"You remember, of course, what sort of a man I got in touch with. Powart was easily the greatest Capellan of them all; a magnificent intellect, which I still think was intended to have ruled the rest. I haven't backed down from my original position."

"Van! You still believe," incredulously, "in a government of the sort he contemplated?"

Van Emmon nodded aggressively. "All that we learned merely strenthens my conviction. Remember what sort of people the working classes of Capellette were? Smith's 'agent' was typical—a helpless nincompoop, not fit to govern himself!" The geologist strove to keep his patience.

"However," remarked Kinney, "the chap whose mind I used was no fool."

"Nor was Billie's agent, the woman surgeon," agreed Van Emmon, "even if she did prefer 'the Devolutionist' to Powart. But you'll have to admit, doc, that the vast majority of the Capellans were incompetents; the rest were exceptions."

The doctor spoke after a brief pause. "And—that's what is wrong, Van?"

"Yes," grimly. "Billie can't help but rejoice that things turned out the way they did. She is sure that the workers, now that they've been separated from the ruling class, will proceed to make a perfect paradise out of their land." He could not repress a certain amount of sarcasm. "As well expect a bunch of monkeys to build a steam engine!

"Well," after a little hesitation, "as I said before, doc, I've no reason to change my mind. You may talk all you like about it—I can't agree to such ideas. The only way to get results on that planet is for the upper classes to continue to govern."

"And this is what you two have—quarreled about?"

Van Emmon nodded sorrowfully. He lit another cigar absent-mindedly and cleared his throat twice before going on:

"My fault, I guess. I've been so darned positive about everything I've said, I've probably caused Billie to sympathize with her friends more solidly than she would otherwise."

"But just because you've championed the autocrats so heartily—"

"I'm afraid so!" The geologist was plainly relieved to have stated the case in full. He leaned forward in his eagerness to be understood. He told the doctor things that were altogether too personal to be included in this account.

Meanwhile, out in the doctor's study, Smith had made no move whatever to interrogate the geologist's young wife. Instead, the engineer simply remained standing after Billie had sat down, and gave her only an occasional hurried glance. Shortly the silence got on her nerves; and—such was her nature, as contrasted with Van Emmon's—whereas he had stated causes first, she went straight to effects.

"Well," explosively, "Van and I have split!"

Smith was seldom surprised at anything. This time was no exception. He merely murmured "Sorry" under his breath; and Billie rushed on, her pent-up feelings eager to escape.

"We haven't mentioned Capellette for weeks, Smith! We don't dare! If we did, there'd be such a rumpus that we—we'd separate!" Something came up into her throat which had to be choked back before she could go on. Then—

"I don't know why it is, but every time the subject is brought up Van makes me so WILD!" She controlled herself with a tremendous effort. "He blames me, of course, because of what I did to help the Devolutionist. But I can't be blamed for sympathizing with the under dog, can I? I've always preferred justice to policy, any time. Justice first, I say! And I think we've seen—there on Capellette—how utterly impossible it is for any such system as theirs to last indefinitely."

But before she could follow up her point the door opened and the doctor returned with her husband. Kinney did not allow any tension to develop; instead, he said briskly:

"There's only a couple of hours remaining between now and dinner time; I move we get busy." He glanced about the room, to see if all was in place. The four chairs, each with its legs tipped with glass; the four footstools, similarly insulated from the floor; the electrical circuit running from the odd group of machinery in the corner, and connecting four pair of brass bracelets—all were ready for use. He motioned the others to the chairs in which they had already accomplished marvels in the way of mental traveling.

"Now," he remarked, as he began to fit the bracelets to his wrists, an example which the rest straightway followed; "now, we want to make sure that we all have the same purpose in mind. Last time, we were simply looking for four people, such as had view-points similar to our own. To-day, our object is to locate, somewhere among the planets attached to one of the innumerable sun-stars of the universe, one on which the conditions are decidedly different from anything we have known before."

Billie and Van Emmon, their affair temporarily forgotten, listened eagerly.

"As I recall it," Smith calmly observed, "we agreed that this attempt would be to locate a new kind of—well, near-human. Isn't that right?"

The doctor nodded. "Nothing more or less"—speaking very distinctly—"than a creature as superior as we are, but NOT IN HUMAN FORM."

Smith tried hard not to share the thrill. He had been reading biology the previous week. "I may as well protest, first as last, that I don't see how human intelligence can ever be developed outside the human form. Not—possibly!"

Van Emmon also was skeptical, but his wife declared the idea merely unusual, not impossible. "Is there any particular reason against it?" she demanded of the doctor.

"I will say this much," cautiously. "Given certain conditions, and inevitably the human form will most certainly become the supreme creature, superior to all the others.

"However, suppose the planetary conditions are entirely different. I conceive it entirely possible for one of the other animals to forge ahead of the man-ape; quite possible, Smith," as the engineer started to object, "if only the conditions are different ENOUGH.

"At any rate, we shall soon find out. I have been reading further in the library the Venusians gave us, and I assure you that I've found some astonishing things." He fingered one of the diminutive volumes. "There is one planet in particular, whose name I have forgotten, where all animal life has disappeared entirely. There are none but vegetable forms on the land, and all of them are the rankest sort of weeds. They have literally choked off everything else!

"And the highest form of life there is a weed; a hideous monstrosity, shaped something like an octopus, and capable of the most horrible—" He stopped abruptly, remembering that one of his hearers was a woman. "Never mind about that now."

He indicated another of the little books. "I think we will do well to investigate a planet which the Venusians call 'Sanus.' It belongs to the tremendous planetary family of the giant star Arcturus. I haven't read any details at all; I didn't want to know more than you. We can proceed with our discoveries on an equal footing."

"But," objected Smith, recalling the previous methods, "how are we to put our minds in touch with any of theirs, unless we know enough about them to imagine their viewpoints?"

"Our knowledge of their planet's name and location," replied the doctor, "makes it easier for us. All we have to do is to go into the telepathic state, via the Venusian formula; then, at the same time, each must concentrate upon some definite mental quality, some particular characteristic of his own mind, which he or she wishes to find on Sanus. It makes no difference what it may be; all you have to do is, exert your imaginations a little."

There was a pause, broken by Smith: "We ought to tell each other what we have in mind, so that we don't conflict."

"Yes. For my part," said the doctor, "I'd like to get in touch with a being who is mildly rebellious; not a violent radical, but a philosophical revolutionist. I don't care what sort of a creature he, she, or it may be, so long as the mind is in revolt against whatever injustice may exist."

"Then I," stated Smith, "will stick to the idea of service." Nobody was surprised that the engineer should make such a choice; he was, first, last, and all the time, essentially a useful man.

Van Emmon was not ready with his choice. Instead: "You say, doc, that you know nothing further about Sanus than what you've already told us?"

"I was about to mention that. The Venusians say that conditions are reversed from what we found on Capellette. Instead of Sanus being ruled by a small body of autocrats, it is—ruled by the working class!"

"Under the circumstances," said Van, "I'll take something different from what I got last time. No imperiousness this trip." He smiled grimly. "There was a time when I used to take orders. Suppose you call my choice 'subordinacy.'"

"How very noble of you!" gibed Billie. "My idea is supremacy, and plenty of it! I want to get in touch with the man higher up—the worker who is boss of the whole works!" She flashed a single glance at her husband, then threw herself back in her chair. "Go ahead!"

And before two minutes were up, the power of concerted thought, aided by a common objective and the special electrical circuit which joined them, had projected the minds of the four across the infinite depths of space. The vast distance which separated their bodies from Sanus was annihilated, literally as quick as thought.

Neither of the four stirred. To all appearances they were fast asleep. The room was quite still; only the clock ticked dully on the wall. Down-stairs, the doctor's wife kept watch over the house.

The greatest marvel in creation, the human mind, was exploring the unknown.



II

ALMOST HUMAN



Of course, the four still had the ability to communicate with each other while in the trance state; they had developed this power to a fair degree while investigating Capellette. However, each was so deeply interested in what he or she was seeing during the first hour of their Sanusian experiences that neither thought to discuss the matter until afterward.

When the doctor first made connection with the eyes of his agent, he instinctively concluded that he, at least, had got in touch with a being more or less like himself. The whole thing was so natural; he was surveying a sunny, brush-covered landscape from eyes whose height from the ground, and other details, were decidedly those of a human.

For a moment there was comparative silence. Then his unknown agent swiftly raised something—a hand, presumably—to a mouth, and gave out a piercing cry. Whereupon the doctor learned something that jarred him a trifle. His agent was—a woman!

He had time to congratulate himself upon the fact that he was (1) a doctor, (2) a married man, (3) the father of a daughter or two, before his agent repeated her cry. Almost immediately it was answered by another exactly like it, from an unseen point not far away. The Sanusian plainly chuckled to herself with satisfaction.

A moment later there came, rather faintly, two more calls, each from a different direction in the dun-colored brush. Still without moving from the spot, the doctor's agent replied two or three times, meanwhile watching her surroundings very closely. Within half a minute the first of her friends came in sight.

It was a young woman. At a distance of about twenty yards she appeared to be about five feet tall and sturdily built. She was dressed in a single garment, made of the skin of some yellow, short-haired animal. It may have been a lion cub. Around her waist was a strip of hide, which served as a belt, and held a small, stone-headed tomahawk. One shoulder and both legs were left quite bare, revealing a complexion so deeply tanned that the doctor instantly thought: "Spanish!"

