One hundred fifty acres of second-growth Douglas-fir and hemlock that Prentice and Virginia Bloedel let go quiet. The Reflection Pool sits at the bottom of a long yew allée, two hundred feet of black water that takes the sky in completely. Past it the Moss Garden runs through cedar shadow under fronds of sword fern. The residence at the top of the property is still standing, French Renaissance, white, oddly correct against the cedar. There are benches, but most of the walk is silent, and most of the people walking know it.
