"There you are," said he. "If Matt hears anything about Brady, or the rest of his gang, tell him to be sure and let me know."

"He vill do dot, you bed you. He iss as anxious to haf Brady captured as anypody."

"He ought to be. Brady will do everything he can to get even with Matt for the havoc Matt has played with the gang. And that's what leads me to believe Matt may see something of him. Tell your friend that——"

But Carl waited for no more. He had already lost more time than he could well afford.

Bolting out of the chief's office, he made a rush for the hotel. There he secured his satchel and started along the road toward the rolling mills.

The drops rolled off Carl's face as he hurried. As soon as he struck the beginning of the road that ran past the swampy meadow, he kept his eyes in the direction of the balloon house. It was several minutes before he sighted the big building, and then it was far off and could be seen only indistinctly.

Swiftly he drew nearer and nearer. As the building came more prominently into view, he was able to make out the air ship, swaying in front.

"Dey haf got der Hawk oudt oof der house!" he muttered. "Dey're alretty to go, und dey vas only vaiting for me."

Even as Carl was congratulating himself on the fact that he was not going to be left behind, he was astounded to see the Hawk move upward and away from the balloon house. He was still so far away that he could not see those in the car, and a terrific fear shivered along his nerves.

"Himmelblitzen!" he groaned, "I vouldn't haf t'ought it bossiple! Dey vas leafing me in der lurch. Modor Matt, der pest friendt vat I efer hat, iss skyhooting avay mitoudt his Dutch bard! Vat iss der meaning oof dot?"
