His companion looked up with a violent start.

“Well, I guess. What of him? I’m not likely to forget him easily. There is just one desire I have in life which dwarfs all others to insignificance, and that is to stand face to face with Mr. Zachary Smith,” Grey finished up significantly.

“Ah! So I should suppose,” Robb went on. “Those are my feelings to a nicety. But I didn’t quite realize my desire, and, besides, I wasn’t sure, anyhow. A man appeared, just for one moment, at the booking-office door as I happened to pass it. He stared at me, and I caught his eye. Then he beat a retreat before I had called his face to mind––you see, his appearance was quite changed. A moment later I remembered him, or thought I did, and gave chase. But I had lost him, couldn’t discover a trace of him, and nearly lost the train into the bargain. Mind, I am not positive of the fellow’s identity, but I’d gamble a few dollars on the matter, anyway.”

“Lord! I’d have missed fifty trains rather than have lost sight of him. Just our luck,” Grey exclaimed violently.

“Well, if he’s in the district, we’ll come across him again. Perhaps you will have the next chance.” Robb pushed his chair back.

“I hope so.”

“It was he, right enough,” Robb went on meditatively, his cheery face puckered into an expression of perplexity. “He was well dressed, too, in the garb of an ordinary citizen, and looked quite clean and respectable. His face had filled out; but it was his 105 eyes that fixed me. You remember those two great, deep-sunken, cow-eyes of his–––” Robb broke off as he saw Grey start. “Why, what’s up?”

Grey shook himself; then he gazed straight before him. Nor did he heed his companion’s question. A strongly-marked pucker appeared between his eyebrows, and a look of uncertainty was upon his face. Robb again urged him.

“You haven’t seen him?” he asked.

“I don’t know,” replied Grey.
