Five o'clock
`` The more I turned the subject over in my mind the stronger I became impressed with the idea that desperate cases necessitate strenuous remedies . The heat of the afternoon became oppressive , and the haze had become a thick fog over the water . Occasionally it would lift slightly and then settle down more dense than before . Five o'clock came , and still no steamer . About ten minutes later we heard a sound that nearly knocked me out . It was the steamer with the other fellow 's show . We heard the blow , but could not get a glimpse of the blowpipe .
