_Jeanne D'Arc_ and the boat belonging to the launch cutting a long
broken furrow behind them. Mr. Hand was minding the engine, while the
engineer and owner of the launch, Little Simon--so-called probably
because he was big--stood forward, handling the wheel. Jim was lying
on some blankets and oilskins on the floor of the boat, the doctor
sitting beside him on a cracker-box. Agatha, feeling useless and
powerless to help, sat on the narrow, uncomfortable seat at the side,
watching the movements of the doctor. She was unable to tell whether
doubt or hope prevailed in his rugged countenance.

At last she ventured her question; but before replying Doctor Thayer
looked up at her keenly, as if to judge how much of the truth she would
be able to bear.

"The hemorrhage was caused by the strain," he said at last, slowly.
"It is bad enough, with this fever. If his constitution is sound, he
may pull through."

Not very encouraging, but Agatha extracted the best from it. "Oh, I'm
so thankful!" she exclaimed. Doctor Thayer looked at her, a deep
interest showing in his grim old face. While she looked at James, he

slightly forward, which made him look much fiercer than he ever felt.
Thin white hair covered his temples and grew in a straggling fringe
around the back of his head, upon which he wore a broad-brimmed soft
black hat.

Doctor Thayer would have been noticeable, a man of distinction,
anywhere; and yet here he was, with his worn satchel and his
old-fashioned clothes, traveling year after year over the country-side
to the relief of farmers and fishermen. He knew his science, too. It
never occurred to him to doubt whether his sphere was large enough for
him.

"I haven't found out yet where we are, or to what place we are going.
Will you tell me, sir?" asked Agatha.

"You came ashore near Ram's Head, one of the worst reefs on the coast