In a way, the girl's face gave the same impression. Large, dark-brown eyes, full lips and a healthy glow beneath her tan, all made it possible for her to pass as a Spaniard. However, there was nothing in the least coquettish about her; she had a remarkably independent manner, and a gaze as frank and direct as it was pure and untroubled.

In one hand she carried a branch from some large-leafed shrub. The eyes which Kinney was using became fixed upon this branch; and even as the newcomer cried out in joyous response to the other's greeting, her expression changed and she turned and fled, laughing, as the doctor's agent darted toward her. She did not get away, and immediately the two were struggling over the possession of the branch.

In the midst of the tussle another figure made its appearance.

"Look out! Here comes Dulnop!" [Footnote: It made no difference whatever as to what language was used. The telepathic process employed enabled the investigators to know all that their agents' subconscious minds took in. The brains of the four automatically translated these thought-images into their own language. However, this method did not enable them to learn what their agents were thinking, but only what they said, heard, and saw.] cried Kinney's agent; at the same time she made a special effort, and succeeded in breaking off a good half of the branch.

Instantly she darted to one side, where she calmly began to pluck some small, hard-shelled nuts from the branch, and proceeded to crack them, with entire ease, using a set of teeth which must have been absolutely perfect.

She gave the latest comer only a glance or two. He—for it certainly was a man—was nearly a half a foot taller than the girl already described; but he was plainly not much older or younger, and in build and color much the same. He was clothed neither more nor less than she, the only difference being that some leopardlike animal had contributed the material. In his belt was tucked a primitive stone hammer, also a stone knife. His face was longer than hers, his eyes darker; but he was manifestly still very boyish. Dulnop, they had called him.

"Hail, Cunora!" he called to the girl who had brought the nuts; then, to her who was watching: "Rolla! Where got ye the nuts?"

Rolla didn't answer; she couldn't use her mouth just then; it was too full of nuts. She merely nodded in the direction of Cunora.

"Give me some, Cunora!"

The younger girl gave no reply, but backed away from him as he approached; her eyes sparkled mischievously and, the doctor thought, somewhat affectionately. Dulnop made a sudden darting move toward her branch, and she as swiftly whirled in her tracks, so that he missed. However, he instantly changed his mind and grasped the girl instead. Like a flash he drew her to him and kissed her noisily.

Next second he was staggering backward under the weight of her hard brown fist. "Do that again, and I'll have the hair out of thy head!" the girl screamed, her face flaming. Yet Kinney saw that the man was laughing joyously even as he rubbed the spot where her blow had landed, while the expression of her eyes quite belied what she had said.

Not until then did the doctor's agent say anything. When she spoke it was in a deep, contralto voice which gave the impression of riper years than either of the other two. Afterward Kinney learned that Rolla was nearly ten years their senior, a somewhat more lithe specimen of the same type, clad in the skin of what was once a magnificent goat. She carried only a single small knife in her belt. As seen reflected in pools of water, her complexion was slightly paler and her whole expression a little less self-assertive and distinctively philosophical. To those who admire serious, thoughtful women of regular feature and different manner, Rolla would have seemed downright beautiful.

"Dulnop," said she, with a laugh in her voice, "ye will do well to seek the nut tree, first as last." She nonchalantly crushed another shell in her mouth. "Neither Cunora nor I can spare good food to a kiss-hungry lout like thee!"

He only laughed again and made as though to come toward her. She stood ready to dodge, chuckling excitedly, and he evidently gave it up as a bad job. "Tell me whence cameth the nuts, Cunora!" he begged; but the girl pretended to be cross, and shut her mouth as firmly as its contents would allow.

Next moment there was a shout from the thicket, together with a crashing sound; and shortly the fourth Sanusian appeared. He was by far the larger; but his size was a matter of width rather than of height. An artist would have picked him as a model for Ajax himself. His muscles fairly strained the huge lion's skin in which he was clad, and he had twice the weight of Dulnop within the same height. Also, to the doctor's eye, he was nearer Rolla's age.

His face was strong and handsome in a somewhat fierce, relentless way; his complexion darker than the rest. He carried a huge club, such as must have weighed all of forty pounds, while his belt was jammed full of stone weapons. The doctor classed him and the younger girl together because of their vigor and independence, while Dulnop and Rolla seemed to have dispositions very similar in their comparative gentleness and restraint.

"Hail, all of ye!" shouted this latest arrival in a booming baritone. He strode forward with scarcely a glance at the two younger people; his gaze was fixed upon Rolla, his expression unmistakable. The woman quietly turned upon Dulnop and Cunora.

"Look!" she exclaimed, pointing to a spot back of them. "See the curious bird!" They wheeled instantly, with the unquestioning faith of two children; and before they had brought their gazes back again, the big man had seized Rolla, crushed her to his breast and kissed her passionately. She responded just as warmly, pushing him away only in order to avoid being seen by the others. They showed only an innocent disappointment at having missed seeing the "curious bird."

"A simple-minded people, basically good-humored," was the way the doctor summed the matter up when reporting what he had seen. However, it was not so easy to analyze certain things that were said during the time the four Sanusians spent in each other's company. For one thing—

"Did They give thee permission to go?" Rolla was asked by the big man. His name, it seemed, was Corrus.

"Yes, Corrus. They seemed to think it a good idea for us to take a little recreation to-day. I suppose ye left thy herd with thy brother?"

He nodded; and the doctor was left to wonder whom "They" might be. Were They a small group of humans, whose function was to superintend? Or were They, as the books from Venus seemed to indicate, another type of creature, entirely different from the humans, and yet, because of the peculiar Sanusian conditions, superior to the humans?

"They have decided to move their city a little farther away from the forest," Rolla overheard Dulnop telling Cunora; which was the first indication that the planet boasted such a thing as a city. Otherwise, things appeared to be in a primitive, rather than a civilized condition.

These four skin-clad savages seemed to be enjoying an aboriginal picnic. For lunch, they munched on various fruits and nuts picked up en route, together with handfuls of some wheatlike cereal which the big man had brought in a goatskin. From time to time they scared out various animals from the brush, chasing the creatures after the fashion of dogs and children. Whenever they came to a stream, invariably all four splashed through it, shouting and laughing with delight.

However, there were but two of these streams, and both of them quite small. Their banks indicated that either the season was very far advanced, or else that the streams were at one time vastly larger.

"A rather significant fact," the doctor afterward commented.

Nevertheless, the most impressive thing about all that the doctor learned that day was the strange mariner in which the excursion came to an end. The quartet was at that moment climbing a small hill, apparently on the edge of an extensive range of mountains. An occasional tree, something like an oak, broke the monotony of the brush at this point, and yet it was not until Rolla was quite at the top of the knoll that Kinney could see surrounding country with any degree of clearness. Even then he learned little.

The hill was placed on one edge of a valley about forty miles in width. A good part of it was covered with dusty vegetation, presumably wild; but the rest was plainly under cultivation. There were large green areas, such as argued grain fields; elsewhere were what looked like orchards and vineyards, some of which were in full bloom—refuting the notion that the season was a late one. Nowhere was there a spot of land which might be called barren.

Rolla and her three friends stood taking this in, keeping a rather curious silence meanwhile. At length Cunora gave a deep sigh, which was almost instantly reproduced by all the rest. Corrus followed his own sigh with a frank curse.

"By the great god Mownoth!" he swore fiercely. "It be a shame that we cannot come hence a great deal oftener! Me-thinks They could allow it!"

"They care not for our longings," spoke Cunora, her eyes flashing as angrily as his. "They give us enough freedom to make us work the better—no more! All They care for is thy herd and my crops!"

"And for the labor," reminded the big man, "of such brains as Rolla's and Dulnop's. It be not right that They should drive us so!"

"Aye," agreed the younger man, with much less enthusiasm. "However, what can ye do about it, Corrus?"

The big man's face flushed, and he all but snarled. "I tell ye what I can do I, and ye as well, if ye but will! I can—"

He stopped, one hand upraised in mighty emphasis, and a sudden and startling change came over him. Downright fear drove the anger from his face; his massive body suddenly relaxed, and all his power and vigor seemed to crumble and wilt. His hands shook; his mouth trembled. At the same time the two women shrank from him, each giving an inarticulate cry of alarm and distress. Dulnop gave no sound, but the anger which had left the herdsman seemed to have come to him; the youngster's eyes flared and his breast heaved. His gaze was fixed upon Corrus's neck, where the sweat of fear already glistened.

Suddenly the big man dropped his head, as though in surrender. He gasped and found voice; this time a voice as shaky and docile as it had been strong and dominant a moment before.

"Very well," he spoke abjectly. "Very well. I—shall do as you wish." He seemed to be talking to thin air. "We—will go home at once."

And instantly all four turned about, and in perfect silence took the back trail.



III

WORLD OF MAMMOTHS



Immediately upon going into tele-consciousness Smith became aware of a decided change in his surroundings. The interior of the study had been darkened with drawn shades; now he was using eyes that were exposed to the most intense sunlight. The first sight that he got, in fact, was directed toward the sky; and he noted with an engineer's keen interest that the color of the sky was blue, slightly tinged with orange. This, he knew, meant that the atmosphere of Sanus contained at least one chemical element which is lacking on the earth.

