It was our first visit to Bayford Wood. A country walk, on a bright July day which was not quite as warm as it should be. A walk under an undecided sky, from time-to-time enhanced with inexplicable flurries of raindrops that fell like scattering beads. As we followed the track deeper into the woods, surrounded by tall trees, long growing and cathedral high, a small propeller plane buzzed over. It made us look. Then, with the quiet returned, our ears became tuned to the presence of countless myriad things high above us. Whispering things, hissing things, softly shushing things, filtering down their fine gossamer sounds in slow undulating waves. Lung easing. Chest expanding. Mind cleansing. All from up in the vaulted ceiling of green, forty feet above, millions upon millions of leaves, set in tiny individual motions by the breeze.  We found a grassy bank set back from the track, pushed through a hedge of ivy, and left the microphones alone to record while we went off to brew tea on a camping stove.
