"You act like that thing was full of gold bricks," remarked McGlory, as he and Matt climbed the stairs to their room as soon as the meal was done.

"Not gold bricks," said Matt. "There's the biggest little thing in this grip, Joe, you ever saw in your life."

"Have you hired out to that Murgatroyd person as the human sky-rocket?" inquired McGlory, as he unlocked and opened the door of the room.

"I'm going to try out an aëroplane, up at Fort Totten, but not for Murgatroyd. A lot of things came up this morning, and that's what took me so long. The only way for you to get the whole business straight is for me to begin at the beginning. Now sit down, take it easy, and I'll tell you what I've found out, and what I've done."

The cowboy was anxious to see what was in the satchel, but Matt made no move to gratify his curiosity, just then; instead, he launched into his experiences at Murgatroyd's office, at City Park, and, lastly, at Mrs. Traquair's. When he was through, McGlory rubbed his eyes, stared, then rubbed his eyes and stared again.

"What's the matter with you?" inquired Matt.

"Dreamin'," answered the cowboy. "You're going to take a little fly for fame and fortune, and I'm in on the deal to the tune of two hundred and fifty cold plunks. It's all right, pard. I'd buy an interest in the North Pole if you thought there was any profit in icicles; but tell me: Will it be pleasant for your Uncle Joe to stand on the ground and watch you taking flyers in a thing that killed one fellow, and is hungry to wipe out another? Remember, I'm putting up two-fifty for the privilege. It's all very fine to help out a poor widow in distress, and to backcap a loan shark like Murgatroyd—that reads like a book, and I'm plumb tickled to help—but, son, there's your neck to think about."

"I'm not going to take any foolish chances, Joe," said Matt earnestly. "I'm hungry to run an aëroplane with a gas engine—and this aëroplane is the goods, don't forget that."

"Um-m! Suppose you let me look at the goods?"

Matt unbuckled the straps, and lifted the model of the aëroplane out of its case.
