I SOMETIMES wonder how much these have changed since my boy's time. Of course they differ somewhat from generation to generation, and from East to West and North to South, but not so much, I believe, as grown people are apt to think. Everywhere and always the world of boys is outside of the laws that govern grown-up communities, and it has its unwritten usages, which are handed down from old to young, and perpetuated on the same level of years, and are lived into and lived out of, but are binding, through all personal vicissitudes, upon the great body of boys between six and twelve years old. No boy can violate them without losing his standing among the other boys, and he cannot enter into their world without coming under them. He must do this, and must not do that; he obeys, but he does not know why, any more than the far-off savages from whom his customs seem mostly to have come. His world is all in and through the world of men and women, but no man or woman can get into it any more than if it were a world of invisible beings. It has its own ideals and superstitions, and these are often of a ferocity, a depravity, scarcely credible in after-life. It is a great pity that fathers and mothers cannot penetrate that world; but they cannot, and it is only by accident that they can catch some glimpse of what goes on in it. No doubt it will be civilized in time, but it will be very slowly; and in the meanwhile it is only in some of its milder manners and customs that the boy's world can be studied.
