It would, of course, be difficult to accomplish this without attracting the attention of the guards, and there was a possibility that the center pole might be set sufficiently far in the ground to render it impossible for him to raise it. If he were given time he could excavate around the base of it, but inasmuch as one or the other of the sentries was continually poking his head into the hut to see that all was well, Tarzan saw little likelihood of his being able to free himself without being discovered.
As darkness settled upon the village Tarzan stretched himself upon the hard dirt floor of the hut and sought to sleep. For some time the noises of the village kept him awake, but at last he slept. How long thereafter it was that he was awakened he did not know. From childhood he had shared with the beasts, among whom he had been raised, the ability to awaken quickly and in full command of all his faculties. He did so now, immediately conscious that the noise that had aroused him came from an animal upon the roof of the hut. Whatever it was, it was working quietly, but to what end the ape-man could not imagine.
The acrid fumes of the village cook fires so filled the air that Tarzan was unable to catch the scent of the creature upon the roof. He carefully reviewed all the possible purposes for which an animal might be upon the thatched, dry-grass roof of the Bagego hut and through a process of elimination he could reach but one conclusion. That was that the thing upon the outside wished to come in and either it did not have brains enough to know that there was a doorway, or else it was too cunning to risk detection by attempting to pass the sentries.
But why should any animal wish to enter the hut? Tarzan lay upon his back, gazing up through the darkness in the direction of the roof above him as he tried to find an answer to his question. Presently, directly above his head, he saw a little ray of moonlight. Whatever it was upon the roof had made an opening that grew larger and larger as the creature quietly tore away the thatching. The aperture was being made close to the wall where the radiating rafters were farthest apart, but whether this was through intent or accident Tarzan could not guess. As the hole grew larger and he caught occasional glimpses of the thing silhouetted against the moonlit sky, a broad smile illuminated the face of the ape-man. Now he saw strong little fingers working at the twigs that were fastened laterally across the rafters to support the thatch and presently, after several of these had been removed, the opening was entirely closed by a furry little body that wriggled through and dropped to the floor close beside the prisoner.
"How did you find me, Nkima?" whispered Tarzan.
"Nkima followed," replied the little monkey. "All day he has been sitting in a high tree above the village watching this place and waiting for darkness. Why do you stay here, Tarzan of the Apes? Why do you not come away with little Nkima?"
"I am fastened here with a chain," said Tarzan. "I cannot come away."
"Nkima will go and bring Muviro and his warriors," said Nkima.
Of course he did not use these words at all, but what he said in the language of the apes conveyed the same meaning to Tarzan. Black apes carrying sharp, long sticks was the expression that he used to describe the Waziri warriors, and the name for Muviro was one of his own coining, but he and Tarzan understood one another.
"No," said Tarzan. "If I am going to need Muviro, he could not get here in time now to be of any help to me. Go back into the forest, Nkima, and wait for me. Perhaps I shall join you very soon."
Nkima scolded, for he did not want to go away. He was afraid alone in this strange forest; in fact, Nkima's life had been one long complex of terror, relieved only by those occasions when he could snuggle in the lap of his master, safe within the solid walls of Tarzan's bungalow. One of the sentries heard the voices within the hut and crawled part way in.
"There," said Tarzan to Nkima, "you see what you have done. Now you had better do as Tarzan tells you and get out of here and into the forest before they catch you and eat you."
"Who are you talking to?" demanded the sentry. He heard a scampering in the darkness and at the same instant he caught sight of the hole in the roof and almost simultaneously he saw something dark go through it and disappear. "What was that?" he demanded, nervously.
"That," said Tarzan, "was the ghost of your grandfather. He came to tell me that you and your wives and all your children would take sick and die if anything happens to me. He also brought the same message for Nyuto."
The sentry trembled. "Call him back," he begged, "and tell him that I had nothing to do with it. It is not I, but Nyuto, the chief, who is going to kill you."
"I cannot call him back," said Tarzan, "and so you had better tell Nyuto not to kill me."
"I cannot see Nyuto until morning," wailed the sentry. "Perhaps then it will be too late."
"No," said Tarzan. "The ghost of your grandfather will not do anything until tomorrow."
Terrified, the sentry returned to his post where Tarzan heard him fearfully and excitedly discussing the matter with his companion until the ape-man finally dropped off to sleep again.
It was late the following morning before anyone entered the hut in which Tarzan was confined. Then came Lukedi with another gourd of milk. He was very much excited.
"Is what Ogonyo says true?" he demanded.
"Who is Ogonyo?" asked Tarzan.
"He was one of the warriors who stood guard here last night, and he has told Nyuto and all the village that he heard the ghost of his grandfather talking with you and that the ghost said that he would kill everyone in the village if you were harmed, and now everyone is afraid."
"And Nyuto?" asked Tarzan.
"Nyuto is not afraid of anything," said Lukedi.
"Not even of ghosts of grandfathers?" asked Tarzan.
"No. He alone of all the Bagegos is not afraid of the men of The Lost Tribe, and now he is very angry at you because you have frightened his people and this evening you are to be burned. Look!" And Lukedi pointed to the low doorway of the hut. "From here you can see them placing the stake to which you are to be bound, and the boys are in the forest gathering fagots."
Tarzan pointed toward the hole in the roof. "There," he said, "is the hole made by the ghost of Ogonyo's grandfather. Fetch Nyuto and let him see. Then, perhaps, he will believe."
"It will make no difference," said Lukedi. "If he saw a thousand ghosts with his own eyes, he would not be afraid. He is very brave, but he is also very stubborn and a fool. Now we shall all die."
"Unquestionably," said Tarzan.
"Can you not save me?" asked Lukedi.
"If you will help me to escape, I promise you that the ghosts shall not harm you."
"Oh, if I could but do it," said Lukedi, as he passed the gourd of milk to the ape-man.
"You bring me nothing but milk," said Tarzan. "Why is that?"
"In this village we belong to the Buliso clan and, therefore, we may not drink the milk nor eat the flesh of Timba, the black cow, so when we have guests or prisoners we save this food for them."
Tarzan was glad that the totem of the Buliso clan was a cow instead of a grasshopper, or rainwater from the roofs of houses or one of the hundreds of other objects that are venerated by different clans, for while Tarzan's early training had not placed grasshoppers beyond the pale as food for men, he much preferred the milk of Timba.
