"We have no rivers," was the calm reply. "Rivers are entirely too wasteful of water. All our drainage is carried off through underground ca.n.a.ls."
"You haven"t done away with your oceans, too, have you?" the geologist asked, rather sarcastically. But he was scarcely prepared for the reply he got.
"No; we couldn"t get along without them, I am afraid. However, we did the best we could in their case." And without signaling to Estra she dove the machine towards the ground. Smith looked for the telephone wires to snap, but Estra seemed to know, and instantly followed Myrin"s lead. The doctor noticed, and wondered all the more.
And then came another surprise. As the machines neared the surface, a familiar odor floated in through the open windows of the air-craft; and the four found themselves looking at each other for signs of irrationality. A moment, and they saw that they were not mistaken.
For, although that kaleidoscopic expanse of buildings showed not the slightest break, yet they were now located on the sea. The houses were packed as closely together as anywhere; apparently all were floating, yet not ten square yards of open sea could be seen in any one spot.
Van Emmon almost forgot his resentment in his growing wonder. "That gets me, Myrin! Those houses seem to be merely floating, yet I see no motion whatever! Why are there no waves?"
The doctor snorted. "Shame on you, Van! Don"t let our friends think that you"re an absolute ignoramus." He added: "Venus has no moon, and no wind, at least under the roof. Therefore, no waves."
Smith put in: "That being the case, there is no chance to start a wave- motor industry here. Neither," as he thought further, "neither for water-power. Having no rain in your mountains, Estra, where do you get your power?"
But it was Myrin who answered. "I suppose you are all familiar with radium? It is nothing more or less than condensed sunlight, which in turn is simply electromagnetic waves; although it may take your scientists a good many centuries to reach that conclusion.
"Well, every particle of the material which composes this planet, contains radioactivity of some sort; and we long ago discovered a way to release it and use it. One pound of solid granite yields enough energy to--well, a great deal of power."
They had now been flying for two hours, and still no end to that thickly-housed, ever different appearance of the ground. Also, although they saw a great many birds, they noted no animals. Finally, Billie could hold in no longer.
"Are we to understand," she demanded of Estra, "that the whole of this planet is as densely populated as we see it?"
"Just that," replied the Venusian. "Why not? The roof makes our climate uniform from pole to pole, while our buildings are such that, whether on land or on sea, they are equally livable."
"But--Estra!" expostulated the girl. "Venus is nearly as big as the earth. And it looks to be as thickly populated as--as Rhode Island! Why, you must have a colossal population; let me see." And she scribbled away in her memorandum book.
But both Smith and the doctor had already worked it out. They looked up, blinking dazedly.
"Over three hundred billion," murmured the doctor, as though dizzy.
The Venusian checked Smith"s correction with, "You dropped one cipher, doctor. There are three and a half trillion of us!"
"Good lord!" whispered Van Emmon, all his antagonism gone for the moment. And again the explorers were silent for a long time.
By and by, however--"We have just seen what it meant, there on Mercury,"
said the doctor, in a low voice, "for the principle of "the survival of the fit" to be carried to its logical end; for who is to decide what is fitness, save the fittest? One man, apparently, outlived every one else on the planet, and then he also died.
"But here you have gone the limit in the other direction. Of course, we might have known that you long ago abolished poverty, unearned wealth, pestilence, drunkenness and the other causes of premature death; but as for three and a half trillion!"
"Nevertheless," remarked Myrin, "every last one of us, once born, lives to die of old age; and in most cases this means several hundred of your years."
Smith involuntarily rubbed his eyes; and they all laughed, a nervous sort of a laugh which left the visitors still in doubt as to their senses, and their guides" sanity. Van Emmon"s suspicions came back with a rush, and he burst out:
"Say--you"ll excuse me, but I can"t swallow this! Here you"ve shown us houses as thick as leaves; not a sign of a farm, much less an orchard!
No vegetation at all, except for a few flowers!
