One of the chief virtues of the _mo-jio_ is to render the person of the wearer invulnerable; and many an unlucky _mo-jio_ has succumbed to the popular test, which is to wrap it in a cloth and fire a bullet at it at short range. If the man misses the cloth, the authenticity and power of the charm is at once established; if the stone is fractured it is held not to be a real _mo-jio_. Fire will not consume a house which contains one, though I never heard of this ordeal being attempted. Last but not least is the known fact that the owner of a real _mo-jio_ can cut a rainbow in half with it. Certain recent happenings have suggested that the name “aviator-stone” would be a peculiarly appropriate designation for meteorites, and indeed this new name would only serve to emphasize the legendary belief, that he who bore with him a meteorite when he was in deadly peril would escape all injury. By a strange coincidence those who are willing to take great risks and chances are generally more or less superstitious regarding small things, and a daring aviator recently remarked that on one occasion, when his machine had suddenly fallen fifty feet, he felt for his tie and said to himself: “This accident has happened because I forgot to put on my opal pin, but I have been saved from injury because I carried a meteorite.” This aviator, having mentioned the incident to Harmon, a few minutes before the latter made his successful attempt to win the Doubleday-Page aviation prize, Harmon immediately took the meteorite which had been shown to him, saying: “Let me have it.” He accomplished his task, and although both the competing machines were injured, the aviators themselves were saved. A meteorite, of course, cannot be claimed to be a preventive of danger on all occasions, but several who have always carried them have seemed to escape all sorts of harm. Some years ago a meteorite was given to Edward Heron Allen, the famous writer on palmistry and the violin, and this gifted man always wore it about him. One morning he awakened to find that the entire roof above him had fallen in, except just that portion over his bed. He told the story to one of the best known ladies in Boston; one who is known for her public spirit, her love of art and her faultless manner of entertaining. This lady successfully urged Allen to give her the meteorite. A few days later, while out driving, a great truck with two runaway horses attached to it struck her carriage. Instinctively she raised her muff to protect her face; the muff was almost cut in two, but the lady was not hurt. A few days later, while she was walking under some scaffolding, it fell, and the open part where the hoists went up proved to be just where she stood. Although surrounded by ruin, she remained unharmed. III Stones of Healing
