With an impatient gesture she tried to brush the tears from her eyes, and then, without a word, she hastily ran out of the room.

The student of pure science was surprised beyond measure. What had happened? What new blunder had he committed? With all his deep study of things material he was ignorant of things emotional and sentimental. This exhibition of anger and grief in his pretty cousin utterly disconcerted him. He did not know what to do, nor what to think, and he stood in the glare of his lantern for a moment or two in deep thought.

Then he closed the lantern and turning round, examined the shadowy picture thrown upon the wall. It represented a young man and a young woman seated upon the wooden rail of the bridge in the open air, and in most loving embrace. His arm was about her waist, and he was looking in her face. His straw hat hid his features, but the face of the young woman was turned toward the camera that had so perfectly mirrored them both. She seemed to be a young and pretty girl in the more lowly walks of life, and her lover seemed to be a gentleman. What a pity he hadn't looked up! Who could he be? And she? Alma's remark plainly showed that she at least knew the girl, and for some reason was hotly indignant with her.

Thinking he had made trouble enough already, Elmer took one more good look at the picture, and then prepared to destroy it. Something about the young man's hat struck him as familiar. It was a panama hat, and had two ribbons wound round it in a fanciful manner that was not exactly conventional.

He silently opened a shutter, and the picture faded away. He drew up the curtains and looked out on the bridge. The young couple had disappeared. Poor innocents! They little knew how their pictures had been taken in spite of themselves, and they little knew the tragic and terrible consequences that were to flow from the stolen photograph so strangely made. Elmer took the little slide from the lantern, and was on the point of shivering it to fragments on the hearthstone, when he paused in deep thought. Was it wise to destroy it? Had he not better preserve it? Perhaps he could some day solve the mystery that hung about it, and find out the cause of Alma's grief and anger. Perhaps he might help her; and there came a softening about his heart that seemed both new and wonderfully unscientific.

Shortly after this the dinner bell rang, and he went down to the dining-room. Alma sent word that she had a severe headache and could not appear. Mr. Belford was already there, and he looked at Mr. Franklin with an expression that made the young man uncomfortable in spite of himself. Mr. Denny was unusually thoughtful and silent, and conversation between the younger men was not particularly brilliant or entertaining. At last the dreary meal was finished. Mr. Belford rose first and went out into the hall. Mr. Franklin followed him, and saw something that quite took his breath away.

There lay the hat of the photograph, double ribbons and all. Mr. Belford quietly took it up and put it on, and it fitted him perfectly. Elmer stopped abruptly and looked at the man with the utmost interest. The confidential, the chimney builder paid no attention, and quickly passed on out of the front door.

"E. Franklin, you have made a discovery. The pursuit of pure science never showed anything half so interesting as this. You had better raise a cloud on the subject. Gad! It's cloudy enough already!"

This to himself as he slowly went up stairs to his room. Selecting a pipe, he filled it, and finding a comfortable seat, he fired up and prepared to examine mentally the events of the day.

"It was the confidential, making love to some village beauty, supposed to be 'Green,' by name, if not by nature. Alma loves him. That's bad. Perhaps she's engaged to him. Has she a ring? Yes—saw it the other day. The affair is cloudy—and—Gad! Blessed if I don't keep that lantern-slide! It may be of use some day. Come in."
