A key was made and magnetized so thoroughly that never before was a piece of iron so yearningly full of the electric fluid. The whole thing was adjusted against the wall of the room, and then the men brought in the magnetized key to ascertain if their invention would work in practice. Simpson was carrying the key. No sooner had he entered the door than something began to pull him toward the magnet. He walked sideways, like a crab, resistingly, and could not help himself; and then, just as he had nearly reached the bell-shaped keyhole, he was whirled around, as is the end child in a school playground when they are playing "crack-the-whip," fairly in front of the keyhole, and literally hurled toward it, while the key shot fiercely into the lock. But there was not a sound; the rubber cushion had obviated that. Well, to say that those two young men were delighted would be to use but one of the commonplace, everyday, decent conversational expressions of the English language. They were simply wild. Since their latest conversation Jason B. Grampus had engaged in no further communication with Simpson. He thought it best to avoid all relations with the young man who could jest on serious occasions; and yet underlying his upper strata of thought was a dim and undefined impression that he would hear from that young man again. He did. The morning after the perfection of the invention Simpson called upon Mr. Grampus and calmly, coldly, and dignifiedly announced that his lock was complete, and that he was now about to install it in the Grampus front door. He suggested to Mr. Grampus that to avoid any encounters which might be embarrassing, the latter should suddenly discover some fault in his own front door--in the stained glass, or something of that sort--and have it taken off bodily and sent away to be remodeled; while a temporary door should be put in its place. The old gentleman listened amazed, and thought it all a farce; but then the word of Jason B. Grampus had gone out, and he must keep his word. "All right," he said. So the front door was sent down town and another one put in its place, and in that front door down town Simpson and Hastings established and firmly secured the marvelous electric lock and keyhole. Then the door was sent back and put in its place. The same day Simpson called at the office of Mr. Grampus and handed him a key, the ring of which was big enough to hold at least two fingers. Mr. Grampus grinned sardonically over this continuation of the jest. "That's a big ring," he said. "I am confident you'll not find it any too large," was Simpson's respectful answer. The old man grunted. "Will it unlock the door, and how? That is all I want to know." "It will," said Simpson; and so they parted.
