"At eleven I sent a messenger to the house on the 'bluff.' The boy returned with the information from the servants that Mr. Grant had not been home. Somewhat alarmed, I sent coolies through the town to all the places where he might have called, but without results. I received your telegram and answered it at once. And that's all I know."

The information was meager enough. Nattie and Mori exchanged glances of apprehension. Their worst fears were realized. That some disaster had happened to Grant was now evident. The former sprang to his feet and started toward the door without a word.

"Where are you going?" asked the Japanese youth, hastily.

"To see Mr. Black," was the determined reply. "The villain is responsible for this."

"But what proof can you present? Don't do anything rash, Nattie. We must talk it over and consider the best plan to be followed. We must search for a clew."

"And in the meantime they will kill him. Oh, Mori, I can't sit here and parley words while my brother is in danger. I know Ralph Black and his father. They would not hesitate at anything to make money. Even human life would not stop them."

"That may be. Still, you surely can see that we must go slow in the matter. Believe me, Grant's disappearance affects me even more than if he was a near relative. I intend to enter heart and soul into the search for him. Everything I possess, my fortune, all, is at his disposal. But I must counsel patience."

The tears welled in Nattie's eyes. He tried to mutter his thanks, but his emotion was too great. He extended his hand, and it was grasped by the young native with fraternal will. The Scot had been eying them with his habitual placidity. The opening of a crater under the office floor would not have altered his calm demeanor.
