A week later found the whole party aboard of one of the great South American liners bound for Belem. The voyage across was uneventful except for the constant bickerings between Jud and Professor Ditson, in which Will and Joe acted sometimes as peace-makers and sometimes as pace-makers. Then, one morning, Will woke up to find that the ocean had changed overnight from a warm sap-green to a muddy clay-color. Although they were not within sight of land, the vast river had swept enough earth from the southern continent into the ocean to change the color of the water for a hundred miles out at sea. Just at sunrise the next day the steamer glided up the Amazon on its way to the old city of Belem, seventy miles inland.
"The air smells like a hot, mouldy cellar!" grumbled Jud; and soon the Cornwall pilgrims began to glimpse things strange and new to all three of them. Groups of slim assai-palms showed their feathery foliage; slender lianas hung like green snakes from the trees; and everywhere were pineapple plants, bread-fruit trees, mangos, blossoming oranges and lemons, rows of enormous silk-cotton trees, and superb banana plants, with glossy, velvety green leaves twelve feet in length curving over the roof of nearly every house. Beyond the city the boys had a sight of the jungle, which almost without a break covers the greater part of the Amazon basin, the largest river-basin on earth. They landed just before sunset, and, under Professor Ditson's direction, a retinue of porters carried their luggage to the professor's house, far down the beach, the starting-point for many of his South American expeditions.
As the sun set, the sudden dark of the tropics dropped down upon them, with none of the twilight of higher latitudes. Jud grumbled at the novelty.
"This ain't no way to do," he complained to Professor Ditson. "The sun no more than goes down, when bang! it's as black as your hat."
"We'll have that seen to at once," responded the professor, sarcastically. "In the meantime, be as patient as you can."
With the coming of the dark, a deafening din began. Frogs and toads croaked, drummed, brayed, and roared. Locusts whirred, and a vast variety of crickets and grasshoppers added their shrill note to the uproar, so strange to visitors and so unnoticed by natives in the tropics.
"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 noble 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 space 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, Eridanus, 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 mass 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 shells 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 shore, 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 circumference. 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 glassy 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 brimming 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 reassured 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."
"All I want about food," grunted Joe, "is enough."
That night the whole party slept side by side in hammocks swung in a screened veranda in the second story.
During the night, Jud, who was always a light sleeper, was awakened by a curious, rustling, crackling sound which seemed to come from the storeroom, which opened into the sleeping-porch. After listening awhile he reached over and aroused Professor Ditson, who was sleeping soundly next to him.
"Some one's stealin' your grub," he whispered.
The professor stepped lightly out of his hammock, followed by Jud and the boys, who had been waked up by the whispering. Opening the door noiselessly, the scientist peered in. After a long look, Professor Ditson turned around to find Jud gripping his revolver and ready for the worst.
"You can put up your gun," the scientist growled. "Bullets don't mean anything to thieves like these, and he flashed a light on a strange sight. On a long table stood native baskets full of cassava, that curious grainlike substance obtained from the root of the poisonous manihot and which takes the place of wheat in South America. The floor was covered with moving columns of ants, large and small, which had streamed up the legs of the table and into the baskets. Some of them were over an inch long, while others were smaller than the grains they were carrying. The noise which had aroused Jud had been made by their cutting off the dry leaves with which the baskets were lined, to use in lining their underground nest. Professor Ditson told them that nothing could stop an ant-army. Once on the march, they would not turn back for fire or water and would furiously attack anything that tried to check them. "A remarkably efficient insect," concluded the professor, "for it bites with one end and stings with the other."
"This is what I call a nice quiet night!" murmured Jud, as he went back to his hammock. "Sea-devils, snakes, lizards—and now it's ants. I wonder what next?"
"Next," however, was daylight, blazing with the startling suddenness of the tropics, where there is no dawn-light. With the light, the tumult of the night ceased, and in place of the insect din came a medley of bird-notes. When Jud opened his eyes Professor Ditson's hammock was empty, for the scientist usually got up long before daylight, and through the open door strutted a long-legged, wide-winged bird, nearly three feet tall, with a shimmering blue breast and throat. Without hesitating, she walked over to Jud's hammock and, spread her wings with a deep murmuring note, made a low bow.
"Good morning to you," responded Jud, much pleased with his visitor.
The bird bowed and murmured again and allowed him to pat her beautiful head as she bent forward. Then she went to the next hammock and the next and the next, until she had awakened all of the sleepers, whereupon, with deep bows and courtesies and murmurings, she sidled out of the room.
"Now, that," said Jud, as he rolled out of the hammock and began to look for his shoes, "is an alarm-clock worth having!"
Pinto, the Mundurucu, who appeared at this moment with a pail of spring water, told them that the bird was a tame female trumpeter which he had picked up as a queer, frightened little creature, all legs and neck, but which had become one of the best-loved of all of his many pets. Each morning the tame, beautiful bird would wander through the house, waking up every sleeper at sunrise. When Pinto took trips through the forest the bird always went with him, traveling on his back in a large-meshed fiber bag; and when he made camp it would parade around for a while, bowing and talking, and then fly up into the nearest tree, where it would spend the night. Tente, as it was named, was always gentle except when it met a dog. No matter how large or fierce the latter might be, Tente would fly at it, making a loud, rumbling noise, which always made the dog turn tail and run for its life.
As Pinto started to fill the pitchers, Will, the bird expert of the party, began to ask him about some of the songs which were sounding all around the house. One bird which squalled and mewed interested him.
"That bird chestnut cuckoo," said Pinto. "It have the soul of a cat."
And as Will listened he could well believe it. A little farther off, another bird called constantly, "Crispen, Crispen, Crispen."
"One time," narrated the Indian, "a girl and her little brother Crispen go walking in the woods. He very little boy and he wander away and get lost, and all day and all night and all next day she go through the woods calling, 'Crispen! Crispen! Crispen!' until at last she changed into a little bird. And still she flies through the woods and calls 'Crispen!'"
At this point, Jud finally found his missing shoes and started to put one on, but stopped at a shout from the Mundurucu.
"Shake it out!" warned Pinto. "No one ever puts on shoes in this country without shaking out."
Jud did as he was told. With the first shoe he drew a blank. Out of the second one, however, rattled down on the floor a centipede fully six inches long, which Pinto skillfully crushed with the heavy water-pitcher. Jud gasped and sank back into his hammock.
"Boys," he said solemnly, "I doubt if I last out this trip!"
