Watching the colored children for many months in their play and work, I have looked for possible distinctive traits. The second generation of New Yorkers greatly resembles the "Young America" of all nationalities of the city, shrill-voiced, disrespectful, easily diverted, whether at work or at play, shrewd, alert, and mischievous--the New York street child. I remember once helping with a club of eight boys where seven nationalities were represented, and where no one could have distinguished Irish from German or Jew from Italian, with his eyes shut. Had a Negro been brought up among them he would quickly have taken on their ways. Of the colored children who model their lives after their mischievous young white neighbors, many outdo the whites in depravity and lawlessness; but among the boys and girls who live by themselves, as on San Juan Hill, one sees occasional interesting traits. The records of the Children's Court of New York (Boroughs of Manhattan and the Bronx) throw a little light on this matter, and are sufficiently important to quote with some fulness. For the three years studied, 1904, 1905, 1906, I tabulated the cases of the colored children brought before the court, and also the cases of the children of the Tenth and Eleventh Wards, chiefly Hungarians and Russian Jews, expecting to find, in two such dissimilar groups, interesting comparisons. The following table shows the result of this study. The court in its annual report gives the figures for the total number of arrests which I have incorporated in my table: RECORD OF ARRESTS IN CHILDREN'S COURT OF MANHATTAN AND THE BRONX FOR 1904, 1905, 1906 Key to Column Headers-- A: No. of children.
