Still Bob was unconvinced. He could not have explained why, but he felt certain that Van's enthusiasm was feigned. For a second he paused undecidedly on the pavement before the door of the great factory; then shrugging his shoulders he entered, followed closely by his chum.
It was evident that they were expected, for a clerk rose from his desk and came forward to greet them.
"Mr. Hennessey, the superintendent, said I was to bring you to his office when you arrived," he said.
"Thank you."
"You are Mr. Carlton's son, aren't you?"
"Yes."
"I thought you must be. Mr. Hennessey himself is going to take you through the works."
The clerk led the way to the door of a private office, where he knocked.
"Mr. Carlton and his friend are here," he announced to the boy who opened the door. "Tell Mr. Hennessey right away."
The boys had not a moment to wait before a large man with a genial face and outstretched hand came forward.
