On the August afternoon on which our story opens Stephen Kane was to begin the final assembling of the parts of his machine, after which he could test it in real flight. He needed Orissa’s assistance to help him handle some of the huge ribbed planes, and so she had promised to come home early.

It was not long before she entered the hangar, arrayed in her old gingham, which allowed her to move freely. The two became so interested that Mrs. Kane almost missed her dinner in spite of the girl’s promise; but Orissa did manage to tear herself away from the fascinating task long enough to prepare the meal and serve it. Steve came in and tried to eat, for he was at a point where he could do nothing without his sister’s help; but neither of them was able to swallow more than a morsel, and as quickly as possible hurried back to their work.

Mrs. Kane, although totally blind, knew her way about the house perfectly and was able to take care of herself in nearly all ways; so when bedtime came she abandoned her monotonous knitting, played a few pieces on the pianoforte—one of her few amusements—and then calmly retired for the night. She never worried over the “children,” believing they were competent to care for themselves.

It was long past midnight before Steve got to a point where he could continue without Orissa. “In about three days more,” he said, as they washed up and prepared to adjourn to the house, “I will be able to make my first flight. Shall we wait till Sunday, Ris, or will you take a day off?”

“Oh, not Sunday,” she replied. However eager her brother might be she had never yet allowed him to work a moment on a Sunday, and Steve deferred to her wishes in this regard. “We’re pretty busy at the office and Mr. Burthon was inclined to be a little cranky to-day; but I’ll manage it somehow, just as soon as you are ready.”

“What sort of a fellow is Burthon?” asked her brother, somewhat curiously.

“Why, he stands well in the business world, I’m told, and is very successful in handling large tracts of real estate,” she replied. “Also, he seems a gentleman by birth and breeding, yet a queerer man I never met. His chief peculiarity is in being very absent-minded, but he does other odd things. Yesterday he refused to sell a piece of land to a customer because he did not like him, and he told the man so with rude frankness. One day I discovered he had cheated another man out of six hundred dollars. I called his attention to what I described as a ‘mistake,’ and he said he robbed the man on purpose, because he had been snobbish and overbearing. He gave the six hundred dollars to a poor woman to build her a house with, saying to me that he had once committed a serious crime for which this was in part penance, and soon after he platted a lot of swamp land down near San Pedro and advertised it as ‘desirable residence property.’ Really, Steve, I can’t quite make out Mr. Burthon.”

“He seems to have good and bad points, from what you say,” observed her brother, “and I judge the two qualities are about evenly mixed. Is he nice to you, Ris?”

“He is always polite and respectful, but most of the time he doesn’t know I’m in existence. When he gets one of his absorbed fits his eyes look right through me, as if I wasn’t there.”

“Perhaps he is thinking out some big schemes. Is he a rich man?”
