He was pursuing an electric car that ran at a high rate of speed, but the motor cycle must have been going five feet to the car's one. Before Matt fairly realized it he was within sight of the car.

When he was close enough to be heard he began to call to the conductor to stop. The passengers heard him, as the row of heads thrust out from each side of the car conclusively proved; and the conductor also heard him, for he appeared on the rear platform.

Matt could see the conductor reaching for the bell rope. At the same time, Wily Bill rushed out on the back platform, took in the situation at a startled glance, and then dropped dexterously from the car at the track side.

Matt was so wrapped up in what Wily Bill was doing that Ping's leap from the front platform escaped him entirely.

Wily Bill scurried for the side of the road, and Matt shut off the power and glided after him.

"Hold up there, Wily!" cried Matt.

The "barker" paid no attention, but plunged up the bank and darted off into the timber.

By that time Motor Matt's blood was up. He knew that a great deal depended on the capture of Wily. If the "barker" could be made to tell when and how he had received that note in Hindoostanee, a clue to the whereabouts of Ben Ali and the missing Margaret Manners would be secured.

Appreciating fully the exigencies of the case, Matt sprang from the wheel and leaped up the bank. From the top of the rise he could see nothing of Wily, but a crashing of the undergrowth told him plainly in which direction the man had gone. He was but an instant in taking after him.

Wily's actions were those of a guilty man; in fact, they inferred a deeper guilt than the mere possession of a note in Hindoostanee would indicate.
