Trees falling in the woods of Nova Scotia have a band of normally quiet hermits speaking out. The brothers and sisters of the Nova Nada Carmelite Hermitage in the Nova Scotia woods near Yarmouth live a very quiet life. They don't speak from dusk till dawn, and they keep silent for at least one full day a week. They spend long periods in prayer and meditation. But lately, their solitude has been broken by the sounds of chain saws. Timber giant J.D. Irving has been clear cutting the woods around the hermitage, and the 12 monks say the noise is undermining their way of life. Laura Knoy reached Sister Sharon Doyle by phone. Sister Doyle is the spokeswoman for the Nova Nada Carmelite Hermitage, where silence is fundamental.