"Three and a half trillion! All right; let it go at that!" Out came his chin, and he brought one fist down upon the other as though he were cracking rocks with a hammer, and with every blow he uttered a word:
"How--do--you--feed--them--all?"

LOAVES AND FISHES
Without a word Myrin drove her machine toward the ground, and, as before, Estra followed despite the lack of any visible signal. Within a minute the two machines had come to rest, softly and without disturbance, on the roof of a handsome building, much like an apartment house. There was the usual transparent elevator, and a minute later the four were being introduced to the occupants of a typical Venusian house.
These two people, apparently man and wife, did not need to be told why the explorers had been brought there. They led the way from the dimly lighted hallway in which the elevator had stopped, into a group of brightly decorated rooms. Here the four were given seats in the usual saddellike chairs, and then Myrin answered Van Emmon"s question:
"I knew that this point would arise soon, and you will pardon me if I handle it in a prearranged fashion. I will admit that it is not an easy question Mr. Van Emmon has put; not because the answer is at all complicated but, on the contrary, extremely simple."
The four were listening unanimously. Despite himself, Van Emmon was highly impressed by the Venusian woman"s serious manner. Perhaps it was because, in her earnestness, she was not quite so affable as before. She went on:
"From where you are sitting, you can see all the rooms in this house.
You will look in vain for anything even remotely resembling a kitchen.
There is not even a dining-room.
"And yet you must not jump to the conclusion that we all use restaurants. We have no such thing as a public eating place. Or rather,"
and here she spoke very carefully, "rather, every place is an eating place."
The doctor looked Myrin over as though she were a patient with a new kind of disease. "You do not mean that literally, of course," said he kindly.
But she nodded gravely. "You must not misunderstand. Remember, even on your own planet, the distribution of food is becoming more and more extensive, until you can now buy something to eat at every crossroads.
We have merely carried the idea to its logical end, so that all Venusians can obtain food at any time, and at any spot."
She turned in her chair--all the chairs on Venus were pivoted, Estra said--and touched a b.u.t.ton in the wall at her hand. A panel slid noiselessly aside, and revealed a tiny buffet. At least, Billie labeled it a buffet, for want of a more accurate term.
For it consisted of a silver bibb, something like the nozzle of a soda- water fountain above which was a board containing a large number of tiny, numbered push b.u.t.tons. Below the bibb was a s.p.a.ce in which a cup might be set, and projecting from a tube at one side was a solid block of telescoping, transparent cups.
"This," said Myrin, "is the Venusian Nutrition System. There is a station like this in every room on the planet." And she proceeded to take a cup from the tube, filling each from the silver faucet while she pressed a variety of the b.u.t.tons.
The four watched in silence, and eagerly took what was given to them. It comprised liquids entirely; liquids of every degree of fluidity, from some as thin as water to others as thick as gruel. They varied even more as to color, ranging from actual transparency to a deep chocolate.
"Now, I warn you not to be shocked," said Myrin, "although I fully expect that you will be. The fact is that we have no other kind of food than what you see; there are thousands upon thousands of different kinds and flavors, but they are all fluids. We have nothing whatever in solid form.
"You see," she explained, "we have no teeth."
All they could do was to stare at her as, with a return of her smile, she made a sudden gesture across the front of her mouth. Next instant a set of false teeth lay in her hand!
Estra spoke up. "We are both obliged to wear them in order that we might use your language." He removed his own, to show a mouth as free of teeth as a newborn baby"s. Both Venusians replaced their sets, and smiled afresh at the explorers" astonishment.
"Teeth will soon be a thing of the past with you on the Earth, too,"
commented Myrin. "Dr. Kinney will surely testify to that. Your use of soft, cooked foods, instead of the coa.r.s.e, hard articles provided by nature, is bound to have this effect in time. With us, it resulted in having teeth reduced to the standing of your appendix; and, like you, we resort to an operation rather than take chances on trouble. I may mention that the appendix is totally absent from all Venusians, while we are beginning to lose all traces of either the first or second molars; just as you are beginning to lose your wisdom teeth.
"However, suppose you try our diet while I explain."
