panied them beyond the
limits of A-lur and after they had bid them good-bye and Tarzan had
invoked the blessings of God upon them the three Europeans saw their
simple, loyal friends prostrate in the dust behind them until the
cavalcade had wound out of the city and disappeared among the trees of
the nearby forest.

They rested for a day among the Kor-ul-ja while Jane investigated the
ancient caves of these strange people and then they moved on, avoiding
the rugged shoulder of Pastar-ul-ved and winding down the opposite
slope toward the great morass. They moved in comfort and in safety,
surrounded by their escort of Ho-don and Waz-don.

In the minds of many there was doubtless a question as to how the three
would cross the great morass but least of all was Tarzan worried by the
problem. In the course of his life he had been confronted by many
obstacles only to learn that he who will may always pass. In his mind
lurked an easy solution of the passage but it was one which depended
wholly upon chance.

It was the morning of the last day that, as they were breaking camp to
take up the march, a deep bellow thundered from a nearby grove. The
ape-man smiled. The chance had come. Fittingly then would the
Dor-ul-Otho and his mate and their son depart from unmapped Pal-ul-don.

He still carried the spear that Jane had made, which he had prized so
highly because it was her handiwork that he had caused a search to be
made for it through the temple in A-lur after his release, and it had
been found and brought to him. He had told her laughingly that it
should have the place of honor above their hearth as the ancient
flintlock of her Puritan grandsire had held a similar place of honor
above the fireplace of Professor Porter, her father.

At the sound of the bellowing the Ho-don warriors, some of whom had
accompanied Tarzan from Ja-don's camp to Ja-lur, looked questioningly
at the ape-man while Om-at's Waz-don looked for trees, since the gryf
was the one creature of Pal-ul-don which might not be safely
encountered even by a great multitude of warriors. Its tough, armored
hide was impregnable to their knife thrusts while their thrown clubs
rattled from it as futilely as if hurled at the rocky shoulder of
Pastar-ul-ved.

"Wait," said the ape-man, and with his spear in hand he advanced toward
the gryf, voicing the weird cry of the Tor-o-don. The bellowing ceased
and turned to low rumblings and presently the huge beast appeared. What
