As month after month had passed and Tarzan had not returned to Opar, as he had promised he would do, to see that no harm befell La, she had come to accept the opinion of Cadj that the ape-man was dead, and though she hated the repulsive Cadj none the less, her love for Tarzan had gradually become little more than a sorrowful memory. Now to learn that he was alive and had been so near was like re-opening an old wound. At first she comprehended little else than that Tarzan had been close to Opar, but presently the cries of Manu aroused her to a realization that the ape-man was in danger—just what the danger was, she did not know. “Who has gone to kill Tarzan of the Apes?” she demanded suddenly. “Cadj, Cadj!” shrieked Manu. “He has gone with many, many men, and is following upon the spoor of Tarzan.” La sprang quickly from the pool, seized her girdle and ornaments from her attendant and adjusting them hurriedly, sped through the garden and into the temple. CHAPTER VII “YOU MUST SACRIFICE HIM” WARILY CADJ and his hundred frightful followers, armed with their bludgeons and knives, crept stealthily down the face of the barrier into the valley below, upon the trail of the white man and his black companions. They made no haste, for they had noted from the summit of Opar’s outer wall, that the party they were pursuing moved very slowly, though why, they did not know, for they had been at too great a distance to see the burden that each of the blacks carried. Nor was it Cadj’s desire to overtake his quarry by daylight, his plans contemplating a stealthy night attack, the suddenness of which, together with the great number of his followers, might easily confuse and overwhelm a sleeping camp. The spoor they followed was well marked. There could be no mistaking it, and they moved slowly down the now gentle declivity, toward the bottom of the valley. It was close to noon that they were brought to a sudden halt by the discovery of a thorn boma recently constructed in a small clearing just ahead of them. From the center of the boma arose the thin smoke of a dying fire. Here, then, was the camp of the ape-man. Cadj drew his followers into the concealment of the thick bushes that bordered the trail, and from there he sent ahead a single man to reconnoiter. It was but a few moments later that the latter returned to say that the camp was deserted, and once again Cadj moved forward with his men. Entering the boma they examined it in an effort to estimate the size of the party that accompanied Tarzan. As they were thus occupied Cadj saw something lying half concealed by bushes at the far end of the boma. Very warily he approached it, for there was that about it which not only aroused his curiosity but prompted him to caution, for it resembled indistinctly the figure of a man, lying huddled upon the ground.
