THE TARZAN OF THE APES SERIES (ILLUSTRATED). Edgar Rice Burroughs

of savages—just a silent messenger of death from out of the silent forest.

      The Arabs and their followers were thrown into a fine rage at this unprecedented occurrence. They ran for the gates, to wreak dire vengeance upon the foolhardy perpetrator of the outrage; but they suddenly realized that they did not know which way to turn to find the foe. As they stood debating with many angry shouts and much gesticulating, one of the Arabs sank silently to the ground in their very midst—a thin arrow protruding from his heart.

      Tarzan had placed the finest marksmen of the tribe in the surrounding trees, with directions never to reveal themselves while the enemy was faced in their direction. As a black released his messenger of death he would slink behind the sheltering stem of the tree he had selected, nor would he again aim until a watchful eye told him that none was looking toward his tree.

      Three times the Arabs started across the clearing in the direction from which they thought the arrows came, but each time another arrow would come from behind to take its toll from among their number.

      Then they would turn and charge in a new direction. Finally they set out upon a determined search of the forest, but the blacks melted before them, so that they saw no sign of an enemy.

      But above them lurked a grim figure in the dense foliage of the mighty trees—it was Tarzan of the Apes, hovering over them as if he had been the shadow of death. Presently a Manyuema forged ahead of his companions; there was none to see from what direction death came, and so it came quickly, and a moment later those behind stumbled over the dead body of their comrade —the inevitable arrow piercing the still heart.

      It does not take a great deal of this manner of warfare to get upon the nerves of white men, and so it is little to be wondered at that the Manyuema were soon panic-stricken. Did one forge ahead an arrow found his heart; did one lag behind he never again was seen alive; did one stumble to one side, even for a bare moment from the sight of his fellows, he did not return —and always when they came upon the bodies of their dead they found those terrible arrows driven with the accuracy of superhuman power straight through the victim's heart. But worse than all else was the hideous fact that not once during the morning had they seen or heard the slightest sign of an enemy other than the pitiless arrows.

      When finally they returned to the village it was no better. Every now and then, at varying intervals that were maddening in the terrible suspense they caused, a man would plunge forward dead.

      The blacks besought their masters to leave this terrible place, but the Arabs feared to take up the march through the grim and hostile forest beset by this new and terrible enemy while laden with the great store of ivory they had found within the village; but, worse yet, they hated to leave the ivory behind.

      Finally the entire expedition took refuge within the thatched huts— here, at least, they would be free from the arrows. Tarzan, from the tree above the village, had marked the hut into which the chief Arabs had gone, and, balancing himself upon an overhanging limb, he drove his heavy spear with all the force of his giant muscles through the thatched roof. A howl of pain told him that it had found a mark. With this parting salute to convince them that there was no safety for them anywhere within the country, Tarzan returned to the forest, collected his warriors, and withdrew a mile to the south to rest and eat. He kept sentries in several trees that commanded a view of the trail toward the village, but there was no pursuit.

      An inspection of his force showed not a single casualty—not even a minor wound; while rough estimates of the enemies' loss convinced the blacks that no fewer than twenty had fallen before their arrows.

      They were wild with elation, and were for finishing the day in one glorious rush upon the village, during which they would slaughter the last of their foemen. They were even picturing the various tortures they would inflict, and gloating over the suffering of the Manyuema, for whom they entertained a peculiar hatred, when Tarzan put his foot down flatly upon the plan.

      "You are crazy!" he cried. "I have shown you the only way to fight these people. Already you have killed twenty of them without the loss of a single warrior, whereas, yesterday, following your own tactics, which you would now renew, you lost at least a dozen, and killed not a single Arab or Manyuema. You will fight just as I tell you to fight, or I shall leave you and go back to my own country." They were frightened when he threatened this, and promised to obey him scrupulously if he would but promise not to desert them.

      "Very well," he said. "We shall return to the elephant boma for the night. I have a plan to give the Arabs a little taste of what they may expect if they remain in our country, but I shall need no help. Come! If they suffer no more for the balance of the day they will feel reassured, and the relapse into fear will be even more nerve-racking than as though we continued to frighten them all afternoon." So they marched back to their camp of the previous night, and, lighting great fires, ate and recounted the adventures of the day until long after dark. Tarzan slept until midnight, then he arose and crept into the Cimmerian blackness of the forest. An hour later he came to the edge of the clearing before the village. There was a camp-fire burning within the palisade. The ape-man crept across the clearing until he stood before the barred gates. Through the interstices he saw a lone sentry sitting before the fire.

      Quietly Tarzan went to the tree at the end of the village street.

      He climbed softly to his place, and fitted an arrow to his bow.

      For several minutes he tried to sight fairly upon the sentry, but the waving branches and flickering firelight convinced him that the danger of a miss was too great—he must touch the heart full in the center to bring the quiet and sudden death his plan required.

      He had brought, besides, his bow, arrows, and rope, the gun he had taken the previous day from the other sentry he had killed. Caching all these in a convenient crotch of the tree, he dropped lightly to the ground within the palisade, armed only with his long knife.

      The sentry's back was toward him. Like a cat Tarzan crept upon the dozing man. He was within two paces of him now—another instant and the knife would slide silently into the fellow's heart.

      Tarzan crouched for a spring, for that is ever the quickest and surest attack of the jungle beast—when the man, warned, by some subtle sense, sprang to his feet and faced the ape-man.
