At his scream, Professor Ditson rushed in with a flash-light, followed by Pinto, Hen, and Joe, while Jud slept serenely through the whole tumult. They found Will dripping with blood from a dozen little punctures made by the sharp teeth of the bats, and almost exhausted from fright and the loss of blood. Then came pandemonium. Seizing sticks, brooms, machetes, anything that came to hand, while Will sank back into his hammock, the others attacked the bats. Lighted by the flash of Professor Ditson's electric light, they drove the squeaking, shrieking cloud of dark figures back and forth through the little room until the last one had escaped through the torn netting or was lying dead on the floor.

Twenty-seven bats altogether were piled in a heap when the fight was over.


[CHAPTER IV]

Death River

At last their first week in this new world of beauty and mystery came to an end. At Belem they boarded a well-appointed steamer and embarked for the thousand-mile voyage to Manaos, which is only six degrees from the equator and one of the hottest cities of the world. There followed another week of a life that was strange and new to the travelers from Cornwall. There were silent, steaming days when the earth seemed to swoon beneath the glare of the lurid sun, and only at night would a breath of air cross the water, which gleamed like a silver burning-glass. For their very lives' sake, white men and Indians alike had learned to keep as quiet and cool as possible during those fiery hours. Only Hen, coming from a race that since the birth of time had lived close to the equator, moved about with a cheerfulness which no amount of heat or humidity could lessen. At night, when the fatal sun had reluctantly disappeared in a mass of pink and violet clouds, the life-bringing breeze would blow in fresh and salt from the far-away sea, and all living creatures would revive. The boys soon learned that, in the mid-heat of a tropical summer, the night was the appointed time for play and work, and they slept during the day as much as possible in shaded, airy hammocks.

One evening, after an unusually trying day, the night wind sprang up even before the sun had set. Here and there, across the surface of the river, flashed snow-white swallows with dark wings. As the fire-gold of the sun touched the horizon, the silver circle of the full moon showed in the east, and for a moment the two great lights faced each other. Then the sun slipped behind the rim of the world, and the moon rose higher and higher, while the Indian crew struck up a wailing chant full of endless verses, with a strange minor cadence like the folk-songs of the Southern negro. Hen Pine translated the words of some of them, and crooned the wailing melody:

"The moon is rising,
Mother, Mother,
The seven stars are weeping,
Mother, Mother,
To find themselves forsaken,
Mother, Mother."

Down the echoing channels, through the endless gloomy forests, the cadence of the song rose and fell.

Suddenly, in the still moonlight from the river-bank came a single low note of ethereal beauty and unutterable sorrow. Slowly it rose and swelled, keeping its heartbreaking quality and exquisite beauty. At the sound the men stopped singing, and it seemed as if an angel were sobbing in the stillness. On and on the song went, running through eight lonely, lovely notes which rose and swelled until there seemed to be nothing in the world except that beautiful voice, finally ending in a sob which brought the tears to Will's eyes. Then out into the moonlight flitted the singer, a quiet-colored little brown-and-gray bird, the celebrated solitaire, the sweetest, saddest singer of the Brazilian forest.
