But the motive is not so obscure, after all. It is the same old one of profit without conscience. It took from the Health Department the supervision of the light, ventilation, and plumbing of the tenements, which by right belonged there, and put it in charge of a compliant Building Department, "for the convenience of architects and their clients, and the saving of time and expense to them." For the convenience of the architect's client, the builder, the lot was encroached upon, until of one big block which the Gilder Commission measured only 7 per cent was left open to the air; 93 per cent of it was covered with brick and mortar. Rear tenements, to the number of nearly 100, have been condemned as "slaughter-houses," with good reason, but this block was built practically solid. The average of space covered in 34 tenement blocks was shown to be 78.13 per cent. The law allowed only 65. The "discretion" that penned tenants in a burning tenement with stairs of wood for the builder's "convenience" cut down the chance of life of their babies unmoved. Sunlight and air mean just that, where three thousand human beings are packed into a single block. That was why the matter was given into the charge of the health officials, when politics was yet kept out of their work. [Illustration: The Old Style of Tenements, with Yards.] Of such kind are the interests that oppose betterment of the worker's hard lot in New York, that dictated the appointment by Tammany of a commission composed of builders to revise its code of tenement laws, and that sneered at the "laughable results of the Gilder Tenement House Commission." Those results made for the health and happiness and safety of a million and a half of souls, and were accounted, on every humane ground, the longest step forward that had been taken by this community. For the old absentee landlord, who did not know what mischief was afoot, we have got the speculative builder, who does know, but does not care, so long as he gets his pound of flesh. Half of the just laws that have been passed for the relief of the people he has paralyzed with his treacherous discretion clause, carefully nursed in the school of practical politics to which he gives faithful adherence. The thing has been the curse of our city from the day when the earliest struggle toward better things began. Among the first manifestations of that was the prohibition of soap factories below Grand Street by the Act of 1797, which created a Board of Health with police powers. The act was passed in February, to take effect in July; but long before that time the same legislature had amended it by giving the authorities discretion in the matter. And the biggest soap factory of them all is down there to this day, and is even now stirring up a rumpus among the latest immigrants, the Syrians, who have settled about it. No doubt it is all a question of political education; but is not a hundred years enough to settle this
