In this age of inventive wonders all men have come to believe that in some genius' brain sleeps the solution of the grand problem of aerial navigation-and along with that belief is the hope that that genius will reveal his miracle before they die, and likewise a dread that he will poke off somewhere and die himself before he finds out that he has such a wonder lying dormant in his brain. We all know the air can be navigated-therefore, hurry up your sails and bladders-satisfy us-let us have peace.
