There was little or no sea on, as the tide was near the turning, and the cat-boat was rocking softly to the little waves when Fanny came aft again. Lawrence's head was still hanging back, his lips were parted, and his eyes were half open, showing the whites in a rather ghastly way. With strong arms the young girl half lifted him, and let him gently down upon the cushions in the stern-sheets. Then she leaned over the side and wetted her handkerchief and laid it upon his bruised forehead. The cold water and the change of position brought him to himself.

He opened his eyes and looked up into her face as she bent over him. Then, all at once, he seemed to realize what had happened, and with an exclamation he tried to sit up. But she would not let him.

"Lie still a minute longer!" she said authoritatively. "You'll be all right in a little while."

"But it isn't anything, I assure you," he protested, looking about him in a dazed way. "Please let me sit up! I won't make a fool of myself again—it's only my heart, you know. It stops sometimes—it wasn't the knock."

"Your heart?" repeated Fanny, with greater anxiety than Lawrence might have expected. "You haven't got heart disease, have you?"

"Oh no—not so bad as that. It's all right now. It will begin to beat very hard presently—there—I can feel it—and then it will go on regularly again. It isn't anything. I fancy I smoke too much—or it's coffee—or something. Please don't look as though you thought it were anything serious, Miss Trehearne. I assure you, it's nothing. Lots of people have it."

"It is serious. Anything that has to do with the heart is serious."

Lawrence smiled faintly.

"Is that a joke?" he asked. "If it is, please let me sit up."

"No—that isn't a reason," answered Fanny, laughing a little, though her eyes were still grave. "You must lie still a little longer. You might faint again, you know. It must be dangerous to have one's heart behaving so strangely."
