Jon was watching them in his screen. "Yes, I see now. What causes it?"

"I don't know," Jak answered sadly and absently. "But I sure want to

know. How's about covering me while I go out and see if I can get one?"

"Well, maybe in your suit you'd be safe."

Once suited up, Jak went outside and across the short distance to where

the balls seems to be slightly closer together. He tried first one way

and then another to catch one, but at his lightest touch they burst

and deflated. After several unsuccessful attempts, though, he called

excitedly through his suit-sender.

"Jon, you read me?"

"Coming through."

"I'm going to try fanning one toward the air-analyzer. I want to see if

we can get an idea of what's inside. I've got a screwy hunch."

"Right, I'll switch the light away from them, up into the air."

Carefully Jak herded one of the globes near the ship, and was finally

successful in getting it close to the hull-vent of the air-analyzer.

When it was almost touching the ship's side, he reached out and touched

it, and it promptly broke.

"Get anything?" he yelled.

"Yes, gas of some sort. Taking the reading now. It seems to be mostly

nitrogen."

"Hah, that's it, then! I'm coming in."

When Jak was back inside, Jon helped him remove his helmet, then

demanded curiously, "What's it all about, Owl?"

"I'm not positive, of course, but I bet those things take the place of

bees for pollinating, and also furnish the fertilizer for the ground

when they burst and their nitrogen gets into the soil some way."

Later that evening Jon Carver sat for nearly an hour, studying intently

from one of his reelbooks, and the frown on his face grew deeper and

deeper.

Jak had been working over their father. He had given him a careful

sponge bath, then fed him another intravenous dosage of the combined

liquid protein, salt, sugar and glucose. Even though their mother had

been able to spoon-feed her husband small amounts of food each day, the

young hoped-to-be doctor felt additional nourishment was necessary.

When he finished his task and started to seek a comfortable seat in the

living quarters of the space yacht, to relax with a little reading of

his own, he noticed his brother's intent look and worried face.

"What's the matter, Jon?"

"Eh?" The younger boy looked up, startled, from his deep study. Then,

as Jak repeated the question, he answered unhappily, "I just don't know

enough, Owl. I can't figure out why Pop found such strong spectroscopic

lines of that new element while we were billions of miles away, and

yet we can't find any traces of it anywhere on these planets, except

what we found in that cache."

"Maybe it's in the sun."

"I tried that when we were out there, but 'Annie' didn't even peep."

The elder brother studied the problem a moment.

"Could it be so strong that even the little bit we found would have

shown those lines?"

"Maybe," doubtfully, "but I don't think so. Tomorrow morning, when the

sun comes up, I'm going to try to take a new reading from here. I tried

to read Two, but couldn't get anything. However, I'm not so hot with

the regular spectrograph, and that's why I'm boning up on it."

"Is this important?" Their mother had laid her sewing in her lap to

listen to them, trying to follow and understand what her sons were

talking about.

"Pop thought it was, Mom," Jon explained. "One of the things men have

been looking for ever since they first started dreaming of rockets and

spaceships, was the best possible fuel. We knew the one we're using now

isn't the ultimate, but it's the best they've been able to get so far.

Pop thought perhaps this new stuff might be it--_if_ we could find it,

and _if_ we could learn how to use it."

"Why can't we use it if you find it?" Jak wanted to know.

"There are so many problems. Maybe it would be so radioactive we

wouldn't be able to handle it or keep it in the storage bins without

endangering the people on the ship. Maybe the exciters and convertors

wouldn't handle it without a lot of new experimenting and new designs

we wouldn't have the scientific or technical know-how to make. Or it

might be that instead of getting a steady stream of power as we do with

our present activated-copper fuel, the stuff would want to blow up all

at once. If the metal's as powerful as I think it is, it might cause

an explosion that would make man's biggest H- or C-bomb look like a

firecracker."

"Then don't you go experimenting with it and blow us all up," his

mother said sharply.

Jon grinned at her. "You needn't worry about that, Mom, now that I've

had a chance to learn how little I know. Although I would've gone off

half-cocked that day you stopped me--for which I'm grateful, even

though I was sore at you for a while then. But I'm sure going to study

it as soon as we get the other markers set and can get back to Two."

"By that time Father will be well again," Jak said.

"Isn't it wonderful that he really is coming around all right? Seems to

be taking an awful long time for him to recover fully, though."

"I'm sure he'll be his own keen self again soon ... although he'll have

to stay in bed until that leg is strong enough to stand on again."

"Well, let's hit the sack, so we can get a good start in the morning.

'Night, Mom."

* * * * *

During their journeys over the surface of Planet Three the boys

conscientiously tended the machines and recorders that gave them the

data on land and water conditions, the proportions of each, the

approximate amounts of metallic ores their analyzers showed, the

information on weather, temperature and humidity. They took numerous

pictures as required by law--their mother often helping in this, after

Jak had taught her how to operate the cameras. These pictures Jak

developed and printed as he had time, and mounted them in their data

book for the Colonial Board to study when they got back. They also

mapped and recorded the size and distances of Three's two moons.

Jak named these "Zinnia" and "Begonia," much to Jon's sarcastic and

openly-expressed derision.

"This'll make a swell home for people who like cold weather." Jak tried

to change the subject.

"Yes, just as Two will for those who like it hotter." Jon's eyes shone.

"Pop sure picked a winner when he decided to explore this system. Even

with just these two worlds he has a prize."

"_If_ they accept our work as proof. Wonder what the fourth planet will

be like?" Jak continued in a different tone.

"Cold. Lots colder, probably, than Mars."

"Then it won't do us any good?"

"Depends on what's on it in the way of metals that can be mined. Maybe

we'll find something there. Might be natural gems or jewels, too."

"And anyway, cold never stopped man."

"That's right," Jon said admiringly. "They have mines on Pluto,

even--although they're mostly worked by automatics while the men stay

warm in their bubble-cities."

As the _Star Rover_ approached closer to the distant, smaller planet

they had named "Jon," their instruments showed it to have a diameter

of about 4400 miles, and a density of about 4.6, a little lighter than

Terra. This meant the gravity would be a bit weaker, and they would

weigh less than on their home planet. Four was almost a quarter of a

billion miles from the sun, and would be very cold, as Jon had said.

While their ship drove in closer, the boys' mother came into the

control room. All three Carvers stared excitedly into their visiplates,

watching their rapid approach to this new world. Would they find

anything of value there, or was it simply a barren wasteland of ice

and frozen air and rocks, far too cold and forbidding for men even to

bother trying to explore it?

When Jak, eyes still glued to the telescopic sights of his

spectro-analyzer, voiced something of this, Jon drawled, "You know

better than that, Owl. We said just yesterday that there's no place, no

matter how bad, that man won't explore to see if there's anything he

can possibly use. They'll follow us here, don't worry."

After cruising about the surface for some time, recording their data

and taking the needed pictures, they saw a fairly level valley,

ice-covered and bare, and Jon set the ship down there. By now he was

becoming an expert astrogator and pilot, and with his new controls they

could hardly feel the jar of the ship's landing.

"How's the temp outside?"

Jak was examining the gauges. "About a hundred below, and not a bit of

moisture, naturally. Going to try going out?"

"I don't...." their mother started to speak against it, but made

herself stop. Her boys were showing such resourcefulness and unexpected

habits of caution that she felt she must let them decide things for

themselves, even though her motherly instinct was always to hold them

back from possible dangers.

"Sure we're going out for a bit," Jon answered his brother, then

faced their mother. "It'll be all OK, Mom," he said affectionately.

"We'll wear our suits, of course, with the heaters on. We won't go

far, because the moment we feel any cold we'll run back. But I want to

see what it's like out there, and if there's any sort of life. We're

supposed to report...."

"Life? Here?" incredulously.

It was Jak who answered this. "Sure, Mother, there can be life-forms

anywhere. Oh, not necessarily nor even probably anything we know on

Terra. But there should be some sort of moss or lichen in the plant

line."

"Yes, it has been learned from experience there's some sort of life

almost everywhere," Jon chimed in.

"Even though most of it's so different from the basic protoplasm-type

we're used to that it's hard to realize it's really life at all," Jak

continued. "But then, remember back on Terra, the vast difference

between animal and vegetable life--so totally unlike each other. I

second Jon's plan to go out. I'd really like to see what's out there."

