You can draw a good likeness of Tulla's face with the most familiar punctuation marks. The way she glided through the water, she might have had webs between her toes. Always, even on the barge, despite seaweed, gulls, and the sour smell of the rust, she stank of carpenter's glue, because her father worked with glue in her uncle's carpenter's shop. She was all skin, bones, and curiosity. Calmly, her chin in the cup of her hand, Tulla would look on when Winter or Esch, unable to contain himself, produced his modest offering. Hunching over so that the bones of her spine stuck out, she would gaze at Winter, who was always slow in getting there, and mutter: "Man, that's taking a long time!"

But when, finally, the stuff came and splashed on the rust, she would begin to fidget and squirm, she would throw herself down on her belly, make little rat's eyes and look and look, trying to discover heaven-knows-what, turn over, sit up, rise to her knees and her feet, stand slightly knock-kneed over the mess, and begin to stir it with a supple big toe, until it foamed rust-red: "Boy! That's the berries! Now you do it, Atze."

Tulla never wearied of this little game – yes, game, the whole thing was all perfectly innocent. "Aw, you do it," she would plead in that whining voice of hers. "Who hasn't done it yet? It's your turn."

She always found some good-natured fool who would get to work even if he wasn't at all in the mood, just to give her something to goggle at. The only one who wouldn't give until Tulla found the right words of encouragement – and that is why I am narrating these heroic deeds – was the great swimmer and diver Joachim Mahlke. While all the rest of us were engaging in this time-honored, nay Biblical, pursuit, either one at a time or – as the manual puts it – with others, Mahlke kept his trunks on and gazed fixedly in the direction of Hela. We felt certain that at home, in his room between snowy owl and Sistine Madonna, he indulged in the same sport

He had just come up, shivering as usual, and he had nothing to show. Schilling had just been working for Tulla. A coaster was entering the harbor under its own power. "Do it again," Tulla begged, for Schilling was the most prolific of all. Not a single ship in the roadstead. "Not after swimming. I'll do it again tomorrow," Schilling consoled her. Tulla turned on her heel and stood with outspread toes facing Mahlke, who as usual was shivering in the shadow of the pilothouse and hadn't sat down yet. A high-seas tug with a forward gun was putting out to sea.

"Won't you? Aw, do it just once. Or can't you? Don't you want to? Or aren't you allowed to?"

Mahlke stepped half out of the shadow and slapped Tulla's compressed little face left right with his palm and the back of his hand. His mouse went wild. So did the screwdriver. Tulla, of course, didn't shed one single tear, but gave a bleating laugh with her mouth closed; shaking with laughter, she arched her india-rubber frame effortlessly into a bridge, and peered through her spindly legs at Mahlke until he – he was back in the shade again and the tug was veering off to northwestward – said: "OK. Just so you'll shut your yap."

Tulla came out of her contortion and squatted down normally with her legs folded under her, as Mahlke stripped his trunks down to his knees. The children at the Punch-and-Judy show gaped in amazement: a few deft movements emanating from his right wrist, and his pecker loomed so large that the tip emerged from the shadow of the pilothouse and the sun fell on it. Only when we had all formed a semicircle did Mahlke's jumping Jim return to the shadow.

"Won't you let me just for a second?" Tulla's mouth hung open. Mahlke nodded and dropped his right hand, though without uncurving his fingers. Tulla's hands, scratched and bruised as they always were, approached the monster, which expanded under her questioning fingertips; the veins stood out and the glans protruded.

"Measure it!" cried Jürgen Kupka. Tulla spread the fingers of her left hand. One full span and another almost. Somebody and then somebody else whispered: "At least twelve inches!" That was an exaggeration of course. Schilling, who otherwise had the longest, had to take his out, make it stand up, and hold it beside Mahlke's: Mahlke's was first of all a size thicker, second a matchbox longer, and third looked much more grownup, dangerous, and worthy to be worshiped.

He had shown us again, and then a second time he showed us by producing not one but two mighty streams in quick succession. With his knees not quite together, Mahlke stood by the twisted rail beside the pilothouse, staring out in the direction of the harbor buoy, a little to the rear of the low-lying smoke of the vanishing high-seas tug; a torpedo boat of the Gull class was just emerging from the harbor, but he didn't let it distract him. Thus he stood, showing his profile, from the toes extending just over the edge to the watershed in the middle of his hair: strangely enough, the length of his sexual part made up for the otherwise shocking protuberance of his Adam's apple, lending his body an odd, but in its way perfect, harmony.

No sooner had Mahlke finished squirting the first load over the rail than he started in all over again. Winter timed him with his waterproof wrist watch; Mahlke's performance continued for approximately as many seconds as it took the torpedo boat to pass from the tip of the breakwater to the buoy; then, while the torpedo boat was rounding the buoy, he unloaded the same amount again; the foaming bubbles lurched in the smooth, only occasionally rippling swell, and we laughed for joy as the gulls swooped down, screaming for more.

Joachim Mahlke was never obliged to repeat or better this performance, for none of us ever touched his record, certainly not when exhausted from swimming and diving; sportsmen in everything we did, we respected the rules.

For a while Tulla Pokriefke, for whom his prowess must have had the most direct appeal, courted him in her way; she would always be sitting by the pilothouse, staring at Mahlke's swimming trunks. A few times she pleaded with him, but he always refused, though good-naturedly.

"Do you have to confess these things?"

Mahlke nodded, and played with his dangling screwdriver to divert her gaze.

"Will you take me down sometime? By myself I'm scared. I bet there's still a stiff down there."

For educational purposes, no doubt, Mahlke took Tulla down into the fo'c'sle. He kept her under much too long. When they came up, she had turned a grayish yellow and sagged in his arms. We had to stand her light, curveless body on its head.

After that Tulla Pokriefke didn't join us very often and, though she was more regular than other girls of her age, she got increasingly on our nerves with her drivel about the dead sailor in the barge. She was always going on about him. "The one that brings him up," she promised, "can you-know-what."

It is perfectly possible that without admitting it to ourselves we all searched, Mahlke in the engine room, the rest of us in the fo'c'sle, for a half-decomposed Polish sailor; not because we really wanted to lay this unfinished little number, but just so.

Yet even Mahlke found nothing except for a few half-rotted pieces of clothing, from which fishes darted until the gulls saw that something was stirring and began to say grace.

No, he didn't set much store by Tulla, though they say there was something between them later. He didn't go for girls, not even for Schilling's sister. And all my cousins from Berlin got out of him was a fishy stare. If he had any tender feelings at all, it was for boys; by which I don't mean to suggest that Mahlke was queer; in those years spent between the beach and the sunken barge, we none of us knew exactly whether we were male or female. Though later there may have been rumors and tangible evidence to the contrary, the fact is that the only woman Mahlke cared about was the Catholic Virgin Mary. It was for her sake alone that he dragged everything that can be worn and displayed on the human neck to St. Mary's Chapel. Whatever he did, from diving to his subsequent military accomplishments, was done for her or else – yes, I know, I'm contradicting myself again – to distract attention from his Adam's apple. And perhaps, in addition to Virgin and mouse, there was yet a third motive: Our school, that musty edifice that defied ventilation, and particularly the auditorium, meant a great deal to Joachim Mahlke; it was the school that drove you, later on, to your supreme effort.
