"Well, when your father read this, he simply choked. In fact we all choked, and Helen who happened to get hold of it somehow, just screamed. Poor Louis was mad at every one of us and especially at Miss Barrows when he heard she had taken his account to his father. At first your father thought Louis was trying to be funny at the expense of the English department in the high school. But he wasn't. He was in dead earnest, and doing his best. I tell your father that it isn't fair to ridicule Louis. Ridicule is a dangerous form of criticism and Louis is very sensitive. I don't blame him for saying that the teacher ought not to make fun of him when he is trying to get his lessons. He fairly hates some of his teachers because they use sarcastic or ironical remarks about him in the presence of the whole school. It seems strange to me that any teacher will do that, especially in the case of a boy like Louis. They defend themselves by saying it is the only way to wake up the students or shame them into doing good work. But I believe they are wrong in their methods with boys like Louis and I am going to talk with them about it for his sake. "We will welcome Bauer with you at the holidays. He will feel at home with us if your mother has anything to do about it. We all anticipate his coming. If you are a little homesick to see us we are all more than a little eager to see you. I pray the good God to keep you pure and true. Lovingly, "MOTHER." Two weeks after this and two weeks before the Christmas holidays, Walter and Bauer had completed their lamp and given it a test. It was more perfect by far than Walter's model. It worked with a practical certainty that left no doubt in their minds that unless some unforeseen factor came in to change conditions they had a workable, economic mechanism which was automatic and durable. Within a day or two they decided to let Anderson into the secret and Walter asked him to come into the shop at night to see the result of some special original work. This was a common request and the foreman simply made his engagement at the hour assigned, and when the hour came he went in and Watched Walter and Bauer bring out the lamp and make the necessary connections. Anderson had respect for Walter's ability, recognising in him the brightest mind for electricity that Burrton had ever seen in a student. He stood by silently at first while Walter in considerable excitement and some evident pride did the explaining. But when the light started in the arc and the brilliant glow of it began to fling out its dazzling shafts through the shop the professor started forward, a look of astonishment came over his face and he asked Walter a question, so unexpected, that Walter turned pale and looked first at Anderson and then at Bauer in blind wonder and a great sinking of heart. CHAPTER VI "DIDN'T you know that this lamp has already been made and patent applied for by Gambrich of New York?" "No! When?"
