I love the wind, the way it animates the landscape by setting trees into motion and sends clouds scudding across the sky. Samarkand is not only a senior living facility, but also an arboretum, with 350 individual trees representing 35 species, many of them labeled. Here I can further hone my skills identifying trees. As Canary Island Pines sift the wind with their slender needles, they murmur and sigh. With their long leathery leaves, blue gum eucalyptus trees sound in a good wind like falling water. The palms are the noisiest of all, and their colliding fronds remind me of the sound of a downpour falling on a metal roof.

Recently, three of us decided to listen to trees in a different way. We engaged retired doctor Bill Macpherson and his stethoscope to hear the sounds produced by both a redbud and a sycamore tree that were each producing a new crop of fresh leaves. Pressing the cup of the stethoscope against the thin bark, we each got different results. Bill heard a sound like water rushing up a pipe. I heard faint popping sounds and a low-pitched gurgle. Ann Allen, perhaps less susceptible than Bill and I, heard nothing. We plan to wait for a hot day and try again.
