He sees a vision of flying dust, broken branches, prostrate trees. Possibly he draws his deductions from the theory of the sliding faculty of sand,—which phenomenon he has, perhaps, suffered from; and he has seen trees overturned by sand-slides, and, as the tempest beats unfelt upon his adamantine scales, he thinks the sand-power is at work, and would debate all day with any thin-skinned animal who would assert that it was done by a tempest of air. “I never saw it, I never felt it,” Signor Armadilla would perpetually growl forth; and, so far as he was concerned, the air would be sand, and his neighbor a credulous, half-crazy believer in a thing perfectly intangible. He never could attribute the results of a tempest to any force which is not within the range of his experience. He is where he was, but the oak is where it was not. He stood upon a sound place, the oak upon a slide,—that’s all. There was no hurricane. Thus it is that while a thing may exist, it may not always be apparent, and if apparent, only to a few. Men take views according to the texture of their mental cuticle, mercurial or otherwise, thick or thin; and can decisions based upon such capricious contingencies be accepted as a philosophic solution of a doubt, or a truth? But I shall, farther on in my recital, have to deal more practically with this topic, because I shall be drawn to its revelation by the inevitable force of circumstances and incidents. II. THE INCIDENTS. Two months previous to the murder of the Joyce children I had been residing at the house of an acquaintance, a mile away from the village of Jamaica Plain. The front of the house looked out upon the road leading from Boston and passing through the village of Jamaica Plain far away into the back country, and onward,—a pleasant drive for those city dwellers who had only afternoon opportunities for rural inhalation. The rear of the house gave view of a meadow watered by a tiny rivulet and up to the woods of Bussey. This rivulet was the one that went by the body of the boy, and where it was concealed by its woods and weeds. The distance from our back porch to the spot where the body of the boy was found, was about four hundred yards, and to where the body of the girl was discovered, probably twice or thrice that number; so I was rusticating near the footlights of the theatre, little dreaming that, when the curtain rose, how terrible would be the drama that would drip the stage with blood.
