Ten minutes later and I and my escort were bowling merrily over the ground in the direction of the Crow's Nest. It was early autumn, and the cool evening air, fragrant with the mellowness of the luscious Virginian pippin, was tinged also with the sadness inseparable from the demise of a long and glorious summer. Evidences of decay and death were everywhere--in the brown fallen leaves of the oaks and elms; in the bare and denuded ditches. Here a giant mill-wheel, half immersed in a dark, still pool, stood idle and silent; there a hovel, but recently inhabited by hop-pickers, was now tenantless, its glassless windows boarded over, and a wealth of dead and rotting vegetable matter in thick profusion over the tiny path and the single stone doorstep. "Is it always as quiet and deserted as this?" I asked of my companion, who continually cracked his whip as if he liked to hear the reverberations of its echoes. "Always," was the reply, "and sometimes more so. You ain't used to the country?" "Not very. I want to try it by way of a change. Are you well versed in the cry of birds? What was that?" We were fast approaching an exceedingly gloomy bit of the road where there were plantations on each side, and the trees united their fantastically forked branches overhead. I thought I had never seen so dismal-looking a spot, and a sudden lowering of the temperature made me draw my overcoat tighter round me. "That--oh, a night bird of some sort," Mr. Baldwin replied. "An ugly sound, wasn't it? Beastly things, I can't imagine why they were created. Whoa--steady there, steady." The horse reared as he spoke, and taking a violent plunge forward, set off at a wild gallop. A moment later, and I uttered an exclamation of astonishment. Keeping pace with us, although apparently not moving at more than an ordinary walking pace, was a man of medium height, dressed in a panama hat and albert coat. He had a thin, aquiline nose, a rather pronounced chin, was clean-shaven, and had a startlingly white complexion. By the side of him trotted two poodles, whose close-cropped skins showed out with remarkable perspicuity. "Who the deuce is he?" I asked, raising my voice to a shout on account of the loud clatter made by the horse's hoofs and the wheels. "Who? what?" Mr. Baldwin shouted in return. "Why, the man walking along with us!" "Man! I can see no man!" Mr. Baldwin growled. I looked at him curiously. It may, of course, have been due to the terrific speed we were going, to the difficulty of holding in the horse, but his cheeks were ashy pale, and his teeth chattered. "Do you mean to say," I cried, "that you can see no figure walking on my side of the horse and actually keeping pace with it?" "Of course I can't," Mr. Baldwin snapped. "No more can you. It's an hallucination caused by the moonlight through the branches overhead. I've experienced it more than once." "Then why don't you have it now?" I queried.
