But he had only half the formula, the half he himself had developed. The other part was locked in the brain of Ganeth-Klae, and Ganeth-Klae had disappeared. What had become of him was a mystery. Norris perhaps had felt the loss more than any one, and he had offered the major part of his savings as a reward for information leading to the scientist's whereabouts.

Our party—eighteen couples and Navigator Norris—had gathered together and subsequently left Earth in answer to a curious advertisement that had appeared in the Sunday edition of the London Times.

WANTED: A group of married men and women, young, courageous, educated, tired of political and social restrictions, interested in extra-terrestrial colonization. Financial resources no qualification.

After we had been weeded out, interviewed and rigorously questioned, Norris had taken us into the hangar, waved a hand toward the Marie Galante and explained the details.

The Marie Galante was a cruiser-type ship, stripped down to essentials to maintain speed, but equipped with the latest of everything. For a short run to Venus, for which it was originally built, it would accommodate a passenger list of ninety.

But Norris wasn't interested in that kind of run. He had knocked out bulkheads, reconverted music room and ballroom into living quarters. He had closed and sealed all observation ports, so that only in the bridge cuddy could one see into space.

"We shall travel beyond the orbit of the sun," he said. "There will be no turning back; for the search for a new world, a new life, is not a task for cowards."

Aside to me, he said: "You're to be the physician of this party, Bagley. So I'm going to tell you what to expect when we take off. We're going to have some mighty sick passengers aboard then."

"What do you mean, sir?" I said.

He pointed with his pipe toward the stern of the vessel. "See that ... well, call it a booster. Ganeth-Klae designed it just before he disappeared, using the last lot of Indurate in existence. It will increase our take-off speed by five times, and it will probably have a bad effect on the passengers."
