"Great!" shouted the cowboy. "I haven't the least fear that we're going to drop, and I'd just as lieve go out on the end of one of the wings and stand on my head."

"Don't do it," laughed Matt, keeping his eyes straight ahead, while his hand trawled constantly back and forth with the lever controlling the wing ends.

"Him plenty fine!" cooed Ping.

"Fine ain't the name for it," said McGlory. "I'm so plumb tickled I can't sit still. And to think that I shied and side-stepped, when I might have been having this fun right along! Well, we can't be so wise all the time as we are just some of the time, and that's a fact. How far do you make it, Matt, to where we're going?"

"A little over a hundred miles, as the crow flies."

"As the Comet flies, you mean. How fast are we going?"

"Fifty miles an hour."

"That clip will drop us near Burnt Creek in two hours. Whoop-ya!"
