"I don't know," confessed Charley, truthfully. "B-black, I think." "Don't know!" grunted Mr. Grigsby. "After this, notice those things. A man can change his hair, but he can't change his eyes. When you've followed the trail a while, like I have, you'll learn to size a man up at a glance, and never forget him. Kit Carson was a great fellow for that. So was Fremont. Well, the first thing to do is to look for Charley's man. What do you say, Adams?" Charley's father gravely nodded. "I agree. Did you see any of that gang go ashore, Charley? Either of the Jacobs cronies, I mean. Jacobs we saw ourselves, in the town." "No, sir," said Charley. "But they might have gone." "Didn't see them aboard ship, then?" asked Mr. Grigsby. "No, sir; I didn't." "Wait a minute," spoke Mr. Grigsby. "We did glimpse that fellow who tried to use the knife, going into a grog shop. Remember?" "I do," affirmed Mr. Adams. "That accounts for two, then. Well, Charley," and he laid his hand on Charley's shoulder, "it's up to you to find your man for us, and then we'll investigate him. Take a brace, now, and don't feel bad. There's no use crying over spilled milk; you're only wasting time. You simply made a mistake, and everybody makes mistakes once in a while. The thing to do now is to go ahead and correct that mistake, the best you can. We'll help you." What a brick his father was! And so was Mr. Grigsby. Instead of scolding him and confining him on bread and water, or sending him back home, they were standing shoulder to shoulder with him. "The papers don't amount to so tearing much," mused Mr. Grigsby. "You know what the sketch looks like. That assignment of the claim may be important and may not. But of course nobody likes to be robbed." Charley was now all eagerness to retrieve himself and find that man with the iron-gray hair and beard. Out he went, with his eyes open; but though he trudged everywhere, while the ship got under way and steamed, with a cheer, out past the _Panama_ and to sea again, he found no passenger who looked anything like the one wanted. And he didn't see him at the table. Neither, so his father and Mr. Grigsby reported, on coming up after dining, separately, did they. However, while most of the first-cabin and second-cabin passengers were loafing about, that evening, enjoying the long twilight, who should saunter to the Adams party but the long-nosed man himself. He certainly had nerve! "How are you?" he accosted, very pleasantly. "I saw you gentlemen ashore. How'd you make out? Hot place, wasn't it!" "We made out very well, sir," answered Mr. Adams, shortly. "But while we were gone our cabin was robbed. How do you account for that?" "Meaning, I suppose, that you think I can account for it." "Anybody who would tamper with boats would tamper with a cabin, we reckon," growled Mr. Grigsby.
