The Holes Around Mars Part 3

Ja.n.u.s walked a few steps, frowning. Then he said, "I remember reading that there _is_ something darned near a perfect circle in nature." He paused a moment. "Potholes." And he looked at me, as mineralogist, to corroborate.

"What kind of potholes?" I asked cautiously. "Do you mean where part of a limestone deposit has dissol--"

"No. I once read that when a glacier pa.s.ses over a hard rock that's lying on some softer rock, it grinds the hard rock down into the softer, and both of them sort of wear down to fit together, and it all ends up with a round hole in the soft rock."

"Probably neither stone," I told Ja.n.u.s, "would be h.o.m.ogenous. The softer parts would abrade faster in the soft stone. The end result wouldn't be a perfect circle."

Ja.n.u.s's face fell.

"Now," I said, "would anyone care to define this term 'perfect circle'

we're throwing around so blithely? Because such holes as Ja.n.u.s describes are often pretty d.a.m.ned round."

Randolph said, "Well...."

"It is settled, then," Gonzales said, a little sarcastically. "Your discussion, gentlemen, has established that the long, horizontal holes we have found were caused by glacial action."

"Oh, no," Ja.n.u.s argued seriously. "I once read that Mars never had any glaciers."

All of us shuddered.

Half an hour later, we spotted more holes, about a mile down the 'ca.n.a.l,' still on a line, marching along the desert, through cacti, rocks, hills, even through one edge of the low vegetation of the 'ca.n.a.l'

for thirty feet or so. It was the d.a.m.nedest thing to bend down and look straight through all that curling, twisting growth ... a round tunnel from either end.

We followed the holes for about a mile, to the rim of an enormous saucerlike valley that sank gradually before us until, miles away, it was thousands of feet deep. We stared out across it, wondering about the other side.

Allenby said determinedly, "We'll burrow to the _bottom_ of these holes, once and for all. Back to the ship, men!"

We hiked back, climbed in and took off.

At an alt.i.tude of fifty feet, Burton lined the nose of the ship on the most recent line of holes and we flew out over the valley.

On the other side was a range of hefty hills. The holes went through them. Straight through. We would approach one hill--Burton would manipulate the front viewscreen until we spotted the hole--we would pa.s.s over the hill and spot the other end of the hole in the rear screen.

One hole was two hundred and eighty miles long.

Four hours later, we were halfway around Mars.

Randolph was sitting by a side port, chin on one hand, his eyes unbelieving. "All around the planet," he kept repeating. "All around the planet...."

"Halfway at least," Allenby mused. "And we can a.s.sume that it continues in a straight line, through anything and everything that gets in its way...." He gazed out the front port at the uneven blue-green haze of a 'ca.n.a.l' off to our left. "For the love of Heaven, why?"

Then Allenby fell down. We all did.

Burton had suddenly slapped at the control board, and the ship braked and sank like a plugged duck. At the last second, Burton propped up the nose with a short burst, the ten-foot wheels. .h.i.t desert sand and in five hundred yards we had jounced to a stop.

Allenby got up from the floor. "Why did you do that?" he asked Burton politely, nursing a bruised elbow.

Burton's nose was almost touching the front port. "Look!" he said, and pointed.

About two miles away, the Martian village looked like a handful of yellow marbles flung on the desert.

We checked our guns. We put on our oxygen-masks. We checked our guns again. We got out of the ship and made d.a.m.ned sure the airlock was locked.

An hour later, we crawled inch by painstaking inch up a high sand dune and poked our heads over the top.

The Martians were runts--the tallest of them less than five feet tall--and skinny as a pencil. Dried-up and brown, they wore loincloths of woven fiber.

They stood among the dusty-looking inverted-bowl buildings of their village, and every one of them was looking straight up at us with unblinking brown eyes.

The six safeties of our six guns clicked off like a rattle of dice. The Martians stood there and gawped.

"Probably a highly developed sense of hearing in this thin atmosphere,"

Allenby murmured. "Heard us coming."

"They thought that landing of Burton's was an earthquake," Randolph grumbled sourly.

"Marsquake," corrected Ja.n.u.s. One look at the village's scrawny occupants seemed to have convinced him that his life was in no danger.

Holding the Martians covered, we examined the village from atop the thirty-foot dune.

The domelike buildings were constructed of something that looked like adobe. No windows--probably built with sandstorms in mind. The doors were about halfway up the sloping sides, and from each door a stone ramp wound down around the house to the ground--again with sandstorms in mind, no doubt, so drifting dunes wouldn't block the entrances.

The center of the village was a wide street, a long sandy area some thirty feet wide. On either side of it, the houses were scattered at random, as if each Martian had simply hunted for a comfortable place to sit and then built a house around it.

"Look," whispered Randolph.

One Martian had stepped from a group situated on the far side of the street from us. He started to cross the street, his round brown eyes on us, his small bare feet plodding sand, and we saw that in addition to a loincloth he wore jewelry--a hammered metal ring, a bracelet on one skinny ankle. The Sun caught a copperish gleam on his bald narrow head, and we saw a band of metal there, just above where his eyebrows should have been.

"The super-chief," Allenby murmured. "Oh, _shaman_ me!"

As the bejeweled Martian approached the center of the street, he glanced briefly at the ground at his feet. Then he raised his head, stepped with dignity across the exact center of the street and came on toward us, pa.s.sing the dusty-looking buildings of his realm and the dusty-looking groups of his subjects.

He reached the slope of the dune we lay on, paused--and raised small hands over his head, palms toward us.

"I think," Allenby said, "that an anthropologist would give odds on that gesture meaning peace."

He stood up, holstered his gun--without b.u.t.toning the flap--and raised his own hands over his head. We all did.

The Martian language consisted of squeaks.

We made friendly noises, the chief squeaked and pretty soon we were the center of a group of wide-eyed Martians, none of whom made a sound.

Evidently no one dared peep while the chief spoke--very likely the most articulate Martians simply squeaked themselves into the job. Allenby, of course, said they just _squeaked by_.
