It is not the least unlike, in motive and execution, the practice of country boys who go forth in squads to set traps for rabbits or to round up a coon.
It is characterized by a pure spirit for adventure, and the vicious training really begins when they are arrested, or when an older boy undertakes to guide them into further excitements.

From the very beginning the most enticing and exciting experiences which they have seen have been connected with crime.

The policeman embodies all the majesty of successful law and established government in his brass buttons and dazzlingly equipped patrol wagon.
The boy who has been arrested comes back more or less a hero with a tale to tell of the interior recesses of the mysterious police station.

The earliest public excitement the child remembers is divided between the rattling fire engines, "the time there was a fire in the next block," and all the tense interest of the patrol wagon "the time the drunkest lady in our street was arrested." In the first year of their settlement the Hull-House residents took fifty kindergarten children to Lincoln Park, only to be grieved by their apathetic interest in trees and flowers.

As they came back with an omnibus full of tired and sleepy children, they were surprised to find them galvanized into sudden life because a patrol wagon rattled by.
Their eager little heads popped out of the windows full of questioning: "Was it a man or a woman ?" "How many policemen inside ?" and eager little tongues began to tell experiences of arrests which baby eyes had witnessed.
The excitement of a chase, the chances of competition, and the love of a fight are all centred in the outward display of crime.
