ge of the
chasm, in places almost completely shutting out the light of day.
This was not like the other chasm. It was deeper and darker and more
sullen. Under its walls the gloom was almost that of night. Its
solitude was voiceless; not a bird fluttered or chirped among
its rocks; the lowest of whispered words sounded with startling
distinctness. Once Rod spoke aloud, and his voice rose and beat itself
in the cavernous depths of the walls until it seemed as though he had
shouted. Now they ceased paddling, and Mukoki steered. Noiselessly the
current swept them on. In the twilight gloom Rod's face shone
with singular whiteness. Mukoki and Wabigoon crouched like bronze
silhouettes. It was as if some mysterious influence held them in its
power, forbidding speech, holding their eyes in staring expectancy
straight ahead, filling them with indefinable sensations that made
their hearts beat faster and their blood tingle.
Softly, from far ahead, at last there came a murmur. It was like the
first gentle whispering of an approaching wind, the soughing of a

his companions, and though he spoke no word there was the gleam of a
great excitement in his eyes. Rod's heart beat like a drum. He, too,
began to understand. That moaning, whispering sound floating up
the chasm was not the wind, but the far-away rumble of the third
waterfall!
Mukoki's voice broke the tense silence from behind.
"That the fall!"
Wabigoon replied in words scarcely louder than a whisper. There was no
joyful shouting now, as there had been at the discovery of the second
fall. Even Mukoki's voice was so low that the others could barely
hear. Something between these chasm walls seemed to demand silence
from them, and as the rumble of the cataract came more and
more clearly to their ears they held their breath in voiceless
anticipation. A few hundred yards ahead of them was the treasure which
men long since dead had dis
