It was not love on her part. He knew that. He was sure of it. At least it was the love of the science that he strove to teach--the thirsting of a spirit to know more and more of the wonders of infinite space. She liked to be in his society, to listen to his words. He knew he was gauging Glynne Day's heart, when, with a sensation of misery that swept over him like some icy wave, he went over the hours they had spent together. But, when he tried to gauge his own he trembled, and asked himself why this madness had come upon him, robbing him of his peace and rest--making him so unfit for his daily work. He strode on to and fro, winding in and out amongst the tall pillars of this darkened nature-temple, fighting his mental fight and praying from time to time for help to crush down the madness that had assailed him where he had thought himself so strong. Strive how he would, though, there was Glynne's face ever gazing up into his; and beside it, half-mockingly, in its calm, satisfied content, was Rolph's; and as he met the eyes, there was the cool, contemptuous, pitying look, such as he had seen upon the young officer's face again and again, mingled with the arrogant air of dislike that he made so little effort to conceal. For a time Alleyne had been growing calmer; his determined efforts to master himself had seemed as if about to be attended with success; but as in fancy he had seen Rolph's face beside that of Glynne, a feeling of rage--of envious rage--that mastered him in turn held sway. But it was not for long; the power of a well-disciplined brain was brought to bear, and Moray Alleyne stood at last with his arms folded, leaning against a tree, thinking that after this mad ebullition of passion, he had gained the victory, and that henceforth all this was going to be as a bygone dream. It must have been by some occult law of attraction that deals with human beings as inanimate objects are drawn together upon the surface of a pond, that Rolph, in contemptuous scorn of the sedative tea that would be on the way in Sir John's drawing-room, and holding himself free for a little self-indulgence, took three cigars from his future father-in-law's cabinet in the smoking-room, secured a box of matches, and, after putting on a light overcoat and soft hat, strolled out on to the lawn. "Been on duty with her all day," he said, with a half laugh, "and a fellow can't quite give himself up to petticoat government--not hers. If it wasn't for Aldershot being so near, it would be awful." Glynne was seated alone in the drawing-room, where the shaded lamp stood on the side-table, deep in a book that she was reading with avidity; and as Rolph, with his hands in his pockets, strolled round the house, he, too, stopped to look in at the window. "There's no nonsense about it," he said, "she is pretty--I might say beautiful, and there isn't a girl in the regiment who comes near her."
