And there we found them!
There was never another such sight! It made our blood run cold once more, rather with surprise than fear, though the latter quickly followed.
Ranged along the farther side of the cavern, and visible in the light of another glowing heap in the center, were as many as thirty of those huge hairy creatures, standing shoulder to shoulder, their great eyes glaring like bull's-eye lanterns. But the thing that filled us with terror was their motions.
You have read, with thrilling nerves, how a huge cobra, reared on his coils, sways his terrible head from side to side before striking. Well, all those black heads before us were swaying in unison, but with a sickening circular movement, which was regularly reversed in direction. Three times by the right and then three times by the left those heads circled, in rhythmic cadence, while the luminous eyes seemed to leave phosphorescent rings in the air, intersecting one another in consequence of the rapidity of the motion.
It was such a spectacle as I had never beheld in the wildest dream. It was baleful. It was the charm of the serpent fascinating his terrified prey. In an instant I felt my brain turning, and I staggered in spite of my utmost efforts. A kind of paralysis stiffened my limbs.
Presently, all moving together, and uttering a hissing, whistling sound, they began slowly to approach us, keeping in line, each shaggy leg lifted at the same moment, like so many soldiers on parade, while the heads continued to swing, and the glowing eyes to cut linked circles in the air. But for Edmund we should certainly have been lost. Standing a little to the fore, he spoke to us over his shoulder, in a low voice:
"Take out your pistols, but don't shoot unless they make a rush. Then kill as many as you can. I'll knock over the leader in the center, and I think that will be enough."
We could as easily have stirred our arms if we had been marble statues, but he promptly raised his pistol, and the explosion followed on the instant. The report was like an earthquake. It shocked us into our senses and almost out of them again. The weight of the air and the confinement of the cavern magnified and concentrated the sound so that it was awful beyond belief. The fellow in the center was hurled back as if shot from a catapult, and the others fell at flat as he, and lay there groveling, their big eyes filming and swaying, but no longer in unison.
The charm was broken, and as we saw our fearful enemies prostrate, our courage returned at a bound.
"I thought as much," said Edmund coolly. "But I'm sorry now that I aimed at that fellow; the sound alone would have sufficed. It was not necessary to take life. However, we should probably have had to come to it eventually, and now we have them thoroughly cowed. Our safety consists in keeping them terrified."
