"I don't? Who will prevent it?"

"I will."

Van Shaw turned a little toward Walter. Douglas was smaller, shorter, and of lighter build in every way than himself. But he was in the real point of vantage, in his own room. The other students did not seem disposed to take any sides in the matter. But one of them said: "Oh, cut it out, Van, if Douglas doesn't like it. A fellow has a right to say what he wants in his own room. It's only a matter of taste anyhow."

Van Shaw looked at Walter savagely. Then he sauntered across the room.

"Come out in the hall, fellows, and I'll finish there. This air is too pious for my health."

Some of the boys laughed, and three or four fellows followed Van Shaw out. The rest stayed. When the door shut on Van Shaw, one of the older students, who had been silent throughout, walked up to Walter and shook hands with him. Then the rest of the group followed. Not a word was said by anyone. These youths, some of them already hardened by dissipation, had at least the native good sense not to mar the occasion by any silly attempt at words. They simply shook Walter's hand and went out. And when the last one was gone, Walter turned the key in his door and went into his bedroom adjoining, and flung himself down on the bed and cried.

I don't know that he could have given any real reason for his emotion. But he was somewhat unstrung by the event. And a number of tumultuous feelings were stirring deeply in him. He turned hot and cold at the thought of his own possible cowardice. And then he felt a reaction of shame in the thought that after this, Van Shaw and all his set would cut him dead. He was ashamed to feel, even after all he had done, that he still shrank from the possibility of social scorn, even from a set of men who had no more moral standing than Van Shaw had.

But, on the whole, having stood by his rights as he had, and having the pleasant consciousness of being true to his own principles, he was disposed to feel a glow of commendation, and later in the evening as Helen's splendid picture looked at him almost as if she was present, Walter said to himself: "I'm glad I spoke out. I'm glad."

And then, because he had been brought up from a small boy to confide in his mother, he found great relief for his feelings that same night in writing to her. He mentioned no names, simply said that curiously soon after his mother had written as she did about guarding his own room from evil talk he had had an opportunity to do it. He did not dwell upon the matter at all, and did not take any special credit to himself for his action, but simply reminded his mother again of the difference in standards and conduct. He expressed gratitude that some of the fellows had at least silently stood by him. And he ended his letter by saying that he was almost on the edge of discovery of the arc light, although it still eluded him.

For the next two weeks Walter was completely absorbed in his studies. Every spare hour he could get he pored and worked over his original problem. There were points about it which perplexed and exasperated him. Felix Bauer was as hard at work on the same problem as himself, and said one evening with a good-natured laugh that he believed he had mastered it. "All I lack is that one thing necessary what we call the 'Beduerfniss' the 'einege gewolite,'" said Bauer, as he took off his shop cap and thoughtfully ran a lead pencil back and forth through the short curly hair over his ear.
