"I don't go there no more. The po-lice, they take there."

"But you had gone there before?"

"Not to play; no."

"Not to play? Are you sure?"

The German considered painfully. "There vass no feet in the
window," he explained, brightening.

Upon that surprising phrase Average Jones pondered. "You were not
to play unless there were feet the window," he said at length. "Was
that it?"

The musician assented.

"It does look like a signal to show that Linder was in," mused the
interrogator. "Do you know Linder?"

"I don't know nothing only to play the B-flat trombone," repeated
the other patiently.

"Now, Schlichting," said Average Jones, "here is a dollar. Every
evening you must come here. Whether I am here or not, there will
be a dollar for you. Do you understand?"

By way of answer the German reached down and listed his instrument
to his lips.
