

We landed on the big island and went ashore. We tried the water in the
canteens, now, and found that the sun had spoiled it; it was so brackish
that we could not drink it; so we poured it out and began a search for
the spring--for thirst augments fast as soon as it is apparent that one
has no means at hand of quenching it. The island was a long, moderately
high hill of ashes--nothing but gray ashes and pumice-stone, in which we
sunk to our knees at every step--and all around the top was a forbidding
wall of scorched and blasted rocks. When we reached the top and got
within the wall, we found simply a shallow, far-reaching basin, carpeted
with ashes, and here and there a patch of fine sand. In places,
picturesque jets of steam shot up out of crevices, giving evidence that
although this ancient crater had gone out of active business, there was
still some fire left in its furnaces. Close to one of these jets of
steam stood the only tree on the island--a small pine of most graceful
shape and most faultless symmetry; its color was a brilliant green, for
the steam drifted unceasingly through its branches and kept them always
moist. It contrasted strangely enough, did this vigorous and beautiful
outcast, with its dead and dismal surroundings. It was like a cheerful
spirit in a mourning household.

We hunted for the spring everywhere, traversing the full length of the
island (two or three miles), and crossing it twice--climbing ash-hills
patiently, and then sliding down the other side in a sitting posture,
plowing up smothering volumes of gray dust. But we found nothing but
solitude, ashes and a heart-breaking silence. Finally we noticed that
the wind had risen, and we forgot our thirst in a solicitude of greater
importance; for, the lake being quiet, we had not taken pains about
securing the boat. We hurried back to a point overlooking our landing
place, and then--but mere words cannot describe our dismay--the boat was
gone! The chances were that there was not another boat on the entire
lake. The situation was not comfortable--in truth, to speak plainly, it
was frightful. We were prisoners on a
