"Is that gentleman your father, Mr. Halford?" said Mary, simply. "I think he is a very handsome old man; that silvery white hair always looks to me beautiful when accompanied with dark eyebrows and eyes."

"My father would feel extremely flattered if he heard your opinion of him, Miss Armstrong," said Henry Halford.

"I am not flattering," replied Mary, "I am only giving my opinion, and you have not told me the name of that gentleman opposite. He looks clever."

"Why, really, Miss Armstrong, I shall begin to be afraid of your opinion about myself if you are so quick at reading character. That gentleman is Professor Logan, whose address at the Royal Society has made such a stir in the scientific world."

"Oh, I am so glad to meet him!" she exclaimed. "I know he must be clever because papa is talking to him so earnestly, and I read his address at the Royal Society in the Times."

"Did you, indeed, Miss Armstrong?" said Henry, in a tone of surprise.

"Certainly I did, and with very great interest. Is there anything very wonderful in that, Mr. Halford?"

"I will put a few questions to this young lady who expresses her interest in abstruse subjects," he said to himself. "Perhaps after all it is merely a smattering of knowledge which she possesses, and a wish to be thought a 'blue.' Are you fond of scientific subjects, Miss Armstrong?" he asked, with something akin to satire in the tone of his voice.

But Mary Armstrong did not detect it; she replied unaffectedly—