She sighed as if in recognition of the fact that these boys of hers

were fast becoming reliable, self-sufficient men. They were not her

babies any more. She was proud, of course--but she couldn't resist the

motherly impulse to warn, "Well, be careful, anyway."

"Sure, we will."

Jon locked all the controls in neutral, and the two boys went to put on

their suits. Knowing, as they did, the vital necessity of making sure

they were "tight" and fully equipped, they examined and inspected their

own and each other's spacesuits carefully before they opened the inner

lockdoor.

Once outside, they stood on the icy ground for several minutes to

make sure their heaters were working capably enough to keep them--and

especially their feet--warm. Finding they were as completely

comfortable as anyone ever can be inside that sort of a suit, they

started off across the frozen plain, headed for the near-distant hills

on the side of the valley closest to the ship.

Jak examined the ground about them intently as they walked, hoping

to find some sort of plant life, while Jon kept his eyes mostly on

the portable analyzer he carried, hoping they might discover valuable

deposits of inorganics. Was there any of that unknown fuel-metal here,

he wondered anxiously. Their big analyzer had not shown it as they were

coming in on the survey or landing spiral, but that did not necessarily

mean the portable wouldn't show it on closer approach, or that there

might not be some on a portion of the surface they had not yet covered

from above.

Their trips about and above the surface had, however, shown traces

of iron, manganese, gold, silver, copper and several other metals,

although not strongly enough to indicate great deposits. But Jon knew

experience had shown over the years that one of the inefficiencies of

such analyzers was that they would not show the _depth_ of a deposit.

Many times, when only a slight trace had been detected while flying

above the surface, prospectors on the ground had found veritable

bonanzas, once they started mining.

Even though the gravity was about eight per cent lighter than on Terra,

the boys found walking not too easy. The terrain was mostly rough,

although there were many spots of slick, glare ice. Too, there were

many hillocks, and cracks and crevasses between the slippery places.

So, even though they had added caulks to their metallic suit-boots,

walking was unsafe and hard. By the time they reached the base of the

first low hills they were winded and glad to rest a few minutes.

"Not a thing so far," Jak panted into his suit-mike. "I can't see even

a bit of color--just this white glare."

"'Annie' hasn't let out a peep, either. Guess this is a dead 'un all

right."

"At least this district looks it."

"Let's climb a ways, and if we don't find anything there, go back to

the ship and try somewhere else."

"I'll buy a chunk of that."

They started up the hill before them. The climbing was difficult

because of the ice and because in most places the side of the hill was

not a gradual slope, but a starkly steep climb. It was evident there

had been no gradual "weathering" here, to produce rounded edges and

rolling slopes, although there were occasional smooth places. These,

though, the boys knew could not be climbed at all without special

equipment which they did not carry.

"This isn't frozen-water ice, is it?" Jon asked as they panted upward.

"No, silly. There can be no water vapor here, any more than there is on

Neptune or Pluto back home. This is mostly frozen carbon dioxide."

"Well, it's just as cold and just as hard to climb as polar ice."

They climbed the quarter mile to the crest of the first hill and

peered eagerly over its top. In front and slightly below was another

valley--not as deep as the one in which their ship lay, but even

larger. From their higher position the floor of this new valley seemed

quite smooth.

"But that can be just an optical illusion," Jak answered Jon's

statement, adding, "the glare of white would make it look smoother from

a height."

Jon ignored the tone of superiority. "Good thing our suits have tinted

lenses. Do we go down?"

"Natch." Jak had already started. "Off there to the right and part way

down are some darker places. I want to look at them."

"Could lichens grow here?"

"Some could, possibly, though not exactly like the kind we'd find on

Earth. If there's life here, it's probably a type that can convert

energy directly from the elements in the ground or ice, instead of

using photo-synthesis or other methods of obtaining nourishment we know

about."

Half-sliding, half-climbing, they made their difficult way to the

little patch of gray-greenness, which Jak examined with growing delight.

"Hey, that's gneiss."

"What's nice about ... Oh!" Jon grew red-faced at having been caught

that way. "You and your education!" he snorted.

"See how brittle it is," Jak ignored the interruption as he touched a

stem, only to have it snap off like a slim glass fibre. "Can't tell

without a more thorough microscopic examination, but I'll bet this is

some sort of silicon-based life--crystalline instead of being like the

gneissic rocks back home."

Jon, meanwhile, had been surveying the valley with his binoculars.

Suddenly he gave a gasp, and focussed his glasses more steadily on

something that had caught his eye.

For some minutes he studied it, then called excitedly, "Hey, Owl, give

a look over there. See, beside that spire of rock," he pointed as

his brother rose and unlimbered his own pair of binoculars. "There's

movement of some sort there, though it's very, very slow, on that sort

of pyramid a yard or so high."

For long moments the two studied the spot through their high-powered

glasses, then Jak said slowly but with mounting excitement, "I think

you're right, Chubby, and that we've got to see."

In their excitement, the two started off faster and more carelessly

than was safe. They found out that fact when both, almost at the same

time, lost their footing and fell, coasting down the remainder of

the hill. Faster and faster they slid, shaken and becoming bruised,

although luckily neither broke any bones.

At the bottom they picked themselves up and started on again. Both

walked more gingerly now, and Jak limped a bit from a twisted ankle.

Yet they were so eager to see what this strange movement might be, they

soon forgot their bruises and hurried once more.

It was a good half mile across the valley floor to their destination.

But there, sure enough, they found _life_!

Strange, unearthly life it was, but they soon discovered that it

had reproduction, growth and movement--the three main criteria of

life-forms.

"Crystalline, by golly!" Jon yelled.

Jak was squatting beside the growing thing. It was somewhat pyramidal,

yet the sides were not smooth. Rather, they were many-faceted, like

the pieces of rock crystal with which the boys were familiar. It was a

grayish-white color--with just enough of the gray in it so it had been

visible from a distance, against the white background. But now, as the

boys were on the sunward side of one of the pyramids, for there were

many of them about, they could see that the light reflected from it was

kaleidoscopic coloration at times.

Jak reached out a gloved hand and rapped on the pyramid ... and it gave

forth a tinkling sound, then collapsed into a thousand tiny shards.

"You ... you broke it."

"Yes, I'm sorry. I didn't mean to kill it. Had no idea it was so

fragile." Jak rose, moved over to another pyramid, and squatted beside

it, examining it closely, but careful not to touch it. Jon sank onto

his heels beside him.

For a few seconds as they watched there was no change. But suddenly

they heard a small, clear _ping_, and a new crystal sprang into

existence near the base. Almost at once there was a repetition of

the sound and another appeared further up on the adjoining side of

the structure--or creature. As the boys continued watching this

was repeated over and over--with each tiny sound a new facet came

into being somewhere on the pyramid. Before their very eyes the

crystal-being was growing.

"Boy, that's something!" Jon exclaimed admiringly.

"Yes, it's a life-form, all right," Jak said more seriously, without

taking his eyes from it. "It's all new to us, but I'll bet there's

silicon of some sort beneath this carbon-dioxide ice, and that this

thing gets its nourishment from that."

"What makes it keep growing?"

"What makes a man or an animal or plant grow when it eats?"

"Oh!" Then, "Do you suppose it has any mentality?"

Jak was silent a moment, mulling that over. Then he looked at his

brother, a crease of concentration on his forehead. "I feel quite sure

that it probably has, but of a sort we wouldn't be able to understand,

even if we could get in contact with its so-called 'mind.' Even reading

that, I doubt very much if we'd be able to understand its way of

thinking, reasoning, or the motivations by which it lives." He went

back to studying the strange crystallization.

"_Ummm_, probably you're right," Jon agreed after some thought. A

moment later he asked, "Is it good for anything? I mean, can man use it

for something?"

Jak wrenched his gaze away from that astounding growth to look up in

shocked disgust. "Is that all you think about in the face of such a

marvel as this--whether it's worth anything or not? Here we've found an

entirely new type of life, and...."

"Hey, keep your suit tight, Owl. We have to report this, you know, and

I'm just trying to find out what to write down."

