This double-decker was thus described by the Tenement House Commission of 1894: "It is the one hopeless form of tenement construction. It cannot be well ventilated, it cannot be well lighted; it is not safe in case of fire. It is built on a lot 25 feet wide by 100 or less in depth, with apartments for four families in each story. This necessitates the occupation of from 86 to 90 per cent of the lot's depth. The stairway, made in the centre of the house, and the necessary walls and partitions reduce the width of the middle rooms (which serve as bedrooms for at least two people each) to 9 feet each at the most, and a narrow light and air shaft, now legally required in the centre of each side wall, still further lessens the floor space of these middle rooms. Direct light is only possible for the rooms at the front and rear. The middle rooms must borrow what light they can from dark hallways, the shallow shafts, and the rear rooms. Their air must pass through other rooms or the tiny shafts, and cannot but be contaminated before it reaches them. A five-story house of this character contains apartments for eighteen or twenty families, a population frequently amounting to 100 people, and sometimes increased by boarders or lodgers to 150 or more." [Illustration: The only Bath-tub in the Block: it hangs in the Air Shaft.] The commission, after looking in vain through the slums of the Old World cities for something to compare the double-deckers with, declared that, in their setting, the separateness and sacredness of home life were interfered with, and evils bred, physical and moral, that "conduce to the corruption of the young." "Make for unrighteousness" said the commission of 1900, six years later. Yet it is for these that the "interests" of which the fire-chief spoke have rushed into battle at almost every session of the legislature, whenever a step was taken to arraign them before the bar of public opinion. No winter has passed, since the awakening conscience of the people of New York City manifested itself in a desire to better the lot of the other half, that has not seen an assault made, in one shape or another, on the structure of tenement-house law built up with such anxious solicitude. Once a bill to exempt from police supervision, by withdrawing them from the tenement-house class, the very worst of the houses, whose death-rate threatened the community, was sneaked through the legislature all unknown, and had reached the executive before the alarm was sounded. The Governor, put upon his guard, returned the bill, with the indorsement that he was unable to understand what could have prompted a measure that seemed to have reason and every argument against it and none for it.
