future use. Those who can afford to do so buy their water
from tankers, spending on average one third of their monthly

Many people can afford neither; meaning girls and women

Thirty or more years ago, one who stood at the foot of Main Street, Winnipeg, in front of the stone gate
leading to the inner court of Fort Garry, and looked up across the river flats, would have seen a procession as