For a minute or two the sky remained entirely clear. There were no clouds whatever; neither did any form of winged life make its appearance. So Smith took note of sounds.

Presumably his agent—whoever or whatever it might be—was located in some sort of aircraft; for an extremely loud and steady buzzing, suggesting a powerful engine, filled the engineer's borrowed ears. Try as he might, however, he could not identify the sound exactly. It was more like an engine than anything else, except that the separate sounds which comprised the buzz occurred infinitely close together. Smith concluded that the machine was some highly developed rotary affair, working at perhaps six or eight thousand revolutions a minute—three or four times as fast as an ordinary engine.

Meanwhile his agent continued to stare into the sky. Shortly something arrived in the field of vision; a blurred speck, far to one side. It approached leisurely, with the unknown agent watching steadfastly. It still remained blurred, however; for a long time the engineer knew as little about its actual form as he knew about his mysterious agent.

Then, like a flash, the vision cleared. All the blurring disappeared instantly, and the form of a buzzard was disclosed. It was almost directly overhead, about a quarter of a mile distant, and soaring in a wide spiral. No sound whatever came from it. Smith's agent made no move of any kind, but continued to watch.

Shortly the buzzard "banked" for a sharper turn; and the engineer saw, by the perspective of its apparent speed, that the aircraft whose use he was enjoying was likewise on the move. Apparently it was flying in a straight line, keeping the sun—an object vastly too brilliant to examine—on the right.

The buzzard went out of sight. Once more the clear sky was all that could be seen; that, and the continual roar of the engine, were all that Smith actually knew. He became impatient for his agent to look elsewhere; it might be that the craft contained other specimens of the unknown creatures. But there was no change in the vigilant watch which was being kept upon the sky.

Suddenly the engineer became exceedingly alert. He had noticed something new—something so highly different from anything he had expected to learn that it was some minutes before he could believe it true.

His borrowed eyes had no eyelids! At least, if they did, they were never used. Not once did they flicker in the slightest; not once did they blink or wink, much less close themselves for a momentary rest from the sun's glare. They remained as stonily staring as the eyes of a marble statue.

Then something startling happened. With the most sickening suddenness the aircraft came to an abrupt halt. Smith's senses swam with the jolt of it. All about him was a confused jumble of blurred figures and forms; it was infinitely worse than his first ride in a hoist. In a moment, however, he was able to examine things fairly well.

The aircraft had come to a stop in the middle of what looked like a cane brake. On all sides rose yellowish-green shafts, bearing leaves characteristic of the maize family. Smith knew little about cane, yet felt sure that these specimens were a trifle large. "Possibly due to difference in gravitation," he thought.

However, he could not tell much about the spot on which the machine had landed. For a moment it was motionless; the engine had been stopped, and all was silent except for the gentle rustling of the cane in the field. The unknown operator did not change his position in the slightest.

Then the craft began to move over the surface, in a jerky, lurching fashion which indicated a very rough piece of ground. At the same time a queer, leathery squeaking came to the engineer's borrowed ears; he concluded that the machine was being sorely strained by the motion. At the time he was puzzled to account for the motion itself. Either there was another occupant of the craft, who had climbed out and was now pushing the thing along the ground, or else some form of silent mechanism was operating the wheels upon which, presumably, the craft was mounted. Shortly the motion stopped altogether.

It was then that Smith noticed something he had so far ignored because he knew his own dinner hour was approaching. His agent was hungry, like himself. He noticed it because, just then, he received a very definite impression of the opposite feeling; the agent was eating lunch of some sort, and enjoying it. There was no doubt about this. All that Smith could do was to wish, for the hundredth time, that he could look around a little and see what was being eaten, and how.

The meal occupied several minutes. Not once did the strange occupant of that machine relax his stony stare at the sky, and Smith tried to forget how hungry he was by estimating the extent of his vision. He decided that the angle subtended about a hundred and sixty degrees, or almost half a circle; and he further concluded that if his agent possessed a nose, it was a pretty trifling affair, too small to be noticed. It was obvious, too, that the fellow's mouth was located much lower in the face than normal. He ate without showing a single particle of food, and did it very quietly.

At length hunger was satisfied. There was complete stillness and silence for a moment, then another short lurching journey through the cane; and next, with an abruptness that made the engineer's senses swim again, the fellow once more took to the air. The speed with which he "got away" was enough to make a motorcyclist, doing his best, seem to stand still.

It took time for Smith to regain his balance. When he did, the same unbroken expanse of sky once more met his gaze; but it was not long until, out of the corners of those unblinking eyes, he could make out bleary forms which shortly resolved themselves into mountain tops. It was odd, the way things suddenly flashed into full view. One second they would be blurred and unrecognizable; the next, sharply outlined and distinct as anything the engineer had ever seen. Yet, there seemed to be no change in the focus of those eyes. It wasn't as though they were telescopic, either. Not until long afterward did Smith understand the meaning of this.

The mountains grew higher and nearer. Before long it seemed as though the aircraft was entering some sort of a canon. Its sides were only sparsely covered with vegetation, and all of it was quite brown, as though the season were autumn. For the most part the surface was of broken rock and boulders.

Within a space of three or four minutes the engineer counted not less than ten buzzards. The unknown operator of the machine, however, paid no attention to them, but continued his extraordinary watch of the heavens. Smith began to wonder if the chap were not seated in an air-tight, sound-proof chamber, deep in the hull of some great aerial cruiser, with his eyes glued fast to a periscope. "Maybe a sky patrol," thought the man of the earth; "a cop on the lookout for aerial smugglers, like as not."

And then came another of those terrifying stops. This time, as soon as he could collect his senses, the engineer saw that the machine had landed approximately in the middle of the canon, and presumably among the boulders in its bottom. For all about it were the tops of gigantic rocks, most of them worn smooth from water action. And, as soon as the engine stopped, Smith plainly heard the roar of water right at hand. He could not see it, however. Why in the name of wonder didn't the fellow look down, for a change?

The craft began to move. This time its motion was smoother arguing an even surface. However, it had not gone far before, to the engineer's astonishment, it began to move straight down a slope so steep that no mechanism with which Smith was familiar could possibly have clung to it. As this happened, his adopted eyes told him that the craft was located upon one of those enormous boulders, in the center of a stream of such absolute immensity that he fairly gasped. The thing was—colossal!

And yet it was true. The unseen machine deliberately moved along until it was actually clinging, not to the top, but to the side of the rock. The water appeared to be about five yards beneath, to the right. To the left was the sky, while the center of that strange vision was now upon a similar boulder seemingly a quarter of a mile distant, farther out in the stream. But the fellow at the periscope didn't change position one whit!

It was so unreal. Smith deliberately ignored everything else and watched again for indications of eyelids. He saw not one flicker, but noticed a certain tiny come-and-go, the merest sort of vibration, which indicated the agent's heart-action. Apparently it beat more than twice as fast as Smith's.

But it relieved him to know that his agent was at least a genuine living being. For a moment he had fancied something utterly repellent to him. Suppose this Sanusian were not any form of natural creature at all, but some sort of supermachine, capable of functioning like an organism? The thought made the engineer shudder as no morgue could.

Presently the queer craft approached the water closely enough, and at such an angle, that Smith looked eagerly for a reflection. However, the water was exceedingly rough, and only a confused brownish blur could be made out. Once he caught a queer sound above the noise of the water; a shrill hiss, with a harsh whine at the end. "Just like some kind of suction apparatus," as he later described it.

And then, with that peculiar sound fresh in his ears, came the crowning shock of the whole experience. Floating toward the boulder, but some distance away, was what looked like a black seed. Next moment the vision flashed clear, as usual, and the engineer saw that the object was really a beetle; and in a second it was so near that Smith's own body, back on the earth, involuntarily shrank back into the recesses of his chair.

For that beetle was an enormity in the most unlimited sense of the word. It was infinitely larger than any beetle the engineer had ever seen—infinitely! It was as large as a good-sized horse!

But before Smith could get over his amazement there was a rush and a swirl in the water behind the insect. Spray was dashed over the rock, a huge form showed itself indistinctly beneath the waves, and next instant the borrowed eyes were showing the engineer, so clearly as to be undeniable, the most astounding sight he had ever seen.

A fish of mountainous size leaped from the water, snapped the beetle into its mouth, and disappeared from sight. In a flash it had come and gone, leaving the engineer fairly gasping and likewise wondering how he could possibly expect anybody to believe him if he told the bald truth of what he had seen.

For he simply could not have invented anything half as incredible. The fish simply could not be described with ordinary language. IT WAS AS LARGE AS THE LARGEST LOCOMOTIVE.



IV

THE GOLD-MINER



As for Van Emmon, his experience will have to be classed with Smith's. That is to say, he soon came to feel that his agent was not what is commonly called human. It was all too different. However, he found himself enjoying a field of view which was a decided improvement upon Smith's. Instead of a range which began and ended just above the horizon, his agent possessed the power of looking almost straight ahead.

