It was just that hour between twilight and darkness when shapes can still be distinguished moving about that Billy chanced to look up in the big tree that stood near the fence of the goat yard. He thought he saw two yellow balls of fire about the size of big marbles shining up among the leaves in the tree. As he looked, they seemed to move slowly toward him. Then looking more closely, he made out the outline of a big panther crouching on the limb ready to spring down on the unsuspecting Angoras peacefully sleeping directly under the limb the beast was on.

Billy gave the alarm, but too late. The panther had made a spring and landed on the back of a young Angora goat and was now devouring it greedily, while all the rest of the goats ran over to where Billy and his family stood in an opposite corner of the yard.

"All of you big goats with horns get ready to fight," commanded Billy, "for the minute that panther has devoured that victim, he will come over here for another nice young, juicy goat."

"Oh, my darlings! He will pick them out," wailed Daisy, "because they are the very youngest and will make the most tender eating."

"Don't cry, Daisy. He hasn't gotten them yet, and he won't while I am alive," said Billy Whiskers.

"Nor while I breathe either!" exclaimed Billy Junior, not to be outdone.

When the panther had finished his meal, he stood up, looked around, licked his chops, switched his tail, and called for his mate to come and join him in the feast. But that call was his undoing. His mate could not get out of her cage, but the panther's keeper recognized his voice and hastily calling some men and guards, he started to find the panther by going in the direction of the call. As the moon had come up in full glory, they had no trouble in locating him.

They found him none too soon, for just as they appeared at the fence, the panther started toward the goats to select another victim. He had his eye on one of the Twins, that Billy Whiskers could see. Brave as could be, Billy walked out of the herd and straight at the panther, intending to try to drive him away at least, but he knew it would be almost impossible as these beasts are strong, as quick as a cat and are bloodthirsty fighters.
