Before he or Nat could descend, the driver did so. He thrust the reins into the hands of old John Dempsey, and went over the wheel in a flash. Smiling and bowing he put out his hand for the basket, and turned swiftly to hand it up before aiding the old lady herself.

It was at this very moment that the sensitive Ophelia decided to make a break for liberty. She squawked, pushed up one of the basket lids, and flopped right out over the Mexican’s head.

“Oh! stop her!” cried Mrs. Petterby.

But there was no stopping Ophelia just then. She struck the nearest mustang and he plunged ahead, snorting. On the instant all four of the beasts were off at a gallop, leaving the Mexican, Mrs. Petterby, and Ophelia herself, behind.


CHAPTER XIII
AT THE RANCH HOUSE

“I thought I was in an airship!” Tavia declared.

That was after the excitement was all over, however. At the moment the mustangs started, all she did was to scream!

The four half-wild little beasts leaped forward with one accord when the frightened pullet flew squawking over them. The coach lurched horribly; but the wheels remained in the ruts.

Old John Dempsey held the ribbons, and held them firmly; but he was not on the driver’s side of the seat. There was both a foot-break and a half-lever-break; but he was unable to reach either. And in his old arms was no longer the strength to pull the beasts in.