This told the geologist that his unsuspecting Sanusian was located in an aircraft much like the other. The same tremendous noise of the engine, the same inexplicable wing action, together with the same total lack of the usual indications of human occupancy, all argued that the two men had hit upon the same type of agent. In Van Emmon's case, however, he could occasionally glimpse two loose parts of the machine, flapping and swaying oddly from time to time within the range of the observer, and at the front. Nothing was done about it. Van Emmon came to the same conclusion as Smith; the operator was looking into something like a periscope. Perhaps he himself did not do the driving.

From what the geologist could see of the country below, it was quite certainly cultivated. In no other way could the even rows and uniform growth be explained; even though Van Emmon could not say whether the vegetation were tree, shrub, or plant, it was certainly the work of man-or some-thing mightily like man.

Shortly he experienced an abrupt downward dive, such as upset his senses somewhat. When he recovered, he had time for only the swiftest glance at what, he thought rather vaguely, was a great green-clad mountain. Then his agent brought the craft to one of those nerve-racking stops; once more came a swimming of the brain, and then the geologist saw something that challenged his understanding.

The craft had landed on the rim of a deep pit, or what would have been called a pit if it had not been so extraordinary. Mainly the strangeness was a matter of color; the slope was of a brilliant orange, and seemingly covered with frost, for it sparkled so brightly in the sun as to actually hurt the eyes. In fact, the geologist's first thought was "A glacier," although he could not conceive of ice or snow of that tint.

Running down the sides of the pit were a number of dark-brown streaks, about a yard wide; Van Emmon could make them out, more or less clearly, on the other side of the pit as well. From the irregular way in which the walls were formed, he quickly decided that the pit was a natural one. The streaks, he thought, might have been due to lava flow.

His agent proceeded to drive straight over the rim and down the slope into the pit. His engine was quite stopped; like Smith, the geologist wondered just how the craft's wheels were operated. Next he was holding his breath as the machine reached so steep a point in the slope that, most surely, no brakes could hold it. Simultaneously he heard the hiss and whine which seemed to indicate the suction device.

"It was a whole lot like going down into a placer mine," the geologist afterward said; and in view of what next met his eyes, he was justified in his guess.

Down crept the machine until it was "standing on its nose." The sun was shining almost straight down into the slope, and Van Emmon forgot his uneasiness about the craft in his interest in what he saw.

The bottom of the pit was perhaps twenty feet in diameter, and roughly hemispherical. Standing up from its bottom were half a dozen slim formations, like idealized stalagmites; they were made of some semitransparent rock, apparently, the tint being a reddish yellow. Finally, perched on the top of each of these was a stone; and surrounding these six "landmarks," 'as Van Emmon called them, was the most prodigious display of wealth imaginable. For the whole queer place was simply sprinkled with gold. Gold—gold everywhere; large nuggets of it, as big as one's fist! Not embedded in rock, not scattered through sand, but lying loose upon the surface of that unbelievable orange snow! It was overwhelming.

The mysterious Sanusian lost no time. Operating some unseen machinery, he caused three shovel-like devices to project from the front of his machine; and these instantly proceeded, so swiftly that Van Emmon could not possibly watch their action, to pick up nuggets and stow them away out of sight in what must have been compartments in the hull. All this was done without any sound beyond the occasional thud of a nugget dropped in the scramble. Suddenly the Sanusian wheeled his machine about and started hurriedly up the slope. Van Emmon judged that the chap had been frightened by something, for he took flight as soon as he reached the top of the pit. And—he left half a million in gold behind him!

This new flight had not lasted two minutes before the geologist began to note other objects in the air. There were birds, so distant that he could not identify them; one came near enough, however, for him to conclude that it was a hawk. But he did not hold to this conclusion very long.

The thing that changed his mind was another aircraft. It approached from behind, making even more noise than the other, and proceeded to draw abreast of it. From time to time Van Emmon's agent turned his mysterious periscope so as to take it all in, and the geologist was able to watch his fill. Whereupon he became converted to a new idea: The birds that Smith and he had seen had not been birds at all, but aircraft built in imitation of them. For this new arrival had been made in almost perfect imitation of a bee! It was very close to an exact reproduction. For one exception, it did not have the hairy appearance so characteristic of bees; the body and "legs" were smooth and shiny. (Later, Van Emmon saw machines which went so far as even to imitate the hairs.) Also, instead of trying to duplicate the two compound eyes which are found, one on each side of a bee's head, a perfectly round representation of a single eye was built, like a conning tower, toward the front of the bow. Presumably, the observer sat or stood within this "head."

But otherwise it was wonderfully like a drone bee. Van Emmon was strongly reminded of what he had once viewed under a powerful lens. The fragile semitransparent wings, the misshapen legs, and even the jointed body with its scale-like segments, all were carefully duplicated on a large scale. Imagine a bee thirty feet long!

At first the geologist was puzzled to find that it carried a pair of many-jointed antennae. He could not see how any intelligent being would make use of them; they were continually waving about, much as bees wave theirs. Evidently these were the loose objects he had already noted. "Now," he wondered, "why in thunder did the builders go to so much trouble for the sake of mere realism?"

Then he saw that the antennae served a very real purpose. There was no doubt about it; they were wireless antennae!

For presently the newcomer, who so far had not shown himself at any point on his machine, sent out a message which was read as quickly as it was received by Van Emmon's agent, and as unconsciously translated:

"Number Eight Hundred Four, you are wanted on Plot Seventeen."

Whereupon Van Emmon's unknown assistant replied at once:

"Very well, Superior."

It was done by means of an extremely faint humming device, reminding the geologist of certain wireless apparata he had heard. Not a word was actually spoken by either Sanusian.

Van Emmon kept a close watch upon the conning tower on the other machine. The sun was shining upon it in such a fashion that its gleam made inspection very difficult. Once he fancied that he could make out a short, compact figure within the "eye"; but he could not be sure. The glass, or whatever it was, reflected everything within range.

Was the airman a quadruped? Did he sit or stand upright, like a man? Or did he use all four limbs, animal-fashion? Van Emmon had to admit that he could not tell; no wonder he didn't guess the truth.

Shortly after receiving the summons, the geologist's agent changed his direction slightly; and within ten minutes the machine was passing over a large grain field. On the far edge was a row of trees, and it was toward this that the Sanusian proceeded to volplane, presently coming to another nausea-producing stop. Once more Van Emmon was temporarily helpless.

When he could look again, he saw that the machine had landed upon a steep slope, this time with its nose pointing upward. Far above was what looked like a cave, with a growth of some queer, black grass on its upper rim. The craft commenced to move upward, over a smooth, dark tan surface.

In half a minute the machine had reached the top of the slope, and the geologist looked eagerly for what might lie within the cave. He was disappointed; it was not a cave at all. Instead, another brown slope, or rather a bulging precipice, occupied this depression.

Van Emmon looked closer. At the bottom of this bulge was a queer fringe of the same kind of grass that showed on top of it. Van Emmon looked from one to the other, and all of a sudden the thing dawned upon him.

This stupendous affair was no mountainside; it was neither more nor less than the head of a colossal statue! A mammoth edition of the Goddess of Liberty; and the aircraft had presumed to alight upon its cheek!

The machine clung there, motionless, for some time, quite as though the airman knew that Van Emmon would like to look a long while. He gazed from side to side as far as he could see, making out a small section of the nose, also the huge curves of a dust-covered ear. It was wonderfully life-like.

Next second came the earthquake. The whole statue rocked and swayed; Van Emmon looked to see the machine thrown off. From the base of the monument came a single terrific sound, a veritable roar, as though the thing was being wrenched from the heart of the earth. From somewhere on top came a spurt of water that splashed just beside the craft.

Then came the most terrible thing. Without the slightest warning the statue's great eye opened! Opened wide, revealing a prodigious pupil which simply blazed with wrath!

The statue was alive!

Next second the Sanusian shot into the air. A moment and Van Emmon was able to look again, and as it happened, the craft was now circling the amazing thing it had just quit, so that the geologist could truthfully say that he was dead sure of what he saw.

He was justified in wanting to be absolutely sure. Resting on the solid earth was a human head, about fifty yards wide and proportionately as tall. It was alive; but IT WAS ONLY THE HEAD, NOTHING MORE.



V

THE SUPER-RACE



It will be remembered that Billie wanted to get in touch with a creature having the characteristic which she had said she admired: supremacy—"A worker who is the boss!" Bearing this in mind, her experience will explain itself, dumfounding though it was.

Her first sight of the Sanusian world was from the front of a large building. The former architect was not able to inspect it minutely; but she afterwards said that it impressed her as being entirely plain, and almost a perfect cube. Its walls were white and quite without ornament; there was only one entrance, an extremely low and broad, flat archway, extending across one whole side. The structure was about a hundred yards each way. In front was a terrace, seemingly paved with enormous slabs of stone; it covered a good many acres.

Presumably Billie's agent had just brought her machine from the building, for, within a few seconds, she took flight in the same abrupt fashion which had so badly upset Smith and Van Emmon. When Billie was able to look closely, she found herself gazing down upon a Sanusian city.

It was a tremendous affair. As the flying-machine mounted higher, Billie continually revised her guesses; finally she concluded that London itself was not as large. Nevertheless her astonishment was mainly directed at the character, not the number of the buildings.

They were all alike! Every one was a duplicate of that she had first seen: cube-shaped, plain finished, flat of wall and roof. Even in color they were alike; in time the four came to call the place the "White City." However, the buildings were arranged quite without any visible system. And they were vastly puzzled, later on in their studies, to find every other Sanusian city precisely the same as this one.

