is left nearest the great heart. They
had hunted together now for some time, so that they worked in unison,
with only low, purring sounds as signals.

For a moment they lay quite silent near their prey, and then at a sign
from the ape-man Sheeta sprang upon the great back, burying his strong
teeth in the bull's neck. Instantly the brute sprang to his feet with
a bellow of pain and rage, and at the same instant Tarzan rushed in
upon his left side with the stone knife, striking repeatedly behind the
shoulder.

One of the ape-man's hands clutched the thick mane, and as the bull
raced madly through the reeds the thing striking at his life was
dragged beside him. Sheeta but clung tenaciously to his hold upon the
neck and back, biting deep in an effort to reach the spine.

For several hundred yards the bellowing bull carried his two savage
antagonists, until at last the blade found his heart, when with a final
bellow that was half-scream he plunged headlong to the earth. Then
Tarzan and Sheeta feasted to repletion.

After the meal the two curled up together in a thicket, the man's black
head pillowed upon the tawny side of the panther. Shortly after dawn
they awoke and ate again, and then returned to the beach that Tarzan
might lead the balance of the pack to the kill.

When the meal was done the brutes were for curling up to sleep, so
Tarzan and Mugambi set off in search of the Ugambi River. They had
proceeded scarce a hundred yards when they came suddenly upon a broad
stream, which the Negro instantly recognized as that down which he and
his warriors had paddled to the sea upon their ill-starred expedition.

The two now followed the stream down to the ocean, finding that it
emptied into a bay not over a mile from the point upon the beach at
which the canoe had been thrown the night before.

Tarzan was much elated by the discovery, as he knew that in the
vicinity of a large watercourse he should find natives, and from some
of these he had little doubt but that he should obtain news of Rokoff
and the child, for he felt reasonably certain that the Russian would
rid himself of the baby as quickly as possible after having disposed of
Tarzan.

He and Mugambi now righted and launched the dugout, though it was a
most difficult feat in the face of the surf which rolled continuously
in upon the beach; but at last they were successful, and soon after
were paddling up the coast toward the mouth of the Ugambi. Here th
