Hal, catching their movements out of the corner of his eye, veered the course of the airplane sharply. Prompt though he was, he had not acted promptly enough.

A hail of bullets sang above and on both sides of him. The plane fluttered like a big bird, wounded.

Hal's heart sank within him.

"Something wrong," he told himself grimly. "We're hit."

Chester also was alarmed. His fear grew as the airplane began to descend.

"What's the matter, Hal?" he called.

"Don't know," was Hal's reply. "I'm going to land and find out."

CHAPTER XXV

A BATTLE

The descending airplane became the target at which a hundred or more rifles were aimed. Nevertheless, it reached the ground without any of its occupants being wounded.
