"What did your visitor look like?" inquired Cora.

"He was tall and dark and very stooped," replied Mrs. Robbins. "Besides this, I noticed he wore boots with his trousers outside, as a farmer or clammer wears them."

"I fancy the girls will be timid to-night," Cora remarked, as they started back to the cottage.

"Yes, this has been what you might call a portentous evening," agreed Walter, "and I do declare I think Miss Robbins is—well—nice, to put it mildly."

"Wallie," said Jack. "I will have an awful time with you, I can see that. But you are young, boy, very young, and she is already a doctor, so maybe there is hope—she may be able to cure you."
