Yesterday and to-day 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 fiber was affected and being seasoned or timed, rearranged according to a new and more harmonious law.
