Take the question of overcrowding, for instance. Quite often you have eight or even ten people living in a three-roomed house. One of these rooms is a living-room, and as it probably measures about a dozen feet square and contains, besides the kitchen range and the sink, a table, some chairs, and a dresser, there is no room in it for a bed. So there are eight or ten people sleeping in two small rooms, probably in at most four beds.
