Tarzan on Mars
"I see it," said Carter. "But do you also discern the fact
that it is a gate in an outer wall? The top of the wall must be
a full hundred ads high."
Tarzan scanned the wall. "It is not a wall," he answered.
"But a dam—or dike. Evidently the water level here is
variable at times."
The two men advanced along the rocky ledge toward the
Escarpment. As they did so, they found that the ledge broadened
out into a wide, barren shore which was more than a
mile in length and half a mile deep. The great wall stood at
the farther end. They walked rapidly toward it. When they
arrived they found that there was no apparent means of
opening the great door from their side.
"It is unfortunate that the wall is so high," observed John
Carter. He knew that had it been only half as high, he might
have attempted to scale it, but this lofty barrier was too much
even for his earthly strength.
"Look out!" cried Tarzan. At the same time he pulled the
Warlord with him behind a large overhanging rock just as an
explosion shattered the ground where they had been standing.
"There are sentinels on the wall!"
"Ah!" said the Warlord. "Then that means they are
guarding a possible entrance to the fortress from its base! We
must get over the top of that barrier!"
"Here comes a possible answer," replied the apeman,
pointing upward. As John Carter followed his pointing finger
with his eyes, he discerned half a dozen malagors descending
rapidly toward them. On their backs he could make out the
figures of his own commandos. Quickly, he signalled to them
and they darted in swiftly under the protecting rock, barely
escaping the radium rifle fire of the sentinels above.
"Sire!" cried the leading commando. "We thought you had
perished in the lake!"
"Quickly!" exclaimed the Warlord. "Did you see any of
the others enter Zumor?"
