“I’ll try once more,” he thought after a long pause, seizing the iron bell rope, and was just about to pull it when a step sounded on the stone passage within, and the huge door slowly swung open.

A tall man with a rather severe cast of countenance stood facing him in silence.

“I must apologise⁠—it is somewhat late,” he began a trifle pompously, “but the fact is I am an old pupil. I have only just arrived and really could not restrain myself.” His German seemed not quite so fluent as usual. “My interest is so great. I was here in ’70.”

The other opened the door wider and at once bowed him in with a smile of genuine welcome.

“I am Bruder Kalkmann,” he said quietly in a deep voice. “I myself was a master here about that time. It is a great pleasure always to welcome a former pupil.” He looked at him very keenly for a few seconds, and then added, “I think, too, it is splendid of you to come⁠—very splendid.”
