After washing from his hands and face the dust and soil of work, Joe left the kitchen, and went to the little bedroom. A pair of large bright eyes looked up at him from the snowy bed; looked at him tenderly, gratefully, pleadingly. How his heart swelled in his bosom! With what a quicker motion came the heart-beats! Joe sat down, and now, for the first time, examining the thin free carefully under the lamp light, saw that it was an  attractive face, and full of a childish sweetness which suffering had not been able to obliterate.

“Your name is Maggie?” he said, as he sat down and took her soft little hand in his.
“Yes, sir.” Her voice struck a chord that quivered in a low strain of music.
“Have you been sick long?”
“Yes, sir.” What a sweet patience was in her tone!
“Has the doctor been to see you?”
“He used to come”
“But not lately?”
“No, sir.”

How did Maggie look at Joe when he entered her room?


Then, trying to hide my nervousness, I added, “How are you?”
“I’m fine. The question is: How are you?“
“What do you mean?” 1 asked “Something must be eating you,” he said—proud the way foreigners are when they’ve mastered a bit of American slang. “You should be able to qualify with your eyes closed.”
“Believe me, I know it,” I told him—and it felt good to say that to someone.

For the next few minutes we talked together. I didn’t tell Long what was “eating” me, but he seemed to understand my anger, and he took pains to reassure me. Although he’d been schooled in the Nazi youth movement, he didn’t believe in the Aryan-supremacy business any more than I did. We laughed over the fact that he really looked the part, though. An inch taller than I, he had a lean, muscular frame, clear blue eyes, blond hair and a strikingly handsome, chiseled face. Finally, seeing that I had calmed down somewhat, he pointed to the take-off board.

“Look,” he said. “Why don’t you draw a line a few inches in back of the board and aim at making your take-off from there? You’ll be sure not to foul, and you certainly ought to jump far enough to qualify. What does it matter if you’re not first in the trials? Tomorrow is what counts.”

Describe Luz Long.


Margot stood alone. She was a very frail girl who looked as if she had been lost in the rain for years and the rain had washed out the blue from her eyes and the red from her mouth and the yellow from her hair. She was an old photograph dusted from an album, whitened away, and if she spoke at all her voice would be a ghost. Now she stood, separate, staring at the rain and the loud wet world beyond the huge glass. “What’re you looking at ?” said William. Margot said nothing. “Speak when you’re spoken to.” He gave her a shove. But she did not move; rather she let herself be moved only by him and nothing else. They edged away from her, they would not look at her. She felt them go away. And this was because she would play no games with them in the echoing tunnels of the underground city. If they tagged her and ran, she stood blinking after them and did not follow. When the class sang songs about happiness and life and games her lips barely moved. Only when they sang about the sun and the summer did her lips move as she watched the drenched windows.
