"Can't," she snapped back, "ain't such a thing as a saddle around here any more. But I'm a country girl, you know, and I can ride bareback all right. A halter's the only bridle I want, Frank. Give me the message, and I'll see that it gets to somebody in Bloomsbury."

"And here's some money, Sallie," the other went on.

"What! do you think—"

"There might be something to pay, you know, and we can't afford to take chances when there's so much at stake. Thank you a thousand times for helping us out, Sallie. Now, please get the horse. I'd like to see you started before we pull out, because we may have to chase after these fellows in our aeroplane, if they take a notion to fly away."

The girl hastened to lead the way into the stable where they did find an apology for a horse, which she immediately unhitched, and led outside.

"Hope she doesn't happen to run across that man on the way, because he might wonder what was taking her off like that, and do something to turn her back. What if he found your message on her, Frank?" and Andy, as he said this, turned an anxious gaze upon his cousin.

But Frank shook his head.

"I saw him dodge out of the lane and take to the woods," he remarked, "as though he knew of a short-cut across lots to the place where his friend and the biplane were hidden. No danger of his seeing Sallie, so don't mention it to her. Wait, I'll give you my hand to help you up, Sallie!"

But the country girl had led the horse alongside the drinking trough, and was on his back in a jiffy, long before Frank could come across.

"Goodbye, and good luck, boys!" she called back, as she gave the horse a switch with the end of the halter, and was off at a lumbering pace.