"Oh!" Jak spoke slowly, his voice now admitting the lightness of

that point of view. "I can't, offhand, see any practical value,

especially considering how easily these crystals are broken. But I

know geologists--and possibly chemists--will be intensely interested

in studying them. There's a lot they can learn here, I'm sure. We'll

naturally report all that, you're right, and the location of this

valley."

"Think they may occur all over the planet?"

"No telling, but probably if they can find the right sort of soil

nourishment. We didn't see any while coming down, but they might've

been there and we missed them, not expecting anything like this."

"We didn't see any other life-forms, either, that we could recognize.

Maybe these're the dominant species here."

Jak rose to his feet and looked all about him. There were hundreds of

the pyramids to be seen, some towering a dozen or more feet high and

as large across each base line; others very small--babies, he thought

with a grin.

Again he watched one of the smaller ones intently, noticing how it

grew. Jon walked about, looking at the different structures of that

mysterious, growing crystal.

Suddenly he stiffened, straining, listening. Then he called, "Hey, Jak,

you hear anything?"

"Huh?" his brother tore his gaze from the crystallization he was

watching. "Hear what?"

"Turn up the power of your suit receiver. There. There it is again....

Hey, sounds like our siren!"

"Yes, I heard it then. Mother must be in trouble, or something."

Jak's last words were flung back across his shoulder as he ran as fast

as he could across the icy wastes of the valley floor. Nor was Jon far

behind. In fact, after a few strides the younger, but longer-legged boy

was beside him, then forged ahead.

"Hurry, Owl! Mom wouldn't signal unless it was urgent."

"Maybe Father's worse."

They tried to conserve their breath after that for running and

climbing. Once Jon broke the silence. "Turn your oxygen a little

higher, Jak," he said as he twisted the small lever at his own shoulder

to increase the flow of the strength-giving energy.

They were panting and winded by the time they reached the top of the

hill. But they disregarded fatigue in the face of their mother's

probable danger--or their father's.

Jon looked quickly to one side and then the other. As Jak topped the

ridge he saw his brother run some twenty feet or so to where he had

spotted a fairly smooth downward slope. Down this the younger boy

launched himself feet first, sliding on his suit's back. Jak instantly

realized the reason, and threw himself after his brother.

In less than a tenth of the time it would have taken them to climb

down, the boys were at the foot of the hill. They struggled to their

feet and started off toward the ship. Both were again shaken and

sorely bruised from their rough slide, but they trotted on. Mother had

called--nothing else mattered.

As they came closer to the ship they saw her reason for summoning them.

All about the outer lockdoor were those strange crystalline structures,

growing swiftly. As the two boys came still closer, they could see that

streamers of the crystals had already reached the lower edge and were

trying to force their way through the almost imperceptible crack.

"They'll never get ... through there," Jon panted as he raced the last

few feet.

"Don't see ... how they can ... but watch 'em." Jak waded into the

alien, growing things. His gloved fists smashed right and left as he

spoke. Jon was already doing the same.

But whether these crystal-beings were of a different type from those

that Jak had broken in the distant valley, or just what was the reason,

the boys now found it more difficult to break these crystals down.

"These aren't ... like those ... back there." Jon had now seen that

these crystals did not always grow in pyramidal shape.

"No, they grow ... new crystals ... wherever needed." Jak had been

concentrating on the tendrils, or chains of crystals that were

reaching, always reaching, toward the lockdoor, while Jon had been

trying to break the bases of the pyramids from which these arms sprang.

Although the crystals were still fairly easy to break--especially the

tentacles, which were only a thin string--new ones replaced them so

swiftly, and their numbers increased so constantly, that it seemed

almost a losing battle.

"These're growing lots faster than the others." Jon gritted his teeth

as he now tried crushing the bases with his heavy metallic boots,

hoping thus to make it harder for the crystal-beings to reach the door.

For minutes the two boys fought in desperation; then Jon grunted in

disgust at his thoughtlessness, and yanked out his flame-gun. "Never

thought of this," he yelled as he trained it on the crystal-beings. The

terrifically hot flame washed off them in coruscating showers--but did

no damage.

"Try bullets," Jak unlimbered his gun from his back, and started firing

it into the base of the crystals nearest the lockdoor.

The heavy bullets shattered the crystals easily, and soon the boys

could begin to see that they were clearing the way.

"You keep firing while I open the door and climb in," Jon yelled.

"Then you climb in while I'm going to the control room and I'll lift

ship."

"Right," Jak replied and fired even faster as Jon touched the outer

mechanism-stud that opened the lock.

Hardly had it begun opening, however, than they heard the sound of

another gun being fired through the opening. They looked up in surprise

and saw it was their mother, shooting a shotgun. Jon scrambled up into

the lock.

"Good work, Mom, but get back in. I'm lifting ship."

He dashed through the inner doorway and into the control room. He threw

the switch and _Star Rover_ shuddered as its tubes roared into life.

Jon punched on the intercom visiplate that scanned the interior of the

lock, and saw his mother pulling Jak into the ship, then closing the

outer door. Quickly Jon put the ship into a slow cruising orbit and

switched on the auto-pilot. Remembering the open doors and the bitter

outside cold, he glanced to see that the automatic heaters were taking

care of the inside temperature, then ran back toward the lock.

There he found his brother desperately trying to warm their mother's

unsuited body, now growing blue from that terrible cold.

"Help me carry her into bed." Jak rose and grasped her arms, but Jon

pushed him aside. Stooping, he picked her up bodily. He ran, staggering

a bit, with her into the bunkroom. Jak was right behind, and pulled

some extra blankets from a drawer. Then, while he was piling covers

about her, Jon dashed into the galley.

He drew hot water from the tap and quickly made a cupful of instant

tea, then ran back with it to the bunkroom.

Some minutes later they saw with satisfaction that their mother's color

was growing more natural, and her body tremors were slowing from the

combined warmth of the extra blankets and hot drink. Only then did the

boys stop to help each other out of their suits.

"Thanks for the help, Mother, but don't you know enough to wear a suit

in weather as cold as this?" Jak's worry made his voice sharp.

"Yes, who's always fussing about us being careful?" Jon added. "Then

pull a stunt like this."

Their mother looked up at them, and the old impish grin they had seen

so seldom of late came onto her face.

"You've got me, Chums," she drawled. "From now on I reckon I'll keep my

big mouth shut."

Jon howled, and Jak added in the same sort of drawl, "Well, now, I

wouldn't go for to say it was 'big,'" and ducked as she slapped out at

him.

Soon the two boys sobered down. "We'd better go examine the lock and

make sure no crystals got in," Jak said.

"Yow, I forgot about that!" Jon sprang forward. "We sure don't want any

of them in or on the ship."

9

Despite Jon's desire to get away from this unfriendly world that bore

his name, he was careful to see that the signal-marker was set out and

functioning, and that the ship's log contained as complete a record

of the resources and data on the planet as was required by the Terran

Colonial Board. The same was true of Four's four moons. Jak checked

all the work, nor did they leave Four until both boys were satisfied

it was complete. Their mother was a great help in taking the numerous

photographs needed, having become quite competent in handling the

cameras. She was so relieved at the steady progress of her husband's

convalescence that she put extra enthusiasm into her photography. The

family still felt that Mr. Carver should be kept as quiet as possible

and away from any mental strain in connection with the ship and the

planet mapping and, in his weakness, he seemed content to leave it

that way for the time being. He asked few questions and accepted the

reassuring answers contentedly.

Nor, even though Jon wished to get back to friendly Two as soon as he

could, did he forget they still had to visit Planet Five, and scout and

record that.

So, as soon as they were completely done on Four, he lost no time

setting course for Five. Once on the way, he announced his names for

the four moons of Four, and now it was Jak's turn to scoff.

"Well, if you can name yours after flowers, I don't see why you've got

any kick coming because I name mine after fish," Jon asserted. "I leave

it to you, Mom--aren't Tuna, Betta, Sturgeon and Porpoise nice names?"

"I think they are fine, just as I think Zinnia and Begonia are aptly

named," she said diplomatically.

The two boys made faces at each other, then Jon turned back to his

computations. "I'm not as good at figuring these things out as Pop

is, but I think Five is about a half billion miles from the sun. It's

almost three hundred and fifty million miles from here, since it's

further around the sun. But we'll cut across on a direct route."

