The Scaritts lived the other side of the tracks.  If you know Chippewa, or its equivalent, you get the significance of that.  Nobodys.  Not only did they live the other side of the tracks; they lived so close to them that the rush and rumble of the passing trains shook the two-story frame cottage and rattled the crockery on the pantry shelves.  The first intelligible sound the boy made was a chesty chug-chug-chug in imitation of a panting engine tugging its freight load up the incline toward the Junction.  When Chug ran away—­which was on an average of twice daily—­he was invariably to be found at the switchman’s shanty or roaming about the freight yards.  It got so that Stumpy Gans, the one-legged switchman, would hoist a signal to let Mrs. Scaritt know that Chug was safe.

He took his first mechanical toy apart, piece by piece.  “Wait till your pa comes home!” his mother had said, with terrible significance.  Chug, deep in the toy’s wreckage, seemed undismayed, so Mrs. Scaritt gave him a light promissory slap and went on about her housework.  That night, before supper, Len Scaritt addressed his son with a sternness quite at variance with his easy-going nature.

“Come here to me!  Now, then, what’s this about your smashing up good toys?  Huh?  Whatdya mean!  Christmas not two days back and here you go smashing—­”

The culprit trotted over to a corner and returned with the red-painted tin thing in his hand.  It was as good as new.  There may even have been some barely noticeable improvement in its locomotive powers.  Chug had merely taken it apart in order to put it together again, and he had been too absorbed to pause long enough to tell his mother so.  After that, nothing that bore wheels, internally or externally, was safe from his investigating fingers.

It was his first velocipede that really gave him his name.  As he rode up and down, his short legs working like piston-rods gone mad, pedestrians would scatter in terror.  His onrush was as relentless as that of an engine on a track, and his hoarse, “Chug-chug!  Da-r-r-n-ng!  Da-r-r-n-ng!” as he bore down upon a passerby caused that one to sidestep precipitously into the gutter (and none too soon).

Chug earned his first real bicycle carrying a paper route for the Chippewa Eagle.  It took him two years.  By the time he had acquired it he knew so much about bicycles, from ball-bearings to handle-bars, that its possession roused very little thrill in him.  It was as when a lover has had to wait over-long for his bride.  As Chug whizzed about Chippewa’s streets, ringing an unnecessarily insistent bell, you sensed that a motorcycle was already looming large in his mechanism-loving mind.  By the time he was seventeen Chug’s motorcycle was spitting its way venomously down Elm Street.  And the sequence of the seasons was not more inevitable than that an automobile should follow the motorcycle.  True, he practically built it himself, out of what appeared to be an old wash-boiler, some wire, and an engine made up of parts that embraced every known car from Ford to Fiat.  He painted it an undeniable red, hooded it like a demon racer, and shifted to first.  The thing went.
