All these three, the reputed pests of the family, society, and the world, are but loiterers from the march, bad boys, or dull ones. Criminals are a class of such; savages are nations thereof--classes or nations that for some cause do not keep up with the movement of mankind. The same human nature is in us all, only there it is not so highly developed. Yet the bad boy, who to-day is a curse to the mother that bore him, would perhaps have been accounted brave and good in the days of the Conqueror; the dangerous class might have fought in the Crusades and been reckoned soldiers of the Lord whose chance for heaven was most auspicious. The savage nations would have been thought civilized in the days when "there was no smith in Israel." David would make a sorry figure among the present kings of Europe, and Abraham would be judged of by a standard not known in his time. There have been many centuries in which the pirate, the land-robber and the murderer were thought the greatest of men. Now it becomes a serious question, What shall be done for these stragglers, or even with them? It is sometimes a terrible question to the father and mother what they shall do for their reprobate son who is an offence to the neighborhood, a shame, a reproach and a heart-burning to them. It is a sad question to society, What shall be done with the criminals--thieves, housebreakers, pirates, murderers? It is a serious question to the world, What is to become of the humbler nations--Irish, Mexicans, Malays, Indians, Negroes?