To his surprise, Jak came up and clapped him on the shoulder. "You're

doing a grand job of astrogating, Chubby. I'm really proud of you." His

voice was sincere and appreciative.

"Yes," their mother came over and kissed Jon, rumpling his hair

affectionately. "I've been unexpectedly relieved that you've managed to

get us to each world so surely and to land us so gently. Though maybe

I shouldn't have been so surprised, at that." She laughed gaily as her

younger son flushed from this unexpected praise.

"Aw, you guys are just saying that because I'm so wonderful." Jon

tried to joke, but they could tell how deeply he felt their compliments.

* * * * *

A day later, when Jon announced they were approaching this outermost

planet, the other two joined him in the control room, and all were soon

deeply engrossed in the sight revealed to them in their visiplates.

An hour or so later Jon was examining their spectro-analyzer, when he

let out a yelp of excitement. "Hey, that fuel-stuff's showing up. It

must've come from Five." And a moment later, "Listen to 'Annie' rattle.

It sure is there--but plenty."

They clustered about him, and even though they could not tell anything

from the lines on the spectrograph that he pointed out, they could hear

the machine chattering, and they grew excited from his exultation.

"Miners can use the same type of automatics they use on Pluto to get

it, can't they?" Jak asked.

"I'd imagine so, although I really don't know anything about it.

However, if we find we can use it, there's where they can get it, and

that's the important thing."

Their plates again showed only the blinding whiteness of ice they knew

was frozen carbon dioxide rather than frozen water or snow. For even

more than on Four, there could be no water here, even in its most

frozen form.

They cruised about above the surface, watching their instruments to

find and record any metallic ore deposits, especially the new one. The

terrain was so forbidding, so desolate, that even the irrepressible Jon

felt no desire to land on it, or to go outside.

Again their mother took most of the needed photographs, while the

boys recorded all the other data of geography, size and conditions

generally. Finally, Jon set the ship down on a fairly level plateau

close to what they figured was the equator.

"Well, here we are and that's all I care about," Jon announced with a

shiver. "We'll use the distant hands to put out the marker. Then we'll

see if we can find the location of that fuel deposit."

Jak agreed. "I wouldn't go out there for a million credits." He

shuddered as he looked out the port while the others crowded about to

view that forbidding scene. "Maybe we should, but I sure wouldn't get

any fun out of it."

"Doubt if our suits would be able to keep us warm, even with the

heaters at max."

"No," their mother said sharply, although they could detect the relief

in her voice that they had already made the decision. "This is one time

I would have set my foot down, and not allowed it. This place gives me

the creeps."

While Jon was making up the tape, Jak carried a signal-sender into

the lock and placed it beneath those "distant hands." Jon came in and

installed the tape, then started the mechanism running.

They returned to the control room, and Jak, whistling unmelodiously

between his teeth, operated the controls that opened the outer door,

then used the lifting servo-mechanism to set the signal-sender outside

on the icy ground. When the outer door was closed, he nodded to Jon and

the latter lifted the ship again.

"I'm going up a couple of miles, then circle about to look for deposits

of that fuel metal. Meanwhile, as we go we can get the rest of our

dope, and then scoot out of here."

Jak again took his place at the recorders, while his mother was at

the cameras. Jon set the ship into a quartering circle, and when he

had located the direction in which the analyzer showed the strongest

indications of the enigmatic metal, swung into that course.

They had gone less than five hundred miles when they noticed a reddish

glow in the distance. As they came closer, they saw that ahead and

below was a terrific, whirling mass of colored gas.

"Wow, look at that storm!" Jak yelled. But he could not help adding,

"Did you ever see anything more beautiful?"

"Better get well above it, hadn't you?" Mrs. Carver asked anxiously.

"It looks dangerous."

"I'm sure not going through it." Jon was already lifting the ship. "But

'Annie' says the stuffs right close."

At five miles high he leveled off and put the ship into a narrowing

spiral. From that vantage point they could see that the storm was a

purely localized affair, perhaps some twenty miles in diameter.

"Wonder what makes those colors?" Jak called from the

telescopic-visiplate into which he was staring.

"Suppose it could be a volcano?"

"Could there be volcanic action on so cold a planet?" their mother

asked in astonishment.

"I don't see how there could be," Jak answered slowly, "but that

certainly looks like flames of some sort down there."

"Maybe the experts from Terra can figure it out from our color

pictures," Mrs. Carver said. "I'm taking a lot of extra ones, with the

variable focus lens."

"That new metal's down there, though, whatever it is. Since those other

people mined it, our miners'll figure out how to get it, too, I'll bet."

"I wonder." Jak was suddenly diffident. "Don't laugh now, but do you

suppose maybe those flames could be some sort of life, and that they're

feeding on the metal, which you said was highly radioactive?"

"Now who's nutty?" Jon asked witheringly, while Mrs. Carver gasped at

the daring concept.

"Well, some of those flames are coming higher and aiming for us." Jak

tried to defend his position. "We'd have said such crystal-creatures as

we found on Four were impossible, but we know they aren't and that they

have some sort of--well, intelligence, from the way they tried to get

our ship. So why not flame-beings?"

"Do you think they're dangerous?" Their mother's voice held a

frightened note as she saw in her plate those swiftly approaching

flames.

"Don't see how they could possibly hurt the ship, or us." Jon tried to

speak calmly ... but he tilted the nose and the space-yacht was soon

nearly ten miles high, although it still continued circling.

"Man, oh man, they're certainly beautiful!" Jak was enthralled as those

bright, shining tongues of flame grew taller and taller. "There ...

there does seem to be a ... a purpose in the way they act, though."

His tone changed to a more anxious one.

The flames were now high above the storm of fire that constituted the

main ... body? Now these tongues broke loose, and as they continued

rising toward the ship they became more spherical in shape--were no

longer simply extensions of the planet-based fires. And as they rose

ever higher and faster, they seemed to the anxious watchers to be

really thinking, intelligent entities.

"Let's move away from here," their mother pleaded. "I'm getting the

feeling that they are actually pursuing us--and for no good purpose,

either."

Jon touched the controls, and the ship began rising more swiftly.

"No, don't leave; I want to study ..." Jak began, but Jon interrupted

him.

"So would I like to know more about them, but if Mom wants to leave,

away we go." Yet there was an undercurrent of relief in his voice.

But as if guessing his intention, the flames hurtled after them at such

tremendous speed that before the ship had barely begun accelerating,

they were almost up to it.

"Hang on tight!" Jon yelled, and increased the acceleration. Soon the

ship had left the flames behind. Peering in their telescopic plates,

the three could see the flames, reluctantly and as if baffled, return

at last to their home below.

"All gone, Mother. We're safe now," Jak said comfortingly.

"Thank you, God," she said devoutly and sank limply into a seat. "I was

afraid for awhile...."

"So was I," Jon's teeth began chattering and his body shaking so hard

that he, too, was glad he was sitting down. Now that it was all over

the shock of that strangeness--that utter alienness--was hitting him.

Nor was Jak in much better shape, in spite of his expressed desire to

stay and study the enigmatic flame-life.

It was many minutes before the trio were able to discuss the matter

calmly, and to realize they had been in actual danger.

"I see now we sure would have been, if Jon hadn't zoomed us out of

there so fast," Jak said.

Finally, Mrs. Carver shook herself. "I'll go get lunch. It must be

time, hungry as I feel."

"Me, too," Jon laughed. "But then, I'm always hungry."

As soon as the three had finished eating, Mrs. Carver and Jak went

to sit with the invalid and watch hopefully for those semi-conscious

moments which were becoming more and more frequent. Jon went back to

check his course back to Planet Two, and to lounge later in the pilot's

seat, studying from one of his reelbooks.

"There must be," he told himself, "some way of handling that fuel, and

of storing and using it. The fact that it was cached there on Two shows

that. But then, those folks who used it were so evidently far advanced

in science."

A bit later the thought intruded, "Hey, if that stuff's so powerful

now, after all the untold time it was stored there, what was it like

when it was new?"

An hour or so later he heard his name called, urgently. He sprang up

and ran into the other room, to see his brother beckoning him from the

doorway of their parents' bunkroom. As he came up Jon saw his mother

inside, bending over the bunk.

