the realms of possibility, for she knew well the
prowess of the beastlike man with whom it fought. There were not many
of them in Pal-ul-don, but what few there were were a terror to the
women of the Waz-don and the Ho-don, for the old Tor-o-don bulls roamed
the mountains and the valleys of Pal-ul-don between rutting seasons and
woe betide the women who fell in their paths.

With his tail the Tor-o-don sought one of Tarzan's ankles, and finding
it, tripped him. The two fell heavily, but so agile was the ape-man and
so quick his powerful muscles that even in falling he twisted the beast
beneath him, so that Tarzan fell on top and now the tail that had
tripped him sought his throat as had the tail of In-tan, the
Kor-ul-lul. In the effort of turning his antagonist's body during the
fall Tarzan had had to relinquish his knife that he might seize the
shaggy body with both hands and now the weapon lay out of reach at the
very edge of the recess. Both hands were occupied for the moment in
fending off the clutching fingers that sought to seize him and drag his
throat within reach of his foe's formidable fangs and now the tail was
seeking its deadly hold with a formidable persistence that would not be
denied.

Pan-at-lee hovered about, breathless, her dagger ready, but there was
no opening that did not also endanger Tarzan, so constantly were the
two duelists changing their positions. Tarzan felt the tail slowly but
surely insinuating itself about his neck though he had drawn his head
down between the muscles of his shoulders in an effort to protect this
vulnerable part. The battle seemed to be going against him for the
giant beast against which he strove would have been a fair match in
weight and strength for Bolgani, the gorilla. And knowing this he
suddenly exerted a single super-human effort, thrust far apart the
giant hands and with the swiftness of a striking snake buried his fangs
in the jugular of the Tor-o-don. At the same instant the creature's
tail coiled about his own throat and then commenced a battle royal of
turning and twisting bodies as each sought to dislodge the fatal hold
of the other, but the acts of the ape-man were guided by a human brain
and thus it was that the rolling bodies rolled in the direction that
Tarzan wished--toward the edge of the recess.

The choking tail had shut the air from his lungs, he knew that his
gasping lips were parted and his tongue protruding; and now his brain
reeled and his
