Stand by for Mars! Part 46

"Must be at least three hundred miles."

"Let's start moving," said Roger, "and hope we can find something that'll float us on the ca.n.a.l."

Single file, wearing the s.p.a.ce cloths once more as protection against the sun, they walked along the bank of the ca.n.a.l. When the heat became unbearable, they dipped the squares of s.p.a.ce cloths into the water and wrapped themselves in them. When they began to dry out, they would repeat the process. At noon, when the sun dried the fabric nearly as fast as they could wet it, they stopped and slipped over the edge of the bank into the cool water. Covering their heads with the cloths they remained partly submerged until the late afternoon. When the sun had lost some of its power, again they climbed out and continued walking.

Marching late into the night, they made camp beside the ca.n.a.l, finished the last container of food, and, for the first time since leaving the ship, slept during the night. By the time Deimos had risen in the sky, they were sound asleep.

CHAPTER 22

"Eeeeeeoooooooow!" Astro's bull-like roar shattered the silence of the desert. "There--up ahead, Tom--Roger--a building!"

Tom and Roger stopped and strained their eyes in the bright sunshine.

"I think you're right," said Tom at last. "But I doubt if anyone's there. Looks like an abandoned mining shack to me."

"Who wants to stand here and debate the question?" asked Roger, and started off down the side of the ca.n.a.l at a lope, with Astro and Tom right behind him.

During the last three days the boys had been living off the contents of the last remaining food container and the few lichens they found growing along the ca.n.a.l. Their strength was weakening, but with an abundant supply of water near at hand and able to combat the sun's heat with frequent swims, they were still in fair condition.

Tom was the first to reach the building, a one-story structure made of dried mud from the ca.n.a.l. The shutters and the door had long since been torn away by countless sandstorms.

The three boys entered the one-room building cautiously. The floor was covered with sand, and sand was piled in heaping drifts in front of the open windows and door.

"Nothing--not a thing," said Roger disgustedly. "This place must be at least a hundred and fifty years old."

"Probably built by a miner," commented Tom.

"What do you mean 'nothing'?" said Astro. "Look!"

They followed Astro's pointing finger to the ceiling. Crisscrossed, from wall to wall, were heavy wooden beams.

"Raft!" Tom cried.

"That's right, s.p.a.ceman," said Astro, "a raft. There's enough wood up there to float the _Polaris_. Come on!"

Astro hurried outside, with Tom and Roger following at his heels. They quickly climbed to the roof of the old building and soon were ripping the beams from the crumbling mud. Fortunately the beams had been joined by notching the ends of the crosspieces. Astro explained that this was necessary because of the premium on nails when the house was built.

Everything at that time had to be hauled from Earth, and no one wanted to pay the price heavy nails and bolts demanded.

One by one, they removed the heavy beams, until they had eight of them lined up alongside the edge of the ca.n.a.l.

"How do we keep them together?" asked Roger.

"With this!" said Tom. He began ripping his s.p.a.ce cloth into long strips. Astro and Roger tugged at the first beam. At last they had it in the water.

"It floats," cried Astro. Tom and Roger couldn't help but shout for joy.

They quickly hauled the remaining beams into the water and lashed them together. Without hesitation, they shoved the raft into the ca.n.a.l, climbing aboard and standing like conquering heroes, as the raft moved out into the main flow of the ca.n.a.l and began to drift forward.

"I dub thee--_Polaris the Second_," said Tom in formal tones and gave the nearest beam a kick.

Astro and Roger gave a l.u.s.ty cheer.

Steadily, silently, the raft bore them through the never-changing scene of the ca.n.a.l's muddy banks and the endlessness of the desert beyond.

Protecting themselves from the sun during the day by repeated dunkings in the water, they traveled day and night in a straight course down the center of the ca.n.a.l. At night, the tiny moon, Deimos, climbed across the desert and reflected light upon the satin-smooth water.

The third day on the raft they began to feel the pangs of hunger. And where during their march through the desert, their thoughts were of water, now visions of endless tables of food occupied their thoughts. At first, they talked of their hunger, dreaming up wild combinations of dishes and giving even wilder estimates of how much each could consume.

Finally, discovering that talking about it only intensified their desire, they kept a stolid silence. When the heat became unbearable, they simply took to the water. Once Tom's grip on the raft slipped and Roger plunged in after him without a moment's hesitation, only to have Astro go in to save both of them.

On and on--down the ca.n.a.l, the three boys floated. Days turned into nights, and nights, cooling and refreshing, gave way to the blazing sun of the next day. The silent desert swept past them.

One night, when Astro, unable to sleep, was staring ahead into the darkness, he heard a rustling in the water alongside the raft. He moved slowly to the edge of the raft and peered down into the clear water.

He saw a fish!

The big cadet watched it dart around the raft. He waited, his body tense. Once the fish came to the edge of the raft, but before Astro could move his arm, it darted off in another direction.

At last the fish disappeared and Astro sank back on the timbers. He trailed one hand over the side in the water, and suddenly, felt the rough scales of the fish brush his fingers. In a flash, Astro closed his hand and s.n.a.t.c.hed the wriggling creature out of the water.

"Tom--Roger--" he shouted. "Look--look--a fish--I caught a fish with my bare hands!"

Tom rolled over and opened his eyes. Roger sat in bewilderment.

"I watched him--I was watching him and then he went away. And then I held my hand over the side of the raft and he came snooping around and--well, I just grabbed him!"

He held the fish in the viselike grip of his right hand until it stopped moving.

"You know," said Tom weakly, "I just remembered. When we were in the Science Building in Atom City, one of their projects was to breed both Earth and Venus fish in the ca.n.a.ls."

"I am going to shake, personally, the hand of the man who started this project when we get back to Atom City," said Astro.

Suddenly Roger gripped Tom's arms. He was staring in the direction the raft was going. "Tom--" he breathed, "Astro--look!"

They turned and peered into the dusk. In the distance, not a mile away, was the huge crystal-clear dome of the atmosphere booster station, its roaring atomic motors sending a steady purring sound out across the desert.

"We made it," said Tom, choking back the tears. "We made it!"

"Well, blast my jets," said Astro. "We sure did!"

"And you mean to tell me, you _walked_ across that desert?" asked Captain Strong.

Tom glanced over at Astro and Roger. "We sure did, sir."
