A brief analysis of the preceding table will show the manner in which it is to be used. The first group of houses mentioned are those of one story, in which 164 families, comprising 503 persons, are found. Of these, 161 families, comprising 497 persons, occupy the entire house; while 3 families, comprising 6 persons, are found in first story tenements in houses of this class, but do not occupy the entire house. The largest number of families and persons are found in three story houses, there being in such houses 21,858 families and 91,935 persons. As before, these families and persons are classified, 1,193 families, including 7,383 persons, being found in occupancy of the entire house; 5,005 families, including 19,331 persons, in tenements confined to the first story exclusively; 318 families and 1,563 persons in tenements confined to the first and second stories; 182 families and 984 persons in tenements located on the first, second, and third stories; 926 families, comprising 4,189 persons, in tenements located in the first and third stories; 6,279 families and 26,109 persons in tenements located in the second story exclusively; 1,587 families and 7,547 persons in tenements located in the second and third stories; and 6,368 families, including 24,829 persons, in tenements exclusively confined to the third story.

This table will enable the reader to trace the character of the houses in which are located tenements of either of the specified classes represented in the table on page 134; for instance, if it is desired to trace the tenements exclusively confined to the basement, the first instance of such tenements will be found in

the table in houses containing a basement and one story. In houses of this class are found 41 families, comprising 169 persons, and from the classification at the right hand of the table, it is seen that two of these families, comprising three persons, are located exclusively in the basement. The next instance occurs in houses composed of a basement, one story, and attic. In houses of this class, 487 families, comprising 2,303 persons, occupy tenements, and 17 of these families, including 54 persons, are confined exclusively to the basement. This illustration will enable the reader to clearly understand the table.

The highest rented houses found in the city are those classed in the table as having a basement and eight stories, but in rented houses of this class only 8 families were living, including but 45 persons. Of these families, two were confined exclusively to the basement, one occupied a tenement located in the basement and first story, while the remaining families occupied tenements confined exclusively to the second, third, fourth, seventh, and eighth stories, respectively, the tenements of course being "flats."

WINDOWS IN RENTED TENEMENTS.

The next presentation shows the number of sleeping rooms without outside windows in the different rented tenements in the city, and indicates also the total number of rooms and total population found in tenements containing sleeping rooms of this kind. This information is classified in the table so as to show the outside and inside sanitary condition of the tenements in which such sleeping rooms were found.
