CHAPTER III

QUILQUA THE MYSTERIOUS

He was a suave, polished, open-shirted Arab, who appeared the morning after they had left Port Said and the Suez far behind, and who smiled at Louis Schoverling with the air of old acquaintance. The American sprang up with extended hand.

"Why, Selim! I had no idea you were aboard!"

"Neither had the authorities at Port Said," rejoined the Arab softly. The explorer raised his eyebrows, and Jack nudged Charlie significantly. A moment later they were being introduced, and von Hofe was explaining the object of their journey.

"It should interest Mr. ben Amoud," smiled the General, "as he is one of the largest Arab dealers in ivory—and other things—on the Coast."

Selim, much to Charlie's surprise, spoke fluent English, enjoyed his cigar as much as did the explorer, and was not as swarthy as their Italian captain. He sat quietly beneath the awning, his wide hat shading his face, and would easily have been taken for a German or Boer, with his flowing beard and European clothes. Most of the Arabs on board wore the burnous and sandals, and Charlie wondered if there were any reason behind this European garb.

The trader heard of their expedition, and gravely complimented von Hofe on his work, of which he spoke with some knowledge, until the doctor beamed genially.

After a pause Selim turned to Schoverling. "Much has happened in the two years since I last saw you. You have not, by any chance, heard of one who calls himself 'Me debbil man'?"

Charlie started, but Jack, his deep black eyes suddenly afire, gripped his arm. Von Hofe stared, and the Arab gazed at Schoverling, whose face never changed.

"Yes," replied the explorer, quietly. "We are all friends of his."

The Arab's gaze darted to one of the deck-hands, lounging on the rail near by. Charlie saw ben Amoud rise, step to the man's side, and hiss something. The man looked startled; then his face changed and he slunk away. Selim, his narrow eyes glittering, returned to his deck-chair and settled himself comfortably.

"Now we can talk, my friends. Mr. Schoverling, have you ever heard of Lake Quilqua?"

The American looked puzzled. "Can't say I remember the name, Selim. Where is it?"

"Ah, many men have asked that question!" and Selim's white teeth shone. Charlie stole a glance at Jack. His dreams of the mysterious East were being rapidly realized! "No one has ever answered it, however. It is one of those odd native yarns that are generally founded on fact, though you white men disbelieve them. Here it is for you:

"Two years ago rumors began to drift to certain of us that somewhere, far down from the Abyssinian border in that desolate land north of the Lorian Swamp, there was a lake. The tale was given me in fuller form by one of my own Arabs who had got lost and found his way out to die, crazed and raving of horrible things, only a few months ago.

"This lake, it seems, is fed by underground springs—hot springs, that spout up and fall like fountains on the water; its outlet is also by an underground river, so that the lake lies, sweltering in the sun and surrounded by desert and jungle and marsh, where no people live."

Ben Amoud turned to the calmly interested German. "You, Doctor von Hofe, are a scientist. Granted such a body of water, at an average temperature of ninety to a hundred degrees Fahrenheit; would animal life in it and near it be liable to any change in average size?"

The big man stroked his beard reflectively, pulling at his pipe.

"Possibly," he admitted at length. "But only one way. If animal life could exist at such a temperature, it would perhaps be much larger than elsewhere. For instance, a buffalo lives much in the water. In such a place as that, a buffalo's great-grandchildren would be larger, and so on through succeeding generations, each a little larger. Yes, it iss possible—but nod probable."

"Do you mean," cried Charlie, unable to repress his eagerness, "that there are giant animals there?"

The Arab smiled and waved his hand. "It is but a tale, remember. See, I have heard that in this lake are great serpents of monstrous size. That, as our friend has just said, there are such buffalo there as were never seen, and that evil spirits dwell on an island near the reed-encircled shore. But there is one thing more, that might interest you; indeed, it was my reason for telling you the story.

"Not only the wandering natives, but my own Arab, have raved of a tremendous elephant, a rogue, who dwells near there. He is said to be of great size, very wicked, and cursed by Allah with the desire to fight men. His size is said to be that of a mountain—and in truth I doubt if any man has ever seen him and lived to tell of it. There, my friends, would be a conquest worthy of your skill!"

Von Hofe grunted, but Charlie saw that his blue eyes were never off the face of the Arab. Jack sat listening with all his ears.

"What's a 'rogue'?" he asked.

"Wait till you see one and you won't need to ask. A rogue is a big bull elephant who's broken away from his herd and lives by himself in the jungle. He's usually a man-fighter, and doesn't think anything of attacking a whole herd of elephants. He's an outlaw, and he's a bad citizen to meet.

"But I hardly think, Selim," continued the General with a smile, "that we will penetrate to such a place. All we wish is a couple of very large bulls; the others of the groups can be picked up nearer home, but it is essential that we get magnificent tuskers."

"And I have told you where to get the best of all tuskers," rejoined Selim seriously. "There is some foundation for such a tale, believe me. I am not at liberty to tell you more, but perhaps you, Mr. Schoverling, could imagine a friend of yours who would be very likely to try the truth of the yarn."

Charlie's quick eyes roved from face to face. He had not fought with the world for most of his life and emerged unable to read men's faces, young as he was; and he knew enough of Jack by this time to feel confident that the other was losing nothing of what went on.

At the Arab's last words a glance flashed between him and the explorer. Von Hofe was frankly puzzled over these references to an unknown person, but he asked no questions, wisely. It was the explorer who finally spoke.

"Yes, I can imagine such a man, Selim. But we are in no way connected with him, nor are we acting in conjunction with him. He told me, the day he left New York, that he had something big on hand, and would perhaps meet me later."

