"Who's that?" he yelled. Then he saw Ned below him. "Who is that fellow?"
"No friend of yours, Tom, I believe," returned his financial manager in a shaking voice.

"Yis, sir, I'll go Massa Tom," declared the old man.
"Is he a spotter, Ned?" demanded the inventor.
"He's no friend. I am going out by the gate. He's got something there that means harm, I believe. Do you think he's killed, Tom?"
"Only ought to be. Not enough current to kill him. But he's badly burned and—and—well! I bet he won't care to fool around the works again."