However, there was one thing which distinguished each building from the rest. It was located on the roof; a large black hieroglyphic, set in a square black border, which Billie first thought to be all alike. Whether it meant a name or a number, there was no way to tell.[Footnote: Since writing the above, further investigations have proved that these Sanusian house-labels are all numbers.]

Billie turned her attention to her agent. She seemed to belong to the same type as Smith's and Van Emmon's; otherwise she was certainly much more active, much more interested in her surroundings, and possessed of a far more powerful machine. She was continually changing her direction; and Billie soon congratulated herself upon her luck. Beyond a doubt, this party was no mere slave to orders; it was she who gave the orders.

Before one minute had passed she was approached by a Sanusian in a big, clumsy looking machine. Although built on the bee plan, it possessed an observation tower right on top of its "head." (The four afterward established that this was the sort of a machine that Smith's agent had operated.) The occupant approached to within a respectful distance from Billie's borrowed eyes, and proceeded to hum the following through his antennae:

"Supreme, I have been ordered to report for Number Four."

"Proceed."

"The case of insubordinancy which occurred in Section Eighty-five has been disposed of."

"Number Four made an example of her?"

"Yes, Supreme."

Whereupon the operator flew away, having not only kept his body totally out of sight all the while, but having failed by the slightest token to indicate, by his manner of communicating that he had the slightest particle of personal interest in his report. For that matter, neither did Supreme.

Scarcely had this colloquy ended than another subordinate approached. This one used a large and very fine machine. She reported:

"If Supreme will come with me to the spot, it will be easier to decide upon this case."

Immediately the two set off without another word; and after perhaps four minutes of the speediest travel Billie had known outside the doctor's sky-car, they descended to within a somewhat short distance from the ground. Here they hovered, and Billie saw that they were stopped above some hills at the foot of a low mountain range.

Next moment she made out the figures of four humans on top of a knoll just below. A little nearer, and the architect was looking, from the air, down upon the same scene which the doctor was then witnessing through the eyes of Rolla, the older of the two Sanusian women. Billie could make out the powerful physique of Corrus, the slighter figure of Dulnop, the small but vigorous form of Cunora, and Rolla's slender, graceful, capable body. But at that moment the other flier began to say to Supreme:

"The big man is a tender of cattle, Supreme; and he owes his peculiar aptitude to the fact that his parents, for twenty generations back, were engaged in similar work. The same may be said for the younger of the two women; she is small, but we owe much of the excellence of our crops to her energy and skill.

"As for the other woman," indicating Rolla, "she is a soil-tester, and very expert. Her studies and experiments have greatly improved our product. The same may be said in lesser degree of the youth, who is engaged in similar work."

"Then," coolly commented the Sanusian whose eyes and ears Billie enjoyed; "then your line of action is clear enough. You will see to it that the big man marries the sturdy young girl, of course; their offspring should give us a generation of rare outdoor ability. Similarly the young man and the older woman, despite their difference in ages, shall marry for the sake of improving the breed of soil-testers."

"Quite so, Supreme. There is one slight difficulty, however, such as caused me to summon you."

"Name the difficulty."

The Sanusian hesitated only a trifle with her reply: "It is, Supreme, that the big man and the older woman have seen fit to fall in love with one another, while the same is true of the youth and the girl."

"This should not have been allowed!"

"I admit it, Supreme; my force has somehow overlooked their case, heretofore. What is your will?"

The commandant answered instantly: "Put an immediate end to their desires!"

"It shall be done!"

At that moment there was a stir on the ground. In fact, this was the instant when Corrus began his vehement outcry against the tyranny of "They." The two in the air came closer; whereupon Billie discovered that Supreme did not understand the language of the humans below. [Footnote: The humans did not realize this fact, however; they assumed that "They" always understood.] Yet the herdsman's tones were unmistakably angry.

"You will descend," commented Supreme evenly, "and warn the big man not to repeat such outbreaks."

Immediately Supreme's lieutenant darted down, and was lost to view. The commandant glanced interestedly here and there about the landscape, returning her gaze to Corrus just as the man stopped in mid-speech. Billie was no less astonished than the doctor to see the herdsman's expression change as it did; one second it was that of righteous indignation, the next, of the most abject subservience.

Nevertheless, Billie could see no cause whatever for it; neither did she hear anything. The other flier remained out of sight. All that the architect could guess was that the operator had "got the drop" on Corrus in some manner which was clear only to those involved. Badly puzzled, Billie watched the four humans hurry away, their manner all but slinking.

A moment later still another aircraft came up, and its operator reported. As before, Billie could make out not a single detail of the occupant herself. She, too, wanted the commandant's personal attention; and shortly Billie was looking down upon a scene which she had good reason to remember all the rest of her life.

In the middle of a large field, where some light green plant was just beginning to sprout, a group of about a dozen humans was at work cultivating. Billie had time to note that they were doing the work in the most primitive fashion, employing the rudest of tools, all quite in keeping with their bare heads and limbs and their skin-clad bodies. About half were women.

Slightly at one side, however, stood a man who was not so busy. To put it plainly, he was loafing, with the handle of his improvised mattock supporting his weight. Clearly the two up in the air were concerned only with him.

"He has been warned three times, Supreme," said the one who had reported the case.

"Three? Then make an example of him!"

"It shall be done, Supreme!"

The lieutenant disappeared. Again the commandant glanced at this, that, and the other thing before concentrating upon what happened below. Then Billie saw the man straighten up suddenly in his tracks, and with remarkable speed, considering his former laziness, he whirled about, dodged, and clapped a hand upon his thigh.

Next second he raised an exultant cry. Billie could not understand what he said; but she noted that the others in the group echoed the man's exultation, and started to crowd toward him, shouting and gesticulating in savage delight. Then something else happened so sudden and so dreadful that the woman who was watching from the earth was turned almost sick.

Like a flash Supreme dropped, headlong, toward the group of humans. In two seconds the distance was covered, and in the last fifth of a second Billie saw the key to the whole mystery.

In that last instant the man who before had seemed of ordinary size, was magnified to the dimensions of a colossus. Instead of being under six feet, he appeared to be near a hundred yards in height; but Billie scarcely realized this till later, it all happened so quickly. There was an outcry from the group, and then the commandant's aircraft crashed into the man's HAND; a hand so huge that the very wrinkles in its skin were like so many gulleys; even in that final flash Billie saw all this.

Simultaneously with the landing there was a loud pop, while Billie's senses reeled with the stunning suddenness of the impact. Next second the machine had darted to a safe distance, and Billie could see the man gnawing frantically at the back of his hand. Too late; his hand went stiff, and his arm twitched spasmodically. The fellow made a step or two forward, then swayed where he stood, his whole body rigid and strained. An expression of the utmost terror was upon his face; he could not utter a sound, although his companions shrieked in horror. Another second and the man fell flat, twitching convulsively; and in a moment or two it was all over. He was dead!

And then the truth burst upon the watcher. In fact, it seemed to come to all four at the same time, probably by reason of their mental connections. Neither of them could claim that he or she had previously guessed a tenth of its whole, ghastly nature.

The "cane" which Smith had seen had not been cane at all; it had been grass. The "beetle" in the stream had not been the giant thing he had visualized it; neither had that fish been the size he had thought.

Van Emmon's "gold mine" had not been a pit in any sense of the word; it had been the inside of the blossom of a very simple, poppy-like flower. The "nuggets" had been not mineral, but pollen. As for the incredible thing which Van Emmon had seen on the ground; that living statue; that head without a body—the body had been buried out of sight beneath the soil; and the man had been an ordinary human, being punished in this manner for misconduct.

Instead of being aircraft built in imitation of insects, the machines had been constructed by nature herself, and there had been nothing unusual in their size. No; they were the real thing, differing only slightly from what might have been found anywhere upon the earth.

In short, it had all been simply a matter of view-point. The supreme creature of Sanus was, not the human, but the bee. A poisonous bee, superior to every other form of Sanusian life! What was more—

"The damned things are not only supreme; THE HUMANS ARE THEIR SLAVES!"



VI



Impossible, But—

The four looked at each other blankly. Not that either was at a loss for words; each was ready to burst. But the thing was so utterly beyond their wildest conceptions, so tremendously different in every way, it left them all a little unwilling to commit themselves.

"Well," said Smith finally, "as I said in the first place, I can't see how any other than the human form became supreme. As I understand biology—"

"What gets me," interrupted Van Emmon; "what gets me is, WHY the humans have allowed such an infernal thing to happen!"

Billie smiled somewhat sardonically. "I thought," she remarked, cuttingly, "that you were always in sympathy with the upper dog, Mr. Van Emmon!"

"I am!" hotly. Then, with the memory of what he had just seen rushing back upon him: "I mean, I was until I saw—saw that—" He stopped, flushing deeply; and before he could collect himself Smith had broken in again:

"I just happened to remember, doc; didn't you say that the Venusians, in those books of yours, say that Sanus is ruled by the workers?"

"Just what I was wondering about," from Van Emmon. "The humans seem to do all the work, and the bees the bossing!"

The doctor expected this. "The Venusians had our viewpoint—the viewpoint of people on the earth, when they said that the workers rule. We consider the bee as a great worker, don't we? 'As busy as a bee,' you know. None of the so-called lower animals show greater industry."

