I have never heard of this, despite having experienced rural life both among upper and lower classes. I expect that Ellen Barry made it up, or - more likely - was conned by one of her Indian assistants/translators and swallowed it up.
Having said that, the article is correct overall that life of rural Indian women is hard and governed by patriarchal rules - they are expected to be house bound etc. The description of menstrual restrictions is also accurate.
Overall the article did ring of truth and was optimistic - surprisingly for Ellen Barry and the New York Times.
