he pilot glanced at his instruments and saw that the automatic gyro-apparatus was functioning properly. Then he moved over to the radio and threw the switch that put the key in circuit instead of the microphone. Rapidly he ticked off the three dots, three dashes, and again three dots that spelled the dread danger signal of the air. Over and over he repeated the signal, and then he listened for results.

"It worked!" he gloated, after a moment. "They're all signing off—the broadcasters. The Navy Yard in Brooklyn gives me the go-ahead."

He pounded out the absurd message with swift fingers, pausing occasionally to ask a pertinent question of Van or Bart. At Van's request he added a warning to all residents of New York State west of the Hudson River and of northern New Jersey to flee their homes without delay. He even asked that the message be relayed to the governors of the two states, and that Governor Perkins of New York be advised that they were on their way to Albany to discuss the situation. But he balked at the story of the Lunarians, telling instead the equally strange truth regarding the origin of the deadly growth, and adding the names of Van and Bart to lend authenticity to the tale.

Then he signed off and switched the radio receiver to the loud speaker before returning to the pilot's seat.

Bart tuned in on the various broadcasters as they resumed their programs, finally settling on WOR, Newark, whose announcer was reading the strange message to his radio public with appropriate comment. A crime and an outrage he called it, an affront to the industry and to the public. An insult to the government of the United States. But wait! A telephone call had just been received at the station from the village of Sloatesburg. A reputable citizen of that town had reported the red growth at the edge of the State road—huge red earthworms wriggling across the concrete. Another call, and another! The announcer's voice was rising hysterically.

"It did work, Bart," Van exulted. "Now the hell starts popping."


overnor Perkins met them in person when they arrived at the Municipal Airport in Albany. A great crowd had gathered in the shadows outside the brilliance of the flood lights, and a police escort rushed them to the governor's private car.

"Here's where you go to the Bastille for socking that cop," Van observed. His spirits had risen appreciably since that successful S. O. S. call.
