The next instant they were in it, the water coming up to the hubs. Clouds of white steam arose about the car and a great sound of hissing filled the air as the burning portion encountered the chill of the water.

"Wall, that beats a fire department," exclaimed Cal, as, after remaining immersed for a short time, Nat drove the car up the opposite bank which, luckily, had a gentle slope.

As Cal had remarked, it did indeed beat a fire department, for the water had put out the flames effectually. An investigation showed that beyond having charred and blistered the woodwork and paint that the fire had fortunately done no damage. It would take some little time to set things to rights, though, after the ordeal they had all gone through, and so it was decided that they would camp for a time at the edge of the river.

"Hullo, what's all that going on over there?" wondered Joe, as he pointed to a cloud of dust in the distance.

Cal rapidly shinned up a tree, and shading his eyes with his hand, gazed for some moments in the direction of the cloud.

"Sheep!" he announced as he slid down again, "consarn thet Jeb Scantling, now I know who set thet fire."

The boys looked puzzled till Cal went on to explain.

"You know I told you fellows that cattlemen was dead sore at sheepmen," he said, "and that's the reason."

He jerked one brown thumb backward to indicate that "that" was the fire.

"Do you mean to say that Jeb Scantling started it?" gasped Nat. The idea was a new one to him.
