And then to my utter amazement I saw the forehead and eyes of the maiden come slowly out of the depths, following the gaze of the reptile just as when she had disappeared beneath the surface.  On and on came the girl until she stood in water that reached barely to her knees, and though she had been beneath the surface sufficient time to have drowned her thrice over there was no indication, other than her dripping hair and glistening body, that she had been submerged at all.

Again and again the queen led the girl into the depths and out again, until the uncanny weirdness of the thing got on my nerves so that I could have leaped into the tank to the child’s rescue had I not taken a firm hold of myself.

Once they were below much longer than usual, and when they came to the surface I was horrified to see that one of the girl’s arms was gone—­gnawed completely off at the shoulder—­but the poor thing gave no indication of realizing pain, only the horror in her set eyes seemed intensified.

The next time they appeared the other arm was gone, and then the breasts, and then a part of the face—­it was awful.  The poor creatures on the islands awaiting their fate tried to cover their eyes with their hands to hide the fearful sight, but now I saw that they too were under the hypnotic spell of the reptiles, so that they could only crouch in terror with their eyes fixed upon the terrible thing that was transpiring before them.

Finally the queen was under much longer than ever before, and when she rose she came alone and swam sleepily toward her bowlder.  The moment she mounted it seemed to be the signal for the other Mahars to enter the tank, and then commenced, upon a larger scale, a repetition of the uncanny performance through which the queen had led her victim.

Only the women and children fell prey to the Mahars—­they being the weakest and most tender—­and when they had satisfied their appetite for human flesh, some of them devouring two and three of the slaves, there were only a score of full-grown men left, and I thought that for some reason these were to be spared, but such was far from the case, for as the last Mahar crawled to her rock the queen’s thipdars darted into the air, circled the temple once and then, hissing like steam engines, swooped down upon the remaining slaves.

There was no hypnotism here—­just the plain, brutal ferocity of the beast of prey, tearing, rending, and gulping its meat, but at that it was less horrible than the uncanny method of the Mahars.  By the time the thipdars had disposed of the last of the slaves the Mahars were all asleep upon their rocks, and a moment later the great pterodactyls swung back to their posts beside the queen, and themselves dropped into slumber.

“I thought the Mahars seldom, if ever, slept,” I said to Ja.

“They do many things in this temple which they do not do elsewhere,” he replied.  “The Mahars of Phutra are not supposed to eat human flesh, yet slaves are brought here by thousands and almost always you will find Mahars on hand to consume them.  I imagine that they do not bring their Sagoths here, because they are ashamed of the practice, which is supposed to obtain only among the least advanced of their race; but I would wager my canoe against a broken paddle that there is no Mahar but eats human flesh whenever she can get it.”
