"It is mainly on my niece's account that we are so busy to-night," smiled the host.

"She is not ill, sir?" asked Dan in alarm.

"Ill! Oh, dear me, no!"

Mr. Preston laughed most heartily.

"No; she is not in the least ill, Mr. Dalzell, though, on Monday, she may feel a bit nervous toward noon,"

"Nervous—-on Monday?" asked Dan vaguely. It seemed rank nonsense that her uncle should be able to predict her condition so definitely on another day.

"Why, yes; Monday is to be the great day, of course."

"Great day, sir? And why 'of course'?" inquired Dan, now as much interested as he was mystified.

"Why, my niece is to be married Monday at high noon."

"Married?" gasped Midshipman Dalzell, utterly astounded and discomfited by such unlooked-for news.
