Luther Rockwell scribbled a few lines on a leaf torn from his memorandum book, and gave it to Mark.
"Present that at the office," he said. "Come round next week and see me."
"Yes, sir," answered Mark respectfully, and sprang into the cab.
As he was riding through Madison Avenue he noticed from the window his uncle Solon and Edgar walking slowly along on the left hand side. At the same moment they espied him.
"Look, father!" cried Edgar in excitement. "Mark Mason is riding in that cab."
"So he is!" echoed Mr. Talbot in surprise.
Catching their glance, Mark smiled and bowed. He could understand their amazement, and he enjoyed it.
Mechanically Mr. Talbot returned the salutation, but Edgar closed his lips very firmly and refused to take any notice of his cousin.
"I don't understand it," he said to his father, when the cab had passed. "Doesn't it cost a good deal to ride in a cab in New York?"
"Yes. I never rode in one but once, and then I had to pay two dollars."
