"Come down and see me into the boat, Miss Katherine; it won't hurt Mary to be alone, and I want to say thank you for coming to the rescue so promptly the other day," he said.

"I don't want to be thanked, but I will show you the way to the boat with pleasure, if you are afraid of getting lost en route," Katherine said with a laugh, but falling into his mood, because she saw he wished to say something to her alone.

When they were beyond earshot of the open window, he said anxiously: "Don't you think Mary looks very badly?"

"She looks fearfully tired," Katherine answered.

"Yes, that is it. And the tiredness comes from mental strain. Poor Mary! It seems so hard for her to be happy, yet in all her life she has never lacked anything she wanted save one, and even that I am in hopes she will get yet, if only she has the patience to wait for it."

Katherine's heart gave a painful bound. What was this one thing that Mary Selincourt wanted but could not have—yet? But she could not answer the question with any satisfaction to herself, and she stood silently watching while Mr. Selincourt took his place in the boat. Then she turned and went back up the path again: but her feet dragged in spite of herself; it was as if some instinct told her she was going to meet a heartache.

Mary welcomed her back with a smile, and, reaching out her arm, dragged a comfortable chair nearer the couch. "Come and sit here, you poor, tired Katherine. What a shame that you should have had to toil all day, until your very feet ache with tiredness, while I have lain here and sighed because the hours crept along so slowly!"

"But that is only because you could not use your foot; you don't find time drag when you are able to get about," Katherine remarked, setting her head back against the cushions with a sigh of content, for the chair was of a restful pattern, and she was tired enough to feel the cushions a welcome luxury.

"No, indeed, I can always make sure of interest and amusement when I have two feet available for service, but I was not cut out for the peaceful avocation of the couch invalid, and I just loathe inaction. I would rather have had your day," Mary said with a sigh.

"Are you sure? To begin with, you don't know what sort of a day I have had, and to continue, you have never had to work for your living, and don't know how it feels," Katherine rejoined, thinking of the stuffy heat of the store, the flies, the pickled pork, and the molasses, which had all tried her patience so sorely in the latter part of the day.
