"He is beyond all help," I faltered.

"But he can be avenged," said Edmund, in a tone that I had never heard him use before.

As he spoke he whipped out his pistol, and crash! crash! crash! sounded the hurrying shots. As their echo ceased, the giant arachnid dropped his prey, and then there came from him—clear, piercing, quivering through our nerves—that arrowy whistle that had caused us to shudder as we unwillingly listened to it darting out of the gloom of the impenetrable thickets.

Then, to our horror, the creature, which, if touched at all by the shots, had not been seriously injured, picked up its prey and bounded away in the darkness. Edmund instantly turned to Ala, and I knew as well as if he had spoken, what his demand was. He wished to follow, and his wish was obeyed. We swooped ahead, and in a minute we saw the creature again. It had stopped on another oasis of dry land, and it still carried its dreadful burden. Its head was toward us, and it appeared to be watching our movements. Its battery of eyes glittered wickedly, and I noticed the bristle of stiff hairs, like wires, that covered its body and legs.

Again Edmund fired upon it, and again it uttered its stridulous pipe of defiance, or fear, and leaped away in the tangle. We sped in pursuit, and when we came upon it for the third time it had stopped in an opening so narrow that the bow of the air ship almost touched it before we were aware of its presence. This time its prey was no longer visible. There was no question now that its attitude meant defiance. Cold shivers ran all over me as, with fascinated eyes, I gazed at its dreadful form. It seemed to be gathering itself for a spring, and I shrank away in terror.

Crash! bang! bang! bang! sounded the shots once more, and in the midst of them there came a blinding tangle of bristled, jointed legs that thrashed the deck, a thud that shook the air ship to its center, and a cry from Jack, who fell on his back with a crimson line across his face.

"Give me your pistol!" shouted Edmund, snatching my arm.

I hardly know how I got it out of my pocket, I was so unnerved, but it was no sooner in Edmund's hand than he was leaning over the side of the deck and pouring out the shots. When the pistol was emptied he straightened up, and said simply:

"That devil is ended."

Then he turned to where Jack lay on the deck. We all bent over him with anxious hearts, even Ala sharing our solicitude. He had lost his senses, but a drop from Edmund's flask immediately brought him round, and he rose to his feet.
