"No, we don't have to do that," said Matt. "I know right where the machine is, and a light might give us away. You stand in the door, Carl, and I'll put the letter where I found it and be with you again in a brace of shakes."

"Vell, hurry oop. Oof Domlinson vas to come vile ve vas here, den ve vould be der vones vat got fooled."

Matt, with the location of the Red Flier firmly fixed in his mind, groped his way through the gloom and came to the front of the machine. With one hand sliding over the bonnet, he reached the side of the car, opened the tonneau door and stepped to the foot-board.

Just at that moment, while he was bending over with the letter in his hand, a pencil of light leaped suddenly out of the gloom and rested full on him.

Straightening up suddenly, he whirled his face into the light.

For an instant his eyes were blinded, and he could see nothing.

"Quick!" he heard a husky voice mutter from somewhere in the darkness. "Down him and grab that letter!" The next instant a fist leaped out of the gloom and into the ray of light. Matt dropped downward, falling off the foot-board.

The fist hit him a glancing blow on the shoulder, and he toppled backward. At the same moment the letter was snatched out of his hand.

"Py shinks," came the voice of Carl, "vat vas going on, anyvay? Who you fellers vas? Keep avay from me, or——"

Running feet had sounded along the barn floor. While Carl was talking, some one ran into him and knocked him flat with a quick blow.
