moving about upon the floor.

Four steps at a time John Clayton took the stairs that led to the
floor above. His wife and the servant hurried after him. Once he
called his son's name in a loud voice; but receiving no reply he
launched his great weight, backed by all the undiminished power
of his giant muscles, against the heavy door. With a snapping of
iron butts and a splintering of wood the obstacle burst inward.

At its foot lay the body of the unconscious Mr. Moore, across whom
it fell with a resounding thud. Through the opening leaped Tarzan,
and a moment later the room was flooded with light from a dozen
electric bulbs.

It was several minutes before the tutor was discovered, so completely
had the door covered him; but finally he was dragged forth, his
gag and bonds cut away, and a liberal application of cold water
had hastened returning consciousness.

"Where is Jack?" was John Clayton's first question, and then;
"Who did this?" as the memory of Rokoff and the fear of a second
abduction seized him.

Slowly Mr. Moore staggered to his feet. His gaze wandered about
the room. Gradually he collected his scattered wits. The details
of his recent harrowing experience returned to him.

"I tender my resignation, sir, to take effect at once," were his
first words. "You do not need a tutor for your son--what he needs
is a wild animal trainer."
