The limits of progress in this direction hadbeen reached. Meantime, alterations in the shape of the gas bagand the use of a mechanical propelling force hadbeen suggested. Very early in the history of aviation, the Due deChartres had commissioned the brothers Robert toconstruct a fish-shaped balloon, with which somesuccessful ascents were made. They could not becalled flights, since the oars with which this pioneerairship was provided proved utterly ineffectual. Agreat step forward was made by Giffardair^hi^ S m X^52 W^h his cigar-shaped airship driven by a three-horse-power steamengine weighing three quarters of a ton. Twentyyears after, Paul Haenlin built an airship in Vienna,much more nearly resembling the modern type, andfitted—momentous innovation—with a gas engine. Tissandiers dirigible followed ten years later with anelectrically-driven motor, and, in 1S84, two French. officers, Captains Renard and Krebs, designed LaFrance. This fine airship established some veryinteresting and important records. It was the firstaerial vessel in which the propeller was turned into a
