One of the entries in the sack race seeks to beat all comers by the use of mattress springs concealed in his sack. When the race commences, people hold their breath as they watch him cover the ground after the manner of a bouncing ball. So remarkable is his flight over the course that he is almost regarded as another budding Curtis or Bleriot, with some new found power for propelling humanity through space. But his would-be glory is short-lived, for the trick is discovered and the momentary champion is strongly denounced. Then, to the astonishment of everybody the sack from which the man has emerged becomes animated and commences a hopping excursion on its own accord around the course. A shot from a gun, however, lets the cat out of the bag, as it were, for the springs fly up into the air and expose the whole subterfuge.
