beside the carriage.

"Look out for the horses," called Percy, as he drove the heels of
his heavy shoes into the moaning mass on the ground.

"Lie there, you brute," he cried, "don't you dare to move."

"I have the lines," said Adelaide hoarsely, "but can't I do
something more?"

"No. they're both down," he answered. "Wait a minute."

He found himself between the negroes lying with their faces to the
ground. Instantly he grasped each by the wrist and with an inward
twist he brought forth cried for mercy. It was a trick he had
learned in college, that, by drawing the arm behind the back and
twisting, a boy could control a strong man.

"Can't I help you?" Adelaide called again, and Percy saw that she
was out of the carriage and standing near.

"Will the horses stand?" he asked.

"Oh, yes, they're quiet now."

"Then take the tie rope and tie their feet together. Use the slip
knot just as you do for the hitching post," he directed. "If they
dare to move I can wrench their arms out in this position. Right
there at the ankles. Tie them tight and as closely together as you
can. Wrap it twice around if it's long enough."
