He smirked knowingly, and the anger in the girl flashed out.

"You scoundrel! For a man of your position to stoop so low as to steal and lie! Oh, I know the whole story now! You stole those papers from my father, your friend, as he was dying; but you didn't steal them all, Dr. Sigurd Krausz! Poor fool of a thief that you are, not even to know a fort from a slave barracoon—and yet you call yourself an archaeologist! Why, you don't even know what the treasure is yet, the best part of it, nor where it is, nor where the real fort is! And you never will know. Now, either send Mr. Hammer and Mr. Solomon safely out with me, or I'll——"

"Beggin' your pardon, miss, but if so be as I could smoke it'd be a mortal help!"

The words were a desperate effort on the part of Solomon to save the situation. So rapidly had the furious girl poured out her denunciation that before Hammer realized what she was saying, before any one could intervene, she had given away the secret.

Solomon's words, however, and the look that he flashed her, saved her from letting Krausz know any more. It was all-important that he should not know that they had men in the jungle ready to spring at his throat.

As she realized what she had said she went deadly pale; but there was no wavering in her eyes, and Hammer, dismayed though he was, could not but approve her for it. Krausz, too, caught the meaning of her words, but more slowly.

As he grasped their import his face changed from red to white, and a snarl came into his eyes; then he sank into his camp-chair, gazing steadily at her as he forced himself into control and tried to read meaning into her words.

"You know the whole story now—so! And they were not all stolen, yess? But what iss thiss—that I do not know a fort from a slave barracoon—Himmel! That iss why we found nothing! And, fräulein, you know all these things, yess?"

"I do, and you shall not know them."

"Listen, fräulein!" He leaned forward, sweat dripping from his face, and earnestness in every feature, while the ribbon of muscle on his brow pounded furiously.
