For some moments the old man did not reply. He stood with bowed head, buried in deep thought. But at last he spoke.

## AA

I have no idea, of course, how long it took me to reach the limit of the plain,
but at last I entered the foothills, following a pretty little canyon upward
toward the mountains. Beside me frolicked a laughing brooklet, hurrying upon
its noisy way down to the silent sea. In its quieter pools I discovered many
small fish, of four-or five-pound weight I should imagine. In appearance,
except as to size and color, they were not unlike the whale of our own seas. As
I watched them playing about I discovered, not only that they suckled their
young, but that at intervals they rose to the surface to breathe as well as to
feed upon certain grasses and a strange, scarlet lichen which grew upon the
rocks just above the water line.

### AAA

I remember I felt an extraordinary persuasion that I was being played with,
that presently, when I was upon the very verge of safety, this mysterious
death--as swift as the passage of light--would leap after me from the pit about
the cylinder and strike me down. ## BB

### BBB

"You're a great Granser," he cried delightedly, "always making believe them little marks mean something."
