The shadowy figures had disappeared as though by magic, seeking shelter behind the trees that fringed the clearing.

Bomba could hear the sound of axes. His enemies were cutting down a tree. For what purpose?

The question was quickly answered. A dozen savages emerged from the shadows, bearing between them a heavy log ten feet long, with the evident purpose of using it as a battering ram to beat in the door.

Bomba knew that if they succeeded in this, Casson and he were lost. Once let that horde invade the cabin, and nothing could avail against overpowering numbers.

No time for arrows now. He had a far quicker weapon at hand. The white man’s fire stick!

They were so near that he could not miss. So swiftly that the repeated detonations blended into one continuous report, he emptied the five chambers of the revolver.

At that close range every shot took its toll in dead and wounded. Several fell, others staggered back to the shelter of the woods. Among the wounded Bomba recognized the towering figure of Nascanora. The log went down with a crash, and the survivors of those who had been carrying it fled in panic.

It was not only the execution done, but the way it had been done that filled them with fright. Few of them had ever before heard the report of a firearm—perhaps none of them. The spurts of flame and the roar of the weapon confirmed their conviction that the hut was the habitation of wizards.

A snake that walked on two feet! Fire that spoke and killed! What chance had they with their bows and arrows, especially when they could not see their targets?

Bomba handed the revolver to Casson to reload, and in the meantime fitted another arrow to his bow. But though he strained his eyes through the darkness, he could find nothing at which to shoot.
