As I went under the new telegraph wire, I heard it vibrating like a harp high overhead. It was as the sound of a far-off glorious life, a supernal life, which came down to us, and vibrated in the lattice-work of this life of ours.Sept. 22
Yesterday and today the stronger winds of autumn have begun to blow, and the telegraph harp has sounded loudly. I heard it especially in the Deep Cut this afternoon, the tone varying with the tension of different parts of the wire. The sound proceeds from near the posts, where the vibration is apparently more rapid. I put my ear to one of the posts, and it seemed to me as if every pore of the wood was filled with music, labored with the strain - as if every fibre was affected and being seasoned or timed, rearranged according to a new and more harmonious law. Every swell and change or inflection of tone pervaded and seemed to proceed from the wood, the divine tree or wood, as if its very substance was transmuted. What recipe for preserving wood, perchance - to keep it from rotting - to fill its pores with music!Sept. 23
The telegraph harp sounds strongly today, in the midst of the rain. I put my ear to the trees and I hear it working terribly within, and anon it swells into a clear tone, which seems to concentrate in the core of the tree, for all the sound seems to proceed from the wood. It is as if you had entered some world-famous cathedral, resounding to some vast organ. The fibres of all things have their tension, and are strained like the strings of a lyre. I feel the very ground tremble under my feet as I stand near the post. This wire vibrates with great power, as if it would strain and rend the wood.