"You don't mean to say," demanded Smith, "that these Sanusian bees owe their position to the fact that they are, or were, such great workers?"

Before the doctor could reply, Van Emmon broke in. It seemed as though his mind refused to get past this particular point. "Now, why the dickens have the humans allowed the bees to dominate them? Why?"

"We'll have to go at this a little more systematically," remarked Kinney, "if we want to understand the situation."

"In the first place, suppose we note a thing or two about conditions as we find them here on the earth. We, the humans, are accustomed to rank ourselves far above the rest. It is taken for granted.

"Now, note this: the human supremacy was not always taken for granted." He paused to let it sink in. "Not always. There was a time in prehistoric days when man ranked no higher than others. I feel sure of this," he insisted, seeing that Smith was opposed to the idea; "and I think I know just what occurred to make man supreme."

"What?" from Billie.

"Never mind now. I rather imagine we shall learn more on this score as we go on with our work.

"At any rate, we may be sure of this: whatever it was that caused man to become supreme on the earth, that condition is lacking on Sanus!"

Van Emmon did not agree to this. "The condition may be there, doc, but there is some other factor which overbalances it; a factor such as is—well, more favorable to the bees."

The doctor looked around the circle. "What do you think? 'A factor more favorable to the bees.' Shall we let it go at that?" There was no remark, even from Smith; and the doctor went an:

"Coming back to the bees, then, we note that they are remarkable for several points of great value. First, as we have seen, they are very industrious by nature. Second, all bees possess wings and on that count alone they are far superior to humans.

"Third—and to me, the most important—the bees possess a remarkable combination of community life and specialization. Of course, when you come to analyze these two points, you see that they really belong to one another. The bees we know, for instance, are either queens, whose only function is to fertilize the eggs; or workers, who are unsexed females, and whose sole occupations are the collecting of honey, the building of hives, and the care of the young.

"Now," speaking carefully, "apparently these Sanusian bees have developed something that is not unknown to certain forms of earth's insect life. I mean, a soldier type. A kind of bee which specializes on fighting!"

Van Emmon was listening closely, yet he had got another idea: "Perhaps this soldier type is simply the plain worker bee, all gone to sting! It may be that these bees have given up labor altogether!"

"Still," muttered Smith, under his breath, "all this doesn't solve the real problem. Why aren't the HUMANS supreme?" For once he became emphatic. "That's what gets me! Why aren't the humans the rulers, doc?" Kinney waited until he felt sure the others were depending upon him. "Smith, the humans on Sanus are not supreme now because they were NEVER supreme."

Smith looked blank. "I don't get that."

"Don't you? Look here: you'll admit that success begets success, won't you?"

"Success begets success? Sure! 'Nothing succeeds like success.'"

"Well, isn't that merely another way of saying that the consciousness of superiority will lead to further conquests? We humans are thoroughly conscious of our supremacy; if we weren't we'd never attempt the things we do!"

Van Emmon saw the point. "In other words, the humans on the earth never began to show their superiority until something—something big, happened to demonstrate their ability!"

"Exactly!" cried Kinney. "Our prehistoric ancestors would never have handed down such a tremendous ambition to you and me if they, at that time, had not been able to point to some definite feat and say, 'That proves I'm a bigger man than a horse,' for example."

"Of course," reflected Billie, aloud; "of course, there were other factors."

"Yes; but they don't alter the case. Originally the human was only slightly different from the apes he associated with. There was perhaps only one slight point of superiority; today there are millions of such points. Man is infinitely superior, now, and it's all because he was slightly superior, then."

"Suppose we grant that," remarked the geologist. "What then? Does that explain why the bees have made good on Sanus?"

"To a large degree. Some time in the past the Sanusian bee discovered that he possessed a certain power which enabled him to force his will upon other creatures. This power was his poisonous sting. He found that, when he got his fellows together and formed a swarm, they could attack any animal in such large numbers as to make it helpless."

"Any creature?"

"Yes; even reptiles, scales or no scales. They'd attack the eyes."

"But that doesn't explain how the bees ever began to make humans work for them," objected Van Emmon.

The doctor thought for a few minutes. "Let's see. Suppose we assume that a certain human once happened to be in the neighborhood of a hive, just when it was attacked by a drove of ants. Ants are great lovers of honey, you know. Suppose the man stepped among the ants and was bitten. Naturally he would trample them to death, and smash with his hands all that he couldn't trample. Now, what's to prevent the bees from seeing how easily the man had dealt with the ants? A man would be far more efficient, destroying ants, than a bee; just as a horse is more efficient, dragging a load, than a man. And yet we know that the horse was domesticated, here on the earth, simply because the humans saw his possibilities; the horse could do a certain thing more efficiently than a human.

"You notice," the doctor went on, with great care, "that everything I've assumed is natural enough: the combination of an ant attack and the man's approach, occurring at the same time. Suppose we add a third factor: that the bees, even while fighting the ants, also started to attack the man; but that he chanced to turn his attention to the ants FIRST. So that the bees let him alone!

"We know what remarkable things bees are, when it comes to telling one another what they know. Is there any reason why such an experience—all natural enough—shouldn't demonstrate to them that they, by merely threatening a man, could compel him to kill ants for them?"

Billie was dubious for a moment; then agreed that the man, also, might notice that the bees failed to sting him as long as he continued to destroy their other enemies. If so, it was quite conceivable that, bit by bit, the bees had found other and more positive ways of securing the aid of men through threatening to sting. "Even to cultivating flowers for their benefit," she conceded. "It's quite possible."

Smith had been thinking of something else. "I always understood that a bee's stinging apparatus is good for only one attack. Doesn't it always remain behind after stinging?"

"Yes," from the doctor, quietly. "That is true. The sting has tiny barbs on its tip, and these cause it to remain in the wound. The sting is actually torn away from the bee when it flies away. It never grows another. That is why, in fact, the bee never stings except as a last resort, when it thinks it's a question of self-defense."

"Just what I thought!" chuckled Smith. "A bee is helpless without its sting! If so, how can you account for anything like a soldier bee?"

The doctor returned his gaze with perfect equanimity. He looked at Van Emmon and Billie; they, too, seemed to think that the engineer had found a real flaw in Kinney's reasoning. The doctor dropped his eyes, and searched his mind thoroughly for the best words. He removed his bracelets while he was thinking; the others did the same. All four got to their feet and stretched, silently but thoroughly. Not until they were ready to quit the study did the doctor make reply.

"Smith, I don't need to remind you that it's the little things that count. It's too old a saying. In this case it happens to be the greatest truth we have found today.

"Smith"—speaking with the utmost care—"what we have just said about the bee's sting is all true; but only with regard to the bees on the earth. It is only on the earth, so far as we know positively, that the bee is averse to stinging, for fear of losing his sting.

"There is only one way to account for the soldier bee. Its sting has no barbs!"

"No barbs?"

"Why not? If the poison is virulent enough, the barbs wouldn't be necessary, would they? Friends, the Sanusian bee is the supreme creature on its planet; it is superior to all the other insects, all the birds, all the animals; and its supremacy is due solely and entirely to the fact that there are no barbs on its sting!"



VII

THE MISSING FACTOR



By the time the four once more got together in the doctor's study, each had had a chance to consider the Sanusian situation pretty thoroughly. All but Billie were convinced that the humans were deserving people, whose position was all the more regrettable because due, so far as could be seen, the insignificant little detail of the barbless sting.

Were these people doomed forever to live their lives for the sake of insects? Were they always to remain, primitive and uncultured, in ignorance of the things that civilization is built upon, obeying the orders of creatures who were content to eat, reproduce, and die? For that is all that bees know!

Perhaps it was for the best. Possibly Rolla and her friends were better off as they were. It might have been that a wise Providence, seeing how woefully the human animal had missed its privileges on other worlds, had decided to make man secondary on Sanus. Was that the reason for it all?

All but Billie scouted the idea. To them the affair was a ghastly perversion of what Nature intended. Van Emmon stated the case in a manner which showed how strongly he felt about it.

"Those folks will never get anywhere if the bees can help it!" he charged." We've got to lend a hand, here, and see that they get a chance!"

Smith said that, so far as he was concerned, the bees might all be consigned to hell. "I'm not going to have anything to do with the agent I had, any more!" he declared. "I'm going to get in touch with that chap, Dulnop. What is he like, doc?"

Kinney told him, and then Van Emmon asked for details of the herdsman, Corrus. "No more bees in my young life, either. From now on it's up to us. What do you think?" turning to his wife, and carefully avoiding any use of her name.

The architect knew well enough that the rest were wondering how she would decide. She answered with deliberation:

"I'm going to stay in touch with Supreme!"

"You are!" incredulously, from her husband.

"Yes! I've got a darned sight more sympathy for those bees than for the humans! The 'fraid-cats!" disgustedly.

"But listen," protested Van Emmon. "We can't stand by and let those cold-blooded prisoners keep human beings, like ourselves, in rank slavery! Not much!"

Evidently he thought he needed to explain. "A human is a human, no matter where we find him! Why, how can those poor devils show what they're good for if we don't give 'em a chance? That's the only way to develop people—give 'em a chance to show what's in 'em! Let the best man win!"

