The doctor nodded gravely. "There may be some there now!"
II
A DEAD CITY
From a height of a few thousand miles Mercury, at first glance, strongly reminded them of the moon. The general effect was the same--leaden disk, with slight prominences here and there on the circumference, and large, irregular splotches of a darkish shade relieved by a great many brilliantly lighted areas, lines, and spots.
A second glance, however, found a marked difference. Instead of the craters, which always distinguished the moon, Mercury showed ranges of bona fide mountains.
The doctor gave a sigh of regret, mixed with a generous amount of excitement. "Too bad those mountains weren't distinguishable from the earth," he complained. "We wouldn't have been so quick to brand Mercury a dead world."
The others were too engrossed to comment. The sky-car was rapidly sinking nearer and nearer the planet; already Smith had stopped the current with which he had attracted the cube toward the little world's northern hemisphere, and was now using negative voltage. This, in order to act as a brake, and prevent them from falling to destruction.
Suddenly Van Emmon, the geologist, whose eyes had been glued to his binoculars, gave an exclamation of wonder. "Look at those faults!" He pointed toward a region south of that for which they were bound; what might be called the planet's torrid zone.
At first it was hard to see; then, little by little, there unfolded before their eyes a giant, spiderlike system of chasms in the strange surface beneath them. From a point almost directly opposite the sun, these cracks radiated in a half-dozen different directions; vast, irregular clefts, they ran through mountain and plain alike. In places they must have been hundreds of miles wide, while there was no guessing as to their depth. For all that the four in the cube could see, they were bottomless.
"Small likelihood of anybody being alive there now," commented the geologist skeptically. "If the sun has dried it out enough to produce faults like that, how could animal life exist?"
"Notice, however," prompted the doctor, "that the cracks do not extend all the way to the edge of the disk." This was true; all the great chasms ended far short of the "twilight band" which the doctor had declared might still contain life.
But as the sky-car rushed downward their attention became fixed upon the surface directly beneath them, a point whose latitude corresponded roughly with that of New York on the Earth. It was a region of low-lying mountains, decidedly different from various precipitous ranges to be seen to the north and east. On the west, or left-hand side of this district, a comparatively level stretch, with an occasional peak or two projecting, suggested the ancient bed of an ocean.
By this time they were within a thousand miles. Smith threw on a little more current; their speed diminished to a safer point, and they scanned the approaching surface with the greatest of care. The architect, who was a New Yorker, was strongly reminded of the fall aspect of the Appalachians; but Van Emmon, who was born and raised on the Pacific coast, declared that the spot was almost exactly like the region north of San Francisco. "If I didn't know where I was," he declared, "I'd be trying to locate Eureka right now."
The engineer smiled tolerantly. He had spent several years in Scotland, and he felt sure, he obligingly told the others, that this new locality was far more like the Ben Lomond country than any other spot on earth. He was so positive, he made the doctor, a New Zealander, smile quite broadly.
"It is just like the hills near my home," he stated, with an air of finality which made further discussion useless.
"There's a river!" the architect suddenly exclaimed, pointing; then added, before the others could comment, "I mean, what was once a river." They saw that he was right; an irregular but well-defined streak of sandy hue trickled down the middle of their chosen destination--a long, L-shaped valley, surrounded by low hills.
"That's the most likely place, outside of the twilight zone, for life to be found," remarked the doctor. "Neither mountainous nor dead level."
He added: "The spectroscope has plainly shown that there's water vapor in what little air there is. Must be precious little. If the air was as humid as the earth's, we couldn't see the surface at all from this height."
The inviting-looking valley was now less than a hundred miles below. Inviting, however, only in outline; in color it was a grayish buff, scorched and forbidding. The hills were yellower, and an alkali white on their summits.
"Do either of you fellows see anything GREEN?" demanded the engineer, a little later. They were silent; each had noticed long before, that not even near the poles was there the slightest sign of vegetation.
"No chance unless there's foliage," muttered the doctor, half to himself. The builder asked what he meant. He explained: "So far as we know, all animal life depends upon vegetation for its oxygen. Not only the oxygen in the air, but that stored in the plants which animals eat. Unless there's greenery--"
He paused at a low exclamation from Smith. The engineer's eyes were fixed, in wonder and excitement, upon that part of the valley which lay at the joint of the "L" below them. It was perhaps six miles across; and all over the comparatively smooth surface jutted dark projections. Viewed through the glasses, they had a regular, uniform appearance.
"By Jove!" ejaculated the doctor, almost in awe. He leaned forward and scrubbed the dead-light for the tenth time. All four men strained their eyes to see.
It was the architect who broke the silence which followed. The other three were content to let the thrill of the thing have its way with them. Such a feeling had little weight with the expert in archeology.
"Well," he declared jubilantly in his boyish voice, "either I eat my hat or that's a genuine, bona fide city!"
As swiftly as an elevator drops, and as safely, the cube shot straight downward. Every second the landscape narrowed and shrunk, leaving the remaining details larger, clearer, sharper. Bit by bit the amazing thing below them resolved itself into a real metropolis.
