"Well--I don't know," answered Mr. Cray, after considering the point. "I have been--I have been"--

"What?" cried Dr. Davenal, surprised at the unusual hesitation, "Speak out, Mark."

"I was going to say I have been making love to her ever so long," continued Mark, with a laugh. "In fact, sir, we have understood each other for some time past; but as to the precise period that I actually spoke out to her by words, I am not sure when it was."

The contrast between the two men was observable in the silence that ensued. Dr. Davenal grave, absorbed, full of thought and care; Mr. Cray self-satisfied, looking as if neither thought nor care had ever come to him, or could come. He lightly watched the passers-by in the street, over the Venetian blind of the middle window, nodding and smiling to any acquaintances that happened to appear. Mr. Cray had made up his mind to marry Miss Caroline Davenal, and it was entirely out of his creed to suppose that any insurmountable objection could supervene.

"Mark," said Dr. Davenal, interrupting the gentleman as he was flourishing his hand to somebody, "you must be aware that circumstances render it imperative upon me to be more than commonly watchful over the interests of Caroline."

"Do you think so? But, Dr. Davenal, I would be sure to make her happy. I would spend my life in it: none would make her as happy as I."

"How do you know that?" asked Dr. Davenal.

A smile hovered on the young surgeon's lips. "Because she cares for me, sir; and for none other in the wide world."

"I had thought--I had thought that another cared for her," returned Dr. Davenal, speaking impulsively. "At least, a doubt of it has sometimes crossed me."

Mark Cray opened his eyes widely in his astonishment. "Who?" he asked.
