And ten minutes later the plane loomed up out of the mist, queerly ungainly on the surface of the water. Its motors roared impatiently as if held in leash. It swung clumsily about, heading off out of sight in the fog to turn. It came back, sliding along the top of the water with its wing-tip floats leaving alternate streaks of white foam behind them. A man stood up in its after cockpit. Bell crowded to the rail. The man--goggled and masked--held up a package as if to fling it on board. Bell watched grimly. But he saw that the pilot checked himself and looked up at the upper deck. Bell craned his neck. The wireless operator was waving wildly to the seaplane. He writhed his hands, and held his hand to his head is if blowing out his brains, and waved the plane away, frantically. The pilot of the plane sat down. A moment later its motors roared more thunderously. It is not safe to alight on either land or water when fog hangs low, but there is little danger in taking off. The seaplane shot away into the mist, its motors bellowing. The sound of its going changed subtly. It seemed to rise, and grow more distant.... It died away. Bell halted at the top of the companion-ladder and saw the wireless operator, with a crooked, nervous grin upon his face. CHAPTER III Bell saw what he was looking for, out in the throng of traffic that filled the Avenida do Acre, in Rio. He'd seen it over the heads of the crowd, which was undersized, as most Brazilian crowds are, and he managed to get through the perpetual jam on the mosaic sidewalk and reach the curb. He stood there and regarded the vehicles filling the broad avenue, wearing exactly the indifferent, half-amused air of a tourist with no place in particular to go and a great deal of time in which to go there. Taxis chuffed past, disputing right of way with private cars which were engaged in more disputes with other cars, all in the rather extraordinary bad temper and contentiousness which comes to the Latin-American when he takes the wheel of an automobile. As if coming to an unimportant decision, Bell raised his hand to an approaching cab. It had two men on the chauffeur's seat. Of course. All taxis in Rio carry two men in front. One drives, and the other lights his cigarettes, makes witty comments upon passing ladies, and helps in collecting the fares from recalcitrant passengers. The extra man is called the "secretary," and he assists materially in giving an impression of haughty pride. The taxi ground to the curb. The secretary reached behind him indifferently and opened the door. Bell did not glance at him. He stepped inside and settled down languidly. "The Beira Mar," he said listlessly.
