The place reminded him then and later of the storm centre of a cyclone. Outside the tempests of Civil War raged. He could hear, as he sat in the quiet, book-lined room, the turbulent drums fitfully beating in tented camps far down the Tennessee River. Through the broad, old-fashioned window he saw the purple hills opposite begin to glow with a myriad of golden gleams, pulsing like fireflies, that told of thousands of troops in bivouac. He read the mystic message of the signal lights, shining with a different lustre, moving athwart the eminence, then back again, expunged in blackness as a fort across the river flashed out an answer.