"Is--is Pop worse? He'd been so much better!" Jon's heart was clogging

his speech.

"No, he seems to be waking up fully." Jak turned a radiant face toward

him, then immediately knelt by his father's side.

Jon knelt, too, his eyes fastened on the still figure in the bed. But

even as he watched, the eyelids slowly fluttered a bit, then a hand was

raised to the forehead. Mr. Carver's head turned from side to side,

restlessly, and then his eyes opened. They seemed to be studying each

of the three watchers in turn, as well as the room in which he was

lying.

"What--" The voice was low, and they strained to hear, "What happened

to me?"

His wife answered quietly, "Don't you worry about that now, Dear. You

were hurt and have been unconscious for some time. But now you're

getting well, and I'll tell you all about it when you wake up again. Go

back to sleep now. You are getting stronger that way."

Mr. Carver seemed to be weighing that advice, then to accept it. "All

right," he said with an affectionate smile. He closed his eyes, and

soon the rhythmic breathing told the three anxious watchers he was

asleep once more.

Jon let out his breath in a happy sigh, there were tears of joy in his

mother's eyes. Jak exclaimed delightedly, "He's getting well, Mother!

In another day or so he'll be all right. Naturally he'd not remember

clearly for a while. My textreels say people with concussions seldom

do. But as soon as he gets a little stronger and those damaged places

in his brain completely restore themselves, he will, you'll see."

Jon chimed in quickly, although he was not too sure of what he was

saying. "It's just the shock, like Jak says. He'll snap out of it in a

day or so."

She wiped her eyes on the corner of her apron, and smiled tremulously,

"Of course, Boys. I ... I guess I've just been so nervous and--and he

was so much more like himself this time."

"No wonder," Jon laid his hand gently on her arm. "You've been under

a terrible strain, too, what with Pop sick and us boys roaming around

on alien planets. But we'll be back on Two where it's more like home,

and there's only a little more to be done before we can start back

for Terra. Anyway, we did and are doing what had to be done to prove

up Pop's claim, and we've beaten Slik Bogin, supposing he's out here

trying to cheat us out of this system."

The boys went into the control room. "We'll have to figure out where to

lay out our townsite, and which planet is best to put it on."

"I vote for Two," Jak said after only a moment's hesitation. "It seems

the most homelike to me, and we can stand the climate so much better

there. Won't have to work in suits all the time."

"Yes, that's where I wanted it, too. This is a funny system, in a way,

though--there's a much greater difference in the distances between the

planets than we usually find."

"Why's that?"

"Ask some astronomer, not me. Has something to do with sizes and

densities, I believe--but I'm not sure even of that. Maybe it's because

this sun is larger and denser than the others we've studied. I know

it's almost a quarter bigger than Sol."

"Two's almost as far away from this sun as Terra is from Sol, didn't

you say?"

"Yes, Earth's average is about ninety-three million miles, while Two

is about eighty-seven, which accounts for its warmth. Then, near as I

can figure it out, Three is lots closer than Mars, yet Five is only a

little further than Jupe, and Four is between them."

"Didn't I read somewhere that Sol's Asteroid Belt is really a broken-up

planet?"

"Some people think so. But nobody knows for sure, yet.

"All right, then, let's put our city on Two." Jak grinned. "Has the

mastermind decided where to put it?"

"Not the exact location." Jon flushed, but grinned back. "Colonial says

it must be fairly close to good water, good soil, forests, and mineral

deposits, however."

He sobered and looked at his brother appealingly. "Golly, Owl, any

chance of Pop getting entirely well before we have to start it, so that

it wouldn't hurt him to do brainwork? I don't know very much about city

planning, you know--only the specs Colonial furnished."

"He could--but maybe he won't. I don't know enough to say how soon.

I've been fooled before--thought it would only take a few days, when he

was first hurt."

"What about his being so ... so ... dreamy?"

"You mean, when he woke up just now? That's really nothing to worry

about, honestly, just as I told you and Mother. I looked it up again,

and the text says amnesiacs often act that way just before they recover

full consciousness."

Jon let out his breath in relief.

"But listen," Jak changed back to the old subject. "If you don't know

anything about city planning--and I don't either--how're we going to

know what has to be done to satisfy the Colonial Board?"

"It's all in the papers they gave us that have to be filled out to file

when we get back. It tells how much area to cover, how far apart the

streets are to be and how wide, and how to mark out everything."

"Gosh, that sounds like a complicated deal. It'll take us an awful long

time, won't it?"

"Not as much as you'd think. If we work really hard, I figure we should

be able to do it in a couple of weeks. We just have to sketch in the

bare outline, not fill it all in.

"Get out the papers, then, and we'll study them."

"Right!"

10

With the various members of the Carver family busy with their studies

and chores, it did not seem long before they came close to Planet Two,

and Jon laid down his reelbooks to begin preparing for the landing. He

had started down through the atmosphere when Jak suddenly roused.

"Why don't we circle around a bit and look for our townsite from the

air?"

"I was going to," Jon said with a disarming grin. "Just wanted to get

close enough to see well before I called you in to help me decide."

At about five miles above the surface he leveled off and began

circumnavigating the globe. He headed in the direction which--he

remembered from their previous visit--would soonest bring them near

the great ocean, but zigzagged from north to south as they proceeded

eastward.

"Watch for rivers," he said. "A fairly large one that empties into the

ocean."

They were about halfway between the north pole and the equator, as they

had already decided the climate in that latitude would probably be the

most suitably average. In a few minutes of traveling they saw ahead a

plain that looked to be just what they wanted.

Quickly Jon maneuvered the ship downward and soon landed. They were

just a few miles from the edge of the great ocean, at the mouth of

a large river of considerable width and length, and not far from an

extensive forest to the south, and a range of considerable mountains to

the west.

"Hope the soil here is good," Jon commented as he locked the controls

in neutral. "Everything else seems perfect."

"The spec-anal shows minerals fairly close, in those hills to the

west." Jak was eagerly peering from the port.

"I know--that's why I chose this spot. Nice flat land here; good river;

close to the ocean, mountains less than a hundred miles away, and not

too high. Ideal place, I'd say.

"That it is; that it is. Going out today?"

"Why not? Nearly four hours till sundown. We can start planning today,

then get busy in the morning."

Their mother came in just then. "I thought it felt like we had landed.

What are you going to do here?" She glanced out of the port.

"We have to lay out a townsite," Jon answered, and at her astonished

look he explained.

She shook her head admiringly and with surprise. "You boys continually

amaze me--you seem able to do anything."

Jon shrugged that off. "When a thing has to be done, a fellow usually

can figure out some way of doing it."

"Besides," Jak grinned, "we're like those old chaps on Terra who used

to say, 'The difficult we do immediately, the impossible takes a little

longer.'"

They left her then and hurried out of the ship. Even though they felt

there could be no possible danger here--they could see for miles in

every direction, and noticed nothing moving--they were wise enough from

experience to carry their rifles slung across their backs, and wore

bandoliers of ammunition. In addition, both carried tools and what

equipment they felt might be needed.

Once outside, they ran first to the river, and tested the water. It was

fresh and clear, and they knew this would be a good source of water for

their proposed city ... until men might pollute it with their garbage

and wastes.

"Got your pedometer?" Jak asked.

"Sure, right here in my coverall pocket. Why?"

"I suggest this would be a good place for the center of the town's

north side...."

"Yes, here by the riverbank would...."

"I'll go east and you go west a half mile each, then we'll set our

corner stakes."

"Then we'll both walk south a mile and set those, and have the four

corners done. Sometimes, Owl, I have to give you credit for having

brains."

"Wish I could say the same about you." Jak reached out and gave his

brother a friendly shove. "Get going, Stupe. And when we start south,

be sure you keep your line straight."

"Look who's yelping. Mine'll be as plumb as yours--probably more so,

because I'm a better plumber than you are."

Jon started his pacing, while Jak went in the opposite direction after

a pretended "_grrr_" at Jon's horrible pun.

When they returned to the ship, as the sun was going down, they felt

they had made a good beginning. But as they went into the control

room to talk alone, away from their mother's hearing--lest they worry

her--they were not too cheerful.

"You know anything about surveying?" Jak slumped into a seat.

"Nope, not a sardine's worth." Jon paced forth and back in the little

room. "That's what has me worried. How're we going to place those other

marking stakes in exactly the right spots."

