Jeb put his bag down quickly and pulled his jacket open with both hands, himself look big to the cougar. Itworked. 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, 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.
