As he took his hands from the wheel, Tippoo leaned sideways and gripped the rim. For an instant Matt was poised on the foot-board, steadying himself by holding to the seat. A moment more and he had thrown himself across the gap between the two cars.

It was his second daring leap for that day, but this jump was more dangerous than the other one, for, if he had slipped, he would have had two cars to reckon with, instead of one. Both cars were racing furiously, and the Red Flier, with no hand to hold it, was taking all inequalities of the road and plunging and swaying as it rushed onward.

But Motor Matt never put his mind to anything that he did not accomplish. Ferral drew back in the seat to give him every chance, and Matt sprawled with a jar that made the car shiver from crank to tail light.

Whether he was hurt or not did not appear. In a flash he was up, cutting off the power and bearing down on the emergency-brake.

It was a stop such as Matt hated to make, for fear of wrenching the machinery, but it was either that or go over into the chasm. As it was, the Red Flier ran across the curve and quivered to a halt, with the front wheels on the very brink. Matt and Ferral, from their seats, could look over the hood and down into the dizzy, swirling depths below.

Ferral's face was white as death, and he relaxed backward, limp and gasping. Matt backed the Flier away, and turned around, then drew his knife from his pocket and cut the ropes that bound Ferral.

"Who did this, Dick?" he asked huskily.

"Two of my cousin's friends," replied Ferral, drawing his hands around in front of him and rubbing his chafed wrists. "Toss us your fin! What you've done this day, messmate, Dick Ferral will never forget."

A shiver ran through him as he gripped Matt's hand.

"The murderous scoundrels!" muttered Matt, his eyes flashing.
