Through Matt's intrepid work, Tsan Ti had recovered the stolen ruby, but, as in the case where he had lost the counterfeit gem, Matt's success had been merely a fortunate blunder. On the other side of the account, Grattan could be charged with a theft of the two motor cycles and with sundry other sharp practices which had gone too much "against the grain" for Matt to overlook. The daring theft of the automobile from the garage pointed the way not only for Matt to help Martin recover the machine, but perhaps, also, to recover the motor cycles, to worst Grattan, and to be of some assistance to Tsan Ti.

On the way to the garage with Martin, Matt explained these matters to McGlory.

With the whistle of the New York boat still sounding in his ears, the cowboy listened to his chum, at first, with intense disapproval; but, at the back of McGlory's nature, there was as intense a dislike for being worsted by such a crook as Grattan as there was at the back of Matt's.

Cleverly the king of the motor boys harped on this chord, and aroused in his chum a wild desire to do something that would curb, finally and effectually, the audacious lawlessness of Philo Grattan. To such an extent did Matt influence McGlory that the latter began to wonder how he could ever have thought of leaving the Catskills while Grattan was at large.

"Sufferin' justice!" exclaimed the cowboy. "Grattan is trying to bluff us out of helping the mandarin. That's as plain as the pay streak in a bonanza mine. He must have been with Bunce when the bubble was lifted, and if we chase the chug cart we can hand the boss tinhorn a black eye by getting back the machine and landing the thieves in the skookum house. Say, that would be nuts for me! The mandarin and his idol's eye can go hang—it's Grattan we're after this trip."

Matt left his chum with that impression, well knowing that if Grattan could be captured, the affairs of the mandarin would adjust themselves satisfactorily.

The night man at the garage, his head bandaged, was lingering in the big room, watching one of the day men give a final wipe to the lamps of a six-cylinder flyer that was to take the trail after Grattan. The night man's face flushed joyfully when he saw Matt and McGlory.

"Good!" he exclaimed. "I guess there'll be something doing in these parts, now that Motor Matt is going to help in the chase."

"You're the man who was on duty when the automobile was stolen?" inquired Matt.

"Don't I look the part?"
