They came to closer quarters. The soldiers began to use their carbines for clubs, not taking the time to reload. Then they drew their sabres and charged the Mexicans under Vasco, who had drawn his force up in a hollow square. Several on both sides were killed in this mêlée.

The boys and the professor, who, under the captain’s later orders, had kept to the rear, now came dashing up in the automobile. Maximina was lying down on the floor of the tonneau, out of harm’s way.

Jerry was keeping an eye on Noddy and his auto, and he noticed that the machine, which, as he could see plainly now, held Bob, kept well behind the brigands.

“We must get Bob, no matter what happens,” said Jerry to Ned. “Look sharp now. I’m going to try something.”

“What is it?” asked Ned.

“Just you watch!” exclaimed Jerry. “Look out!”

He ducked, to avoid a bullet that sang over his head.

“What’s the use of doing that?” asked Ned. “The bullet is past when you hear it sing.”

“Can’t help it,” replied Jerry.
