The metropolitan sewage was discharged untreated into the river, and the heavier solids deposited over the river-bed, while the lighter parts flowed backwards and forwards on the tide.
I do not think Americans would tolerate widespread, untreated hunger in this nation as long as it could afford otherwise.