Within five minutes they were less than a mile above it. Smith threw on more current, so that the descent stopped; and the cube hung motionless in space.
For another five minutes the four men studied the scene in nervous silence. Each knew that the others were looking for the same thing--some sign of life. A little spot of green, or possibly something in motion--a single whiff of smoke would have been enough to cause a whoop of joy.
But nobody shouted. There was nothing to shout about. Nowhere in all that locality apparently was there the slightest indication that any save themselves were alive.
Instead, the most extraordinary city that man had ever laid eyes upon was stretched directly beneath. It was grouped about what seemed to be the meeting-point of three great roads, which led to this spot from as many passes through the surrounding hills. And the city seemed thus naturally divided into three segments, of equal size and shape, and each with its own street system.
For they undoubtedly were streets. No metropolis on earth ever had its blocks laid out with such unvarying exactness. This Mercurian city contained none but perfect equilateral triangles, and the streets themselves were of absolutely uniform width.
The buildings, however, showed no such uniformity. On the outskirts of this brilliantly tan mystery the blocks seemed to contain nothing save odd heaps of dingy, sun-baked mud. On the extreme north, however, lay five blocks grouped together, whose buildings, like those in the middle of the city, were rather tall, square-cut and of the same dusty, cream- white hue.
"Down-town" were several structures especially prominent for their height. They towered to such an extent, in fact, that their upper windows were easily made out. Apparently they were hundreds of stories high!
Here and there on the streets could be seen small spots, colored a darker buff than the rest of that dazzling landscape. But not one of the spots was moving.
"We'll go down further," said the engineer tentatively, in a low tone. There was no comment. He gradually reduced the repelling current, so that the
sky-car resumed its descent.
They sank down until they were on a level with the top of one of those extraordinary sky-scrapers. The roof seemed perfectly flat, except for a large, round, black opening in its center. No one was in sight.
When opposite the upper row of windows, at a distance of perhaps twenty feet, Smith brought the car to a halt, and they peered in. There were no panes; the windows opened directly into a vast room; but nothing was clearly visible in the blackness save the outlines of the opening in the opposite walls.
They went down further, keeping well to the middle of the space above the street. At every other yard they kept a sharp lookout for the inhabitants; but so far as they could see, their approach was entirely unobserved.
When within fifty yards of the surface, all four men made a search for cross-wires below. They saw none; there were no poles, even. Neither, to their astonishment, was there such a thing as a sidewalk. The street stretched, unbroken by curbing, from wall to wall and from corner to corner.
As the cube settled slowly to the ground, the adventurers left the deadlight to use the windows. For a moment the view was obscured by a swirl of dust, raised by the spurt of the current; then this cloud vanished, settling to the ground with astounding suddenness, as though jerked down by some invisible hand.
Directly ahead of them, distant perhaps a hundred yards, lay a yellowish-brown mass of unusual octagonal shape. One end contained a small oval opening, but the men from the Earth looked in vain for any creature to emerge from it.
The doctor silently set to work with his apparatus. From an air-tight double-doored compartment he obtained a sample of the ether outside the car; and with the aid of previously arranged chemicals, quickly learned the truth.
There was no air. Not only was there no oxygen, the element upon which all known life depends, but there was no nitrogen, no carbon dioxide; not the slightest trace of water vapor or of the other less known elements which can be found in small amounts in our own atmosphere. Clearly, as the doctor said, whatever air the astronomers had observed must exist on the circumference of the planet only, and not in this sun- blasted, north-central spot.
On the outer walls of the cube, so arranged as to be visible through the windows, were various instruments. The barometer showed no pressure. The thermometer, a specially devised one which used gas instead of mercury, showed a temperature of six hundred degrees, Fahrenheit.
No air, no water, and a baking heat; as the geologist remarked, how could life exist there? But the architect suggested that possibly there was some form of life, of which men knew nothing, which could exist under such circumstances.
They got out three of the suits. These were a good deal like those worn by divers, except that the outer layer was made of non-conducting aluminum cloth, flexible, air-tight, and strong. Between it and the inner lining was a layer of cells, into which the men now pumped several pints of liquid oxygen. The terrific cold of this chemical made the heavy flannel of the inner lining very welcome; while the oxygen itself, as fast as it evaporated, revitalized the air within the big, glass- faced helmet.
Once safely locked within the clumsy suits, Jackson, Van Emmon, and Smith took their places within the vestibule; while the doctor, who had volunteered to stay behind, watched them open the outer door. With a hiss all the air in the vestibule rushed out; and the doctor earnestly thanked his stars that the inner door had been built very strongly.
The men stepped out on to the ground. At first they moved with great care, being uncertain that their feet were weighted heavily enough to counteract the reduced gravitation of the tiny planet. But they had been living in a very peculiar condition, gravitationally speaking, for the past three days; and they quickly adapted themselves. After a little shifting about, the three artificial monsters gave their telephone wires another scrutiny; then, keeping always within ten feet of each other, so as not to throw any strain on the connections, they strode in a matter- of-fact way toward the nearest doorway.
