Bell laughed, though it sounded more like a bark, as Ribiera flung himself to the ground and screamed hoarsely when the plane seemed about to pounce upon him. The shrill timbre of the shriek cut through the roaring of the motors, even through the thick padding of the big plane's cabin walls that reduced that roaring to a not intolerable growl.

But the plane passed ten feet or more above his head. It rose, and climbed steeply, and passed again above the now buzzing, agitated hangars, and climbed above the hills behind the flying field as some men went running and others moved by swifter means toward the shaken, nerve-racked Ribiera, on whose lips were flecks of foam.

Bell looked far below and far behind him. The incredible greenness of tropic verdure, of the jungle which rings Rio all about. The many glitterings of sunlight upon glass, and upon the polished domes of sundry public buildings, and the multitudinous shimmerings of the tropic sun upon the bay. The deep dark shadow of the banking clouds drew a sharp line across the earth, and deep in that shadow lay the flying field, growing small and distant as the plane flew on. But specks raced across the wide expanse. In a peculiar, irrational fashion those specks darted toward a nearly invisible speck, and encountered other specks darting away from that nearly invisible speck, and gradually all the specks were turned about and racing for the angular, toy-block squares which were the hangars of the aeroplanes of the city of Rio de Janeiro.

Little white things appeared from those hangars--planes being thrust out into the open air while motes of men raced agitatedly about them. One of them was suddenly in motion. It moved slowly and clumsily across the ground, and then abruptly moved more swiftly. It seemed to float upward and to swing about in mid-air. It came floating toward the amphibian, though apparently nearly stationary against the sky. Another moved jerkily, and another....

Just before the big plane dived into the wide white wall of falling water, the air behind it seemed to swarm with aircraft.

In the cabin of the amphibian, of course, the bellowing of the motors outside was muffled to a certain degree. Paula clung to the seats and moved awkwardly up to the place beside Bell. She had just managed to seat herself when the falling sheet of water obliterated all the world.
