They had no better friend. When the unhappy plight of the persecuted push-cart men--all immigrant Jews, who were blackmailed, robbed, and driven from pillar to post as a nuisance after they had bought a license to trade in the street--appealed vainly for a remedy. Colonel Waring found a way out in a great morning market in Hester Street that should be turned over to the children for a playground in the afternoon. But though he proved that it would pay interest on the investment in market fees, and many times in the children's happiness, it was never built. It would have been a most fitting monument to the man's memory. His broom saved more lives in the crowded tenements than a squad of doctors. It did more: it swept the cobwebs out of our civic brain and conscience, and set up a standard of a citizen's duty which, however we may for the moment forget, will be ours until we have dragged other things than our pavements out of the mud. [Illustration: A Tammany-swept East Side Street before Colonel Waring's Day.] Even the colonel's broom would have been powerless to do that for "the Bend." That was hopeless and had to go. There was no question of children or playground involved. The worst of all the gangs, the Whyos, had its headquarters in the darkest of its dark alleys; but it was left to the police. We had not begun to understand that the gangs meant something to us beyond murder and vengeance, in those days. No one suspected that they had any such roots in the soil that they could be killed by merely destroying the slum. The cholera was rapping on our door, and, with the Bend there, we felt about it as a man with stolen goods in his house must feel when the policeman comes up the street. Back in the seventies we began discussing what ought to be done. By 1884 the first Tenement House Commission had summoned up courage to propose that a street be cut through the bad block. In the following year a bill was brought in to destroy it bodily, and then began the long fight that resulted in the defeat of the slum a dozen years later.
