"Oh, well, Ruth," she said, "we will meet to-morrow. So long!"

This was not perhaps the way in which a Fifth Avenue maiden would have parted from her friend, but Maria Stevenson was a free and easy young woman, of excellent heart and various good qualities, but lacking the social veneering to be met with in a different class of society.

"How provoking!" thought Ruth, as she reluctantly took her place beside the Professor, who, unlike herself, seemed in the best of spirits.

"I haf waited here a quarter of an hour to meet you, Mees Ruth," he said.

"I wish you hadn't," thought Ruth, but she only said, "I am sorry to have put you to so much trouble."

"It was no trouble, I assure you, Mees Ruth," said her elderly companion in as genial a tone as his bass voice could assume.

"Let us cross the street," suggested Ruth.

She wished as soon as possible to get out of sight of her shop companions, who were sure to tease her the next day.

"With all my heart," said the Professor. "I should wish to be more alone."

They crossed Sixth Avenue, and walked down on the west side. Ruth was wondering all the while what on earth could have induced the Professor to take such pains to offer her his escort. She did not have long to wait.
