Again there was full silence in the room. Then Dean Erskine cleared his throat. "Ernest, I want to thank you very much. I, too, am an American."
Papa Wolf blew his nose and walked slowly out of the house. There was no one in the room who had not been moved deeply by the something poignant in Ernest's face, even though his voice was so sedulously casual. Before any one else had opportunity to speak however, Papa Wolf was back.
"I don't believe a word about Werner," he said to Ernest. "But I am surprised, Ernest, after your upbringing that you should have deceived Roger as you did."
"But are you an American, Papa?" persisted Ernest.
"You numb-skull!" shouted his father. "I have been an American longer than you have hairs to your head. It's my land, even if I am sentimental about Germany."
Once more he marched out the door.
"Come, Dean, and see the Plant," said Roger. The Dean rose with alacrity and bumped into Papa Wolf, who came in again shaking his head.
"I don't see, Ernie, how you could have treated Roger so. Of course, I think he's crazy and all his works. But I've always loved him, though I was and am very mad at him for bringing you down here. I don't see how you could have done it."
"I thought I owed it to Germany and that it would help him. You forget my German superman upbringing."
"I'll look at the Plant, of course," said Papa Wolf, "just to see what you have wasted your life blood on. But not one cent of money, boys."
"I don't want your money, sir," exclaimed Roger, proudly.
"You don't eh! Then we're all satisfied," returned Ernest's father, following the Dean out of the door.
The last place inspected was the engine house. Ernest made a simple explanation of the machinery while the Dean went over the engine almost as lovingly and keenly as Roger would have. Then Roger led the Dean back to the porch for a talk.
"So this is the result of all your years of work, eh, Ernie?" said Papa Wolf. "Do you mean to say that you made that machine out of your own head?"
"I only helped Roger," replied Ernest, "but it means a lot to me. Father, this solar work of ours will be recorded in history as the beginning of a new harnessing of energy."
The older man looked at his son with interest. "You should have taken the trouble to explain all this to me, years ago, my son."
"I know it," replied Ernest. "Well, anyhow, I've done my bit down here. When you go back I'll go back with you. I'm a teacher, not a pioneer."
