“What is the business?” Awns asked.

“Manufacturing,” said John.

“Yes,” said Awns, “but what do we manufacture? What is the property to be incorporated?”

“A nail mill to begin with,” said John.

“Where is it?”

“Here in Pittsburgh. Thirty-ninth Street.”

“That’s got me,” said Awns. “I can’t think of any nail mill in Thirty-ninth Street.”

John looked at the bill of sale and improved the address without the slightest change of expression.

“Twenty-ninth,” he said.

The lawyer took the bill of sale, glanced at it, and gave John a curious look.
