perceptibly. It is particularly difficult to draw the line between the several kinds of stories and sketches he writes that involve supernaturalism of one kind and another. There is possible, however, a rough-and-ready distinction between those stories of his which are esoterically mystical and those which, while concerned with the supernatural, are concerned with it in the way familiar in old romance.
