"Why? What's going on up yonder? And where are we, anyway?"Beneath the great teocalli, Ixtli made answer in his disjointed way of speaking. There the evil-minded paba, Tlacopa, reigned supreme. And there, almost directly above their heads, stood the sacrificial stone, upon whose flat surface the Sun Children would be doomed to suffer the last penalty, provided Tlacopa won his wicked will.

Bruno thrilled to his centre with fierce indignation as he, little by little, gathered this information. Perish by such hideous methods? Give up her fair young life--For, rather queerly, considering that Ixtli spoke of both Victo and Glady, he now had thought of--could see but that one lovely face and shrinking figure,--face and form of the daughter alone.

Discovery might have come all too soon, but for Ixtli's slipping a palm over those indignant lips and thus smothering the outbreak which the young man could not avoid; then, recalled to ordinary prudence, Bruno talked and listened by turns.

Ixtli contrived to make his white brother understand just how they were situated at the time: in a secret channel of communication with the great war temple, through which sanctuary he had hoped to lead his friend, thence to escape from the valley itself, if a favourable chance should offer. Now their way was barred, and they could only wait. Unless--would Bruno keep close guard over his tongue?

Yes. Anything, rather than remain wholly idle, like this.

Adding a few minor cautions, Ixtli took Gillespie by a wrist, and stole noiselessly forward, climbing upward, over and into a contrivance which Bruno vainly sought to recognise by the sense of touch, but giving a thrill of amazement when his guide paused long enough to whisper in his nearest ear:

"Dis war-god body. Stand up in teocalli, look on kill-stone.

Wait; you see, hear, all dat, now!"

Thanks to the close association of that night, with all its attendant perils, Bruno was growing fairly skilful in interpreting the broken sentences of his copper-hued chum, and he now knew they were moving about within the hollow image of the Aztecan war-god, Huitzilopochtli, while--He caught sight of several small apertures, through which yellow light came dimly, and, almost without thinking, applied his eyes to the one most convenient, peering forth upon the broad sacrificial stone, with its foul, blood-stained surface, the little channels intended to drain off the superfluous hemorrhage, together with the gloomy, repulsive surroundings. And, too, a most abominable stench appeared to rise from the altar of death, and Bruno shrunk back with a shiver of disgust.

"No talk loud!" softly breathed Ixtli, gripping an arm with force. "Dey kill, if find now. Look, dat one Tlacopa; big priest, you call. DEM help paba fool all people; so!"Although his meaning was not fully apparent, Bruno caught renewed interest, and once more peered forth upon the scene, weird and impressive enough, even from a Christian point of view.

Headed by Tlacopa, a ceremony of some deion was taking place, lesser priests and other acolytes performing their various parts, the incantations rising now loudly, now sinking to a hollow monotone, the whole affair being none the less absorbing when Bruno remembered that, perhaps, it might have some connection with the vile plots against the Sun Children, if not endangering life itself.

Gillespie likewise took note of various other graven images;among them one of the not less hideous war-goddess, Teoyaomiqui, or "divine war death," fitting consort for the mighty "humming-bird" himself.

Meanwhile, Ixtli, who appeared to look upon the whole affair as a more or less jolly good jest at the expense of his superstitious people, took occasion to give his white brother a few pointers, letting him see how easy it was for false oracles to be manufactured to order; how certain the lightest wishes of the head priest were to find speedy fulfilment at all times.

While thus divulging part of the mysteries of the temple, that ceremony reached a finale, and the little crowd slowly melted away, leaving but Tlacopa and a select few of his trusted henchman. And Ixtli certainly caught enough of their talk to alter his manner most materially.

"Come, quick!" he fiercely whispered in Bruno's ear, gripping an arm, and fairly forcing the young man to accompany his retreat.

Not another word was spoken before the lower level was reached, and then Gillespie broke the ice, asking what was the matter.

Dark though it was all around them, Bruno could tell by sense of touch that his guide was powerfully agitated, and, though Ixtli clearly hesitated before imparting the asked-for information, persistence won the point; and then--Imperfectly though that discovery was set forth, Gillespie contrived to gather this much: Tlacopa decreed that the Sun Children should be brought to trial, if not to actual execution, when the morning sun arose!

"Never!" fiercely vowed Bruno, all on fire, as he recalled that more than fair face. "Never,--while I live and draw breath!"
