In desperation, he twisted. The keazel's head bent. He could hear its breath whistling forth harshly - and again there was that low whine.
Allen writhed above it and clamped knees down upon its cold, scaly abdomen. He twisted the head, further and further. The keazel fought desperately, but Allen's Earthly biceps maintained their hold. He could almost sense the beast's agony in the last stages, when he called up all his strength, - and something snapped.
And the beast lay still.
He rose to his feet, half-sobbing. The Martin night wind knifed into him and the perspiration froze on his body. He was alone in the desert.
Reaction set in. There was an intense buzzing in his ears. He found it difficult to stand. The wind was biting - but somehow he didn't feel it any more.
The buzzing in his ears resolved itself into a voice - a voice calling weirdly through the Martian wind.
'All'n, where are y'? Domn y', y' tanderfoot, where are y'? All'n! All'n!'
New life swept into the Earthman. He tossed the keazel's carcass onto his shoulders and staggered on towards the voice.
'Here I am, G-Gannie. Right here.'
He stumbled blindly into his brother's arms.
George began harshly, 'Y' blasted Airthman, can't y' even keep y'r footing on a sandtruck moving at ten miles per? Y' might've -'
His voice died away in a semi-gurgle.
Allen said tiredly, 'There was a keazel on the roof. He knocked me off. Here, put it somewhere. There's a hundred dollar bonus for every keazel skin brought in to Aresopolis.'
He had no clear recollection of anything for the next half hour. When things straightened out, he was in the truck again with the taste of warm coffee in his mouth. The engine was rumbling once more and the pleasant warmth of the heaters surrounded him.
George sat next to him silently, eyes fixed on the desert ahead. But once in a while, he cleared his throat and shot a lightning glance at his brother. There was a queer look in his eyes.
Allen said, 'Listen, I've got to keep awake - and you look half dead yourself - so how about teaching me that "Gannie quaver" of yours. That's bound to wake the dead.'
The Ganymedan stared even harder and then said gruffly, 'Sure, watch m' Adam's apple while I do 't again.'
The sun was half-way to zenith when they reached the canal.
An hour before dawn there had come the crackling sound of hoarfrost beneath the heavy wheels and that signified the end of the desert area and the approach of the canal oasis. With the rising of the sun, the crackling disappeared and the softening mud underneath slowed the sand-adapted truck. The pathetic clumps of gray-green scrub that dotted the flat landscape were the first variant to eternal red sand since the two had started on their journey.
And then Allen had learned forward and grasped his brother by the arm, 'Look, there's the canal itself right ahead.'
The 'canal' - a small tributary of the mighty Jefferson Canal - contained a mere trickle of water at this season of the year. A dirty winding line of dampness, it was, and little more. Surrounding it on both sides were the boggy areas of black mud that were to fill up into a rushing ice-cold current an Earth-year hence.
The sand-truck nosed gingerly down the gentle slope, weaving a tortuous path among the sparsely-strewn boulders brought down by the spring's torrents and left there as the sinking waters receded.
It slopped through the mud and splashed clumsily through the puddles. It jounced noisily over rocks, muddied itself past the hubs as it made its way through the murky mid-stream channel and then settled itself for the upward pull out.
And then, with a suddenness that tossed the two drivers out of their seats, it sideslipped, made one futile effort to proceed onwards and thereafter refused to budge.
The brothers scrambled out and surveyed the situation. George swore lustily, voice more thickly accented than ever.
'B' Jupe 'n' domn, we're in a pickled situation f'r fair. 'Tis wallowing in the mud there like a blasted pig.'
Allen shoved his hair back wearily, 'Well, don't stand there looking at it. We're still a hundred miles or better from Areso-polis. We've got to get it out of there.'
'Sure, but how?' His imprecations dropped to sibilant breathings as he reached into the truck for the coil of rope in the back. He looked at it doubtfully.
'Y' get in here, All'n, and when I pull, press down with y'r foot on that pedal.'
He was tying the rope to the front axle even as he spoke. He played it out behind him as he slogged out through ankledeep mud, and stretched it taut.
'All right, now, give I' he yelled. His face turned purple with effort as his back muscles ridged. Allen, within the car, pressed the indicated pedal to the floor, heard a loud roar from the engine and a spinning whir from the back wheels. The truck heaved once, and then sank back.
''Tis no use,' George called. 'I can't get a footing. If the ground were dry, I c'd do it.'
'If the ground were dry, we wouldn't be stuck,' retorted Allen. 'Here, give me that rope.'
'D y' think y' can do it, if / can't?' came the enraged cry, but the other had already left the car.
Allen had spied the large, deep-bedded boulder from the truck, and it was with relief that he found it to be within reaching distance of the rope. He pulled it taut and tossed its free end about the boulder. Knotting it clumsily, he pulled, and it held.
His brother leaned out of the car window, as he made his way, back, with one lumped Ganymedan fist agitating the air.
'Hi, y' nitwit. What're y' doing? D' y' expect that overgrown rock t' pull us out?'
'Shut up,' yelled back Allen, 'and feed her the gas when I pull.'
He paused midway between boulder and truck and seized the rope.
'Give!' he shouted in his turn, and with a sudden jerk pulled the rope toward him with both hands.
The truck moved; its wheels caught hold. For a moment it hesitated with the engine blasting ahead full speed, and George's hands trembling upon the wheel. And then it went over. And almost simultaneously, the boulder at the other end of the taut rope lifted out of the mud with a liquid smacking sound and went over on its side.
Allen slipped the noose off it and ran for the truck.
'Keep her going,' he shouted, and hopped onto the running board, rope trailing.
'How did y' do that?' asked George, eyes round with awe.
'I haven't got the energy to explain it now. When we get to Aresopolis and after we've had a good sleep, I'll draw the triangle of forces for you, and show you what happened. No muscles were involved. Don't look at me as if I were Hercules.'
George withdrew his gaze with an effort, 'Triangle o' forces, is it? I never heard o' it, but if that's what it c'n do, education's a great thing.'
'Comet-gas! Is any coffee left?' He stared at the last thermos-bottle, shook it near his ear dolefully, and said, 'Oh, well, let's practice the quaver. It's almost as good and I've practically got it perfected.'
He yawned prodigiously, 'Will we make it by nightfall?'
'Maybe!'
The canal was behind them now.
The reddening sun was lowering itself slowly behind the Southern Range. The, Southern Range is one of the two 'mountain chains' left on Mars. It is a region of hills; ancient, time-worn, eroded hills behind which lies Aresopolis.
It possesses the only scenery worth mentioning on all Mars and also the golden attribute of being able, through the up-drafts along its sides to suck an occasional rain out of the desiccated Martian atmosphere.
Ordinarily, perhaps, a pair from Earth and Ganymede might have idled through this picturesque area, but this was definitely not the case with the Carter twins.
Eyes, puffed for lack of sleep, glistened once more at the sight of hills on the horizon. Bodies, almost broken for sheer weariness, tensed once more when they rose against the sky.
And the truck leaped ahead, - for just behind the hills lay Aresopolis. The road they traveled was no longer a rule-edge straight one, guided by the compass, over table-top-flat land. It followed narrow, twisting trails over rocky ground.
