“What means this?” asked a low voice in their ears.

They were given no time to reply, however, for at the sound of that voice the young woman had sprung to her feet and with a little cry of joy leaped toward their assailant.

“Tarzan!” she cried.

The ape-man hurled the two sailors across the deck, where they rolled, stunned and terrified, into the scuppers upon the opposite side, and with an exclamation of incredulity gathered the girl into his arms.

Brief, however, were the moments for their greeting.

Scarcely had they recognized one another than the clouds above them parted to show the figures of a half-dozen men clambering over the side of the Kincaid to the steamer’s deck.

Foremost among them was the Russian. As the brilliant rays of the equatorial moon lighted the deck, and he realized that the man before him was Lord Greystoke, he screamed hysterical commands to his followers to fire upon the two.

Tarzan pushed Jane behind the cabin near which they had been standing, and with a quick bound started for Rokoff. The men behind the Russian, at least two of them, raised their rifles and fired at the charging ape-man; but those behind them were otherwise engaged—for up the monkey-ladder in their rear was thronging a hideous horde.

First came five snarling apes, huge, manlike beasts, with bared fangs and slavering jaws; and after them a giant black warrior, his long spear gleaming in the moonlight.

Behind him again scrambled another creature, and of all the horrid horde it was this they most feared—Sheeta, the panther, with gleaming jaws agape and fiery eyes blazing at them in the mightiness of his hate and of his blood lust.
