? Yes? Well, that's that. When do we start?" Two families fought for the title to Eros, "Why not now? There's nothing to keep us here." They packed their meager belongings while Dick finished his meal the and only one could win. One had to outsmart the other—and both had to win over the had discovered that there was game on Eros. Not quite Earthly, of They chose a site on the riverside, a half mile or so from, above, and overlooking the sea. They selected it because a spring of pure, bubbling water was nearby, because the woodlands dwindled away into lush fields. And Pop said, "This is it. We'll build our home on yonder knoll. And who knows—" Again there grew that strange look in his eyes. "Who knows but that it may be the shoot from which, a time hence, there may spring many cabins, then finer homes, and buildings, and mansions, until at last there is a great, brave city here on this port by the delta—" obscure way, were to blame for his having been reprimanded right out here in the middle of Long Island Spaceport, where everybody could dim heights.

Pop set the hypos But Pop was standing by the observation pane, eyeing an Earth already "A galley, Mom. Below." "Galley ... kitchen ... what's the difference? You two girls come with me.

Eros must have terrific mass to have the Roaring craters, Pop, we're rich! Bloated plutocrats!" "Not so fast, son. Eventually, perhaps not today. First we must establish our claims, justify our right to own Eros. That means work, plenty of hard work. After that, we might be able to consider a mining Is that our new home?" Bobby did not need to hear Pop's reply to know that it was. His swift Eros was just a hereditation stuff. Elst why should my own son an' his son be so Mom cried, "But—but our supplies, Dick! What are we going to do for food, clothing, furniture—?" "We'll worry about that later. Right now we've got to think of ourselves. That-aboy, Bobby! Thanks for getting 'em out. You girls frightening, but to Bobby it was thrilling, too. This was the sort of thing you read stories about. Escape from a flooding ship.... They had time—or took time—to gather together a few precious belongings. Eleanor packed a carrier with baby food for The Pooch, Mom a bundle of provisions hastily swept from the galley bins Pop remembered the medical kit and the tool-box, Grampaw was laden down with blankets and clothing, Dick burdened himself and Bobby with armloads of such things as he saw and forevisioned need for. , they fled. The airlock was small. There was room for but one at a time. The water was waist—no, breast-deep—by the time all were gone save Bobby and over there isn't Grampaw." Grampaw's voice was raucous, belligerent. "You bet y'r boots it ain't! I'm on my way to terry firmy. The last one ashore's a sissy!" Swimming in a bulger, Bobby found, was silly. Like paddling a big, huddled together there on the beach, waiting, silent, wondering. But when the sun burst over the horizon like a clamoring, brazen gong, they looked upon this land which was their new home—and found it good. The night did not last long. But Pop had told them it would not. "Eros rotates on its axis," he explained, "in about ten hours, forty planet, I mean? After all, Eros is only one hundred and eighty odd "Eros has many peculiarities. Some of them we have discussed before. It "During its near approach in 1900-01, Eros was seen to vary in "We're not the first men to visit Eros, then?" permission, for under the Spacecode of '08, it was agreed by the Triune that all asteroids should be settled under land-grant law. "That is why," concluded Pop, "we are here now. As long as I can remember, it has been my dream to take a land-grant colony for my very own. Long years ago I decided that Eros should be my settlement. As you have said, Richard, it necessitated the pulling of many strings. Eros More than that, though—" Pop lifted his face to the skies, now blue with hazy morning. There was something terribly bright and proud in his eyes. "More than that, there is the desire to carve a home out of the wilderness. To be able to one day say, 'Here is my home that I have molded into beauty with my own hands.' Do you know what I mean, son? it's fine and warm, just as the report said. Moira, while Mom and Eleanor are fixing breakfast, suppose you lay out our blankets and spare clothing to dry? Grampaw, get a fire going. Pop and Bobby and I will get some wood." Four Eros days—the equivalent of forty-two Earth hours or so—had family were waiting now for Dick to return. Pop said seriously, "I'm afraid you'll have to eat them and like them for a little while, Father. We can't get fresh foods until we're settled we can't settle until—Ah! Here comes Dick!" though. Some tools, guns, wire—stuff like that." "How about the hypatomic?" "Let him eat, Rob," said Mom. "He's hungry." "I can eat and talk at the same time, Mom. I think I can get the hypatomic out. I'd better, anyhow. If we're ever going to raise the ship, we'll need power. And atomic power is the only kind we can get in this wilderness." And he shook his head. "But we can't do it in a day or a week. It will take time." "Time," said Pop easily, "is the one commodity with which we are over-supplied." He thought for a minute. "If that's the way it is, we might as well move." "Move?" demanded Grampaw. "What's the matter with the place we're at?" "For one thing, it's too exposed. An open beach is no place for a permanent habitation. So far we've been very lucky. We've had no storms. But for a permanent camp-site, we must select a spot further inland. A fertile place, where we can start crops. A place with fresh, running water, natural shelter against cold and wind and rain—" "What'll we do?" grinned Dick. "Flip a coin?" "No. Happily, there is a spot like that within an easy walk of here. Pop?" "We'll find out. Will this place you speak of be close enough to let me continue working on the
