"That's where we'll use our disintegrators," explained Art. "We'll blast a path through which we can lead these people to safety." Art got on the televisor and contacted the government broadcasting center in San Francisco. "Do you have a news broadcast on now?" he asked. The girl clerk answered in the affirmative. "Please put me on," Art begged. "I'm from Interplanetary Research. Here's my badge. This is a serious emergency. The lives of millions of people are hanging in the balance. You must put me on the air!" A moment later, the news broadcast which was even then picturing the catastrophe in billions of homes all over the world, was abruptly cut off, and Art's face appeared in its stead. "Fellow citizens, you all know the desperate situation here in Los Angeles--but do you know that you can save a life, perhaps a dozen? There are ten million people here who face a terrible death unless they are picked up immediately. Hop in your fliers and get right down here! There is no danger for a ship which hovers a little above the ground. _Do not try to land!_ The Los Angeles Traffic Patrol will guide you to proper zones. Please hurry. Thank you." Art snapped off the switch and turned to the chief. "Now, let's try to make some kind of map of the already devastated areas. We'll have to check in some manner to be sure there are no living people left in them, then blast our path through with the disintegrators." * * * * * Horne readily assented to this plan, and dispatched a number of patrolmen to examine closely the ruined sections. All vicinities which had been taken over entirely by the destroyers, were to be marked by dropping tiny smoke bombs which would send up a dense column of smoke. As the commissioner and Art entered the latter's flier and took off, Art explained the difficulties of using a disintegrator. "The atomic disintegration of a lump of matter the size of your fist sets off an explosion strong enough to blow one of these big buildings to small fragments. You can imagine what would happen to yourself and the surrounding country if you merely turned a disintegrator beam on the ground, or against a building near you. We tone down the effect somewhat by causing these pistols which I have here, to project a ray about the diameter of a hair from your head. Not only that, but the ray is immediately cut off, lasting only for the duration of one wave length. Even so, the firing of one is a plenty tricky business." In an hour's time the air patrolmen had laid out a winding, serpentine trail over ten miles long through the bristling mounds of debris. A warning broadcast was sent directing all citizens within sight of the smoke to get underground, lie low, and plug their ears.
