"What is it?" they asked simultaneously.

"Horn-toad," Bronco replied. "Caught him this mornin' and I was pretty sure you hadn't seen one, so I kept him."

"Won't he bite?" Jamie's tones were doubtful.

"Not on your life," answered the cowboy.

They regarded the little creature as Bronco put it on the ground and dragged a bit of string from his pocket. He tied this about the toad's hind legs close to the body.

"Look at him," was the command, as Bronco slid his finger over the rough, tiny-horned back from tail to head.

With a wild scurry of legs, the toad raced to the end of the string and struggled to escape; but, Bronco's finger touched its head and moved gently toward the jerking tail. The toad's eyes closed, his head drooped toward the ground, the legs and tail became motionless. Jamie gave a little squeal of delight, and cried, "He's gone to sleep!"

"Hang onto the string a minit."

Jamie clutched it, while Bronco held a consultation with the cook at the tail-board of the chuck-wagon. Soon he returned with a small, empty match-box.

"This'll make a fine wagon," he announced, tying the match-box to the end of the string. "Now, thar we are! All you gotter do to make him move lively is run your finger 'long his back like I done, and contrarywise, from his head to his tail, if you want him to stop. When I was a kid in Texas, me an' my little brother uster catch 'em and have races this way."
