“But before that?” interrupted Mr. Sheston, settling himself comfortably into an arm-chair.

“We were talking about Diana,” said the other Diana. “It’s my name, and Rachel had been reading about her in the Bible. And my father painted a picture of her, so she was asking me about it.”

“Well,” returned Mr. Sheston, “let’s go on talking about Diana, because there’s a great deal to say. There was a famous temple built for her once upon a time, wasn’t there? Where was it?”

“At Ephesus,” said Rachel promptly.

“And where is Ephesus?”

“In Asia Minor,” answered Rachel again. “By the sea. Not so very far from Rhodes,” she added, with a meaning glance.

Mr. Sheston got up, and to the children’s surprise, altered the position of his arm-chair till it faced the window. Then he fetched two other chairs, and placed one on either side of his own seat. This done, he took from his coat pocket a leather case, and out of the case drew a photograph. Then he pointed to the two small chairs on either side of the big one.

“Sit down, one on each side of me,” he said.

When the children, too interested and puzzled to ask questions, had done as he directed, he held the picture in such a position that both of them could see what it represented.

“Is it the temple of Diana?” ventured Rachel as she glanced at the photograph of a huge building.
