young polyp of the opposite gender, whom you would invite to share your homesite. Or, if not, you should take all the more pains to make that site as attractive as possible, in order that such a one may decide to grace it with—”
“Uh-huh,” said Junior understandingly. “That’s what the fellows mean when they say any of ‘em’ll fall for a few high-class rocks.”
Pater marshaled his thoughts again. “Well, quite apart from such material considerations as selecting the right rocks, there are certain ... ah ... matters we do not ordinarily discuss.”
Mater blushed a more pronounced lavender. The three maiden aunts, rooted to their boulder within easy earshot of Pater’s carrying voice, put up a respectable pretense of searching one another for nonexistent water-fleas.
“No doubt,” said Pater, “in the course of your harum-scarum adventurings as a normal polyp among polyps, you’ve noticed the ways in which the lower orders reproduce themselves; the activities of the fishes, the crustacea, the marine worms will not have escaped your attention.”
“Uh-huh,” said Junior, treading water.
“You will have observed that among these there takes place a good deal of ... ah ... maneuvering for position. But among intelligent, firmly rooted beings like ourselves, matters are, of course, on a less crude and direct plane. What among lesser creatures is a question of tactics belongs, for us, to the realm of strategy.” Pater’s tone grew confiding. “Now, Junior, once you’re settled you’ll realize the importance of being easy in your mind about your offspring’s parentage. Remember, a niche in brine saves trying. Nothing like choosing your location well in the first place. Study the currents around your prospective site—particularly their direction and force at such crucial times as flood-tide. Try to make sure you and your future mate won’t be too close down-current from anybody else’s site, since in a case like that accidents can happen. You understand, Junior?”
“Uh-huh,” acknowledged Junior. “That’s what the fellows mean when they say don’t let anybody get the drop on you.”
“Well!” said Pater in flat disapproval.
“But it all seems sort of silly,” said Junior stubbornly. “I’d rather just keep moving around, and not have to do all that figuring. And the ocean’s full of things I haven’t seen yet. I don’t want to grow down!”
Mater paled with shock. Pater gave his spawn a scalding, scandalized look. “You’ll learn! You can’t beat Biology,” he said thickly, creditably keeping his voice down. “Junior, you may go!”
Junior bobbled off, and Pater admonished Mater sternly, “We must have patience, my dear! All children pass through these larval stages....”
“Yes, dear,” sighed Mater.
At long last, Junior seemed to have resigned himself to making the best of it.
With considerable exertions, hampered by his increasing bottom-heaviness, he was fetching loads of stones, seaweed and other debris to a spot downslope, and there laboring over what promised to be a fairly ambitious cairn. Judging by what they could see of it, his homesite might even prove a credit to the colony (so went Pater’s thoughts) and attract a mate who would be a good catch (thus Mater mused).
Junior was still to be seen at times along the reef in company with his free-swimming friends among the other polyps, at some of whom his parents had always looked askance, fearing they were by no means well-bred. In fact, there was strong suspicion that some of them—waifs from the disreputable Shallows district in the hazardous reaches just below the tide-mark—had never been bred at all, but were products of budding, a practice frowned on in polite society.
However, Junior’s appearance and rate of locomotion made it clear he would soon be done with juvenile follies. As Pater repeated with satisfaction—you can’t beat Biology; as one becomes more and more bottle-shaped, the romantic illusions of youth must inevitably perish.
“I always knew there was sound stuff in the youngster,” declared Pater expansively.
“At least he won’t be able to go around with those ragamuffins much longer,” breathed Mater thankfully.
“What does the young fool think he’s doing, fiddling round with soapstone?” grumbled Pater, peering critically through the green to try to make out the details of Junior’s building. “Doesn’t he know it’s apt to slip its place in a year or two?”
“Look, dear,” hissed Mater acidly, “isn’t that the little polyp who was so rude once?... I wish she wouldn’t keep watching Junior like that. Our northwest neighbor heard positively that she’s the child of an only parent!”
“Never mind.” Pater turned to reassure her. “Once Junior is properly rooted, his self-respect will cause him to keep riffraff at a distance. It’s a matter of Psychology, my dear; the vertical position makes all the difference in one’s thinking.”
The great day arrived. Laboriously Junior put a few finishing touches to his construction—which, so far as could be seen from a distance, had turned out decent-looking enough, though it was rather questionably original in design: lower and flatter than was customary.
With one more look at his handiwork, Junior turned bottom-end-down and sank wearily onto the finished site. After a minute, he paddled experimentally, but flailing tentacles failed to lift him. He was already rooted, and growing more solidly so by the moment.
“Congratulations!” cried the neighbors. Pater and Mater bowed this way and that in acknowledgment. Mater waved a condescending tentacle to the three maiden aunts.
“I told you so!” said Pater triumphantly.
“Yes, dear....” said Mater meekly.
Suddenly there were outcries of alarm from the dwellers down-reef. A wave of dismay swept audibly through all the nearer part of the colony. Pater and Mater looked around, and froze.
Junior had begun paddling again, but this time in a most peculiar manner—with a rotary twist and sidewise scoop which looked awkward, but which he performed so deftly that he must have practiced it. Fixed upright as he was now on the platform he had built, he looked for all the world as if he were trying to swim sidewise.
“He’s gone mad!” squeaked Mater.
“I ...” gulped Pater, “I’m afraid not.”
At least, they saw, there was method in Junior’s actions. He went on paddling in the same fashion and now he, and his platform with him, were farther away than they had been, and growing more remote as they stared.
Parts of the homesite that was not a homesite revolved in some way incomprehensible to eyes that had never seen the like. And the whole affair trundled along, rocking at bumps in the sandy bottom, and squeaking painfully; nevertheless, it moved.
The polyps watching from the reef swam out and frolicked after Junior, watching his contrivance go and chattering eager questions, while their parents bawled at them to keep away from that.
The three maiden aunts shrieked faintly and swooned in one another’s tentacles. The colony was shaken as it had not been since the tidal wave.
“COME BACK!” thundered Pater. “You CAN’T do that!”
