"Put her out of her misery," said Nat, as Ding-dong, having regained his feet, darted at the top of his speed for the mouth of the cave.

Once more the rifles blazed away at the two green points of fire which marked the wounded cougar's eyes. This time dead silence followed the reports, which reverberated deafeningly in the confines of the cave. There was no doubt but that the animal was dead. But where was Ding-dong?

His companion Motor Rangers looked anxiously about them, but could see nothing of him. In the excitement they had not noticed him dart by. Presently, however, a slight noise near the cave month attracted their attention. There was Ding-dong out in the rain, and drenched to the skin, peering into the cave.

"C-a-can I c-c-c-come in?" he asked hesitatingly.

"Yes, and hurry up, too," ordered Nat in as stern a voice as he could command. "Your first duty," he went on, "will be to dig down in the clothes chest and put on dry things. Then you will refill the lamps with carbide, which you ought to have done two days ago, and after that you may patch up the tear the wind made in our shelter hood."

"And—phwit—after that?" inquired Ding-dong with so serious an aspect that they had to laugh.

"I'll think up something to keep you out of mischief," said Nat finally.

While Ding-dong set about his tasks after investing himself in dry clothes, the others skinned the cougar and kindled a fire with some driftwood that lay about the cave. Hot coffee was then brewed, and some of the stores opened. After imbibing several cups of the steaming mixture, and eating numerous slices of bread and butter, the Motor Rangers felt better.

By this time, too, the storm had almost passed over, only a slight drizzle remaining to tell of the visit of the mountain tempest. An investigation of the cave failed to show any trace of a regular den in it, and the boys came to the conclusion, which was probably correct, that the cougars had merely taken to it for shelter from the storm. However that was, all three of them felt that they had had a mighty narrow escape. Ding-dong inwardly resolved that from that time on he would take care to have the lamps packed with carbide, for Nat's relation of how nearly the sudden cessation of the light had cost him his life gave the stuttering youth many qualms.

"I guess the storm is about over," said Joe, looking out of the cave while holding a tin cup of coffee in his hand.
