The governor raised his hands in a gesture of resignation. "I know nothing of these matters, and it is your business to know. I accept your assurances without reservation. Now, what do we do?"

The scientists had not only conceived the solution, but had a detailed plan of action. Within a half hour, the loud-speaker had been removed from the plane, and Rick was flying Governor Montoya, Hartson Brant, and Esteben Balgos to Trinidad.

Arrangements had been made by phone while they were en route. A car, sent by the President of the West Indies Federation, picked them up at the airport and whisked them to the Federation's headquarters.

The President listened to the story with intense interest, then summoned the American ambassador and the representatives of Venezuela and Colombia.

After a detailed discussion by Hartson Brant of the properties and limitations of nuclear explosions, the conference agreed. Immediate action was called for. The Venezuelan and Colombian representatives hurried off to notify their governments, while the President of the Federation put in a conference call to the United States, to the Chairman of the Atomic Energy Commission, the Secretary of Defense, the Secretary of State, and the President's Special Assistant for Science and Technology, who happened to be an old friend of Hartson Brant's.

A personal phone call from a head of state was without precedent—especially a conference call. The U. S. officials were located within an hour, and the call put through. On the West Indies end were the Federation's President, the U. S. ambassador, Governor Montoya, and Hartson Brant, speaking from four different rooms. Rick hung over his father's chair, listening.

The Federation's President introduced himself and described the problem briefly. Then he introduced the governor. Montoya said briefly, "Gentlemen, we must have help or the island of San Luz will perish. I ask help on behalf of my 32,000 people."

The Federation's President then introduced Hartson Brant. Rick gathered that the U. S. President's Special Assistant and the Chairman of the Atomic Energy Commission both greeted him warmly as an old friend.

The scientist outlined the problem and its solution. He continued, "According to our estimates, we will need ten kilotons in order to have a margin of safety. It will take as many Seabees or engineers as necessary to drive a tunnel. The tunnel dimensions will depend on what machinery you can get to us. I leave that to your experts. We will also need about five thousand sea-based troops to handle the island population. We may have to carry them bodily to safety. Now, can it be done?"

There was silence as the scientist listened. Rick stood on one foot, then the other, waiting. He could hear the mumble of voices through the earphone but could make no sense out of it.
