"You spoil us all, Mamma!" he exclaimed. "Elsa, Uncle Hugo comes to-night and we will have a little music. You will give up choir practice, just for once."
Ernest glanced at his sister apprehensively. She flushed resentfully.
"But I must go, Papa!" she cried. "I take the salary the church pays me.
I must sing well."
"Laughing and flirting with the new ba.s.s is not practice," returned Papa. "You stay at home to-night, Elschen."
Elsa glanced at Ernest, who shrugged his shoulders. Then she gave a long look at her father with eyes that were black with anger.
"Papa, I"m going to choir practice," she insisted.
Her father brought his fist down on the table. "Am I or am I not master in my own house?" he shouted. "Elsa, what you have needed was a German upbringing. You will stay at home to-night and make music with Hugo and me."
"Papa," said Elsa slowly, "I am twenty-nine years old and I can"t endure this sort of thing much longer. Mother and I are just unpaid servants for--"
"Elsa! Bitte! Bitte sehr!" exclaimed Mother Wolf.
Elsa"s dark look went to her mother, then to Roger, who was still scowling. Her lips trembled. She shrugged her shoulders and rising began to clear the table.
The three men went into the library and lighted their pipes. Papa Wolf, having with much difficulty persuaded his meerschaum to draw, parted his coat-tails and settled himself on the piano stool. Then he threw his head back while he touched a few quiet chords. He had a beautiful, ma.s.sive head. Roger, ensconced in a deep Morris chair, thought, as he had thought many times before, that it was a head that should have belonged to an artist rather than to a dry goods merchant. The chords merged into a quiet melody. Ernest buried his head in the evening paper.
Roger let his pipe go out and his face settled into lines that added ten years to his age.
The subdued clatter of dishes from the kitchen finally ceased and Elsa came through the room. Her father stopped her as she pa.s.sed and put his arm about her waist.
"Sweetheart, don"t be cross with me," he said. "It"s just that Papa so loves to have his little girl with him."
Elsa put her hand on his gray head and looked down into his face but said nothing.
"Come now," he went on, "sing a little song of forgiveness with me."
Still with his arm about her he played with one hand and sang as he played:
"Du, du! liegst mir im Herzen!
Du, du! liegst mir im Sinn!
Du! du! machst mir viel Schmerzen Weiss nicht wie gut ich dir bin."
There was a sudden ring at the doorbell and with a little laugh that was half a sob, Elsa hurried to let Uncle Hugo in. He was tall, thin and blonde, yet his resemblance to Mamma Wolf, his sister, was unmistakable.
"So! We make a little music to-night," he boomed in a rich ba.s.s, "and the audience is set," bowing ironically to Roger, still in the clouds, and Ernest, his head still in the paper. "Where is the Mutterchen?"
"Coming in a minute," called Mamma, from the dining room. "I can hear.
Go ahead."
Elsa sat down at the piano. Papa Wolf opened his "cello case. Uncle Hugo put his silver flute to his lips and played a tentative sweet note. In a moment the strains of Schubert"s Serenade, exquisitely rendered, filled the quiet house. Roger relighted his pipe and let it go out. Whenever over her shoulder, Elsa cast a quick glance at him, his gaze was fastened intently on the ceiling.
For an hour the music continued without interruption. Then the doorbell rang again and Ernest went to answer it.
"Come into the den so we won"t disturb the concert," Roger heard him say. "Rog, come in here, will you?"
Roger obediently made his way into a little room off the dining room, devoted to the men of the household. A short smooth-shaven, sandy-haired man was standing by the reading table. Roger and he shook hands.
"I"ve been talking to Dr. Austin a good deal about your solar heat apparatus, Rog," said Ernest, "and he"s got a proposition to make. Let"s sit down and talk it out."
He pushed a jar of tobacco toward Austin and the three men, eyeing one another with frank interest, settled themselves in the easy chairs which Ernest indicated with a nod.
"I think Ernest said that you represent the Smithsonian Inst.i.tute,"
Roger said. "What do you want to do? Put my engine in your museum?" This with a short laugh.
Austin shook his head. "I see you are about as ignorant as the rest of the world as to the real nature of our work. Confess now!"
Ernest smiled. "I suppose I"ve been reading papers and reports from the Smithsonian for ten years, but until I met you, Mr. Austin, I was certainly vague about who or what the work represented. Go ahead and give Moore the explanation you gave me, will you?"
"Well," began Austin, "an Englishman named Smithson left his estate to his nephew named Hungerford with the stipulation that if Hungerford died without heirs, the state was to go to found the Smithsonian Inst.i.tution in America. Hungerford obligingly died without issue. It was in 1835, I think, and after a great deal of red tape, about half a million dollars was turned over to the American Congress to go to work with.
"Of course, Congress did considerable false stepping but finally the Inst.i.tution was organized with the avowed purpose of increasing and diffusing knowledge. Rather a large program, eh! It was proposed to carry this program out by stimulating talented men to make original researches by offering prizes, by appropriating every year a sum of money for particular researches and by every year publishing reports on the progress of difficult branches of knowledge.
"The original bequest has been increased until now the Inst.i.tution has use of the income on a million dollars. You"ll be surprised to know how much real work has been done by this very little advertised branch of our government. For example, out of the system of weather observation developed by the Inst.i.tution grew the United States Weather Bureau. The United States Ethnological Research is all done by us--as witness the monumental studies of our American Indians. Powell"s great explorations were fathered by the Smithsonian and so were Langley"s experiments in flying machines as well as his studies of solar heat."
"My word!" exclaimed Roger, "so they were!"
"When I was in the northern part of the state, last summer, studying certain Indian mounds, I ran across one of your fellow instructors who mentioned your work in heat engineering. I"ve always been much interested in that line of research, so when I came West again I tried to get in touch with you."
"I"m not hard to reach, surely," said Roger.
"Oh, yes, you are," returned Austin.
"It was this way, Rog," Ernest"s lazy, gentle voice interrupted. "I kept Dr. Austin away from you until I felt that there was some hope. I didn"t want you to have another disappointment."
"As I got your idea from Mr. Wolf, it seems to me that the Smithsonian might be glad to back you in further experiments," said Austin.
Roger"s thin face flushed as it was apt to do when his work was under discussion. "This is mighty kind of you, Dr. Austin, but my work has gone beyond the experimental stage. I"m ready to erect Solar Power Plants if I can find the money."
"Rog, you"re not ready!" cried Ernest, with unusual vehemence. "You"ve no idea of the troubles you"ll be up against when you try actually to erect a working plant, in a hot country."
"I"m not afraid," returned Roger shortly. "One thing is certain, I"m not going on experimenting any longer."
"My understanding of your device is, that it is practical only in tropical or semi-tropical climates," said Austin.
"This first device is, yes," answered Roger shortly. "If I can ever get this one launched, I shall take up other climates."
Austin eyed Roger keenly for a moment, then he said suddenly,
"Why don"t you let me see your plans? We might possibly have something to say that would interest you."
"Oh, of course! I wish I had some of them here. And it"s too late to go up to the laboratory to-night."
"Wait a moment, Roger! Wait a moment," exclaimed Ernest. "Praying that we"d get to this point to-night, I brought down a set of drawings." He unlocked a drawer of the table and pulled out a roll of paper.
Roger spread some of the sheets on the table and the black, the yellow and the sandy heads bent over them.
