The Inca Emerald Part 3

"Hey, Professor!" shouted Jud, above the tumult, "what in time is all this noise, anyway?"

"What noise?" inquired Professor Ditson, abstractedly.

The old trapper waved both hands in a circle around his head and turned to the boys for sympathy. "Sounds like the Cornwall Drum and Fife Corps at its worst!" he shrieked.

"What do you mean, Jud?" said Will, winking at Joe.

"Poor Jud!" chimed in the latter, shaking his head sadly, "this trip too much for him. He hearing noises inside his head."

For a moment, Jud looked so horrified that, in spite of their efforts to keep up the joke, the boys broke down and laughed uproariously.

"You'll get so used to this," said Professor Ditson, at last understanding what they were talking about, "that after a few nights you won't notice it at all."

At the professor's bungalow they met two other members of the expedition. One of these was Hen Pine, a negro over six feet tall, but with shoulders of such width that he seemed much shorter. He had an enormous head that seemed to be set directly between his shoulders, so short and thick was his neck. Hen had been with Professor Ditson for many years, and, in spite of his size and strength, was of a happy, good-natured disposition, constantly showing his white teeth in irresistible smiles. Pinto, Professor Ditson's other retainer, was short and dark, an Indian of the Mundurucu tribe, that warlike people which early made an alliance of peace with the Portuguese pioneers of Brazil which they had always scrupulously kept. Pinto had an oval aquiline face, and his bare breast and arms had the cross-marks of dark-blue tattooing which showed him to have won high rank as a warrior on the lonely River of the Tapirs, where his tribe held their own against the fierce Mayas, those outlawed cannibals who are the terror of the South American forest.

That evening, after dinner, Professor Ditson took Jud and the boys out for a walk along the beach which stretched away in front of them in a long white curve under the light of the full moon. The night was full of strange sounds, and in the sky overhead burned new stars and unknown constellations, undimmed even by the moonlight, which showed like snow against the shadows of the jungle. Professor Ditson pointed out to the boys Agena and Bungula, a n.o.ble pair of first-magnitude stars never seen in the North, which flamed in the violet-black sky. As they looked, Will remembered the night up near Wizard Pond before the bear came, when Joe had told him Indian stories of the stars. To-night, almost overhead, shone the most famous of all tropical constellations, the Southern Cross.

Professor Ditson told them that it had been visible on the horizon of Jerusalem about the date of the Crucifixion. From that day, the precession of the equinoxes had carried it slowly southward, and it became unknown to Europeans until Amerigo Vespucci on his first voyage saw and exultantly wrote that he had seen the "Four Stars," of which the tradition had lingered. The professor told them that it was the sky-clock of the tropics and that sailors, shepherds, and other night-wanderers could tell the time within fifteen minutes of watch-time by the position of the two upper stars of this constellation.

"It looks more like a kite than a cross," interjected Jud. "What's that dark patch in the Milky Way?" he inquired, pointing to a strange black, blank s.p.a.ce showing in the milky glimmer of the galaxy.

"That must be the Coal-sack," broke in Will, before Professor Ditson could reply.

"I remember reading about it at school," he went on.

"When Magellan sailed around Cape Horn, his sailors saw it and were afraid that they would sail so far south that the sky wouldn't have any stars. What cheered them up," went on Will, "was the sight of old Orion, which stays in the sky in both hemispheres," and he pointed out the starry belt to Jud and Joe, with the sky-king Sirius shining above it instead of below as in the northern hemisphere.

As Jud and the boys stared up at the familiar line of the three stars, with rose-red Betelgeuse on one side and fire-white Rigel on the other, they too felt something of the same comfort that the old-time navigators had known at the sight of this constellation, steadfast even when the Great Bear and the Pole Star itself had faded from the sky. As they continued to gaze upward they caught sight of another star, which shone with a wild, blue gleam which rivaled the green glare of the dog-star, Sirius. Professor Ditson told them that it was Canopus, Mohammed's star, which he thought led him to victory, even as Napoleon believed that the planet Venus, seen by daylight, was his guiding star. Then the professor traced for them that glittering river of stars, Erida.n.u.s, and showed them, guarding the southern horizon, gleaming Achernar, the End of the River, a star as bright as is Arcturus or Vega in the northern sky. Then he showed them Fomalhaut, of the Southern Fish, which in the North they had seen in the fall just skipping the horizon, one of the faintest of the first-magnitude stars. Down in the southern hemisphere it had come into its own and gleamed as brightly near this northern horizon as did Achernar by the southern. It was Will who discovered the Magellanic Clouds, like fragments of the Milky Way which had broken up and floated down toward the South Pole. These had been also seen and reported by Magellan on that first voyage ever taken around the world four hundred years ago.

