is one thing I can't understand," I said. "Some call them the Sandwich Islands and some the Hawaiian Islands. Which is right?"
"That is easily explained, Mark. When James Cook discovered the islands, more than a century ago, he named them in honor of his patron, the Earl of Sandwich. But the real native name is Hawaii nei pae aina, which means, These Hawaiian Islands. I presume Englishmen will call them after the Earl of Sandwich for a long time to come, but Hawaiian Islands is the proper name."
We remained on deck until the last trace of shore had faded from view, and then went below, to put our staterooms into proper order. Dan and Oliver were soon done, and returned to the deck, leaving Dr. Barton and me taking our time and conversing about the country we were about to visit.
"To a person who had never been out of the United States there would be many curious sights in the Hawaiian Islands," said the doctor. "But to you who have been in Cuba, and to your friends who have been in China and the Philippines, it will be different."
"Oh, I dare say I'll see many strange sights even so," I answered. "Each nation has a good many customs of its own. I understand the Kanakas are quite different from the other people who inhabit the islands of the Pacific."
"They are different, as different as the ancient Moors were from the real Africans. They—— What do you want, Dan?"
For Dan had suddenly appeared, somewhat out of breath.
"We've made a discovery," said he to me. "That one-armed sailor is on board as a steerage passenger, and Oliver caught him studying a paper that looked a good deal like that lost map."
CHAPTER V.
THE ATTACK ON SHIPBOARD.
"You are certain he had the map?" I cried.
"It looked very much like it—was the same size and just as rumpled and yellow."
"Why didn't Oliver demand to see it?"
"As soon as the sailor caught sight of us he jammed the paper into his pocket and hurried down into the steerage."
"And what is Oliver doing now?"
"Trying to get permission to visit the steerage and interview the fellow," returned Dan, as he and I hurried on deck.
We soon found Oliver, who was accompanied by one of the under officers. Matters were briefly explained, and all four of us descended into the steerage, which was as clean and light as could be reasonably expected.
For some time we could not locate the one-armed man, but at last spotted him, apparently asleep in a corner devoted to male passengers. He opened his eyes slowly when shaken by the officer of the ship.
"We want to talk to you," said the officer. "What is your name?"
"I am not ashamed of that," was the bold answer. "It is Caleb Merkin."
"These young men want to talk to you."
"I want to see that paper you were reading awhile ago," put in Oliver.
"This paper?" and Caleb Merkin held out a copy of one of the San Francisco daily newspapers.
"No; that document which belongs to me."
"I haven't anything belonging to you, young fellow," blustered the one-armed man, getting up. "Don't you dare to say I have, either."
"Do you deny that you were reading a bit of parchment yellow with age?"
"I certainly do."
Oliver turned to Dan. "What do you think of this?"
"He isn't telling the truth," was Dan's reply.
"Why don't you search him and his belongings?" I suggested.
"Do it, if you dare!" burst out Caleb Merkin. "I'm an honest sailor. Who are you, anyway? I never saw you before."
"Perhaps there is some mistake," said the ship's officer nervously. "You don't want to accuse the wrong man."
"I know this man, and so do my friends," answered Oliver. "He is a thief—and I'm almost certain he has that paper."
"Was the paper of such great importance?"
"Why, of——" Oliver was about to say, "of course," when I checked him.
"No, it wasn't of much consequence, but my friend was keeping it to prove that the man who got it up was insane," I put in. "He wants the sheet, that's all. It's of no value in itself."
At my words I saw Caleb Merkin's face fall and knew what I had said had had its effect. If he had had any idea of hunting up that treasure for himself I felt certain he would now lose a good deal of his interest in the matter.
Oliver at once understood the ruse I had employed, and so did Dan, and both smiled behind Caleb Merkin's back. For a moment there was an awkward pause all around.
"Do you make a formal complaint against this man?" said the officer, at length.
"Don't do it," whispered Dan. "It will only make a lot of trouble."
"But the map——" whispered Oliver in return.
"We'll do better by saying nothing and keeping our eyes on this Merkin," I said. "You can wager he has hidden the map where it can't be found through an ordinary search."
"Well, I won't make a formal complaint," said Oliver aloud. "But I shall remember you," he added to the sailor.
"And perhaps I'll remember you," was the bold answer; and then we three boys left the under officer and walked on deck.
"I'll wager that rascal is after the treasure," said Oliver. "What gets me is, how did he get money to pay his passage to Honolulu?"
"More than likely he stole it," I answered. "If he would steal from your family he wouldn't hesitate to steal from somebody else."
"That must be it," said Dan. "We must keep a strict watch on Mr. Caleb Merkin, especially after we arrive in port."
Dr. Barton was curious to know what the trouble was about, and as Dan vouched for his honesty, we told him about our mission, after he had promised to keep it a secret. We also showed him the duplicate map and the description, both of which he examined with interest.
"I'm afraid it is rather a wild goose chase," he said. "Still it will do no harm to look the matter up. I expect, after a brief stop in Honolulu, to visit the volcano myself, and we may run across each other out there, and, if we do, I'll help you all I can—if you'll accept my services."
As I have said, Dr. Barton had visited the islands before, and during the next few days of the trip, days when the weather was most delightful, he regaled us with stories concerning this little-known portion of the globe.
"The islands are twelve in number, but only eight are worthy of mention," he said. "The largest by far is Hawaii, on which the volcano exists. It is about ninety miles long by seventy miles wide. North of it is Maui, next in size but much smaller, and then to the northwest come Molokai, Oahu, Kauai, and Niihau. West of Maui lie Lanai and several smaller islands, including one upon which is located a leper settlement, which, fortunately, is gradually dying out."
"Gracious! we don't want anything to do with lepers!" cried Dan.
"You won't get near them—unless you visit the island on purpose," returned the doctor. "As you know, Honolulu is situated on a beautiful bay on the south shore of Oahu. It is the principal city, and has steamship connections with the United States, China, Japan, Australia, and other important countries."
"And what of the population of the islands?"
