Yet he insisted upon it, over and over again, that he had met Dave before, or, if not the youth, then somebody who looked exactly like him, although older. Pressed to tell his story, he said he had met this man on Cavasa Island, in the South Seas. He also mentioned a crazy nurse and a lost child, but could give no details, going off immediately into a wild flight about the roaring of the sea in his ears and the dancing of the lighthouse beacon in his eyes.
"He must know something of my past," Dave said, when he came away from visiting the old tar. "Oh, if only his mind were perfectly clear!"
"We must wait," answered Oliver Wadsworth, who was along. "I think his mind will clear after awhile. It is certainly clearer now than it was some months ago."
"The man he knows may be my father, or some close relative."
"That may be true, Dave. But don't raise any false hopes. I should not like to see you disappointed for the world."
Dave knew that Phil Lawrence's father was a shipping merchant of considerable standing, owning an interest in a great number of vessels. He went to Phil and learned that the boy was going to take a trip to the South Seas that very summer, and was going to stop at Cavasa Island.
"I am going on business for my father," explained Phil. "It is something special, of which he wishes the supercargo to know nothing." And then he told Dave all he knew of Cavasa Island and its two towns and their inhabitants. After that, Dave sent a letter to both of the towns, asking if there were any persons there by the name of Porter, or if any English-speaking person had lost a child years ago, but so far no answer had been received.
Of course, Phil wanted to know why Dave was so anxious to learn about his proposed trip, and, in the end, the poorhouse boy told his story, to which his chum listened with interest.
"Phil, what would you say if I wanted to go with you on that trip to Cavasa Island?" Dave had said, after his story was finished.
"Do you really mean it, Dave?" had been the return question, and Phil's face had shown his astonishment.
"I do – if matters turn out as I think they may."
"That is, if that old sailor gets around so that he can tell a pretty straight story?"
"Yes."
"Well, I'd like your company, first-rate. But – " Phil drew a deep breath – "I'd hate to see you go on a wild-goose chase. Think of traveling thousands of miles and then being disappointed at the end of the trip. That old sailor may simply be crazy."
"I don't think so. Why should he mention a lost child – a boy?"
"Well, that is the only thing that makes it look as if there was something in the story. But couldn't I do the looking for you?"
"No, I'd prefer to do that myself. Besides, you must remember, that sailor did not come directly from Cavasa Island to this country. So, whoever was on the island – I mean the person I may be interested in – may have gone elsewhere – in which case I should want to follow him."
"I see. Well, Dave, do what you think is best, and may good luck go with you!" Phil had said; and there the conversation on the subject had come to a close.
It was not until a week later that Dave had called on Billy Dill again – to find the old tar sitting on a porch of the sanitarium, smoking his pipe contentedly.
"On deck again, my hearty!" had been the greeting. "Give us your flipper," and a warm handshake had followed.
But the visit had been productive of little good. Billy Dill could remember nothing clearly, excepting that he knew a man who looked very much like Dave, and that that man had been his friend while he was stranded on Cavasa Island and looking for a chance to ship. He said he could recall a bark named the Mary Sacord and a crazy nurse called Polly, but that was all.
"I had a picter o' that man once – the feller that looks like you," he said. "But I dunno what's become o' it," and then he had scratched his head and gone off into a rambling mumble that meant nothing at all. And Dave had gone back to Oak Hall more mystified than ever.
CHAPTER III
THREE CHUMS ON THE RIVER
Down at the boathouse the three boys procured a round-bottomed rowboat, and were soon on the river. Roger took one pair of oars and motioned to Phil to let Dave take the other.
"Let him do the most of the rowing – it will help him to forget his troubles," he whispered, and Phil understood.
It was a beautiful afternoon in the early summer, with just the faintest breeze stirring the trees which lined the river bank on either side. The boys pulled a good stroke, and Roger purposely kept Dave at it, until both were thoroughly warmed up.
"You're improving in your stroke," remarked Dave, as they came to a bend in the watercourse and rested on their oars for a minute. "Perhaps you are training for the boat races."
"Well, I shouldn't mind going into a race," returned the senator's son. "It would be lots of sport, even if I didn't win."
"I am going into some of the field contests this summer," said Phil. "That is, if they come off before I go away."
"When do you expect to start?"
"I don't know yet. It depends upon when one of my father's vessels gets back to San Francisco and ships her cargo."
"I've heard a rumor that the Hall is to be shut up early this summer," said Dave. "The doctor is thinking of building an addition before the fall term begins, and he wants to give the masons and carpenters as much of a show as possible."
"Do you remember that day we were on the river, and Gus Plum ran into us with that gasoline launch?" observed Phil. "My, what a mess we were in!"
"I've had trouble with him ever since I clapped eyes on him," answered Dave.
"Oh, let's talk about something else!" cried Roger. "No matter where we start from, we always end up with Gus Plum. And, by the way, do you notice how thick he is with Nat Poole since Macklin has refused to toady to him?"
"They are almost of a stripe, Roger," answered Dave. "I know Nat Poole thoroughly. The only difference is that Poole is more of a dandy when it comes to dress."
"Poole says he is going in for athletics this summer," said Phil. "I overheard him telling Luke Watson so."
"Is Luke going into training?"
"I don't think so. He loves his banjo and guitar too much."
"Well, I'd love them, too, if I could play as he does," returned Dave.
"Luke told me he had noticed something strange about Shadow," put in Roger. "He asked me if I knew what made Shadow so worried. He said he hadn't heard a funny story out of him for a week, and that's unusual, for Shadow is generally telling about a dozen a day."
"It is possible that he may be fixing for a regular spell of sickness," was Dave's comment. "That's the way some things come on, you know."
The boys resumed their rowing, and Roger put on a burst of speed that made Dave work with a will in order to keep up with him. Then, of a sudden, there came a sharp click and the senator's son tumbled over backwards, splashing the water in every direction.
"Whoop! look out!" yelled Phil. "I don't want any shower-bath! Did you catch a crab, Roger?"
"N – no, I didn't," spluttered the senator's son, when he had regained a sitting position. "There's the trouble," and he pointed to a broken oarlock.
"That's too bad," declared Dave. "Boys, we shall have to have that fixed before we take the boat back to the boathouse – or else we'll have to tell Mr. Dale." The man he mentioned was the first assistant instructor at the Hall.
"Let us row down to Ike Rasmer's boathouse and see if he will sell us an oarlock," suggested Roger. "He ought to have plenty on hand."
"All right," said Phil; "and, as both of you must be tired now, I'll take my turn," and he motioned to Dave to change seats with him, while Roger drew in his remaining oar.
The man whom Roger had mentioned was a boatman who rented out craft of various kinds. His boathouse was about half a mile away, but Phil covered the distance with ease. They found Rasmer out on his little dock, painting a tiny sloop a dark green.
