Now, Johnnie Green was spry; but this black lamb was sprier. Whenever Johnnie thought he had the lamb the black rascal always managed to slip out of his clutches.

"I'll help you," said Farmer Green. And climbing the fence, he soon had the lively lamb cornered and caught.

Then Johnnie lost no time in taking his new pet in his own arms.

"I'm going to call him——" Johnnie began, as his father let go of the struggling black armful.

But Johnnie Green never finished what he had started to say. The first thing he knew the lamb had squirmed out of his arms and was running up the lane.

Johnnie straightened up and gazed after him in dismay.

"I don't believe I'll call him anything," he murmured, half to himself.

Farmer Green couldn't help laughing. And then, noticing a very disappointed look on Johnnie's face, he said, "Cheer up, Johnnie! That lamb is the youngest one on the farm, but he's too big for a pet. He's a wild one. Let him run with the flock and we'll see if we can't do something to make you feel happy."

Well, Johnnie Green knew that when his father talked like that it was silly to be glum. So he cried, "All right!" And turning his back upon the black lamb, which was by this time almost up to the head of the lane, Johnnie walked back to the woodshed.

The next day, when Farmer Green came home from a drive over the hill, Johnnie shouted "Hurrah!" once more. For lying on a bit of hay in the bottom of the buggy was a white lamb no more than half as big as the lively black scamp that had got away from Johnnie the day before.
