First of all he moved his arms and legs to ascertain whether any of his limbs were broken. Reassured on this point he felt next for the diamond pin. To his great relief it was safe.

All about him was confusion. He was just thinking of getting up when a man came along with a lantern, and stooping over, began to feel in the pockets of a prostrate figure lying near by. Instantly Mark was on the alert, for he felt sure that this man must be a thief intent on robbing the victims of the disaster.

He peered into the face of the robber who fancied himself unobserved, and with a thrill of excitement he recognized the man whom he had met twice before in New York, and who had called himself Hamilton Schuyler. At the same time, glancing at the upturned face of the recumbent figure he saw that it was his uncle, Solon Talbot, still insensible.

Schuyler had just drawn Mr. Talbot's watch from his pocket, when Mark, putting a whistle to his mouth, blew a sharp note on it.

Schuyler started, let the watch drop, and rose in a state of nervous alarm.

"What was that?" he cried.

"Mr. Hamilton Schuyler," said Mark calmly, "that gentleman will have occasion for his watch. You had better let it alone."

"I was only going to take care of it for him," muttered Schuyler.

"You'd take care of it well," retorted Mark.

"Who are you?" demanded Schuyler, and he stepped over to where Mark lay and peered into his face.