For a moment or two they stood outside the queer, peaked archway, their glimmering suits standing out oddly in the blinding sunlight. Then they advanced boldly into the opening; in a flash they vanished from the doctor's sight, and the inklike blackness of the opening again stared at him from that dazzling wall.
III
THE HOUSE OF DUST
The geologist, strong man that he was, and by profession an investigator of the unknown--Van Emmon--took the lead. He stalked straight ahead into a vast space which, without any preliminary hallway, filled the entire triangular block.
Before their eyes were accustomed to the shadow--"Pretty cold," murmured the architect into the phone transmitter; it was fastened to the inside of the helmet, directly in front of his mouth, while the receiver was placed beside his ear. All three stopped short to adjust each other's electrical heating apparatus. To do this, they did not use their fingers directly; they manipulated ingenious non-magnetic pliers attached to the ends of fingerless, insulated mittens.
Before they had finished, the builder, who had been puzzling over the extraordinary suddenness with which that cloud of dust had settled, received an inspiration. He was carrying note-book and camera. With his pliers he tore out a sheet from the former, and holding book in one hand and the leaf in the other, he allowed them to drop at the same instant.
They reached the ground together.
"See?" The architect repeated the experiment. "Back home, where there's air, the paper would have floated down; it would have taken three times as long for it to fall as the book."
Smith nodded, but he had been thinking of something else. He said gravely: "Remember what I told you--it's air that insulates the earth from the ether. If there's no air here--" he glanced out into the pitiless sunlight--"then I hope there's no flaw in our insulation. We're walking in an electrical bath."
They looked around. Objects were pretty distinct now. They could easily see that the floor was covered with what appeared to be machines, laid out in orderly fashion. Here, however, as outside, everything was coated with that fine, cream-colored dust. It filled every nook and cranny; it stirred about their feet with every step.
The geologist led the way down a broad aisle, on either side of which towered immense machinery. Smith was for stopping to examine them one by one; but the others vetoed the engineer's passion, and strode on toward the end of the triangle. More than anything else, they looked for the absent population to show itself.
Suddenly Van Emmon stopped short. "Is it possible that they're all asleep?" He added that, even though the sun shone steadily the year around, the people must take time for rest.
But Smith stirred the dust with his foot and shook his head. "I've seen no tracks. This dust has been lying here for weeks, perhaps months. If the folks are away, then they must be taking a community vacation."
At the end of the aisle they reached a small, railed-in space, strongly resembling what might be seen in any office on the earth. In the middle of it stood a low, flat-topped desk, for all the world like that of a prosperous real-estate agent, except that it was about half a foot lower. There was no chair. For lack of a visible gate in the railing, the explorers stepped over, being careful not to touch it.
There was nothing on top of the desk save the usual coat of dust. Below, a very wide space had been left for the legs of whoever had used it; and flanking this space were two pedestals, containing what looked to be a multitude of exceedingly small drawers. Smith bent and examined them; apparently they had no locks; and he unhesitatingly reached out, gripped the knob of one and pulled.
Noiselessly, instantaneously, the whole desk crumbled to powder. Startled, Smith stumbled backwards, knocking against the railing. Next instant it lay on the floor, its fragments scarcely distinguishable from what had already covered the surface. Only a tiny cloud of dust arose, and in half a second this had settled.
The three looked at each other significantly. Clearly, the thing that had just happened argued a great lapse of time since
the user of that desk officiated in that enclosure. It looked as though Smith's guess of "weeks, perhaps months," would have to be changed to years, perhaps centuries.
"Feel all right?" asked the geologist. Jackson and Smith made affirmative noises; and again they stepped out, this time walking in the aisle along the outer wall. They could see their sky-car plainly through the ovals.
Here the machinery could be examined more closely. They resembled automatic testing scales, said Smith; such as is used in weighing complicated metal products after finishing and assembling. Moreover, they seemed to be connected, the one to the other, with a series of endless belts, which Smith thought indicated automatic production. To all appearances, the dust-covered apparatus stood just as it had been left when operations ceased, an unguessable length of time before.
Smith showed no desire to touch the things now. Seeing this, the geologist deliberately reached out and scraped the dust from the nearest machine; and to the vast relief of all three, no damage was done. The dust fell straight to the floor, exposing a brilliantly polished streak of greenish-white metal.
Van Emmon made another tentative brush or so at other points, with the same result. Clean, untarnished metal lay beneath all that dust. Clearly it was some non-conducting alloy; whatever it was, it had successfully resisted the action of the elements all the while that such presumably wooden articles as the desk and railing had been steadily rotting.
Emboldened, Smith clambered up on the frame of one of the machines. He examined it closely as to its cams, clutches, gearing, and other details significant enough to his mechanical training. He noted their adjustments, scrutinized the conveying apparatus, and came back carrying a cylindrical object which he had removed from an automatic chuck.
"This is what they were making," he remarked, trying to conceal his excitement. The others brushed the dust from the thing, a huge piece of metal which would have been too much for their strength on the earth. Instantly they identified it.
It was a cannon shell.
