But how was he to span the crocodile-infested waters? There was no canoe nearer than the Mosula village, and Paulvitch was none too sure that the Kincaid would still be at anchor in the river when he returned should he take the time to traverse the jungle to the distant village and return with a canoe. Yet there was no other way, and so, convinced that thus alone might he hope to reach his prey, Paulvitch, with a parting scowl at the two figures upon the Kincaid’s deck, turned away from the river.

Hastening through the dense jungle, his mind centred upon his one fetich—revenge—the Russian forgot even his terror of the savage world through which he moved.

Baffled and beaten at every turn of Fortune’s wheel, reacted upon time after time by his own malign plotting, the principal victim of his own criminality, Paulvitch was yet so blind as to imagine that his greatest happiness lay in a continuation of the plottings and schemings which had ever brought him and Rokoff to disaster, and the latter finally to a hideous death.

As the Russian stumbled on through the jungle toward the Mosula village there presently crystallized within his brain a plan which seemed more feasible than any that he had as yet considered.

He would come by night to the side of the Kincaid, and once aboard, would search out the members of the ship’s original crew who had survived the terrors of this frightful expedition, and enlist them in an attempt to wrest the vessel from Tarzan and his beasts.

In the cabin were arms and ammunition, and hidden in a secret receptacle in the cabin table was one of those infernal machines, the construction of which had occupied much of Paulvitch’s spare time when he had stood high in the confidence of the Nihilists of his native land.

That was before he had sold them out for immunity and gold to the police of Petrograd. Paulvitch winced as he recalled the denunciation of him that had fallen from the lips of one of his former comrades ere the poor devil expiated his political sins at the end of a hempen rope.

But the infernal machine was the thing to think of now. He could do much with that if he could but get his hands upon it. Within the little hardwood case hidden in the cabin table rested sufficient potential destructiveness to wipe out in the fraction of a second every enemy aboard the Kincaid.

Paulvitch licked his lips in anticipatory joy, and urged his tired legs to greater speed that he might not be too late to the ship’s anchorage to carry out his designs.

All depended, of course, upon when the Kincaid departed. The Russian realized that nothing could be accomplished beneath the light of day. Darkness must shroud his approach to the ship’s side, for should he be sighted by Tarzan or Lady Greystoke he would have no chance to board the vessel.
