at he had been discovered he turned back as though to
relinquish his planned adventure.

"Where were you going?" panted the excited Mr. Moore.

"I am going to see Ajax," replied the boy, quietly.

"I am astonished," cried Mr. Moore; but a moment later he was
infinitely more astonished, for the boy, approaching close to him,
suddenly seized him about the waist, lifted him from his feet and threw
him face downward upon the bed, shoving his face deep into a soft
pillow.

"Be quiet," admonished the victor, "or I'll choke you."

Mr. Moore struggled; but his efforts were in vain. Whatever else
Tarzan of the Apes may or may not have handed down to his son he had at
least bequeathed him almost as marvelous a physique as he himself had
possessed at the same age. The tutor was as putty in the boy's hands.
Kneeling upon him, Jack tore strips from a sheet and bound the man's
hands behind his back. Then he rolled him over and stuffed a gag of the

of the down spout from an eaves trough.

Mr. Moore wriggled and struggled about the bed. He was sure that he
should suffocate unless aid came quickly. In his frenzy of terror he
managed to roll off the bed. The pain and shock of the fall jolted him
back to something like sane consideration of his plight. Where before
he had been unable to think intelligently because of the hysterical
fear that had claimed him he now lay quietly searching for some means
of escape from his dilemma. It finally occurred to him that the room
in which Lord and Lady Greystoke had been sitting when he left them was
directly beneath that in which he lay upon the floor. He knew that
some time had elapsed since he had come up stairs and that they might
be gone by this time, for it seemed to him that he had struggled about
the bed, in his efforts to free himself, for an eternity. But the best
that he could do was to attempt to attract a
