Matt's heart went down into his shoes. He hadn't thought of that. Of course, Chub would be at the track! Chub was there to see Matt win the motor-cycle! Oh, the irony of fate!

Clipperton thrust his drawn face in at the door. His eyes glowed with a hope which was past his understanding.

Delray rattled the key and the flashes quivered back and forth between the balls, jumped off the lightning-rod tip at the top of the derrick and darted in every direction with the swiftness of thought.

Suddenly the sounder began to click. "What's this, what's this?" mumbled Delray, bending over the relay instrument and listening intently. Scarcely breathing, Matt and Clipperton kept their eyes on Delray's face. "Why, it's Susie McReady!" exclaimed Delray. "Matt King is missing—Chub and Perk at the park hunting for him—everybody in town hunting—Susie came back to the house to ask me to hunt—now, what do you think of that? Talk about luck! But what good is it going to do? That's what gets me."

"Tell Susie I'm here," said Matt; "tell her I was abducted from Phœnix last night to keep me out of the race; tell her to call up Major Woolford on the phone at the park; tell her to have the major lay quick hands on Ed Penny and send him along the Black Cañon road on the Comet as fast as he can come; have Susie tell the major to tell Penny that everything depends on the record he makes between Phœnix and the Bluebell, and that I'll walk along the Black Cañon road to meet him and save a little time. Shoot 'er through! Hustle, old chap."

"Oh, tell, tell, tell!" groaned Delray. "Why, you're talking like a house afire. Here goes."

Click, click, clickety-click, sang the key, the crackle of the spark keeping a merry accompaniment. Delray repeated the message. As he was finishing, Matt started for the door.

"Wait," called Delray, "here's an answer." The sounder began to click and then stopped dead. "No, there ain't," muttered Delray; "something's slipped a cog and the home-made machine is out of commission. Anyhow, Matt, she held together until we got your message through. Go it, and good luck to you!"

Matt was already through the door and striking a bee-line for the Black Cañon road, which ran past the derrick. Clipperton had caught his second wind and was following him.
