"No writings in the cabin that might have told something of the lives of its original inmates?"

"I have read everything that was in the cabin with the exception of one book which I know now to be written in a language other than English.

Possibly you can read it."

Tarzan fished the little black diary from the bottom of his quiver, and handed it to his companion.

D'Arnot glanced at the t.i.tle page.

"It is the diary of John Clayton, Lord Greystoke, an English n.o.bleman, and it is written in French," he said.

Then he proceeded to read the diary that had been written over twenty years before, and which recorded the details of the story which we already know--the story of adventure, hardships and sorrow of John Clayton and his wife Alice, from the day they left England until an hour before he was struck down by Kerchak.

D'Arnot read aloud. At times his voice broke, and he was forced to stop reading for the pitiful hopelessness that spoke between the lines.

Occasionally he glanced at Tarzan; but the ape-man sat upon his haunches, like a carven image, his eyes fixed upon the ground.

Only when the little babe was mentioned did the tone of the diary alter from the habitual note of despair which had crept into it by degrees after the first two months upon the sh.o.r.e.

Then the pa.s.sages were tinged with a subdued happiness that was even sadder than the rest.

One entry showed an almost hopeful spirit.

To-day our little boy is six months old. He is sitting in Alice's lap beside the table where I am writing--a happy, healthy, perfect child.

Somehow, even against all reason, I seem to see him a grown man, taking his father's place in the world--the second John Clayton--and bringing added honors to the house of Greystoke.

There--as though to give my prophecy the weight of his endors.e.m.e.nt--he has grabbed my pen in his chubby fists and with his inkbegrimed little fingers has placed the seal of his tiny finger prints upon the page.

And there, on the margin of the page, were the partially blurred imprints of four wee fingers and the outer half of the thumb.

When D'Arnot had finished the diary the two men sat in silence for some minutes.

"Well! Tarzan of the Apes, what think you?" asked D'Arnot. "Does not this little book clear up the mystery of your parentage?

"Why man, you are Lord Greystoke."

"The book speaks of but one child," he replied. "Its little skeleton lay in the crib, where it died crying for nourishment, from the first time I entered the cabin until Professor Porter's party buried it, with its father and mother, beside the cabin.

"No, that was the babe the book speaks of--and the mystery of my origin is deeper than before, for I have thought much of late of the possibility of that cabin having been my birthplace. I am afraid that Kala spoke the truth," he concluded sadly.

D'Arnot shook his head. He was unconvinced, and in his mind had sprung the determination to prove the correctness of his theory, for he had discovered the key which alone could unlock the mystery, or consign it forever to the realms of the unfathomable.

A week later the two men came suddenly upon a clearing in the forest.

In the distance were several buildings surrounded by a strong palisade.

Between them and the enclosure stretched a cultivated field in which a number of negroes were working.

The two halted at the edge of the jungle.

Tarzan fitted his bow with a poisoned arrow, but D'Arnot placed a hand upon his arm.

"What would you do, Tarzan?" he asked.

"They will try to kill us if they see us," replied Tarzan. "I prefer to be the killer."

"Maybe they are friends," suggested D'Arnot.

"They are black," was Tarzan's only reply.

And again he drew back his shaft.

"You must not, Tarzan!" cried D'Arnot. "White men do not kill wantonly. MON DIEU! but you have much to learn.

"I pity the ruffian who crosses you, my wild man, when I take you to Paris. I will have my hands full keeping your neck from beneath the guillotine."

Tarzan lowered his bow and smiled.

"I do not know why I should kill the blacks back there in my jungle, yet not kill them here. Suppose Numa, the lion, should spring out upon us, I should say, then, I presume: Good morning, Monsieur Numa, how is Madame Numa; eh?"

"Wait until the blacks spring upon you," replied D'Arnot, "then you may kill them. Do not a.s.sume that men are your enemies until they prove it."

"Come," said Tarzan, "let us go and present ourselves to be killed,"

and he started straight across the field, his head high held and the tropical sun beating upon his smooth, brown skin.

Behind him came D'Arnot, clothed in some garments which had been discarded at the cabin by Clayton when the officers of the French cruiser had fitted him out in more presentable fashion.

Presently one of the blacks looked up, and beholding Tarzan, turned, shrieking, toward the palisade.

In an instant the air was filled with cries of terror from the fleeing gardeners, but before any had reached the palisade a white man emerged from the enclosure, rifle in hand, to discover the cause of the commotion.

What he saw brought his rifle to his shoulder, and Tarzan of the Apes would have felt cold lead once again had not D'Arnot cried loudly to the man with the leveled gun:

"Do not fire! We are friends!"

"Halt, then!" was the reply.

"Stop, Tarzan!" cried D'Arnot. "He thinks we are enemies."

Tarzan dropped into a walk, and together he and D'Arnot advanced toward the white man by the gate.

The latter eyed them in puzzled bewilderment.

"What manner of men are you?" he asked, in French.

"White men," replied D'Arnot. "We have been lost in the jungle for a long time."

The man had lowered his rifle and now advanced with outstretched hand.
