 A solemn feeling seemed to be impressed upon those who witnessed the little performance as if some grave mystery hovered there around the simple scene, notwithstanding the results were confidently expected, although the experiments had been continued for nearly two days before the line would 'work,' and even then it continued to transmit signals only about three hours, when the circuit became suddenly inoperative by the moving away of the upper electric body.Hence it is that high regions must be sought where disturbing influences cannot invade, where statical energy is stored in a vast unbroken element, enabling a line to be worked without interruption or possible failure.No speculation need be indulged as to whether the theory is correct, for theory and speculation must stand aside whether they will or not, and square themselves with the demonstrated truth."
