Motionless as a bronze statue was the wily ape-man, for well he knew how wary is Pisah, the fish. The slightest movement would frighten him away and only by infinite patience might he be captured at all. Tarzan depended upon his own quickness and the suddenness of his attack, for he had no bait or hook. His knowledge of the ways of the denizens of the water told him where to wait for Pisah. It might be a minute or it might be an hour before the fish would swim into the little pool above which he crouched, but sooner or later one would come. That the ape-man knew, so with the patience of the beast of prey he waited for his quarry.
At last there was a glint of shiny scales. Pisah was coming. In a moment he would be within reach and then with the swiftness of light two strong, brown hands would plunge into the pool and seize him, but, just at the moment that the fish was about to come within reach, there was a great crashing in the underbrush behind the ape-man. Instantly Pisah was gone and Tarzan, growling, had wheeled about to face whatever creature might be menacing him. The moment that he turned he saw that the author of the disturbance was Zu-tag.
"What does Zu-tag want?" asked the ape-man.
"Zu-tag comes to the water to drink," replied the ape.
"Where is the tribe?" asked Tarzan.
"They are hunting for pisangs and scimatines farther back in the forest," replied Zu-tag.
"And the Tarmangani she and bull—" asked Tarzan, "are they safe?"
"They have gone away," replied Zu-tag. "Kudu has come out of his lair twice since they left."
"Did the tribe chase them away?" asked Tarzan.
"No," replied the ape. "We did not see them go. We do not know why they left."
Tarzan swung quickly through the trees toward the clearing. The hut and boma were as he had left them, but there was no sign of either the man or the woman. Crossing the clearing, he entered the boma and then the hut. Both were empty, and his trained nostrils told him that they had been gone for at least two days. As he was about to leave the hut he saw a paper pinned upon the wall with a sliver of wood and taking it down, he read:
After what you told me about Miss Kircher, and knowing that you dislike her, I feel that it is not fair to her and to you that we should impose longer upon you. I know that our presence is keeping you from continuing your journey to the west coast, and so I have decided that it is better for us to try and reach the white settlements immediately without imposing further upon you. We both thank you for your kindness and protection. If there was any way that I might repay the obligation I feel, I should be only too glad to do so.
It was signed by Lieutenant Harold Percy Smith-Oldwick.
Tarzan shrugged his shoulders, crumpled the note in his hand and tossed it aside. He felt a certain sense of relief from responsibility and was glad that they had taken the matter out of his hands. They were gone and would forget, but somehow he could not forget. He walked out across the boma and into the clearing. He felt uneasy and restless. Once he started toward the north in response to a sudden determination to continue his way to the west coast. He would follow the winding river toward the north a few miles where its course turned to the west and then on toward its source across a wooded plateau and up into the foothills and the mountains. Upon the other side of the range he would search for a stream running downward toward the west coast, and thus following the rivers he would be sure of game and water in plenty.
But he did not go far. A dozen steps, perhaps, and he came to a sudden stop. "He is an Englishman," he muttered, "and the other is a woman. They can never reach the settlements without my help. I could not kill her with my own hands when I tried, and if I let them go on alone, I will have killed her just as surely as though I had run my knife into her heart. No," and again he shook his head. "Tarzan of the Apes is a fool and a weak, old woman," and he turned back toward the south.
Manu, the monkey, had seen the two Tarmangani pass two days before. Chattering and scolding, he told Tarzan all about it. They had gone in the direction of the village of the Gomangani, that much had Manu seen with his own eyes, so the ape-man swung on through the jungle in a southerly direction and though with no concentrated effort to follow the spoor of those he trailed, he passed numerous evidences that they had gone this way—faint suggestions of their scent spoor clung lightly to leaf or branch or bole that one or the other had touched, or in the earth of the trail their feet had trod, and where the way wound through the gloomy depth of dank forest, the impress of their shoes still showed occasionally in the damp mass of decaying vegetation that floored the way.
An inexplicable urge spurred Tarzan to increasing, speed. The same still, small voice that chided him for having neglected them seemed constantly whispering that they were in dire need of him now. Tarzan's conscience was troubling him, which accounted for the fact that he compared himself to a weak, old woman, for the ape-man, reared in savagery and inured to hardships and cruelty, disliked to admit any of the gentler traits that in reality were his birthright.
The trail made a detour to the east of the village of the Wamabos, and then returned to the wide elephant path nearer to the river, where it continued in a southerly direction for several miles. At last there came to the ears of the ape-man a peculiar whirring, throbbing sound. For an instant he paused, listening intently, "An aeroplane!" he muttered, and hastened forward at greatly increased speed.
When Tarzan of the Apes finally reached the edge of the meadowland where Smith-Oldwick's plane had landed, he took in the entire scene in one quick glance and grasped the situation, although he could scarce give credence to the things he saw. Bound and helpless, the English officer lay upon the ground at one side of the meadow, while around him stood a number of the black deserters from the German command. Tarzan had seen these men before and knew who they were. Coming toward him down the meadow was an aeroplane piloted by the black Usanga and in the seat behind the pilot was the white girl, Bertha Kircher. How it befell that the ignorant savage could operate the plane, Tarzan could not guess nor had he time in which to speculate upon the subject. His knowledge of Usanga, together with the position of the white man, told him that the black sergeant was attempting to carry off the white girl. Why he should be doing this when he had her in his power and had also captured and secured the only creature in the jungle who might wish to defend her in so far as the black could know, Tarzan could not guess, for he knew nothing of Usanga's twenty-four dream wives nor of the black's fear of the horrid temper of Naratu, his present mate. He did not know, then, that Usanga had determined to fly away with the white girl never to return, and to put so great a distance between himself and Naratu that the latter never could find him again; but it was this very thing that was in the black's mind although not even his own warriors guessed it. He had told them that he would take the captive to a sultan of the north and there obtain a great price for her and that when he returned they should have some of the spoils.
These things Tarzan did not know. All he knew was what he saw—a Negro attempting to fly away with a white girl. Already the machine was slowly leaving the ground. In a moment more it would rise swiftly out of reach. At first Tarzan thought of fitting an arrow to his bow and slaying Usanga, but as quickly he abandoned the idea because he knew that the moment the pilot was slain the machine, running wild, would dash the girl to death among the trees.
There was but one way in which he might hope to succor her—a way which if it failed must send him to instant death and yet he did not hesitate in an attempt to put it into execution.
