To run seemed ridiculous, especially toward that steep and unscalable cliff, and yet I did so, and as I ran I saw Ja, agile as a monkey, crawl down the precipitous face of the rocks, clinging to small projections, and the tough creepers that had found root-hold here and there.

The labyrinthodon evidently thought that Ja was coming to double his portion of human flesh, so he was in no haste to pursue me to the cliff and frighten away this other tidbit.  Instead he merely trotted along behind me.

As I approached the foot of the cliff I saw what Ja intended doing, but I doubted if the thing would prove successful.  He had come down to within twenty feet of the bottom, and there, clinging with one hand to a small ledge, and with his feet resting, precariously upon tiny bushes that grew from the solid face of the rock, he lowered the point of his long spear until it hung some six feet above the ground.

To clamber up that slim shaft without dragging Ja down and precipitating both to the same doom from which the copper-colored one was attempting to save me seemed utterly impossible, and as I came near the spear I told Ja so, and that I could not risk him to try to save myself.

But he insisted that he knew what he was doing and was in no danger himself.

“The danger is still yours,” he called, “for unless you move much more rapidly than you are now, the sithic will be upon you and drag you back before ever you are halfway up the spear—­he can rear up and reach you with ease anywhere below where I stand.”

Well, Ja should know his own business, I thought, and so I grasped the spear and clambered up toward the red man as rapidly as I could—­being so far removed from my simian ancestors as I am.  I imagine the slow-witted sithic, as Ja called him, suddenly realized our intentions and that he was quite likely to lose all his meal instead of having it doubled as he had hoped.

When he saw me clambering up that spear he let out a hiss that fairly shook the ground, and came charging after me at a terrific rate.  I had reached the top of the spear by this time, or almost; another six inches would give me a hold on Ja’s hand, when I felt a sudden wrench from below and glancing fearfully downward saw the mighty jaws of the monster close on the sharp point of the weapon.

I made a frantic effort to reach Ja’s hand, the sithic gave a tremendous tug that came near to jerking Ja from his frail hold on the surface of the rock, the spear slipped from his fingers, and still clinging to it I plunged feet foremost toward my executioner.

At the instant that he felt the spear come away from Ja’s hand the creature must have opened his huge jaws to catch me, for when I came down, still clinging to the butt end of the weapon, the point yet rested in his mouth and the result was that the sharpened end transfixed his lower jaw.

With the pain he snapped his mouth closed.  I fell upon his snout, lost my hold upon the spear, rolled the length of his face and head, across his short neck onto his broad back and from there to the ground.
