The Irish moved from semi-slavery in Ireland to freedom in America only a few years before the Negro gained emancipation. After a century and a quarter, or less, the Irish are a leading power in the United States, and the Negroes remain on the lowest strata. The basic difference between the Irish and the Negro has not been color: it has been character. The Negroes demand more aid, i. e., more slavery and slave-care, and dwell on their sufferings. The Irish have instead looked to the present and future and helped shape America. It is a significant difference that cannot be explained altogether by color or environment. The Chinese also came to the United States under very difficult circumstances and similarly overcame them.
