He did come, and many evenings after, and it was from this old man that Cobb first learned the art of making ozone in quantities. It was not a difficult matter for them to ascertain the various hobbies each possessed. Their conversation soon gave each an insight into the desires of the other for a knowledge of the many things yet unknown, but yet imagined. Their desires being so assimilated, their tendencies so coincident, it was only natural that each should take more than a common liking to the other. But, though he had worked with Colchis in the manufacture and uses of ozone, the latter never had any idea of the grand scheme his friend had in view, for Cobb would not communicate the secret to him for fear that he might divulge it to others. The door of the old house had opened to admit Cobb, and had closed again, leaving him in the hall. There was no light to guide him, but his knowledge of the place and surroundings was such that he found no difficulty in ascending to the little back parlor where Colchis usually sat when not at work. Opening the door, he entered, and was quickly clasped about the neck by a pair of plump white arms, while a face, radiantly beautiful, looked into his, and a red pouting mouth invited the kiss which he quickly bestowed upon it. "Oh, Mr. Cobb, I am so glad you have come! I heard you at the door, and have surprised you! Now, have I not? Say yes; for you know I have!" and the sweet little maiden released him, and shook her delicate finger in a menacing gesture, as if her command could not be disobeyed. Marie Colchis was the only child of Jean Colchis--a beautiful, fair-skinned girl of seventeen, with long, heavy blonde hair; plump in form, with small, fine hands; loving in disposition, with most winsome ways; innocent as a new-born babe. Jean Colchis had kept this sweet girl close to him with a jealous care. She knew no one, scarcely, save her father and Junius Cobb. Witty and bright beyond her years, yet gentle and innocent as a lamb, she had from the very first conceived a girlish love for her father's visitor. And Junius Cobb loved the girl dearly; loved to hear her girlish talk and watch her innocent ways; loved to stroke her hair, and loved to kiss her lips and feel her arms about him. Was there any harm? He was thirty-three, and she was but seventeen. [Illustration] Jean Colchis noted their peculiar love, and smiled. No man was closer to the heart of Jean Colchis than Junius Cobb. Nothing could the latter ask that the old man in Duke's Lane would not have given him--even his daughter, should he seek her. But this, of course, the old man knew was beyond expectation. It would have pleased his old heart, but the disparity of years caused him to believe it to be impossible. And Marie--what were her thoughts and feelings? She loved Junius Cobb--loved him, young as she was, as a mature woman loves the man she would call husband. She loved him with her whole heart, with her very soul.
