the general manager.

"Nice, isn't it?" Bannon commented. "Now read the postscript, Miss
Vogel." It was in Porter's handwriting, and Hilda read it slowly.
"MacBride & Company are not, however, allowed to erect trestles or
temporary scaffolding in the C. & S. C. right-of-way, nor to remove any
property of the Company, such as fences, nor to do anything which may,
in the opinion of the local authorities, hinder the movement of trains."

Pete's face went blank. "A lot of good this darned permit does us then.
That just means we can't build it."

Bannon nodded. "That's what it's supposed to mean," he said. "That's
just the point."

"You see, it's like this," he went on. "That man Porter would make the
finest material for ring-oiling, dust proof, non-inflammable bearings
that I ever saw. He's just about the hardest, smoothest, shiniest,
coolest little piece of metal that ever came my way. Well, he wants to
delay us on this job. I took that in the moment I saw him. Well, I told
him how we went ahead, just banking on his verbal consent, and how his
railroad had jumped on us; and I said I was sure it was just a

their property, because we couldn't hold the thing up with a balloon.

"He asked me, innocent as you please, if a steel bridge couldn't be made
in a single span, and I said, yes, but it would take too long. We only
had a few days. 'Well,' he says, 'Mr. Bannon, I'll give you a permit.'
And that's what he gave me. I bet he's grinning yet. I wonder if he'll
grin so much about three days from now."

"Do you mean that you can build it anyway?" Hilda demanded breathlessly.

He nodded, and, turning to Pete, plunged into a swift, technical
explanation of how the trick was to be done. "Won't you please tell me,
too?" Hilda asked appealingly.

"Sure," he said. He sat down beside her at the desk and began drawing on
a piece of paper. Pete came and looked over his shoulder. Bannon began
his explanation.

"Here's the spouting house, and here's the elevator. Now, suppose they
were only fifteen feet apart. Then if we had two ten-foot sticks and put
'em up at an angle and fastened the floor to a bolt that came down
