Dr. Bates read the little message several times, and absently dismissed the messenger with a coin, which Sally thought outrageously large, and a muttered worried word or two.

"In a way," he said quickly. "When's the next train for San Rafael, Miss Sally? I've got to be there to-night—right away! Do we have to stand here? Thank you. There's a case Field and I have been watching; he says that there's got to be an operation at eight—" His voice trailed off into troubled silence, and he drew out his watch. "Eight!" he muttered. "It's on seven now!"

"Oh, and you have to operate—horrible for you!" said Sally, taking the car skilfully toward the railroad station as she spoke. "But I don't see how you CAN! You've missed the six-thirty train, and there's not another until after nine. But you can wire Dr. Field that you will be there the first thing in the morning."

"I don't see how I could," said Sally, flushing. "I can take the car home, though, and ask Ferd to do it. But that woman's at the hotel, isn't she? I couldn't go up there and sit outside, with every one I knew coming out and wondering why I brought you instead of Ferd! Elsie wouldn't like it. You must see—"
