When did Helen Sekaquaptewa publish her autobiography and How was water precious to the traditional Hopi?

In her autobiography Me and Mine (1969), Helen Sekaquaptewa, who grew up as a traditional Hopi, wrote of what water meant to her people:

“Every drop of water was precious, and there was never enough.

From infancy we were taught to drink sparingly; even then, there were times when we were always thirsty. You never asked for a drink when visiting a neighbor’s house but went home to drink from your own water.

There was concern about the future of the village. Were the water supply to diminish and the population increase, what would become of the people?”
