“Here we go!” he cried. “Look out everybody!”

Slowly at first, but gathering speed, the auto moved out of the cave. The lamps lighted up the path, and, though the boys realized that the lanterns disclosed their position to their enemies, they had to use them for their own safety. It was too dark to do without them.

A few seconds later and the car emerged from the cavern. As it shot out there came a chorus of angry cries from the camp of the ranchmen, and several shots were fired, though none of them came close enough to be uncomfortable.

“Here we go!” cried Jerry again, as he increased the speed, and the auto fairly leaped forward. It swayed from side to side, and struck several ruts, so that the occupants were tossed about.

But the main thing was that they went ahead, and away from their enemies. Jerry, peering as best he could into the darkness ahead, made a course for the stream, intending to go close to it, and then run along the bank, or near it, as he had noted in the afternoon that there was a fairly good road there.

Gradually the shouts of the men, and the firing of their guns died away, and the travelers began to breathe more freely. They had made their escape, and, for the present, were safe.

“Oh do let’s stop and get a drink!” pleaded Bob.

“Not yet!” exclaimed Jerry. “Five minutes more will not kill you, and it may save all our lives,” for he did not want to slack up while there was any danger of the ranchmen coming after them.

The five minutes seemed like an hour to Bob, and the others, too, were impatient. But at last Jerry shut off the power and the machine came to a halt not far from the creek. Out scrambled the boys and the professor, and then, in spite of the danger of drinking snakes and lizards in the darkness, they all made for the stream, where they quenched their thirst from small collapsable cups which each one had been holding in readiness for just that chance.

“That’s better than an ice cream soda!” exclaimed Ned.
