It meant nothing to Tarzan, of course, for he could not tell one language from another, so when he pointed to the word man which he had printed upon a piece of bark he learned from D'Arnot that it was p.r.o.nounced HOMME, and in the same way he was taught to p.r.o.nounce ape, SINGE and tree, ARBRE.

He was a most eager student, and in two more days had mastered so much French that he could speak little sentences such as: "That is a tree,"

"this is gra.s.s," "I am hungry," and the like, but D'Arnot found that it was difficult to teach him the French construction upon a foundation of English.

The Frenchman wrote little lessons for him in English and had Tarzan repeat them in French, but as a literal translation was usually very poor French Tarzan was often confused.

D'Arnot realized now that he had made a mistake, but it seemed too late to go back and do it all over again and force Tarzan to unlearn all that he had learned, especially as they were rapidly approaching a point where they would be able to converse.

On the third day after the fever broke Tarzan wrote a message asking D'Arnot if he felt strong enough to be carried back to the cabin.

Tarzan was as anxious to go as D'Arnot, for he longed to see Jane again.

It had been hard for him to remain with the Frenchman all these days for that very reason, and that he had unselfishly done so spoke more glowingly of his n.o.bility of character than even did his rescuing the French officer from Mbonga's clutches.

D'Arnot, only too willing to attempt the journey, wrote:

But you cannot carry me all the distance through this tangled forest.

Tarzan laughed.

"MAIS OUI," he said, and D'Arnot laughed aloud to hear the phrase that he used so often glide from Tarzan's tongue.

So they set out, D'Arnot marveling as had Clayton and Jane at the wondrous strength and agility of the apeman.

Mid-afternoon brought them to the clearing, and as Tarzan dropped to earth from the branches of the last tree his heart leaped and bounded against his ribs in antic.i.p.ation of seeing Jane so soon again.

No one was in sight outside the cabin, and D'Arnot was perplexed to note that neither the cruiser nor the Arrow was at anchor in the bay.

An atmosphere of loneliness pervaded the spot, which caught suddenly at both men as they strode toward the cabin.

Neither spoke, yet both knew before they opened the closed door what they would find beyond.

Tarzan lifted the latch and pushed the great door in upon its wooden hinges. It was as they had feared. The cabin was deserted.

The men turned and looked at one another. D'Arnot knew that his people thought him dead; but Tarzan thought only of the woman who had kissed him in love and now had fled from him while he was serving one of her people.

A great bitterness rose in his heart. He would go away, far into the jungle and join his tribe. Never would he see one of his own kind again, nor could he bear the thought of returning to the cabin. He would leave that forever behind him with the great hopes he had nursed there of finding his own race and becoming a man among men.

And the Frenchman? D'Arnot? What of him? He could get along as Tarzan had. Tarzan did not want to see him more. He wanted to get away from everything that might remind him of Jane.

As Tarzan stood upon the threshold brooding, D'Arnot had entered the cabin. Many comforts he saw that had been left behind. He recognized numerous articles from the cruiser--a camp oven, some kitchen utensils, a rifle and many rounds of ammunition, canned foods, blankets, two chairs and a cot--and several books and periodicals, mostly American.

"They must intend returning," thought D'Arnot.

He walked over to the table that John Clayton had built so many years before to serve as a desk, and on it he saw two notes addressed to Tarzan of the Apes.

One was in a strong masculine hand and was unsealed. The other, in a woman's hand, was sealed.

"Here are two messages for you, Tarzan of the Apes," cried D'Arnot, turning toward the door; but his companion was not there.

D'Arnot walked to the door and looked out. Tarzan was nowhere in sight. He called aloud but there was no response.

"MON DIEU!" exclaimed D'Arnot, "he has left me. I feel it. He has gone back into his jungle and left me here alone."

And then he remembered the look on Tarzan's face when they had discovered that the cabin was empty--such a look as the hunter sees in the eyes of the wounded deer he has wantonly brought down.

The man had been hard hit--D'Arnot realized it now--but why? He could not understand.

The Frenchman looked about him. The loneliness and the horror of the place commenced to get on his nerves--already weakened by the ordeal of suffering and sickness he had pa.s.sed through.

To be left here alone beside this awful jungle--never to hear a human voice or see a human face--in constant dread of savage beasts and more terribly savage men--a prey to solitude and hopelessness. It was awful.

And far to the east Tarzan of the Apes was speeding through the middle terrace back to his tribe. Never had he traveled with such reckless speed. He felt that he was running away from himself--that by hurtling through the forest like a frightened squirrel he was escaping from his own thoughts. But no matter how fast he went he found them always with him.

He pa.s.sed above the sinuous body of Sabor, the lioness, going in the opposite direction--toward the cabin, thought Tarzan.

What could D'Arnot do against Sabor--or if Bolgani, the gorilla, should come upon him--or Numa, the lion, or cruel Sheeta?

Tarzan paused in his flight.

"What are you, Tarzan?" he asked aloud. "An ape or a man?"

"If you are an ape you will do as the apes would do--leave one of your kind to die in the jungle if it suited your whim to go elsewhere.

"If you are a man, you will return to protect your kind. You will not run away from one of your own people, because one of them has run away from you."

D'Arnot closed the cabin door. He was very nervous. Even brave men, and D'Arnot was a brave man, are sometimes frightened by solitude.

He loaded one of the rifles and placed it within easy reach. Then he went to the desk and took up the unsealed letter addressed to Tarzan.

Possibly it contained word that his people had but left the beach temporarily. He felt that it would be no breach of ethics to read this letter, so he took the enclosure from the envelope and read:

TO TARZAN OF THE APES:

We thank you for the use of your cabin, and are sorry that you did not permit us the pleasure of seeing and thanking you in person.

We have harmed nothing, but have left many things for you which may add to your comfort and safety here in your lonely home.

If you know the strange white man who saved our lives so many times, and brought us food, and if you can converse with him, thank him, also, for his kindness.

We sail within the hour, never to return; but we wish you and that other jungle friend to know that we shall always thank you for what you did for strangers on your sh.o.r.e, and that we should have done infinitely more to reward you both had you given us the opportunity.

Very respectfully, WM. CECIL CLAYTON.

"'Never to return,'" muttered D'Arnot, and threw himself face downward upon the cot.
