The mainmast carried a powerful rotascope, which was alone capable of supporting the airship.
The other masts carried four powerful wings of oiled silk and huge proportions. The shape and mechanism of these wings Frank had derived from the model of the butterfly, an insect noted for its airy and swift flight.
By means of various pulleys and sockets these wings were made to act as lightly and gracefully as the model.
This is a meager and incomplete description of the Dart.
The Scientific Society’s committee were overwhelmed with the wonderful mechanism and the simple practicability of the Dart.
“Mr. Reade, we are delighted,” said the spokesman, “and we feel sure of your success. If you do not fail you will surely put your name upon the topmost scroll of fame.”
“I shall hope to succeed,” replied Frank, modestly. “That is my aim.”
The committee took its departure.
Only two days more remained of preparation for the wonderful voyage from zone to zone.
The whole scientific world was agog. After the sailing of the Dart with their representative, Professor Gaston, aboard, they waited with deepest interest for news from the party. They were destined to wait many weeks.
