"You can't beat that anywhere in the world," said Dunk, proudly.

"I almost feel as though she were alive," commented Herb.

"I must say you did a mighty fine job, boys," said Hawke, "and if she flies as well as she looks, we'll put in our application for medals."

"Is there any chance that she won't fly?" asked Fly anxiously.

"You never know what a brand new plane is going to do," responded Hawke, "and you're never sure till you're gliding safely up in the air, whether or not all the cogs are in tight. But I don't think there's much danger that this one won't fly."

"We'll steer straight for that old tower," said Jerry, "and see if we can't roust out the Thunder Bird—or devil bird, whatever it is."

"Better watch for it some dark night near the sheep fold," suggested Herb. "It's about due to be around here now. We haven't seen it for some time. But another rancher several miles north of father says he's had some sheep hurt and taken, so I suppose it's shifted its hunting ground for a while."

"Gee, I'm awful anxious to find out just what it is anyway," exclaimed Fred. "Certainly is a mysterious animal."

"Have you seen that old Indian snooping around here?" inquired Herb, changing the subject. "I saw him a minute or two ago peeping in through the door over there, but I didn't say anything at the time."

"Oh, I suppose he has some superstitious idea that this is a destroying evil spirit we're building," said Carl. "Only I wish he would keep away. The way he stands around and peers makes me nervous."
