tant era Caprona was a mighty mountain--perhaps the world's
mightiest volcanic action blew off the entire crest, blew thousands of
feet of the mountain upward and outward and onto the surrounding
continent, leaving a great crater; and then, possibly, the continent
sank as ancient continents have been known to do, leaving only the
summit of Caprona above the sea. The encircling walls, the central
lake, the hot springs which feed the lake, all point to a conclusion,
and the fauna and the flora bear indisputable evidence that Caprona was
once part of some great land-mass.

As we cruised up along the coast, the landscape continued a more or
less open forest, with here and there a small plain where we saw
animals grazing. With my glass I could make out a species of large red
deer, some antelope and what appeared to be a species of horse; and
once I saw the shaggy form of what might have been a monstrous bison.
Here was game a plenty! There seemed little danger of starving upon
Caprona. The game, however, seemed wary; for the instant the animals
discovered us, they threw up their heads and tails and went cavorting
off, those farther inland following the example of the others until all
were lost in the mazes of the distant forest. Only the great, shaggy
ox stood his ground. With lowered head he watched us until we had
passed, and then continued feeding.

About twenty miles up the coast from the mouth of the river we
encountered low cliffs of sandstone, broken and tortured evidence of
the great upheaval which had torn Caprona asunder in the past,
intermingling upon a common level the rock formations of widely
separated eras, fusing some and leaving others untouched.

We ran along beside them for a matter of ten miles, arriving off a
broad cleft which led into what appeared to be another lake. As we were
in search of pure water, we did not wish to overlook any portion of the
coast, and so after sounding and finding that we had ample depth, I ran
the U-33 between head-lands into as pretty a landlocked harbor as
sailormen could care to see, with good water right up to within a few
yards of the shore. As we cruised slowly along, two of the boches
again saw what they believed to be a man, or manlike creature, watching
us from a fringe of trees a hundred yards inland, and shortly after we
discovered the mouth of a small stream emptying into the bay: It was
the first stream we had found since leaving the river, and I at once
