“He is certainly eccentric in his appearance,” said Ralph. “I wonder who he can be.”

“No, what he can be,” corrected Clark, “for he’s an odd genius of some kind, I’ll wager.”

The object of their interest and curiosity had heard the derisive hail from across the street. He halted dead short, stared around him like a person abruptly aroused from a dream, traced the call to its source, thrust the device with which he had been experimenting into his pocket, and fixing his eyes on his mockers, started across the street. The hoodlum crowd nudged one another, blinked, winked, and looked as if expecting developments of some fun. The object of their derision looked them over in a calculating fashion.

“Did any one here speak to me?” he asked.

“No, Wheels—it was the birdies calling you!” hooted a jocose voice.

“You sort of suggest something, somehow,” drawled the lad in an abstracted, groping way. “Yes, certainly, let me see. What is it? Ah, perhaps I’ve made a memorandum of it.”

The lad poked into several vest pockets. Finally he unearthed a card which seemed to be all written over, and he ran his eye down this. The crowd chuckled at the profound solemnity of his manner. 45

“H’m,” observed the boy designated as “Wheels.” “Let me see. ‘Get shoes mended.’ No, that isn’t it. I have such a bad memory. ‘Order some insulated wire.’ No, that’s for an uptown call. ‘Buy Drummond on Superheated Steam.’ That’s for the bookstore. Ah, here we have it. ‘Kick Jim Scroggins.’ Who’s Jim? Aha! you young villain, I remember you well enough now,” and with an activity which could scarcely be anticipated from so easy-going an individual, Wheels made a dive for a big hulking fellow on the edge of the crowd. He chased him a few feet, and planted a kick that lifted the yelling hoodlum a foot from the ground. Then, calmly taking out a pencil, he crossed off the memorandum—“Kick Jim Scroggins”—gave the crowd a warning glance, and proceeded coolly down the sidewalk, resuming his occupation with the contrivance he had placed in his pocket.

The gang of loafers had drawn back. A sight of the massive arms and sledge hammer fists of the young giant they had derided, and his prompt measures with one of their cronies, dissuaded them from any warlike move.

“Whoop!” commented Clark in an exultant undertone, and he fairly leaned against his companion in a paroxysm of uncontrollable laughter. “Quick, nifty and entertaining, that! Say Engineer 46 Fairbanks, I don’t know who that fellow Wheels is, but I’d be interested and proud to make his acquaintance. Now steam up and air brake ready, while we pass the crossing!”
