"Dry up, Ern," said Roger.
"What sort of a thing is it, this desert machine?" asked Uncle Hugo.
"It's a method of utilizing solar heat for power," replied Roger.
"Ah, yes, the big umbrella-like things. I've seen them in the pictures."
"Not at all," corrected Roger crossly.
Ernest spoke suddenly, very firmly but without raising his gentle voice. "I'm sorry to go against your wishes, Papa, but I'm going, just the same."
His father's mouth opened in astonishment. There was silence for a moment, broken by a sob from Mamma Wolf. Then Papa Wolf roared: "So that's it! You are of age. But disobedience I will not countenance. If you go, never again can you live in my house."
"Oh, Karl!" cried Mamma Wolf.
Elsa sniffed audibly. "What a tempest over a little thing! Uncle Hugo, have some more beer?"
"I must be going," said Hugo, taking the beer nevertheless.
"So must I," exclaimed Roger, rising hastily. "Then it's settled, Ernest?"
Ernest leaned over to take another sandwich. "It's settled. Don't cry, Mütterchen. I'll bring you home a horned toad and you can make me a bed and serve my meals in the garage."
Roger took Mamma Wolf's hand and kissed her cheek. "Good night, dear," he whispered.
Mamma Wolf smiled bravely and clung to his fingers for a moment. "You have made me sad, Roger, but I can't help loving you!"
Roger kissed her again. "I'm not going to let you be sad long. I'll bring Ernie back to you safe and sound. Well, I'm off to bed! Good night, Elsa!" and he was gone with a bang of the front door.
The days to Christmas flew by with unbelievable speed. Papa Wolf washed his hands of the whole adventure, as Elsa continued to call it, and refused to allow any mention of it in his hearing. This was Ernest's first insurrection, and his father seemed to have no tool but silence with which to combat it. Christmas eve and Christmas day were celebrated with all the usual beautiful German customs. It seemed to Roger that he enjoyed them more each year, and this year, with the novel sense of achievement in his heart, the joy of the day was unalloyed.
Although Papa Wolf was obdurate about the adventure, his big heart could not permit him to allow him to let Austin spend Christmas day in a hotel. When he learned that Austin had a wife and child in Washington, nothing would do but that the Smithsonian man should share in a home Christmas. Papa Wolf provided another guest also, a stranger named Adolph Werner. He was a German banker, traveling across America on business, and the Wolf family was instructed to treat him with great deference. Stout and bespectacled, he proved a delightful guest and Dr. Austin displayed a gift for comic songs that brought the house down.