"Guess we'll have to measure them some other way."

"How?"

"Darned if I know. You're the mechanically--minded one--I thought you

could figure it out."

Jon continued his pacing, his young forehead creased with thought.

Finally, just as their mother called them to dinner, he looked up

excitedly. "Hey, it'll be easy, after all!"

"How?" Jak was as excited as his brother as they went in to the living

quarters and sat down at the table.

"A light plastic line that won't stretch, exactly measured, and

fastened to two metal pin-stakes. We'll make two sets, and...."

"I get it. One the length of the blocks, the other the width of the

streets."

"Right. Stick a pin in the ground, measure out the line, then plant one

of our regular stakes."

"Then give a yank, pull the pin out and haul it in. Then use the other

set to measure the street...."

"Yes, just keep going. Hey, I believe with that system we could each

work alone, so I'll make two sets."

Jak thought all this over swiftly for several minutes, working fork and

knife and jaws meanwhile. Finally, between mouthfuls, he said slowly,

"I can't see a flaw in it--as long as we're mighty careful. Do you

think it'll pass inspection?"

"If we take our time and make sure we're right, I don't see why not."

"What're you boys talking about now?" Their mother set a refilled dish

of steaming Chlorella stew on the table, and resumed her own seat.

They explained, and told her the necessity of what they had to do

in order to prove up their father's claim on this system, when they

returned to Terra and appeared before the Colonial Board with their

proofs of prime discovery.

The worried look came back into her eyes. "I always understood that

surveying was a mighty exact profession. Do you really think you can

measure it exactly enough to take the place of a regular survey?"

"I think we can make it close enough so that when Pop wakes up and

shows us how to do the final survey with the instruments, we can save

a lot of time, at least," Jon assured her. "That's what we're thinking

and planning about now."

"You see, Mother," Jak broke in, "if we have the stakes all set, all

we'll have to do is to make the sights on each one, after Father

teaches us how to use the transit. Then, if we should be off anywhere,

we can fix them easily."

"Yes, it'll cut down the time a lot," Jon went on, "and now we're so

near done, I want to get everything finished so we can go back to Terra

immejit."

"Why? Getting homesick?" his mother teased.

"Not so much that, but we want to get our claim before the Board.

Anything can happen when such distances and time are concerned...."

"And we just don't want anything to spoil Father's chances of having

this valuable claim verified."

"I see." She smiled now in relief, and again her eyes showed the pride

she felt in her two manly boys who were daily proving themselves more

than equal to the unusual situations in which they found themselves.

"Your father woke up again while you were out, and...."

"He did?" It was a duet of happy excitement.

"... and while he still didn't seem to realize what had happened, he

acted even more as though he recognized me. He let me feed him some

broth, then went back to sleep again very contentedly."

"Golly, that's great!" Jon reached out and patted her hand.

The three chatted together with more freedom and animation than they

had known since the terrible accident first occurred. It seemed as

though their worst troubles were over. For Tad Carver was so reliable,

so confident in himself, so trust-inspiring--even beyond their natural

love for him--that they felt everything would just have to work out

right, once he was again in command.

As soon as they had finished eating, the boys hurried to the storeroom

and found some metal rods.

"Cut me four lengths about fifteen inches each," Jon ordered as he went

to the workbench. He cleared a space, then began getting the tools he

wanted, and hooking up the induction furnace.

"You'll need eight for two full sets, won't you?"

"I got to thinking we'd better make only one set for now. If it works

out all OK, then we can make the other."

By the time Jak had the pieces cut, Jon was ready to heat one end of

each in the furnace, then bend it into a small eye. The other end he

sharpened on the emery wheel.

"Now measure out pieces of that plastic rope," he ordered, pointing

to a reel of small-diametered but very strong line. "Figure about six

inches extra on each...."

"Look, Chum, you tend to your job and give me credit for brains enough

to know that much." Jak's tone was almost cross, for sometimes this

younger brother got on his nerves, since Jon did occasionally get quite

"bossy."

But the elder quickly subdued that feeling--helped by the surprised and

somewhat hurt look in Jon's eyes. He knew so well that Jon was merely

trying--as he himself was learning to do--to see that neither made any

mistakes in this important work they were attempting to do in their

father's absence. Father was always cautioning them to take pains with

whatever they were doing, and they usually accepted his warning and

advice--as they did their mother's--without any more grumbling than

boys ordinarily make about such "fussing."

But now each of them--and both of them together--had to be, and did

try to be, extra painstaking in all the things their father would

have cautioned them about, and they checked and rechecked each other

constantly. So Jak said nothing more, and quietly helped Jon complete

the stakes-and-line sets. After all, he admitted honestly, there were

undoubtedly times when he got just as "bossy" as Jon did.

Soon the two sets of pins and line were done. Each of the boys measured

each once--twice--to make doubly sure their work was right. Then they

cut up and sharpened a number of wooden stakes from some inch-by-inch

strips they found in the storeroom.

The next morning they started out early. Each carried a bundle of the

marking stakes, and Jon had a small sledge in one hand. In addition,

they had their rifles slung across their backs.

"Working together to begin with," Jon said at breakfast, "we can start

the eastward leg from the southwest corner, and run it a ways, then

come back and start the northward one from this same corner."

"Yes, if we get that first corner square and right, there's less chance

of the other three being wrong--they'll more or less check themselves."

They soon found they could work at quite a swift pace, and at lunch

time Jon cried, "At this rate we'll have time to go back and re-check

everything, and still get done within our two weeks."

"Yes, if we don't run into any trouble, this seems to be working out

fine. Much better than I'd have given you credit for being able to

figure out, Chubby."

"Catfish to you, Brother!" Jon grinned. "Hey, that reminds me. I want

to see if that river's got any fish in it--and no...." He caught

himself and stopped, but Jak knew what he meant. Their mother still

didn't know about that quicksand Jon had been almost trapped in, and

they didn't want her to learn of it.

"I suppose it would be worth knowing," Jak had hastened to say, almost

as if interrupting. "For once your eternal love of fishing will have

its good points--as well as getting us fresh food. What about the

ocean?"

"I'll try that, too, if I have time. Surf-fishing won't tell us too

much about the deeper sea, and I haven't any heavy tackle for anything

very big if we happen to run into it. But probably, close to shore like

I'll have to fish, we wouldn't catch anything my lines and hooks won't

handle."

"If _you_ can handle 'em," Jak said with a grin.

"Don't you worry about me," Jon retorted. "I can pull in anything I can

get my hook on."

"Except a sunken ship," Jak jibed, and Jon's face grew red. That

incident, when he and his father had been fishing off the coast of

Southern California, back in Terra's Pacific Ocean, was still a tender

subject with him. He had had to cut his line that time, because they

could not loosen his hooks, and he had lost a favorite spinner and

leader and half his best line.

That first week passed uneventfully. The boys worked hard, from shortly

after sunup to almost sundown. So hard, in fact, that their mother

finally protested after noticing that they were so weary that they

slumped in their chairs at the table and could hardly eat each evening

when they returned to the ship.

"Now you boys listen to your mother," she commanded one night at

dinner. "I'm just as anxious to get back to Earth as you are, but

there's no sense killing yourselves to save a day or two. From now on,

you are to start an hour later, and quit an hour earlier."

Jak managed a weak grin. "Guess you're right, Mother. But we are coming

along fine."

"Sure, we've almost completed outlining the site. We'll have to take

tomorrow off anyway, to go to the forest out there and cut some more

stakes," Jon added.

"It'll make a nice vacation. I'm really fed up with so much sameness of

hard work."

"Yes, it's been a steady grind, no fooling, but we wanted to get it

done as quick as we can, so Pop can check it."

For their father had been waking up several times every day, their

mother reported. True, he had only been conscious for short periods,

and was still too weak to be bothered with any of their problems. But,

she told the boys, he was able to eat something each time he awoke, and

his mind was clear again. She was preparing easily eaten and digested

foods that would bring back his strength quickly.

Jak asked anxiously whether his father had mentioned how the leg felt,

and Mrs. Carver told him, "He says it doesn't pain any, although

sometimes it itches beneath the cast."

