Joan murmured her thanks. They had resumed their stroll. It seemed to her that he looked at her once or twice a little oddly without speaking. “What caused your mother’s illness?” he asked, abruptly.!

There was a famous preacher. He lived the simple life in a small house in Battersea, and consecrated all his energies to the service of the poor. Almost, by his unselfish zeal, he had persuaded Joan of the usefulness of the church. Mr. Airlie frequently visited him. They interested one another. What struck Mr. Airlie most was the self-sacrificing devotion with which the reverend gentleman’s wife and family surrounded him. It was beautiful to see. The calls upon his moderate purse, necessitated by his wide-spread and much paragraphed activities, left but a narrow margin for domestic expenses: with the result that often the only fire in the house blazed brightly in the study where Mr. Airlie and the reverend gentleman sat talking: while mother and children warmed themselves with sense of duty in the cheerless kitchen. And often, as Mr. Airlie, who was of an inquiring turn of mind, had convinced himself, the only evening meal that resources would permit was the satisfying supper for one brought by the youngest daughter to her father where he sat alone in the small dining-room. “So did Archimedes disappear,” he answered with a smile. “The nameless Roman soldier remained. That was hardly the survival of the fittest.”

It annoyed her, that silly saying having come into her mind. She could see them lying there, with their white faces to the night. Surely she might have thought of some remark less idiotic to make to herself, at such a time. Madge finished buttering her buns. “Kant, wasn’t it,” she answered, “who marvelled chiefly at two things: the starry firmament above him and the moral law within him. And they’re one and the same, if he’d only thought it out. It’s rather big to be good.” She took from among the litter a faded photograph and handed it to Joan. “Odd,” she said. “I’ve just turned it out.”
