_First forms of spontaneous social organizations.--_ Gulick has studied the propensity of boys from thirteen on to consort in gangs, do "dawsies" and stumps, get into scrapes together, and fight and suffer for one another. The manners and customs of the gang are to build shanties or "hunkies," hunt with sling shots, build fires before huts in the woods, cook their squirrels and other game, play Indian, build tree-platforms, where they smoke or troop about some leader, who may have an old revolver. They find or excavate caves, or perhaps roof them over; the barn is a blockhouse or a battleship. In the early teens boys begin to use frozen snowballs or put pebbles in them, or perhaps have stone-fights between gangs than which no contiguous African tribes could be more hostile. They become toughs and tantalize policemen and peddlers; "lick" every enemy or even stranger found alone on their grounds; often smash windows; begin to use sticks and brass knuckles in their fights; pelt each other with green apples; carry shillalahs, or perhaps air-rifles. The more plucky arrange fights beforehand; rifle unoccupied houses; set ambushes for gangs with which they are at feud; perhaps have secrets and initiations where new boys are triced up by the legs and butted against trees and rocks. When painted for their Indian fights, they may grow so excited as to perhaps rush into the water or into the school-room yelling; mimic the violence of strikes; kindle dangerous bonfires; pelt policemen, and shout vile nicknames.
