"Share and share alike with the rest of us," averred Matt. "That Chinese boy is loyalty itself. Down in that shelter tent, below the post trader's, he spends his nights and days watching the aëroplane."

"And talking to it, and singing about it, and burning rice-paper prayers to the heathen josses, asking them to keep it carefully and not let it go broke while up in the air," put in McGlory. "Oh, he's a freak, that Ping boy; but, as Matt says, he's a mighty good sort of a freak at that. Look how he ran off with the rifles when we fooled the Tin Cup punchers on the hill! And remember how he slammed that stone through the window when Murgatroyd had drawn a fine bead on me and was about to press the trigger. Share and share alike? Well, I should say."

"You're still determined to go into the show business, Matt?" asked Cameron anxiously.

"I don't see why we shouldn't," said Matt. "Five hundred a week isn't to be sneezed at. Joe's agreed, and so has Ping. When the first favorable day arrives, we're going to fly to Fargo."

Two days later the favorable moment was at hand. All the soldiers at the post were out to witness the start, and even the gruff post trader was present to say good-by to the king of the motor boys and his friends.

Matt's last call, at the post, was made on Prebbles. The old man was practically out of danger, but his recovery would take time, and for a long while yet he would have to remain in bed.

He was not able to say much, but what little he did say Matt considered an ample reward for the strenuous adventures that had befallen him and his chums on their flight to the upper Missouri.

Newt had become his sworn friend. Whenever Matt wanted any help, in any way that was within Newt's power to grant, he was surely to call on young Prebbles.

When finally Motor Matt took his way down the post hill for the last time, he was in an exceedingly thoughtful mood.

He remembered when he had first come to Devil's Lake, knowing nothing about aëroplanes, and had practiced with the June Bug until he had acquired the knack of flying the machine and had made good and sold the machine to the government for enough to give large profit to himself and his friends, and, what pleased him most, to place Mrs. Traquair above want.
