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.
