Straight and true it sped to its mark.
And it struck home none too quick. The lion had already crouched for a spring on the defenseless lads, who stood between himself and his mate, when Nat's missile was discharged.
Crack!
The sharp noise of the stone's impact with the skull of the crouching feline sounded like a rifle shot.
"Bull's-eye!" yelled Joe excitedly.
And bull's-eye it was. The rock had a sharp edge which Nat, in his haste, had not noticed. As it struck the lion's head it did so with the keen surface foremost. Like a knife it drove its way into the skull and the lion, with a howl of pain and fury, turned, stumbled forward a few paces, and then rolled over.
Before the others could stop him, Ding-dong Bell, entirely forgetting the other lion, dashed forward to examine the fallen monster. The result of his action was that his career came very near being terminated then and there. The cougar had only been stunned, and as the stuttering boy gave one of its ears a tug, it leaped erect once more and struck a blow at him with its chisel-like claws that would have torn him badly had they struck.
But Ding-dong, though deliberate in his speech, was quick in action. He leaped backward like an acrobat, as he saw the mighty muscles tauten for action, and so escaped being felled by the blow. He could feel it "swish" past his nose, however, and entirely too close to be pleasant.
In the meantime, Nat, realizing that his best move would be to get to their arms, had made a flying leap for the auto and seized an automatic rifle of heavy calibre. As Ding-dong leaped back he aimed and fired, but in the darkness he missed, and with a mighty bound the wounded cougar leaped out of the cave and dashed off through the storm into the brush on the hillside above.
"One!" exclaimed Nat, like Monte Cristo in the play.