Farther up the beach, Jud and the boys came to a full stop. Before them towered so high that the stars seemed tangled in its leaves a royal palm, one of the most magnificent trees on earth. Its straight, tapered shaft shot up over a hundred and twenty-five feet and was crowned with a ma.s.s of glossy leaves, like deep-green plumes. As it touched the violet sky with the full moon rising back of its proud head, it had an air of unearthly majesty.

Beneath their feet the beach was covered with "angel-wings," pure white sh.e.l.ls eight inches long, shaped like the wings of angels in old pictures. With them were beautifully tinted tellinas, crimson olivias with their wonderful zigzag, tentlike color patterns, large dosinias round as dollars, and many other varieties, gold, crimson, and purple.

Some distance down the beach the professor kept a large canoe, in which the whole party paddled out into the bay. As they flashed over the smooth surface, the clamor of the night-life dwindled. Suddenly, from the bushes on a little point, sounded a bird-song which held them all spellbound, a stream of joyous melody, full of rapid, ringing notes, yet with a purity of tone which made the song indescribably beautiful. It seemed to include the ethereal quality of the hermit-thrush, the lilt and richness of the thrasher, and the magic of the veery's song, and yet to be more beautiful than any or all of them together. On and on the magic melody flowed and rippled, throbbed and ebbed in the moonlight.

Suddenly it stopped. Then from the same thicket burst out a medley of different songs. Some of them were slow and mellow. Others had silvery, bell-like trills. There were flutelike calls, gay hurried twitterings, and leisurely delicious strains--all of them songs of birds which the Cornwall visitors had never even heard. Then Will, the ornithologist of his party, began to hear songs which were familiar to him. There was the musical chuckle of the purple martin, the plaintive call of the upland plover, the curious "kow-kow" of the yellow-billed cuckoo, and the slow, labored music of the scarlet tanager. Suddenly all of them ceased and once again the original song burst out.

"That thicket must be chuck-full of birds," whispered Jud.

Professor Ditson shook his head.

"It's only one bird," he said, "but the greatest singer of all the world--the white banded mocking bird."

Even as he spoke, the songster itself fluttered up into the air, a brown bird with a white throat, and tail and wings broadly banded with the same color. Up and up it soared, and its notes chimed like a golden bell as its incomparable song drifted down through the moonlight to those listening below. Then on glistening wings the spent singer wavered down like some huge moth and disappeared in the dark of the thicket. In the silence that followed, Will drew a deep breath.

"I'd have traveled around the world to hear that song," he half whispered.

Professor Ditson nodded his head understandingly.

"Many and many an ornithologist," he said, "has come to South America to listen to that bird and gone away without hearing what we have heard to-night. Between his own two songs," went on the professor, "I counted the notes of seventeen other birds of both North and South America that he mimicked."

They paddled gently toward the sh.o.r.e, hoping to hear the bird again, but it sang no more that night. As they neared the beach, the moonlit air was heavy with the scent of jessamine, fragrant only after darkness, and the overpowering perfume of night-blooming cereuses, whose satin-white blossoms were three feet in circ.u.mference. Suddenly, just before them, the moon-flowers bloomed. Great snowy blossoms five inches across began to open slowly. There was a puff of wind, and hundreds of them burst into bloom at once, glorious white salvers of beauty and fragrance.

"Everything here," said Will, "seems beautiful and peaceful and safe."

Professor Ditson smiled sardonically. "South America is beautiful," he said precisely, "but it is never safe. Death and danger lurk everywhere and in the most unexpected forms. It is only in South America," he went on, "that you can be eaten alive by fish the size of small trout, or be killed by ants or little brown bats."

