"That's all I lack," said Walter. "If I could get your 'einege gewolite,' I would have my answer."
"Hope you will get it," said Bauer, pleasantly, as he closed up his locker and went out to meet another class period.
After he had gone, Walter worked on until he was the only person left in the workroom. He had the entire afternoon and evening, as it happened, and was so absorbed in his experiments that he was hardly aware of his being alone until he looked up and saw that the big room was empty, and that it was dusk. Without any thought of supper he turned on the light over his table and made some mathematical calculations. Then he ran out of paper and looked about over the litter of stuff in front of him for another piece, but not finding any, glanced naturally over to Bauer's table, which was next his own.
There was a folded bit of paper there, and Walter reached out for it, took it, and opened it up. It was covered on one side with some drawings and diagrams, and as Walter looked at them, not paying much attention at first, as he worked a high power formula over in his head, a little at a time it dawned on him as he continued to stare at Bauer's drawings, that without having realised it himself, perhaps, Bauer had actually suggested in his own drawing the key to the arc light Walter had been puzzling over for several months without success.
"Yes! yes!" Walter was saying, excitedly, to himself. "I see it! I see it! What a dummy I was. The electrodes can be fitted with teeth at equal distances. Let the tooth rest on the porcelain plate. It will gradually soften and melt under the heat of the arc. Thenthen. I see! I seethe electrode will, or it ought to, drop down of its own weight upon the next tooth. Then that will melt and the electrode will drop again. The two electrodes can be coupled together with a scissors coupling, so the teeth will have to be made in only one of them. I see the whole thing! Hurrah!" He said the last word out loud. The echo of it in the big, empty shop startled him. The glow of the discoverer, of the inventor, was on him and within him. Then he received a distinct reaction. That was Bauer's paper, not his! He had left it out of the locker when he went away! It was Bauer's discovery, not his, even if Bauer did not yet realise the real value and meaning of his diagram. He was on the road to the discovery.
Walter stared at the paper again and wished he had never seen it. For he was face to face with a real temptation, one of the hardest and most alluring his young manhood had ever confronted, and he was afraid, as he continued to stare at the diagram made by Felix Bauer.
CHAPTER IV
IT was ten o'clock at night when Walter finally went out of the shop and up to his room. He did not turn on the light at once, but went over by his table and sat down.
The temptation he still faced had assumed alluring shapes. In the first place, he was saying to himself, "Bauer's drawings differ only a trifle from my own and I had practically gone as far as he, only one or two points were suggested to me by his diagram of the electrodes resting at an angle on the porcelain plate. The cutting of the teeth in the soft metal was also suggested by him. But I had thought out other points that were essential."
Then, again, Walter kept going over the great advantage it would be to him if this discovery were made by him first. He knew that the commercial value of any real improvement in city lighting was very large. There was money for him in this discovery. And Walter was growing more and more restless over his stewardship and the burdens it involved. He hated the drudgery and the time it took, and of late he began to feel quite certain that the same attitude displayed in other schools was creeping into Burrton, an attitude of contempt for the working student, nothing very pronounced, but enough to make him feel disagreeable and annoyed, for he was a finicky youth, sensitive to a great degree and with the taste of an aristocrat at heart.
"I don't see that I do Bauer any harm if I go ahead and make a model. I'll do that anyhow," he said out loud at last, as he got up and turned on his light. And then he saw under the edge of his door a note which had been slipped in there.
He went over, picked it up, opened it, and found it was a note from
Bauer.
"My Dear Douglas:Within an hour after leaving the shop to-night I had a telegram calling me home. I do not know how soon I shall be able to return to Burrton, if at all. Will you kindly see if I left any of my apparatus or papers on my table and return them to my locker? I enclose the key with this note. Thank you. "FELIX BAUER."
So Bauer was going to be away indefinitely. He might not come back at all. He had not given any reason for the call to come home, but Walter remembered one remark the German student had made one day which led him to believe that Bauer's home life was unhappy and the relations between his father and mother were unpleasant. Suppose he never came back. Suppose he never finished his investigation of the lamp? Supposethere was a number of possibilities to suppose. Why, then the field would be open to him and he could go ahead with a clear conscience. But could he? In spite of all sophistry and special pleading with himself Walter knew he had caught the idea of the electrodes from Bauer's drawing, which suggested the secret. How did he know but that Bauer had discovered it as indicated in his own diagram and was making that preliminary to the finished lamp?
There was one honest and plain way out for Walter. He could write to Bauer and frankly tell him that he had seen his drawings and had received from them a hint for the discovery and ask him if he were willing to share with him, Walter, in the result if the lamp proved worth while financially. But here was Walter's weak point. He was proud of his technical knowledge. Already it was conceded by all the students in the electrical engineering department that Douglas of Milton was the star. The instructors had given him special notice. He had already made one or two very valuable and original contributions to the problems that faced the shop every day. But nothing he had so far done would begin to compare with this new arc light. The thought of sharing his discovery with any one else touched his pride in its most sensitive and personal spot.
He threshed it all over back and forth and when he finally went to bed he was still undecided as to his course. The fact is, he could not escape all the time the standard he had been trained in at home. If Paul and Esther had done nothing else for their children they had certainly done this; they had implanted in their minds a deep and strong feeling that one of the things to be most desired in life is honesty; clean, frank, wholesome honesty, free from cant and hypocrisy and double dealing. And Walter knew in his heart that what he was going to do was not honest to Bauer, even after he had juggled with his conscience and proved to himself that Bauer had no real rights in the matter. He knew perfectly well that the German student did have rights of prior discovery. No amount of argument or defense of his own discoveries could remove that fact.
Nevertheless, next day in the shop after he had put Bauer's belongings, including the paper with the drawings, into Bauer's locker, Walter found himself working with nervous haste over his model. It went together with wonderful exactness and in spite of his feeling that he was acting the part of a miserable cheat, he was, at least, during a part of the time, in a glow of enthusiasm. For the most part he worked at night, when he was least liable to watching from the other fellows. There were several reasons why he could do this, among them an unusual interest in the school at that time in evening functions which drew most of the shop workers out.
