e 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

"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."

Papa Wolf seized both of Ernest's hand. "No! Really! Ernest, you really
will go on with the professorship! Then I am satisfied. But we must not
let this work be in vain. This child of your mind, Ernest, it must be
recorded. It will help you in your professorship, eh?"

Ernest nodded. "It's really a great thing, father. Roger has a wonderful
mind."

"He's got a good mind, yes, but I'm asking you where would he have been
all these years without my boy? O Ernie! Ernie! You've taken ten years
off me! Now, you let me think. I'll sit and watch this engine of yours.
You go along about your work, Ernie." And Ernest, a tired look in his
eyes, went along as he was bidden.

It was dinner time before the tour of inspection was done. Mamma Wolf
spent the morning, after a nap, helping the girls to prepare a huge
