causes of this increase of crimes are the rapid growth of our population and wealth; the consequent luxury and corruption of, manners, particularly in the capital of the state; and the great number of indigent and vicious emigrants from Europe and the West Indies, driven hither by the disordered and distressful condi-tion of their native countries, or to escape the ven-geance of the laws. More than three fourths of the whole number of crimes are committed in the city of New York. Its population has almost doubled in ten years, and the increase of its trade and wealth is unequalled in the history of commercial states.
