It was because our attention was thus focused that we did not notice the approach of several canoes loaded with warriors, coming downstream toward us from the foothills, until one of my men discovered them and gave the alarm when they were only a matter of a couple of hundred yards from us.

I hoped that they would prove friendly, as I had no desire to kill them, for, primitively armed as they were, they would be helpless in the face of our rifles; and so I gave the sign of peace, hoping to see it acknowledged in kind upon their part; but they made no response.

Closer and closer they came, until I could see them quite plainly. They were heavy-built, stocky warriors with bushy beards, a rather uncommon sight in Pellucidar where most of the pure-blood white tribes are beardless.

When they were about a hundred feet from us, their canoes all abreast, a number of warriors rose in the bow of each boat and opened fire upon us.

I say, "opened fire," from force of habit. As a matter of fact what they did was to project dart-like missiles at us from heavy sling-shots. Some of my men went down, and immediately I gave the order to fire.

I could see by their manner how astonished the bearded warriors were at the sound and effect of the rifles; but I will say for them that they were mighty courageous, for though the sound and the smoke must have been terrifying they never hesitated, but came on toward us even more rapidly. Then they did something that I had never seen done before nor since in the inner world. They lighted torches, made of what I afterward learned to be a resinous reed, and hurled them among us.

These torches gave off volumes of acrid black smoke that blinded and choked us. By the effects that the smoke had upon me, I know what it must have had upon my men; but I can only speak for myself, because, blinded and choking, I was helpless. I could not see the enemy, and so I could not fire at them in self-defense. I wanted to jump into the river and escape the smoke; but I knew that if I did that I should be immediately devoured by the ferocious creatures lurking beneath the surface.
