Rev. W. M. Martin, the Superintendent of the City Mission of Brooklyn, presents some surprising facts concerning the growth of that city. He states that its population has increased in thirty-five years from 59,000 to 600,000 and has doubled in fifteen years; that it has 546 miles of streets, 335 of them paved, or as many as New York; that it has a water front of twenty-five miles; that 8,000 vessels were at its wharves in 1881, while New York had only 6,000; that, while of the 244,000 families in New York, 160,000 live in tenement houses, only 31,000 of the 124,000 families in Brooklyn were of this class. Though it is called the City of Churches, it has only 269, and a great part of these are in the old wards, in some of which there is a church to every 1,000 inhabitants, while in several of the new ones there is only one to every 10,000.—Ex.
