"Oh, then that is why we are honoured with a visit, is it?"

"I—I was not coming to see you to-day, was I, Mrs. Cameron?" said
Harry, colouring.

"No, that is a fact," said the lady. "He was going right by, but I called him in."

"Ah, well, we will forgive you. Stop and have tea with us."

Harry's acceptation showed that he was only too glad, and after the pleasant meal in the verandah, there was an interesting hour to be spent in the doctor's curious compound of surgery, study, and museum, where plenty of fresh insects had to be examined.

Mrs. Cameron displaying a bright, girl-like interest in everything, till called away to give some instructions to her servants.

"How Mrs. Cameron must help you, Doctor!" said Harry. "I did not know that she was so clever at pinning out moths."

"Look here," said the doctor sternly, "have you been saying anything to her about what you told your father you heard said in that boat?"

"Not a word, sir."

"That's right. I'm glad of it; but I was afraid."