The Arab smiled slightly and tossed his cigar over the rail. Charlie had jumped at the conclusion that they spoke of Mowbray, the ivory raider, when Selim had first uttered the catch-phrase or password. At Schoverling's reply he knew that he had been right, and watched eagerly for more.

But the conversation shifted to other things, and during the morning there was no more said of the mysterious lake. The two boys got off by themselves and discussed the matter, but arrived nowhere.

"Prob'ly Mowbray is making a try for that Quilqua business," concluded Jack sagely. "It sounds mighty good to me, old boy?"

"Here too," agreed Charlie. "But Selim laid it on too thick, with sea serpents and elephants like mountains. Bet a dollar to a pine chip that he had some axe to grind with the General. You wait and see."

"Mebbe," conceded Jack doubtfully. "He's a slick-lookin' proposition, Chuck. I saw the lines of a gun in his coat pocket, too. He didn't do much grinding, anyhow. The General didn't fall for his line of talk worth a cent. Well, let's get back; it's almost time for lunch—or what do they call it here? Tiff 'em?"

"Tiffin," chuckled his friend; "same's they do in India. There's a heap of Indians all down the coast, 'cause it's a Mohammedan country an' they don't lose caste by coming over to work."

All of which explanation was largely lost on Jack. Charlie knew a good deal of the East Indians, having witnessed most of the Hindu immigrant riots in western Canada, and he was frankly interested in them as a race.

When they returned to the after awning they found Selim just saying good-bye. He was to leave the ship at Ras al Kyle, a port on the Italian Somaliland coast, and they were nearly due to reach there. So he suavely bowed himself away, in odd contrast to his Boer-like appearance, and the boys immediately deluged the General with questions. Dr. von Hofe rumbled out a laugh.

"Would you prefer my absence, General? I—"

"Nonsense, Doctor!" broke in Schoverling sharply. "Here is all I know," and he told the big German of meeting Mowbray, and of the latter's words.

"So!" drawled von Hofe. "Then, this Selim ben Amoud is who?"

"I have heard that he is the wealthiest Arab on the east coast," replied the American. "You noticed, I suppose, what he first said?"

Charlie nodded eagerly.

"Privately, I have no doubt that he is a slaver," went on the explorer. "He has a hand in everything, and is always in hot water with the British authorities. He was trying to find out whether or not our expedition had anything to do with that of Mowbray. I have met him before and we know each other slightly."

"Well," asked Jack, "is Mowbray going to the magic lake?"

The explorer laughed. "Who knows? The whole yarn may be a bluff—probably is. Selim would like the British to think that Mowbray's party is merely exploring, and perhaps he thinks we will spread the news, in which he is mistaken. Or, he may have been honest in the matter; you can never tell what lies behind his words."

At this Charlie's face fell slightly. He had been intensely interested in the Arab's tale, and the thought that it was a put-up job did not appeal to him in the least.

"But wasn't it true?" he inquired, disappointed. "It sounded pretty good to me!"

"Frankly, Charlie, I don't believe a word of it. You can hear yarns like that wherever you go, and they usually pan out pretty small—just like Jack's story of the mammoth up in the north. You noticed the password, 'Me debbil man'? Well, there isn't a particle of doubt in my mind that Mowbray and Selim are parts of a big underground concern for illicit trading. I don't for a minute think Mowbray would traffic in slaves, but of course he's the biggest ivory raider in the game."

"Then it's a sort of conspiracy?" shot out Jack quickly. "Any chance of our gettin' mixed up in the business?"

"Not a bit of it," asserted the explorer, with a smile at von Hofe. "I'll answer for that, Jack. Selim is satisfied, and we'll probably never hear from him or Mowbray again. Our own trip is perfectly fair and square, the authorities will know everything we do, and we can't afford to soil our fingers with anything crooked. It doesn't pay."

"That is why," struck in Dr. von Hofe, "I came to you. 'Schoverling,' they told me, 'he is straight.' It is a good reputation to have, my friend."

The boys nodded, understanding. A look of gratification crossed the explorer's face, such gratification as comes to a man when he knows that he has won the esteem of other men.

"We are not looking for hot water and sea serpents," went on the doctor with a broad smile at the boys. "We are looking for elephants, let us remember, please!"

With that, the topic of Lake Quilqua was promptly dropped. At Ras al Kyle, Selim ben Amoud went ashore—this time wearing sandals and burnous—and the Mombasa took up her interrupted journey south. But late that night, as the boys swung into their bunks, Jack gave vent to his long-repressed thought.

"Chuck, I wish to thunder we were goin' to hunt for that lake!"

"Forget it," advised Charlie. "Von Hofe isn't paying expenses for us to chase around after sea serpents. Anyhow, Jack, when you come to think it over it doesn't stand to reason that there's any such place as that. There's a heap of sense in what the General said. I've heard that Injun yarn about the mammoths up north; but you know's well as I do that when it comes down to hard pan there's nothin' to it. Same with this magic lake."

"Guess you're right," sighed Jack regretfully, turning out the light. While the boys were turning in, Dr. Gross von Hofe was replying to a certain question put to him by the General, before they retired.

"Yes, my friend, it could be. Lieutenant Graetz found just such gigantic buffalo at Lake Bangweolo, and was all but killed by them. He has promised that I shall mount one, when he is able to undertake a second expedition to bring home specimens. But elephants and sea serpents—ach, no! Such a yarn is crazy."

"So crazy as a loon," laughed Schoverling, and said good night.
