The year is at the top, and its record of commitments of petty girl thieves at the bottom. The tendency is steadily downward, it will be seen, and downward here is the safe course. The police court arraignments for what is known as juvenile delinquency, which is, in short, all the mischief that is not crime under the code, make the following showing, starting with the year 1875, the upper line representing the boys and the lower the girls: [Illustration: CHART B.] Taking, finally, the commitments of girls under twenty for all causes, in thirteen years, we have this showing: [Illustration: CHART C.] These diagrams would be more satisfactory if they always meant exactly what they seem to show. The trouble is that they share in the general inapplicability to the purposes of scientific research of all public reports in this city (save those of the Health Department, which is fortunate in possessing a responsible expert statistician in Dr. Roger S. Tracy) by reason of lack of uniformity or otherwise. When one gets down to the bottom of a slump like that between the years 1888 and 1889, in the last diagram, one is as likely to find a negligent police clerk or some accidental change of classification there as an economic fact. Something like this last is, I believe, hidden in this particular one. The figures for 1891 maintain the point reached in 1887 and in 1890. However, the important thing is that the decrease has gone on more or less steadily through good years and bad since the children's societies took the field, while the population has increased as never before. Had these forms of disorder even held their own, the slope should have been steadily upward, not downward. In this there is encouragement, surely. There is enough left to battle with. The six lodging-houses sheltered in the last twelve years 149,994 children, 8,820 of them girls. We are not near the end yet. The problem is a great one, but the efforts on foot to solve it are great and growing. It has been a forty years' fight with poverty and ignorance and crime, and it is only just begun. But the first blow is half the battle, it is said, and it has been struck in New York, and struck to win. CHAPTER XV. PUTTING A PREMIUM ON PAUPERISM
