8.  Rob Acquires New Powers
"I have seen the folly of sending you into the world with an offensive instrument, yet with no method of defense," resumed the Demon, presently.  "You have knocked over a good many people with that tube during the past week."
"I know," said Rob; "but I couldn't help it.  It was the only way I had to protect myself."
"Therefore my next gift shall be this Garment of Protection.  You must wear it underneath your clothing.  It has power to accumulate and exercise electrical repellent force.  Perhaps you do not know what that means, so I will explain more fully.  When any missile, such as a bullet, sword or lance, approaches your person, its rush through the air will arouse the repellent force of which I speak, and this force, being more powerful than the projective force, will arrest the flight of the missile and throw it back again.  Therefore nothing can touch your person that comes with any degree of force or swiftness, and you will be safe from all ordinary weapons.  When wearing this Garment you will find it unnecessary to use the electric tube except on rare occasions.  Never allow revenge or animosity to influence your conduct.  Men may threaten, but they can not injure you, so you must remember that they do not possess your mighty advantages, and that, because of your strength, you should bear with them patiently."
