One afternoon, at low water, Mr. Isbister, a young artist lodging at Boscastle, walked from thatplace to the picturesque cove of Pentargen, desiring to examine the caves there. Halfway down theprecipitous path to the Pentargen beach he came suddenly upon a man sitting in an attitude ofprofound distress beneath a projecting mass of rock. The hands of this man hung limply over hisknees, his eyes were red and staring before him, and his face was wet with tears.He glanced round at Isbister's footfall. Both men were disconcerted, Isbister the more so, and, tooverride the awkwardness of his involuntary pause, he remarked, with an air of mature conviction, that the weather was hot for the time of year."Very," answered the stranger shortly, hesitated a second, and added in a colourless tone, "I can'tsleep."Isbister stopped abruptly.

Unwisely perhaps. I have followed the coast, day after day-from NewQuay. It has only added muscular fatigue to the mental. The cause of this unrest was overwork-trouble. There was something-"He stopped as if from sheer fatigue. He rubbed his forehead with a lean hand. He resumedspeech like one who talks to himself."I am a lone wolf, a solitary man, wandering through a world in which I have no part. I amwifeless-childless-who is it speaks of the childless as the dead twigs on the tree of life? I amwifeless, I childless-I could find no duty to do. No desire even in my heart. One thing at last I setmyself to do
