[CHAPTER XXV.]
AN UNEXPECTED FRIEND.

It was too uneven a chase to last long. Bob soon found that his enemies were gaining on him, and he resolved to play a trick. He came to a big rock and dropped down behind it, hiding in the shadow.

For a time the Mexicans were baffled, but they spread about in a half circle and Bob could hear them gradually surrounding him. Still he hoped to escape detection.

“Can’t you find him?” he heard Noddy call.

“He seems to have given us the slip,” replied Vasco. “But we’ll get him yet.”

Noddy sent the searchlight of the automobile all about the rock behind which Bob was hidden, but the deep shadow cast protected the boy.

At length, however, one of the Mexicans approached the place. At the same instant Bob was seized with an uncontrollable desire to sneeze. His nose tickled and, though he held his breath and did everything he had ever read about calculated to prevent sneezes, the tickling increased. Finally he gave voice to a loud “Ka-choo!”

Diablo!” exclaimed the nearest Mexican. “What have we here?”

He was at the rock in an instant and lost no time in grabbing Bob. The boy tried to struggle and escape again, but his captor held him in a firm grip. The Mexican set up a shout at the discovery of his prize, which speedily brought Vasco and his comrades to the scene.
