     Lying in the sun on a rock, the cougar (美洲豹) saw Jeb and his son. Tom before they saw it. Jeb put

his bag down quickly and pulled his jacket open with both hands, making himself look big to the cougar. It

worked. The cougar hesitated, ready to attack Jeb, but ready to forget the whole thing, too.

     Jeb let go of his jacket, grasped Tom and held him across his body, making a cross. Now the cougar's

enemy looked even bigger, and it rose up, ready to move away, but unfortunately Tom got scared and

struggled free of Jeb.

     "Tom, go" shouted his father.

     But Tom broke and ran and that's the last thing you do with a cougar. The second Tom broke free, Jeb

threw himself on the cougar, just as it jumped from the rock. They hit each other in mid-air and both fell.

The cougar was on Jeb in a flash, forgetting about Tom, which was what Jeb wanted.

     Cougars are not as big as most people think and a determined man stands a chance, even with just his

fists. As the cougar's claws (爪子) got into his left shoulder, Jeb swung his fist at its eyes and hit hard. The

animal howled (吼叫) and put its head back. Jeb followed up with his other fist. Then out of the corner of

his eye. Jeb saw Tom. The boy was running back to help his father.

     "Knife, Tom," shouted Jeb.

     The boy ran to his father's bag, while Jeb started shouting as well as hitting, to keep the cougar's attention

away from Tom. Tom got the knife and ran over to Jeb. The cougar was moving its head in and out, trying

to find a way through the wall Jeb was making out of his arms. Tom swung with the knife, into the cougar's

back. It howled horribly and ran off into the mountains.
