There is another reason for this. We have told how Brooklyn sold her birthright when she threw off her political individuality and made herself a borough of an enlarged New York. Perhaps it would be more true to say that she mortgaged that birthright the very hour when the Brooklyn bridge, then new, took up the fullness of its mighty work. In the weaving of that bridge is wrapped one of the little-known tragedies of Brooklyn--the immensely human story of Roebling, its designer and its builder, who suffered fatal injuries upon it and who died a lingering death before it was completed. Roebling's apartments were upon a high crest of Brooklyn Heights and the windows of his sick-room looked down upon the workmen who were weaving the steel web of the bridge. In the last hours of his life he could see the creation of his mind, the structure that was about to be known as one of the eight modern wonders of the world, being made ready for its task of the long years. The coming of that first bridge began the transformation of Brooklyn; although for a long time Brooklyn did not realize it. The New England element within her population did not even realize it when she gave up her political identity as a city. Then something else happened. Two miles to the north of the first bridge another was built--this with its one arm touching the East Side of Manhattan--the most crowded residence district in the new world--while its other hand reached that portion of Brooklyn, formerly known as Williamsburgh. We have already spoken of Williamsburgh--in its day a city of some promise but for sixty years now part of Brooklyn. In the greater part of these sixty years it hung tenaciously to its personality. Back of it was a great area of regular streets and small houses known as the Eastern District. The folk who lived there called themselves Brooklyn folk. Williamsburgh was different. Its folk were glad to give themselves the name of the old town, although the pattern of its streets ran closely into the pattern of the streets of the community which had engulfed it. They held themselves a bit by themselves. They had their own shops, their own theater, their own clubs, their own churches, their own schools. They also had the opportunity of seeing the social and the business changes that the development of the first bridge had wrought in old Brooklyn; how Fulton street from the old City Hall down to the ferry-house had lost its gayety and was entering upon decadence.
