The rear files of the horsemen, evidently intending to go to the other side of the camp, rode through the low bushes.

Four of them passed so near the boys that they caught in the moonlight a glimpse of the two stooping figures.
"Who is there?
Halt!" sharply cried one of them, an officer.
But St.Clair cried also: "Run, Harry! Run for your life, and keep to the bushes!" The two dashed at utmost speed down the strip of bushes and they heard the thunder of horses' hoofs in the open on either flank.

A half dozen shots were fired and the bullets cut leaves and twigs about them.
They heard the Northern men shouting: "Spies! Spies! After them! Seize them!" Harry in the moment of extreme danger retained his presence of mind: "To the cornfield, Arthur!" he cried to his comrade.

"The fence is staked and ridered, and their horses can't jump it.

If they stop to pull it down they will give us time to get away!" "Good plan!" returned St.Clair.
