| | Novel Aerial Sailing Craft |
 | | This aerial sailing craft, with its 26 pairs of fixed wings, made of large feathers, glued by their quills into light wood slats, measured in spread 20 feet, height 12 feet, and length, fore and aft, 8 feet, and the craft weighed complete on wheels, as illustrated, 55 pounds. |
 | | The normal position of the craft and its center of gravity imparted to all the wings a lifting angle of 1 to 1O to guard against its pitching forward. |
 | | Irish's aerial sailing craft, which greatly depends on the force of gravity for progressive motion, sails on the air by vertically inclined tacks instead of horizontally inclined tacks as a sailing ship driven on the water by the wind. |
