We can see in the gladiatorial shows of Rome, which degenerated into the butchery alike of beasts and men, the sure sign of moral decay which ended in the destruction of the empire and the breaking up of the great influence it had cast over the world. It is altogether necessary that we keep our own amusements and recreations within that field which will be prophetic, not of destruction, but of development. It is characteristic of almost the entire American life that it has a most worthy regard for clean and manly sports. It has little appetite for that which is unwholesome or brutal.
