He felt almost faint and instinctively he sat down. Bauer had gone over to his own desk and stood leaning against it.
"I ought not to come in here and annoy you at this time," he said in his slow, almost stammering manner, "but I--you see, somehow I felt so lonely, so afraid, when I got off the train to-night, that I could not help the desire to see you, and they told me you must be in the shop. Heine says in the Lorelei, you know, 'Ich weiss nicht was soll es bedeuten, das Ich so traurig bin?' But I do know why I am so sad. It is disgrace which has befallen me, such deep disgrace to my home, my father------"
He stopped and looked at Walter timidly as if not quite sure how his confidence might be received. Walter sat with his head bowed, and smitten into silence. He did not know what to say, but Bauer probably took his silence for quiet sympathy, being of that nature himself and mistaking Walter's attitude for earnest attention.
"My father--you will understand what it means--has deserted my mother, and she has run away, the home destroyed is to be, and the disgrace--Oh, it is greater, more than I can endure, I said as I was obliged to come back for my things. It is more than I can bear alone, and you are so strong, so principled."
Walter cowered in his chair, appalled at the thing that was happening to him. Here was a soul in desperate need who had come to fling itself on him for companionship and courage, and he with his own soul stained with deception for the love of fame and money! He would have cried out; he wanted to, but Bauer went on, now he had broken over his natural reserve. He eagerly awaited Walter's sympathy, and his spirit hungered for light in his darkness.
"Yes, you see, I don't know anyone here, and your action about the story telling in your room--I heard of that--I counted it a brave thing to do. And, oh, I am so hungry for a friend! I need one; do you think you could be friend to me, do you, Douglas? Friend to a disgraced family? It is asking a great deal, but I feel the dark, the dark--it is so heavy for me------"
Bauer, looking at Walter in his almost animal-like appeal, saw at last that there was something he did not understand in Walter's attitude. Walter's mind was not confused by the strange situation, it was clear and vibrating with feeling. But it was a long time before he could speak. How could he tell Bauer the truth now? Why not let him remain in ignorance of the purpose to steal his ideas? Nothing had been done so far to really wrong him. The lamp was destroyed. Walter would not make another, and the basis of a possible friendship, such as Bauer needed, could be established without any explanation or foolish confession.
But somehow Walter could not rest with that suggestion. He felt that if Bauer had his friendship it must rest on truth and a frank outspoken revelation of the character of the soul he was appealing to for help.
It was very still in the big shop when Walter finally looked up and said to Bauer:
"I am not worthy of your friendship. I am not what you think I am."
"Not worthy? Not------" Bauer looked at him in amazement.
"No, not worthy. Look!" Walter spoke fast now as if afraid he might fail in courage. "Open your locker! Here! here is the key! You left it with me."
He thrust the key at Bauer, and Bauer turned around, and under the pressure of Walter's look and voice opened his locker and stood in front of it holding on to the door.
"There! That paper! Your plan, your drawing of the lamp! Open it. Let me show------"
Bauer obeyed mechanically. Walter got up and stood by Bauer's table. Bauer slowly unfolded the paper. His look showed he had almost forgotten it.
"There! See! You were on the right track! The soft metal teeth coupled to the electrode! Don't you see?" Bauer's face began to glow for the first time that evening, for he, too, like Walter, had the inventor's sensitive hunger. "You left the paper here the night you were called home. I saw it and copied it before I put it back. I made the model and it works. That is it there," and Walter pointed to the stuff on the table and in the refuse box. "Do you understand? I stole your plans. I was going to get out the lamp without telling you if you had not come back. And I am the person you want for a friend. Am I worthy? Do you understand now?"
A dull red spot began to creep up into the German student's face. He was still holding the locker door with one hand. His eye travelled from the diagram to Walter and then back again. Walter stood very erect, his head thrown back almost defiantly now that he had made his confession, and he was absolutely in the dark as to the effect of it on Bauer. He would and could not blame him for being angry. And he was angry for a moment. But only a moment. Then his great brown eyes softened and he said in a quiet, gentle way that moved Walter more than any burst of passion could have done:
"I am not a judge for you. While on the way home I suddenly thought out the secret of the metal teeth. See! I have it here." He took out of his pocket a paper and opening it spread it out on Walter's desk. Walter saw in a second's glance that Bauer had discovered the working basis for the successful light. "And I was going to work on the plan when I came back. But all my trouble drove it away. I lost my ambition. And I understand what you did. I might have done the same. But still, Douglas, do you know, I don't care. I--I am hungry for a friend just like you. What you have said does not change anything. What difference does that make? That is not trouble, not for me."
Walter looked at him a moment and then in the reaction which was really the taking off of the strain of weeks, he put his head between his hands and sobbed. Bauer did not venture to say anything. When Walter could control himself he reached out his hand. Bauer took it, and in that grasp the two young men understood each other for life. I think each gave as much as he took. The sacred compact they sealed in the big empty shop that night was made with few words, but it was never disturbed nor broken in after years. And each one of them realised something of the depth and joy of real friendship. Do you? Does anybody? Our human friendships, when they are real and permanent, are the finest and richest possessions of our lives. Pity we treat them so lightly and measure them so tamely.
That same night Bauer in his simple manner told Walter something more of his home troubles, enough to give Walter a glimpse into the real sorrow of his heart. Walter in his turn told in part the story of his temptation and of his struggles and tortures to escape. To this Bauer listened with a faint smile and with perfect understanding.
In the days that followed, they agreed to construct the lamp between them and share in the profits from it. And when they began work on the mechanism each found that the other had discovered little improvements which were necessary to the best construction, finally producing a lamp far more perfect and practical than Walter's first attempt.
The day after that memorable scene with Bauer in the shop Walter wrote home a long and exuberant letter, a part of which we may read.
"Mother, I can't begin to tell you what a relief I have experienced since I told Bauer all about it. I believe I had a little taste of hell for a while and I don't want to go through it again. Bauer and I are the best friends you ever saw. He is just the opposite of me. I'm impulsive and quick and get mad quick and all that. You know all about it, but he is slow and calm and talks only a little at a time. He is not what you would call handsome, but he has the most beautiful brown eyes I ever saw. If I was a girl I would think he was handsome because his eyes are. He has told me a good deal about his home life and I have told him something about ours, and he has asked some questions. And, oh yes, he is coming home with me for the holidays. At first he refused, but when I told him how much you wanted him to come and how lonesome it would be for him here he consented to come. I hope you will all like him. Helen will probably think he is odd and solemn, but I hope she will be kind and all of us can make him feel at home.
"We are working on the lamp together and it is almost finished. We are keeping
