The letters he could scarcely decipher for he had learned little or nothing of script, so he put them back in the box with the photograph and turned his attention to the book.

This was almost entirely filled with fine script, but while the little bugs were all familiar to him, their arrangement and the combinations in which they occurred were strange, and entirely incomprehensible.

Tarzan had long since learned the use of the dictionary, but much to his sorrow and perplexity it proved of no avail to him in this emergency. Not a word of all that was writ in the book could he find, and so he put it back in the metal box, but with a determination to work out the mysteries of it later on.

Little did he know that this book held between its covers the key to his origin—the answer to the strange riddle of his strange life. It was the diary of John Clayton, Lord Greystoke—kept in French, as had always been his custom.

Tarzan replaced the box in the cupboard, but always thereafter he carried the features of the strong, smiling face of his father in his heart, and in his head a fixed determination to solve the mystery of the strange words in the little black book.

At present he had more important business in hand, for his supply of arrows was exhausted, and he must needs journey to the black men’s village and renew it.

Early the following morning he set out, and, traveling rapidly, he came before midday to the clearing. Once more he took up his position in the great tree, and, as before, he saw the women in the fields and the village street, and the cauldron of bubbling poison directly beneath him.

For hours he lay awaiting his opportunity to drop down unseen and gather up the arrows for which he had come; but nothing now occurred to call the villagers away from their homes. The day wore on, and still Tarzan of the Apes crouched above the unsuspecting woman at the cauldron.

Presently the workers in the fields returned. The hunting warriors emerged from the forest, and when all were within the palisade the gates were closed and barred.

Many cooking pots were now in evidence about the village. Before each hut a woman presided over a boiling stew, while little cakes of plantain, and cassava puddings were to be seen on every hand.
