That, in itself, was bad news.

One of the cries was clear. He could easily make out the basic distress call. It was the earliest Dolphin signal human scientists had understood.

But the other noise… at least three voices were involved in that one. It was a strange sound, very poignant and very wrong!

"It isss rescue fever," Brookida groaned. "Hikahi is beached and injured. She might have stopped this, but she is delirious and now adds to the problem!"

"Hikahi…"

"Like Creideiki, she is an adept of Keneenk… the study of logical discipline. She would have been able to force the others to ignore the cries of those washed ashore, to make them dive to safety for a t-time."

"Don't they realize there will be aftershocks?"

"Shockss hardly matter, Sharp-Eyes!" Brookida cried. "They may beach themselves without assist! You are Calafian. How can you not know this about usss? I thrash here to go and die answering that call!"

Toshio groaned. Of course he knew about rescue fever, in which panic and fear washed aside the veneer of civilization, leaving a cetacean with only one thought — to save his comrades, whatever the personal risk. Every few years the tragedy struck even the highly advanced fins of Calafia. Akki had told him, once, that sometimes the sea itself seemed to be calling for help. Some humans claimed to have felt it, too — particularly those who took dolphin RNA in the rites of the Dreamer Cult.

Once upon a time the Tursiops, or bottlenose dolphin, had been about the least likely cetacean to beach himself. But genetic engineering had upset the balance somewhere. As the genes of other species were spliced onto the basic Tursiops model, a few things had been thrown out of kilter. For three generations human geneticists had been working on the problem. But for now the fins swam along a knife edge, where irrationality was a perpetual danger.

Toshio bit his lip. "They have their harnesses," he said uncertainly.

"One can hope. But is it likely they'll use them properly when they are even now speaking P-primal?"

Toshio struck the sled with his balled fist. Already his hand was growing numb from the chill. "I'm going up," he announced.

"No! You must not! You must guard your safet-ty!"

Toshio ground his teeth. Always mothering me. Mothering or teasing. The fns treat me like a child, and I'm sick of it!

He set the throttle to one-quarter and pulled up on the bow planes. "I'm going to unlash you, Brookida. Can you swim okay?"

"Yesss. But-t…"

Toshio looked at his sonar. A fuzzy line was forming in the west.

"Can you swim!" he demanded.

"Yesss. I can swim well enough. But don't cut me loose near the rescue fever! Don't you risk the aftershocksss!"

"I see one coming now. They'll be several minutes apart and weakening with time. I'll fix it so we rise just after this one passes. Then you've got to get going back to the ship! Tell them what's happened and get help."

"That's what you should do, Toshio."

"Never mind that! Will you do as I ask? Or do I have to leave you lashed up!"

There was an almost unnoticeable pause, but Brookida's voice changed. "I shall do exactly as you say Toshio. I'll bring help."

Toshio checked his trim, then he slipped over the side, holding onto the rim stanchions with one hand. Brookida looked at him through the transparent shell of the airdome. The tough bubble membrane surrounded the dolphin's head. Toshio tore loose the lashings holding Brookida in place. "You're going to have to take a breather with you, you know."

Brookida sighed as Toshio pulled a lever by the airdome. A small hose descended, one end covering Brookida's blowhole. Like a snake, ten feet of hose wrapped around Brookida's torso. Breathers were uncomfortable, and hindered speech. But by wearing one Brookida would not have to come up for air. The breather would help the old metallurgist ignore the cries in the water — a constant, uncomfortable reminder of his membership in a technological culture.

Toshio left Brookida tied in place by a single lashing. He pulled himself back onto the upper surface just as the first aftershock rolled overhead.

The sled bucked, but he was prepared this time. They were deep, and the wave passed with surprising quickness.

"Okay, here goes." He pushed the throttle forward to max and blew ballast.

Soon the metal island appeared on his left. The screams of his comrades became distinctly louder over the sonar set. The distress call was now pre-eminent over the rescue fever response.

Toshio steered past the mound to the north. He wanted to give Brookida a big head start.

Just then, however, a sleek gray figure shot past Toshio, just overhead. He recognized it at once, and where it was headed.

He cut the last lashing. "Get moving, Brookida! If you come back anywhere near this island again I'll rip off your harness and bite your tail in half!"

He didn't bother looking back as Brookida dropped away and the sled turned sharply. He kicked in emergency power to try to catch up with Keepiru. The fastest swimmer in the Streak's crew was heading directly for the western beach. His cries were pure Primal Dolphin.

"Damn you, Keepiru. Stop!"

The sled sped quickly, just under the water's surface. The afternoon had aged, and there was a reddish tinge to the clouds, but Toshio could clearly see Keepiru leaping from wavelet to wavelet up ahead. He appeared indifferent to Toshio's calls as he neared the island where his comrades lay beached and delirious.

Toshio felt helpless. Another aftershock was due in three minutes. If it didn't beach the dolphin, Keepiru's own efforts probably would. Keepiru came from Atlast, a new and rather rustic colony world. It was doubtful he had learned the tools of mental discipline studied by Creideiki and Hikahi.

"Stop! If we time it right we can work as a team! We can avoid the aftershocks! Will you let me catch up?" he screamed. But it was no use. The fin had too much of a head start. The futile chase frustrated Toshio. How could he have lived and worked with dolphins all his life and known them so poorly? To think the Terragens Council had chosen him for this tour because of his experience with fins! Hah!

Toshio had always taken a lot of kidding from fins. They kidded all human children, while protecting them ferociously. But on signing aboard Streaker, Toshio had expected to be treated as an adult and officer. Sure, there'd be a little repartee, as he'd seen between man and fin back home, but mutual respect, as well. It hadn't worked out that way.

Keepiru had been the worst, starting right off with heavy sarcasm and never letting up.

So why am I trying to save him?

He remembered the fierce courage Keepiru had shown in saving him from the weed. There was no rescue fever then. The fin had been in full control over his harness.

So, he thinks of me as a child, Toshio realized bitterly. No wonder he doesn't hear me now.

Still, it offered a way. Toshio bit his lip, wishing vainly for an alternative. To save Keepiru's life he would have to humiliate himself utterly. It wasn't an easy thing to decide to do, his pride had taken such a beating.

With a savage curse, he pulled back on the throttle and set the bow planes to descend. He turned up the hydrophones to maximum, swallowed, then cried out in pidgin Trinary.

* Child drowning — child in danger! *

* Child drowning — child's distress *

* Human child — in need of savior *

* Human child — come do your best! *

He repeated the call over and over, whistling through lips dry with shame. The nursery rhyme was taught to all the children of Calafia. Any kid past the age of nine who used it usually pleaded for transfer to another island to escape the subsequent razzing. There were more dignified ways an adult called for help.