Billie only closed her mouth tighter; and Smith decided to say, "Billie, you don't need to stand by your guns just because the Sanusian working class happens to be insects. Besides, we're three to one in favor of the humans!"

"Oh, well," she condescended, "if you put it that way I'll agree not to interfere. Only, don't expect me to help you any with your schemes; I'll just keep an eye on Supreme, that's all."

"Then we're agreed." The doctor put on his bracelets. "Suppose we go into the trance state for about three minutes—long enough to learn what's going on today."

Shortly Billie again using the eyes and ears of the extraordinarily capable bee who ruled the rest, once more looked down upon Sanus. She saw the big "city," which she now knew to be a vast collection of hives, built by the humans at the command of the bees. At the moment the air was thick with workers, returning with their loads of honey from the fields which the humans had been compelled to cultivate. What a diabolical reversal of the accepted order of things!

The architect had time to note something very typical of the case. On the outskirts of the city two humans were at work, erecting a new hive. Having put it together, they proceeded to lift the big box and place it near those already inhabited. They set it down in what looked like a good location, but almost immediately took it up again and shifted it a foot to one side. This was not satisfactory, either; they moved it a few inches in another direction.

All told, it took a full minute to place that simple affair where it was wanted; and all the while those two humans behaved as though some one were shouting directions to them—silent directions, as it were. Billie knew that a half-dozen soldier bees, surrounding their two heads, were coolly and unfeelingly driving them where they willed. And when, the work done, they left the spot, two soldiers went along behind them to see that they did not loiter.

As for the doctor, he came upon Rolla when the woman was deep in an experiment. She stood in front of a rude trough, one of perhaps twenty located within a large, high-walled inclosure. In the trough was a quantity of earth, through the surface of which some tiny green shoots were beginning to show.

Rolla inspected the shoots, and then, with her stone knife, she made a final notch in the wood on the edge of the trough. There were twenty-odd of these notches; whereas, on other troughs which the doctor had a chance to see, there were over thirty in many cases, and still no shoots.

The place, then, was an experimental station. This was proven by Rolla's next move. She went outside the yard and studied five heaps of soil, each of a different appearance, also three smaller piles of pulverized mineral—nitrates, for all that the doctor knew. And before Kinney severed his connection with the Sanusian, she had begun the task of mixing up a fresh combination of these ingredients in a new trough. In the midst of this she heard a sound; and turning about, waved a hand excitedly toward a distant figure on the far side of a nearby field.

Meanwhile Smith had managed to get in touch with Dulnop. He found the young man engaged in work which did not, at first, become clear to the engineer. Then he saw that the chap was simply sorting over big piles of broken rock, selecting certain fragments which he placed in separate heaps. Not far away two assistants were pounding these fragments to powder, using rude pestles, in great, nature-made mortars—"pot-holes," from some river-bed.

It was this powder, beyond a doubt, that Rolla was using in her work. To Smith, Dulnop's task seemed like a ridiculously simple occupation for a nearly grown man, until he reflected that these aborigines were exactly like toddling children in intellects.

Van Emmon had no trouble in making connections with Corrus. The herdsman was in charge of a dozen cows, wild looking creatures which would have been far too much for the man had they been horned, which they were not. He handled them by sheer force, using the great club he always carried. Once while Van Emmon was watching, a cow tried to break away from the group; but Corrus, with an agility amazing in so short and heavy a man, dashed after the creature and tapped her lightly on the top of her head. Dazed and contrite, she followed him meekly back into the herd.

The place was on the edge of a meadow, at the beginning of what looked like a grain field. Stopping here, Corrus threw a hand to his mouth and gave a ringing shout. Immediately it was answered, faintly, by another at a distance; and then Van Emmon made out the form of Rolla among some huts on the other side of the grain. She beckoned toward the herdsman, and he took a half-dozen steps toward her.

Just as abruptly he stopped, almost in mid-stride. Simultaneously Van Emmon heard a loud buzzing in either ear. Corrus was being warned. Like a flash he dropped his head and muttered: "Vey well. I will remember—next time." And trembling violently he turned back to his cows.

"Well," remarked the geologist, when the four "came out" of their seance, "the bees seem to have everything their own way. How can we help the humans best? Hurry up with your idea; I'm getting sick of these damned poisoners."

The doctor asked if the others had any suggestions. Smith offered this: why couldn't the humans retire to some cave, or build tight-walled huts, and thus bar out the bees?

No sooner had he made the remark, however, than the engineer declared his own plan no good. "These people aren't like us; they couldn't stand such imprisonment long enough to make their 'strike' worth while."

"Is there any reason," suggested Billie, indifferently, "why they couldn't weave face nets from some kind of grass, and protect themselves in that way?"

Smith saw the objection to that, too. "They'd have to protect themselves all over as well; every inch would have to be covered tightly. From what I've seen of them I'd say that the arrangement would drive them frantic. It would be worse than putting clothes on a cat."

"It's a man-sized job we've tackled," commented the doctor. "What Smith says is true; such people would never stand for any measures which would restrict their physical freedom. They are simply animals with human possibilities, nothing more."

He paused, and then added quietly, "By the way, did either of you notice any mountains just now?"

Smith and Van Emmon both said they had. "Why?"

"Of course, it isn't likely, but—did you see anything like a volcano anywhere?"

"No," both replied.

"Another thing," Kinney went on. "So far, I've seen nothing that would indicate lightning, much less the thing itself. Did either of you," explicitly, "run across such a thing as a blasted tree?"

They said they had not. Billie hesitated a little with her reply, then stated that she had noted a tree or two in a state of disintegration, but none that showed the unmistakable scars due to being struck by lightning.

"Then we've got the key to the mystery!" declared the doctor. "Remember how brown and barren everything looks excepting only where there's artificial vegetation? Well, putting two and two together, I come to the conclusion that Sanus differs radically from the earth in this respect:

"The humans have arrived rather late in the planet's history. Or—and this is more likely—Sanus is somewhat smaller than the earth, and therefore has cooled off sooner. At any rate, the relationship between the age of the planet and the age of its human occupancy differs from what it is on the earth."

"I don't quite see," from Smith, "what that's got to do with it."

"No? Well, go back to the first point: the dried-up appearance of things. That means, their air and water are both less extensive than with us, and for that reason there are far fewer clouds; therefore, it is quite possible that there has been no lightning within the memory of the humans."

"How so?" demanded the geologist.

"Why, simply because lightning depends upon clouds. Lightning is merely the etheric electricity, drawn to the earth whenever there is enough water in the air to promote conductivity."

"Yes," agreed Smith; "but—what of it?"

Kinney went on unheeding. "As for volcanoes—probably the same explanation accounts for the lack of these also. You know how the earth, even, is rapidly coming to the end of her Volcanic period. Time was when there were volcanoes almost everywhere on the earth.

"The same is likely true of Sanus as well. The point is," and the doctor paused significantly, "there have been no volcanic eruptions, and no lightning discharges within the memory of Sanusian man!"

What was he getting at? The others eyed him closely. Neither Van Emmon nor Smith could guess what he meant; but Billie, her intuition wide awake, gave a great jump in her chair.

"I know!" she cried. A flood of light came to her face.

"The Sanusians—no wonder they let the bees put it over on them!"

"They haven't got FIRE! They've never had it!"



VIII

FIRE!



From the corner of his eyes Kinney saw Van Emmon turn a gaze of frank admiration at his wife. It lasted only a second, however; the geologist remembered, and masked the expression before Billie could detect it.

Smith had been electrified by the idea.

"By George!" he exclaimed two or three times. "Why didn't I think of that? It's simple as A, B, C now!"

"Why," Van Emmon exulted, "all we've got to do is put the idea of fire into their heads, and the job is done!" He jumped around in his chair. "Darn those bees, anyhow!"

"And yet," observed the doctor, "it's not quite as simple as we may think. Of course it's true that once they have fire, the humans ought to assert themselves. We'll let that stand without argument."

"Will we?" Smith didn't propose to back down that easy. "Do you mean to say that fire, and nothing more than fire, can bring about human ascendency?"

The doctor felt sure. "All the other animals are afraid of fire. Such exceptions as the moth are really not exceptions at all; the moth is simply driven so mad by the sight of flame that it commits suicide in it. Horses sometimes do the same.

"Humans are the only creatures that do not fear fire! Even a tiny baby will show no fear at the sight of it."

"Which ought to prove," Van Emmon cut in to silence Smith, "that superiority is due to fire, rather than fire due to superiority, for the simple reason that a newborn child is very low in the scale of evolution." Smith decided not to say what he intended to say. Van Emmon concluded:

"We've just got to give 'em fire! What's the first step?"

"I propose," from the doctor, "that when we get in touch this time we concentrate on the idea of fire. We've got to give them the notion first."

"Would you rather," inquired Billie, "that I kept the idea from Supreme?"

"Thanks," returned her husband, icily, "but you might just as well tell her, too. It'll make her afraid in advance, all the better!"

The engineer threw himself back in his seat. "I'm with you," said he, laying aside his argument. The rest followed his example, and presently were looking upon Sanus again.

All told, this particular session covered a good many hours. The four kept up a more or less connected mental conversation with each other as they went along, except, of course, when the events became too exciting. Mainly they were trying to catch their agents in the proper mood for receiving telepathic communications, and it proved no easy matter. It required a state of semi-consciousness, a condition of being neither awake nor asleep. It was necessary to wait until night had fallen on that particular part of the planet. [Footnote: It should be mentioned that all parts of Sanus showed the same condition of bee supremacy and human servitude. The spot in question was quite typical of all the colonies.]

