Then close at hand in a neighborhood tree-top sounded a beautiful contralto frog-note slowly repeated. "Gul, gul, gul, gul, guggle, gul, guggle," it throbbed. The slow, sweet call gave the boy a sense of companionship, and he fell asleep with the music of it still sounding in his ears.
Toward midnight he woke with a vague sense of uneasiness. It was as if some hidden subconsciousness of danger had sounded an alarm note within his nerve centers and awakened him. Something seemed to be moving and whispering outside of the screened alcove. Then a body struck the screen of mosquito-netting, and he heard the rotten fiber rip. Another second, and his little room was filled with moving, flitting, invisible shapes. Great wings fanned the air just above his face. There was the faint reek of hot, furry bodies passing back and forth and all around him. For a moment Will lay thinking that he was in a nightmare, for he had that strange sense of horror which paralyzes one's muscles during a bad dream so that movement is impossible. At last, by a sudden effort, he stretched out his hand and struck a match from a box which stood on a stand beside his hammock. At the quick spurt of flame through the dark, from all parts of the little room came tiny, shrill screeches, and the air around him was black with whirling, darting shapes. Suddenly into the little circle of light from the match swept the horrible figure of a giant bat, whose leathern wings had a spread of nearly two and a half feet, and whose horrible face hovered and hung close to his own. Never had the boy believed that any created thing could be so grotesquely hideous. The face that peered into his own was flanked on each side by an enormous leathery ear. From the tip of the hairy muzzle grew a spearlike spike, and the grinning mouth was filled with rows of irregular, tiny, gleaming sharp teeth, gritting and clicking against each other. Deep-set little green eyes, which glistened and gleamed like glass, glared into Will's face. Before he could move, a great cloud of flying bats, large and small, settled down upon him. Some of them were small gray vampire-bats with white markings, others were the great fruit-eating bats, and there were still others dark-red, tawny-brown, and fox-yellow. Whirling and wheeling around the little point of flame, they dashed it out, and crawled all over the boy until he felt stifled and smothered with the heat of their clinging bodies.
