TO INSURE healthful living, domestic wastes must be disposed of.
Primitive wanderers and too often present-day tourists deposit their
wastes promiscuously and move on when the surroundings become foul.
This is impractical in built-up communities. Therefore, in most cities
and in some rural areas sanitary codes regulate the disposal of wastes.
