His eyes twinkled over this mild witticism, and the party broke up with a scraping of chairs. A couple of hours later, the blue line of Sandy Hook was visible, and then the vague cliffs of the New York skyscrapers. The clouds had cleared away after the rain of the last few days; not even a speck of mist hung in the air and everything stood out bright and clear. The colonists felt a pang of emotion grip them as they watched the tall towers of the city rise over the horizon, straight and beautiful as they had always stood, but now without a sign of life or motion, all the busy clamor of the place hushed forever. Of the tetrapteryxes or "dodos" as the Australian had called them, there was no sign. The sky bent high, unbrokenly blue, not a flicker of motion in it. Murray Lee felt someone stir at his side and looked round. "Oh, damn," said Gloria Rutherford, "it's so beautiful that I want to cry. Did you ever feel like that?" He nodded silently.... "And those birds--isn't it a shame somehow that they should have the most beautiful city in the world?" The shrill of a whistle cut off his words. With marvelous, machine-like precision, the sailors moved about the decks. The _Brisbane_ lost way, came to a halt, and there was a rush of steel as the anchor ran out. Captain Entwhistle came down from the bridge. "I don't see anything of your dodos yet," he said. "Do you think it would be wise to send out a landing party, Mr. Ruby?" "Most certainly not," said Ben. "You don't know what you're up against yet. Wait till they come round. You'll have plenty to do." The captain shrugged. Evidently he was not at all unwilling to match the Australian navy against anything the dodos might do. "Very well, I'll accept your advice for the present, Mr. Ruby. It is near evening in any case. But if there is no sign of them in the morning, I propose to land and look over the city." But the landing was never accomplished. For, in the middle of the night, as Ben, Murray and Gloria were seated in the chartroom of the ship, chatting with the young lieutenant on duty there, there came a quick patter of feet on the deck, and a shout of "Light, ho!" "There are your friends now, I'll wager," said the lieutenant. "Now watch us go get 'em. If you want to see the fun, better go up on the bridge. All we do here is wrestle slide-rules." Hastily the three climbed the bridge, where a little group of officers was clustered. Following the direction in which they were looking, they saw, just above the buildings on the Jersey shore, what looked like a tall electric sign, burning high in the air and some distance away, with no visible means of support. "What do you make of it?" asked Captain Entwhistle, turning and thrusting a pair of glasses into Ben's hands. Through them he could read the letters. Printed in capitals, though too small to be read from the ship with the naked eye, he saw: "SOFT MEN EXIT. HARD MEN ARE WORKERS BELONGING. MUST RETURN. THIS MEANS YOU."