Jud listened with much scorn. "Professor," he broke out at last, "I don't take much stock in that kind of talk. Your nerves are in a bad way. My advice to you is--"

What Mr. Judson Adams's advice was, will never be known, for at that moment a dreadful thing happened. Into the beauty of the moonlight, from the gla.s.sy water of the bay soared a shape of horror, a black, monstrous creature like a gigantic bat. It had two wings which measured a good twenty feet from tip to tip, and was flat, like an enormous skate.

Behind it streamed a spiked, flexible tail, while long feelers, like slim horns, projected several feet beyond a vast hooked mouth. Like some vampire shape from the Pit, it skimmed through the air across the bow of the canoe not ten feet from where Jud was sitting. The old trapper was no coward, but this sudden horror was too much even for his seasoned nerves. With a yell, he fell backward off his thwart, and as his legs kicked convulsively in the air, the monster came down with a crash that could have been heard a mile, raising a wave which nearly swamped the canoe. A moment later, the monstrous shape broke water again farther seaward, blotting out for an instant with its black bulk the rising moon.

"What kind of a sea-devil is that, anyhow?" queried Jud, shakily, as he righted himself, with the second crash of the falling body still in his ears.

"That," responded Professor Ditson, precisely, "is a well-nourished specimen of the manta-ray, a fish allied to the skate family--but you started to speak about nerves."

Jud, however, said nothing and kept on saying the same all the way back to the house. Arriving there in safety, he went down to the spring for some water with Pinto, but a moment later came bolting back.

"What's the matter now, Jud?" inquired Will, solicitously. "Did you find another water-devil in the spring?"

"That's just what I did!" bellowed Jud. "When I started to dip out a pail of water, up pops about six feet of snake. Now you know, boys," he went on, panting, "I hate snakes, an' I jumped clear across the spring at the sight of this one; but what do you suppose that Injun did?" he continued excitedly. "Pats the snake's head an' tells me it's tame an'

there to keep the spring free from frogs. Now what do you think of that?"

"He was quite right," observed Professor Ditson, soothingly. "It is a perfectly harmless, well-behaved serpent, known as the mussarama. This one is a fine specimen which it will be worth your while to examine more carefully."

"I've examined it just as carefully as I'm goin' to," shouted Jud, stamping into the house as Pinto came grunting up the path carrying a br.i.m.m.i.n.g bucket of water.

As they sat down for supper, a long streak of black and white flashed across the ceiling just over Jud, who sat staring at it with a spoonful of soup half-way to his mouth.

"Professor Ditson," he inquired softly, "is that thing on the ceiling another one of your tame snakes?"

"No, sir," responded the professor, impatiently; "that is only a harmless house-lizard."

"I just wanted to know," remarked Jud, rising and taking his plate to a bench outside of the door, where he finished his supper, in spite of all attempts on the part of the boys to bring him back.

In front of Will stood a pitcher of rich yellow cream. "You have a good cow, Professor Ditson," he remarked politely as he poured some into a cup of the delicious coffee which is served with every meal in Brazil.

"Yes," agreed the scientist, "I have a grove of them." Then he explained to the bewildered Will that the cream was the sap of the cow tree.

Will was not so fortunate with his next investigation. Taking a second helping of a good-tasting stew which Pinto had brought in from the kitchen, he asked the Indian what it was made of.

"Tinnala," replied the Mundurucu.

"What is it in North American?" persisted Will.

The Indian shook his head. "I not know any other name," he said. "Wait, I show you," he went on, disappearing into the kitchen to return a moment later with a long, hairy arm ending in a clenched fist. Will started up and clasped his stomach frantically, remembering all that he had read about cannibalism among the South American Indians. Even when Professor Ditson explained that the stew was made from a variety of monkey which was considered a great delicacy, he was not entirely rea.s.sured and finished his meal on oranges.

Jud was much amused. "You always were a fussy eater, Bill," he remarked from the porch. "I remember you wouldn't eat mountain-lion meat up in the North when we were after the pearl. You ought to pattern after Joe.

He don't find fault with his food."
