Thus he raved until he was almost completely exhausted, and his physical self, unable to bear the strain any longer, caved in completely. His head dropped forward on his chest and his hands fell helplessly over the arms of the chair. He was unconscious for nearly a quarter of an hour and it was only by administering violent restoratives that Jack and the engineer managed to make the man himself once more.
For some time the four sat staring at the helpless engineer. Finally Mr. Ryder spoke.
“Why did you do this deviltry, Nedham?” he asked with a trace of disappointment in his voice.
“I—I—well I was ambitious—and—I guess a little jealous of you too,” said Nedham weakly. “You know you only beat me out by two points in the competition for chief engineer and—well—I couldn’t help feeling bitter toward you. I wanted your job, and I wanted it badly, and from the time you appointed me your assistant I started to scheme ways of getting you out.”
“But what good would all your plant-wrecking have done? Why did you put sand in the generators and disrupt the place in general?” queried the engineer.
“Well, first off I hoped to frighten you into resigning. I—I—thought perhaps when you found you had traitors among the men at the plant you might fear for your own safety and resign, but when I learned how angry Huerta grew with each new occurrence and how often he called you on the telephone and raised the devil with you I saw a new way of getting your job. I concluded that if the trouble was kept up long enough the President would dismiss you entirely as an incompetent manager and put me in charge. The day they called you down to Mexico City and had you up before the directors I felt mighty confident that you would not last long.
“You brought this youngster back with you and from then on my plans began to go wrong. I saw you two pass the office the first night Jack was here. I followed you into the generating room and hid behind one of the machines. I saw you sprinkle the cement dust and I knew you were setting a trap. But as I watched it suddenly occurred to me that you were unconsciously giving me a capital opportunity of throwing you off the trail entirely. Thereafter I decided to work with my feet bared so that you would think a peon was doing the damage. I forgot completely about the scar on my heel until it was too late.”
“But the plans; the drawings of the lightning arrester. How did you even know of their existence? I kept my work on that appliance very secret indeed,” interrupted Mr. Ryder.
“Well, after I watched you set your trap I followed you back to the cottage for I was curious to hear what you might have to say about the situation. I saw the bundle of drawings drop from your shirt. Also I saw where you put them. And although I did not have the slightest idea what the plans were about I decided that so long as I had gone that far I might just as well take a look at your private papers too. I thought perhaps they were orders or instructions you had received from Huerta that day.
