The eyes were set in the swaying head of a cooanaradi, the most terrible serpent on earth.

It lay in its lair just beside the path that Bomba was following, its body, fourteen feet in length, thrown into coils, above which the slender head swayed back and forth. Evilly beautiful, it glowed with all the colors of the rainbow.

Had it been a rattlesnake or any other poisonous denizen of the jungle, it would have glided away into the bushes, glad enough to avoid an encounter with human enemies unless attacked. Even the boa or the anaconda is apathetic and, except when moved by hunger, seldom takes the initiative.

But what makes the cooanaradi so dreaded, apart from its deadly poison, is its ferocity. It does not avoid attack; it seeks to make it. Nor is it satisfied when its enemy flees; it follows in pursuit.

But there was no need yet for that. All unsuspecting, its prey was coming toward it. Soon he would be in reach of the lightning stroke. The evil eyes gloated in anticipation.

Then, when Bomba was barely ten feet away, he saw it!

There was no time to string his arrow. There was no time to draw his machete. Even while he looked, the snake launched its spring.

Like a flash Bomba turned and ran for his life!

CHAPTER II
THE MEN WITH THE IRON STICK

At the moment that Bomba made his first startled leap he heard close behind him the thud of a body as it struck the earth. The reptile had missed its spring.
