at least one-tenth of the floor area of the room.

opening may, in every case, extend to the top of
the window.
In the 1909 report statistics were given as to the health
of persons living in new and old houses in North Woolwich,

earth damp like the older houses.
31. Council's Houses. All the Council's 25 houses in
North Woolwich were occupied throughout the year, with the
exception of four, which were vacant 11, 9, 6, and 2 weeks
respectively. The number of persons housed is about 130,
or 5 to a house. For particulars as to rent and cubic space
of these houses, see Annual Eeport, 1904, page 70.