Later on, just as they finished eating, Jak suggested, "Take your

tackle along tomorrow, Chubby, and we'll chop where the woods meet the

river."

"Why, t'anks, pal, you're a good kid." Jon made a fake pass at his

brother, who jumped up from the table and yanked the other's chair

backward, starting a small scuffle which their mother wisely did not

try to stop, knowing that, tired as they were, it would last only a few

seconds and would be good for them.

* * * * *

When the boys returned from their expedition the next night, with arms

and backs loaded with bundles of stakes, and Jon's creel well-filled

with Two's fish-things, she met them anxiously at the lockdoor.

"Did you boys hear or see the ship that passed over us this morning?"

"Ship?"

"No, we didn't see nor hear a thing. Sure it was a ship?"

"No, I didn't see it, either. I thought I heard one, and ran to look

out, but couldn't locate anything. Maybe it was just my imagination."

"Spaceship or airship?" Jon asked.

"I couldn't tell you that, either, except that if I did really hear

one, it must have been a spaceship to disappear so quickly."

"Unless it was a fast jet--they're just as hard to spot."

They discussed the affair for some time, but could come to no

conclusions. If it was a ship, why hadn't it stopped or signalled?

And if it wasn't one, what had she heard? Or had she actually heard

anything?

Two evenings later the two boys had completed outlining their city

site, and were just climbing into the _Star Rover_ when they heard

their mother's voice.

"That you, boys? Come in here. Hurry!"

At the urgency in her voice, they ran quickly and found her sitting at

the side of their father's bunk. As they got closer they saw his head

turn toward them, and recognition in the wide-open eyes.

"Hello, fellows!" His voice was weak but happy.

"Father!"

"Oh, Pop, you're awake at last!"

The two almost fought to be closest to him, but their mother moved a

little and both sank to their haunches beside the bunk, each with one

of their father's somewhat emaciated hands in theirs.

"Your mother tells me I've been sick quite a long time, and that you

chaps have been carrying on. I'm grateful, and proud."

"You should see the way Mom has caught on to doing things," Jon said

quickly. "She does almost all our photographing now."

"And Jon has developed into a real astrogator," Jak said.

"Yes, Pop, but you wouldn't be as well as you are today if it hadn't

been for Owl knowing how to set your leg and make a cast for it, and

giving you the proper medicines and intravenous feedings." Jon turned

to smile at his brother, who grew red in the face and tried to stop

the compliments, but the younger boy rushed on. "He's really a whiz as

a doctor. Knew exactly what to do for you. How's your leg feel?"

"Fine, thanks to you, Jak."

"Oh, it wasn't so much--and I didn't _know_. I had to study a lot to

find out...."

"Anyway, I'm still alive and that shows you did a fine job." Mr. Carver

lifted a weak hand to caress his elder son's face. Then he turned

toward Jon. "I've had fine reports of you, too, Son. Your mother

says...."

"Yes, if anyone deserves praise around here, it's Jon," Jak broke

in. "He has done all the piloting and figuring courses, and he even

invented a one-man control so he can land and take off without all the

trouble and preciseness needed before. Why, he...."

"Nix Owl!" Jon was the one to be embarrassed now. "That can wait until

Pop's stronger. The main thing is to report now, so he can tell us what

to do next."

"Where are we--and what has been done so far?" Mr. Carver asked. "Your

mother hasn't--or wouldn't--tell me, except that we've reached the new

system, and are landed on one of the worlds there."

"We're on Planet Two, and we're laying out the city site that the Board

requires. This sun has five planets, and Two and Three are perfectly

habitable for humans, but no natives above animal level," Jak began.

"There're seven moons--one at Two, two at Three, and four at Four,"

Jon took up the tale. "We've visited all the planets, and have set out

the automatic signal-senders, with tapes giving you the credit for the

prime discovery."

"They named the sun 'Carveria' after you, Mr. C." His wife leaned

forward, eyes shining with pride, and an arm across the shoulders of

each of the boys. "They named the planets after one of us, each, and

the fifth one after the ship, and we've given names to the moons, too."

"This world will be swell for people who like it warm, and Three will

be just as good for those who prefer colder weather. Both are a lot

like Terra at different seasons and sections, and both are rich in

soil, water, forests, metals and...."

"And we discovered a cache of that new fuel-metal you thought you saw

in the spectroscope," Jon broke in, his voice bubbling with eagerness.

"Right here on Two. Not a mine or a vein, understand, but a cache, in a

metal box buried in the sand. Must have been some people a long, long

time ago, because from the sand drifted inside the box it apparently

hadn't been touched for thousands of years. And it showed up on

Five...."

"But it's guarded by some sort of sentient flames," Jak burst in.

His father's face lighted up. "Have you tried it yet?" he asked Jon.

"No," The boy's face showed disappointment. "Mom wouldn't let me

take any chances when I first wanted to, but now I'm glad--it's very

highly radioactive still, in spite of who knows how many half-life

deteriorations. It might've blown us higher than up. Maybe, though,

when you get better we can study...."

"If we haven't got a small lead box, you ought to be able to make one,"

his father broke in. "You could probably handle a small quantity of

it that way, to bring it in so we can study it. Maybe, though," as an

afterthought, "if it's that strong, you'd better wait for me to help

before trying any of it in the generators."

"It's in little cubes, a bit smaller than our copper pellets. That's

why I'm so sure it's a fuel, and that it was put here by some sort of

people who had advanced space travel a long, long time ago." Jon was

still excited. "We figure all we have to do is finish laying out the

town here, and then we can start back for Terra and put your claim

before the Colonial Board," Jon said. "Of course, we all hoped and

expected you'd be well enough to check what we've done...."

"But we tried to follow all the items in the papers the Board gave us,"

Jak added seriously. "And now you're well, we can make sure...."

"You father is far from well yet," their mother broke in, her voice

imperative. "We are all so happy he's awake at last, but I can see he's

very weak and that all this excitement has been almost too much for

him. You boys say 'Good night' to him now, and then run off and eat

your dinner, and let him sleep. Tomorrow evening you can finish your

report."

Reluctantly the boys obeyed, and went into their living quarters and to

the table.

"Golly, I should think Pop'd want to hear all about it now." Jon

frowned with disappointment.

"He does, don't you worry," Jak tried to cheer him. "I should have

watched him more closely to see we didn't excite or overtire him, but

I was just as happy and eager as you were. He'll be stronger after

another good long sleep, but we've got to be careful not to expect too

much of him for some time yet."

"Yes, I know you're right." Then Jon's face lighted with relief. "But

it's sure swell to have him awake so we can talk to him and he can take

charge of things again. You did a grand job, Owl, bringing him through."

"That's another thing, you big bum. You go handing out praise like that

again, and I'll bust you one."

"Oh, yeh, and who was the parrotfish talking up so big the few little

things I did?"

Jak came over and threw his arm across the shoulders of his taller but

younger brother. "Both of us were so carried away by our enthusiasm we

forgot to belittle each other," he said sagely. "Maybe we do sort of

like each other, after all."

Jon pushed him away with rough tenderness, but his eyes were

suspiciously moist. His words, though, were an attempted snort, as he

picked up his knife and fork.

"What do you want--the next waltz?"

When the boys came into the dinette the next morning, their mother was

humming happily as she prepared breakfast, and greeted them with a

cheery smile.

"Pop awake yet?" Jon asked as he saw her mood.

"No, but he's sleeping so sweetly I know he's all right," she answered.

They sat down and began eating. After finishing, Jak said, "Well, we

might as well go out and work some more on our townsite."

"Call us when Pop wakes up, will you, please?" Jon took a last sip of

his juice-concentrate.

"That'd be silly." Jak frowned. "We know he can't come and help us, so

why should we run several miles back here when we can see him when we

get back?"

Jon opened his mouth to reply, his eyes flashing almost angrily, but

their mother interrupted quickly with a question, "Boys, just why do

you have to lay out such a site?"

"The Board requires it," Jon answered shortly.

"In the early days of exploration," Jak explained more patiently, "some

of the space crews used to make their reports after merely flying above

the surface of the planets of a new system. In fact, some of them

didn't even go that close, and merely made up sketchy reports."

"Then when colonists got there," Jon, who had simmered down by now,

took up the explanation, "they often found conditions very different,

and many times quite dangerous to them."