Van Emmon was the first to get results. Corrus had driven his herd back from the brook at which they had got their evening drink, and after seeing them all quietly settled for the night, he lay down on the dried grass slope of a small hill, and stared up at the sky. Van Emmon had plenty of time to study the stars as seen from Sanus, and certainly the case demanded plenty of time.

For he saw a broad band of sky, as broad as the widest part of the Milky Way, which was neither black nor sparkling with stars, but glowing as brightly as the full moon! From the eastern horizon to the zenith it stretched, a great "Silvery Way," as Van Emmon labeled it; and as the darkness deepened and the night lengthened, the illumination crept on until the band of light stretched all the way across. Van Emmon racked his brains to account for the thing.

Then Corrus became drowsy. Van Emmon concentrated with all his might. At first he overdid the thing; Corrus was not quite drowsy enough, and the attempt only made him wakeful. Shortly, however, he became exceedingly sleepy, and the geologist's chance came.

At the end of a few minutes the herdsman sat up, blinking. He looked around at the dark forms of the cattle, then up at the stars; he was plainly both puzzled and excited. He remained awake for hours, in fact, thinking over the strange thing he had seen "in a dream."

Meanwhile Smith was having a similar experience with Dulnop. The young fellow was, like Corrus, alone at the time; and he, too, was made very excited and restless by what he saw.

Billie was unable to work upon her bee. Supreme retired to a hive just before dusk, but remained wide awake and more or less active, feeding voraciously, for hours upon hours. When she finally did nap, she fell asleep on such short notice that the architect was taken off her guard. The bee seemed to all but jump into slumberland.

The doctor also had to wait for Rolla. The woman sat for a long time in the growing dusk, looming out pensively over the valley. Corrus was somewhere within a mile or two, and so Kinney was not surprised to see the herdsman's image dancing, tantalizingly, before Rolla's eyes. She was thinking of him with all her might.

Presently she shivered with the growing coolness, and went into a rough hut, which she shared with Cunora. The girl was already asleep on a heap of freshly gathered brush. Rolla, delightfully free of any need to prepare for her night's rest—such as locking any doors or cleaning her teeth—made herself comfortable beside her friend. Two or three yawns, and the doctor's chance came.

Two minutes later Rolla sat bolt upright, at the same time giving out a sharp cry of amazement and alarm. Instantly Cunora awoke.

"What is it, Rolla?" terror-stricken.

"Hush!" The older woman got up and went to the opening which served as a door. There she hung a couple of skins, arranging them carefully so that no bee might enter. Coming back to Cunora, she brought her voice nearly to a whisper:

"Cunora, I have had a wonderful dream! Ye must believe me when I say that it were more than a mere dream; 'twere a message from the great god, Mownoth, or I be mad!"

"Rolla!" The girl was more anxious than frightened now. "Ye speak wildly! Quiet thyself, and tell what thou didst see!

"It were not easy to describe," said Rolla, getting herself under control. "I dreamed that a man, very pale of face and most curiously clad, did approach me while I was at work. He smiled and spake kindly, in a language I could not understand; but I know he meant full well.

"This be the curious thing, Cunora: He picked up a handful of leaves from the ground and laid them on the trough at my side. Then, from some place in his garments he produced a tiny stick of white wood, with a tip made of some dark-red material. This he held before mine eyes, in the dream; and then spake very reassuringly, as though bidding me not to be afraid.

"Well he might! Cunora, he took that tiny stick in his hand and moved the tip along the surface of the trough; and, behold, a miracle!"

"What happened?" breathlessly.

"In the twinkling of an eye, the stick blossomed! Blossomed, Cunora, before mine eyes! And such a blossom no eye ever beheld before. Its color was the color of the poppy, but its shape—most amazing! Its shape continually changed, Cunora; it danced about, and rose and fell; it flowed, even as water floweth in a stream, but always upward!"

"Rolla!" incredulously. "Ye would not awaken me to tell such nonsense!"

"But it were not nonsense!" insisted Rolla. "This blossom was even as I say: a living thing, as live as a kitten! And as it bloomed, behold, the stick was consumed! In a moment or two the man dropped what was left of it; I stooped—so it seemed—to pick it up; but he stopped me, and set his foot upon the beautiful thing!"

She sighed, and then hurried on. "Saying something further, also reassuring, this angel brought forth another of the strange sticks; and when he had made this one bloom, he touched it to the little pile of leaves. Behold, a greater miracle, Cunora! The blossoms spread to the leaves, and caus'ed them to bloom, too!"

Cunora was eying her companion pretty sharply. "Ye must take me for a simple one, to believe such imagining."

Rolla became even more earnest. "Yet it were more than imagining, Cunora; 'twere too vivid and impressive for only that. As for the leaves, the blossoming swiftly spread until it covered every bit of the pile; and I tell thee that the bloom flowed as high as thy hand! Moreover, after a moment or so, the thing faded and died out, just as flowers do at the end of the season; all that was left of the leaves was some black fragments, from which arose a bluish dust, like unto the cloud that ye and I saw in the sky one day.

"Then the stranger smiled again, and said something of which I cannot tell the meaning. Once more he performed the miracle, and this time he contrived to spread the blossom from some leaves to the tip of a large piece of wood which he took from the ground. 'Twas a wonderful sight!

"Nay, hear me further," as Cunora threw herself, with a grunt of impatience, back on her bed; "there is a greater wonder to tell.

"Holding this big blooming stick in one hand, he gave me his other; and it seemed as though I floated through the air by his side. Presently we came to the place where Corrus's herd lay sleeping. The angel smote one of the cows with the flat of his hand, so that it got upon its feet; and straighway the stranger thrust the flowing blossom into its face.

"The cow shrank back, Cunora! 'Twas deadly afraid of that beautiful flower!"

"That is odd," admitted Cunora. She was getting interested.

"Then he took me by the hand again, and we floated once more through the air. In a short time we arrived at the city of the masters. [Footnote: "Having no microscopes, the Sanusians could not know that the soldier bees were unsexed females; hence, "masters."] Before I knew it, he had me standing before the door of one of their palaces. I hung back, afraid lest we be discovered and punished; but he smiled again and spoke so reassuringly that I fled not, but watched until the end.

"With his finger he tapped lightly on the front of the palace. None of the masters heard him at first; so he tapped harder. Presently one of them appeared, and flew at once before our faces. Had it not been for the stranger's firm grasp I should have fled.

"The master saw that the stranger was the offender, and buzzed angrily. Another moment, and the master would surely have returned to the palace to inform the others; and then the stranger would have been punished with the Head Out punishment. But instead the angel very deliberately moved the blooming stick near unto the master; and behold, it was helpless! Down it fell to the ground, dazed; I could have picked it up, or killed it, without the slightest danger!

"Another master came out, and another, and another; and for each and all the flowing blossom was too much! None would come near it wittingly; and such as the angel approached with it were stricken almost to death.

"When they were all made helpless the angel bade me hold my hand near the bloom; and I was vastly surprised to feel a great warmth. 'Twas like the heat of a stone which has stood all day in the sun, only much greater. Once my finger touched the bloom, and it gave me a sharp pain."

Cunora was studying her friend very closely. "Ye could not have devised this tale, Rolla. 'Tis too unlikely. Is there more of it?"

"A little. The angel once more took me by the hand, and shortly set me down again in this hut. Then he said something which seemed to mean, 'With this magic bloom thou shalt be freed from the masters. They fear it; but ye, and all like ye, do not. Be ye ready to find the blossom when I bid thee.' With that he disappeared, and I awoke.

"Tell me; do I look mad, to thine eyes?" Rolla was beginning to feel a little anxious herself.

Cunora got up and led Rolla to the entrance. The glow of "the Silvery Way" was all the help that the girl's catlike eyesight needed; she seemed reassured.

"Ye look very strange and excited, Rolla, but not mad. Tell me again what thou didst see and hear, that I may compare it with what ye have already told."

Rolla began again; and meanwhile, on the earth, the doctor's companions telepathically congratulated him on his success. He had put the great idea into a fertile mind.

Presently they began to look for other minds. It seemed wise to get the notion into as many Sanusian heads as possible. For some hours this search proceeded; but in the end, after getting in touch with some forty or fifty individuals in as many different parts of the planet, they concluded that they had first hit upon the most advanced specimens that Sanus afforded; the only ones, in fact, whose intellect were strong enough to appreciate the value of what they were told. The investigators were obliged to work with Rolla, Dulnop, and Corrus only; upon these three depended the success of their unprecedented scheme.

Rolla continued to keep watch upon Supreme; and toward morning—that is, morning in that particular part of Sanus—the architect was rewarded by catching the bee in a still drowsy condition. Using the same method Kinney had chosen, Billie succeeded in giving the soldier bee a very vivid idea of fire. And judging by the very human way in which the half-asleep insect tossed about, thrashing her wings and legs and making incoherent sounds, Billie succeeded admirably. The other bees in the hive came crowding around, and Supreme had some difficulty in maintaining her dignity and authority. In the end she confided in the subordinate next in command:
