"Now, then," said Moreiko, "if you must demonstrate your power, divide the moon. But remember that separating the earth into two parts generates _interplanetary_ strife instead of mere global argument. Have I answered your problem?" * * * * * Things are less troublesome now. A bit of impending disaster will draw people together; it is often a sorry fact that once the disaster is averted, those people will again revert to their former animosity. But all that the people of the earth have to do to remember is to look upwards. There are two moons in the sky, moons once hemispherical but whose edges daily crumble into crude spheres. A nice reminder--and also another problem for Professor Milton. He has not yet returned to his Institution, for he is living in a glass dome on one of the moons, trying to work out the problem of bringing them together again. He claims it to be but a matter of time. THE END