"Yes, sometimes there were even intelligent inhabitants who hadn't been

reported, so their planets couldn't be used for colonization. So the

Board made this new ruling," Jak continued. "Now we have to have so

many photos taken from various heights and at different places all over

the surface of each planet, and each moon more than one hundred miles

in diameter. And we have to lay out a townsite on the most Earthlike

planet, mostly to show we actually have been there and spent some time

there...."

"And it really doesn't make any difference whether the people who'll

come here to live use it or not...."

"But we think they will use ours because we selected a place close to a

river and the ocean, close to forests and fairly near minerals."

"Yes, you have done a wonderful job, I know that much about it."

"Well, we'll go out and re-check our lines," Jon said. "I've been

studying and experimenting with the theodolite, and I can...."

"What is that?" she asked.

"What's what? Oh, the 'theodolite'? That's the surveyor's telescope.

I've learned enough about it so I can tell if our lines have been run

straight, and as we were so careful in measuring the distances, I'm

quite sure they're fairly accurate."

"Yes," Jak chimed in, "I'll bet none of them are more than an inch off,

if that."

"Optimist," Jon scoffed. "I'd take that bet away from you, only it'd be

cheating an infant."

Jak started a retort, then thought better of it, and shut up.

They left the ship soon, Jon carrying the surveying instrument over his

shoulder, and Jak the marker-pole. Arrived at the nearest corner of

their townsite, Jon set the instrument down, while Jak went on to the

next stake.

By means of the graduated circle attached just below the telescope,

and the plumb line suspended from it, Jon adjusted the collapsible

legs until he felt sure it was correctly focussed. Then, as Jak went

ahead from stake to stake, Jon took sights to make sure each marker

was centered on his cross hairs. The ones that were not, he indicated

by hand signals, and Jak reset them to left or right, until Jon was

satisfied.

They completed all of one side before lunch, then returned to the ship.

They found their mother had opened both lockdoors while they were gone,

and fresh, crisp, though warm, air was circulating through the ship,

blowing out the old chemically pure yet "stale-feeling" air their

purifiers had been re-circulating for so long.

Their father was awake, but still so weak he was making no attempt

to sit fully up in bed, although his wife had slipped an extra pillow

beneath his head.

"Ho, fellows!" he greeted the boys as they came into the bunkroom.

"How's the job coming?"

"Just fine, Pop."

"We have the townsite all laid out, and now we're checking to make sure

the lines are straight," Jak told him.

He frowned a bit. "How did you manage it? Neither of you is a surveyor.

Or have you learned how to do that, too?"

"I think I've figured out the theodolite well enough to tell if our

lines are straight, and that's what we're using now," Jon continued. "I

can't measure distances with it, though."

Jak explained more in detail how they had measured the blocks and

street widths, and rechecked them all.

"I can't see why it won't pass," their father said when they finished.

"Probably no one will ever check it, unless they actually use the site

when the colonists come. It shows we were landed here long enough to do

the work, and that's the important thing. What about the rest of the

mapping?"

"I'll go get the papers." Jon ran out, to return in a few minutes with

the book of reports, and the rolls of film and prints they had made on

all the planets and satellites. "You can check these as you feel up to

it, Pop, and anything that looks wrong we can go back and re-check or

do over."

Mr. Carver riffled quickly through the pages, and saw that each

question had been answered; each measurement given an answer--though

whether correct or not, of course, he could not know. All the

information required had been supplied, at least.

He gave the boys his old-time grin, even as he was shaking his head in

wonder. "You chaps certainly have done a job. Looks like I'll have to

take the backseat from now...."

"_No!_" The two boys were shocked by that.

"Not on your life, Pop! We maybe did fairly well, but we need you, just

the same."

"I'll say we do," Jak chimed in. "There's so much yet you can teach us.

Why, we've only begun learning most of the things we want to know."

Mr. Carver smiled up at his sons. "I'm always glad to tell you anything

I can, Fellows. It's good to see you growing up, though." He turned his

head to face Jon more directly. "What's that about a new system you

rigged up so you can land and take off with only one switch?"

Jon explained, and the two were soon deep in technical talk of

electronic relays and cells, and automatic switch-overs. Finally, Mrs.

Carver came in with a tray of lunch for her husband, and told the boys

their food was on the table.

"All right, you chaps, go and eat," Mr. Carver said. "I'll take another

nap while you're out this afternoon. Then maybe I'll feel up to talking

some more this evening, and going over these reports with you."

* * * * *

The second day later the boys finished their re-checking, and came

back to the ship in midafternoon. Their father was again awake, and

they went in to see him.

"We're all done here, Pop, so what say we go back to that fuel-metal

cache and see about getting the stuff aboard?" Jon asked.

"I guess from all you've said that's the most important thing now,"

he agreed after a moment's consideration. "Only thing is, I've been

wondering if you couldn't move me into the control room, and fix a

couch for me there?"

"Sure, that's easy," Jak told him.

But Jon frowned in thought. "Yes, we can do it, but we'll have to

figure out first how to fasten the cot down and then make some

arrangement so you can stand any acceleration we may have to use."

"How about fixing the co-pilot's seat into a bunk?"

"Hey, that's the ticket!" Jon brightened. He ran out and soon was

helping his mother gather blankets, sheets and pillows, and going with

Jak to bring an extra mattress from the storeroom.

They set the seat to recline, and then while Mrs. Carver was making up

the bed, the boys carried their father--a much lighter load now than

when he had first been hurt--and put him in his new bed.

"Say, this is all right!" Mr. Carver exclaimed after Jon had lowered

the co-pilot's visiplate so his father could look into it without

distortion or neck-craning. "All the comforts of home." He grinned at

his wife.

She stooped and kissed him. "Be sure and let us know any time you get

too tired, though, Mr. C."

"I will, Honey," he assured her. "But actually, I'm so comfortable

I don't see why I can't stay here as well as in bed, until the leg's

strong enough to start getting up."

Everything else ready, he watched anxiously, then admiringly, as Jon

started the tubes firing, balanced them and took them off with the

throwing of his one switch. In his visiplate the elder man watched with

intense interest the scenery over which they were passing--Jon had set

course so they would go completely around this world of Two until they

came to that desert. Mr. Carver made many enthusiastic comments about

this splendid planet that now bore his wife's name.

"Yes, and Three's just as nice, only colder," Jon reported eagerly.

"Folks who like cold weather can live there without too much trouble at

all."

"It's funny, though," Jak declared with a frown, "that there's no

protoplasmic life there at all. That we could find," he hastened to add.

"Lots of vegetation, though," Jon added. "That means the soil will be

good for growing things, doesn't it?"

"It certainly sounds like it." His father smiled. "The colonists may

have to adapt their Earth-seeds to fit, and probably bring their own

worms and bees and so on. But they should be able to farm there. From

your surveys, it appears there are plenty of minerals so they can start

mines and factories of all kinds right away. Yes, this looks like a

pretty good solar system."

"You bet, Pop. You sure picked a winner in this one," Jon's eyes

gleamed with satisfaction.

"I had an idea, from the spectroscopic examinations we made 'way back

there near Sirius, that we'd find it fairly good here. But, to be

honest, I didn't dare hope it would be this good. To tell the truth, I

was really more interested in that line which seemed to indicate that

fuel-stuff, than I was in new planets for colonization, although we

needed those, too, to make the trip pay off."

Before long they came above the beginning of that well-remembered

desert, and Jon slowed and circled, preparatory to landing.

Jon kept his eyes upon his instruments, and when he saw they were close

to the actual latitude and longitude, he killed the speed to their

slowest cruising range, and their height to a few hundred yards. When

he knew he was almost at the exact spot, he stared intently into his

pilot's magnifying visiplate, at the same time keeping his fingers

tautly on the landing switch.

Soon, in his plate, he saw the top of that cache cover in the nearing

distance. He circled until he judged he could land close to it, then

closed the switch.

Softly, easily, the space-yacht came in to a landing on the hard packed

sand, and Jon shut off the power and put everything in neutral.

His father had wisely kept silent during this maneuvering, but now he

let out his breath in a _whoosh_.

"That's the neatest landing I ever saw," he told Jon admiringly. "That

gadget of yours will make you a young fortune when we get it back to

Terra."
