Dodge, throbbing uneasily, reined in hard.

His horse began to chafe as it found itself forced back.

In another moment Dodge was lagging behind.
"Keep the pace, Mr.Dodge! Keep the pace, sir!" called out Captain Hall.
Bert obeyed, but in fear.

He did not know at what instant this uneasy animal would rear and unhorse him.
At last the detachment was halted and the line faced about.

Now the detachment rode in reverse direction around the tan-bark.
By this means Dodge became the leader.
Through the walk and the trot, he managed to get along all right, though he was nervous.
"Stick to your saddle, Mr.Dodge!" called Captain Hall.
