Laddie had thought up a new riddle—and it was a good one. He knew it was good and he told everybody about it, he was so excited.

"Listen!" he cried, when he half tumbled out of his saddle by the steps of the veranda. "This is a good riddle. Listen!"

"We're listening, Son," said Cowboy Jack. "Shoot!"

"What is it," asked Laddie earnestly, "that looks like a horse, has four legs like a horse, runs like a horse, eats like a horse, but it isn't a horse?"

"A cow," said his twin promptly.

"No, no! A cow has horns. A horse doesn't," Laddie declared scornfully.

"A colt," guessed Russ.

"No, no!" rejoined the eager Laddie. "A colt is a little horse, so that could not be the answer, Russ Bunker."

"A giraffe," suggested Vi again.

"I wish you wouldn't, Vi," complained the riddle-maker. "Does a giraffe look like any horse you ever saw?"
