Early on the following morning, Nat presented himself at the office on Broadway. He had shined his shoes and brushed his clothes, and presented a very neat appearance. He found Hamilton Dart at his desk, and smoking as before.
"I wish you to go to the post office for me," said the man, as soon as he entered. "Go to the general delivery window and ask for letters for Samuel Barrows. That is my sick brother-in-law who is visiting me from Michigan."
"Yes, sir."
"Of course you know where the post office is?"
"Oh, yes. I've been past there several times."
"You needn't be in a hurry. Wait until they sort the eleven-o'clock mail."
"Yes, sir."
The distance to the post office was a considerable one. But Nat was a good walker, and found it was only half-past nine when he got there. To while away the time he determined to walk out on the Brooklyn Bridge and take in the sights from that elevated structure.
Making his way through the crowd on Park Row, he was soon out on the bridge, and walking in the direction of Brooklyn. There was a stiff breeze blowing, and several times his hat was almost lifted from his head.
Suddenly he heard a shout, and saw a stout man running wildly after some papers which the wind was carrying along the walk on the bridge. The man secured one of the papers, but two others were fast blowing beyond his reach, when Nat rushed up and secured them just as they were on the point of being carried into the river.
