In this picture we see the possibility of aerial navigation on a very simple scale. A messenger boy starts out on a bicycle with a load of paper boxes on his back. He rides along for some time without any eventful thing happening, until he collides with a delivery cart, upsetting everything all over the street, and causing no end of excitement. He gathers up his fragments and is soon on his way again. Some of the boxes lose their covers and when the wind gets a sweep at them they serve an as aeroplane and away he goes up in the air, still seated on the bicycle. We see him traveling at a great rate of speed over the house tops, and his feet twirling the wheels and keeping up the velocity. Finally he drops on a roof and knocks over the chimney on the heads of the pursuing crowd. He climbs down a pole to the street and is carried like a wonderful hero on the shoulders of one of the spectators, who appreciates his share in the advancement of aerial navigation.
