Gradually the motor-car firms came in, turning their body-building departments to plane and fuselage construction, which enabled them to turn out the complete planes engined and ready for the field.
Having reached Fifth Avenue, he paused to mop his perspiring brow when a long, low automobile, powerfully engined, that was creeping along behind, pulled up with a sudden jerk, and its driver, whose immense shoulders were clad in a very smart livery, pushed up the peak of his smart cap to run his fingers through his close-cropped hair, while his mild blue eyes grew very wide and round.
Again, while such a school machine as this is engined adequately, it is at the same time comparatively slow in flight, and has the advantage also that it will alight at slow speeds. In the air, too, it has a large measure of stability, and is not too rapid in its response to its controls.
Under convictions thus slowly recasting, the first big steam ships-of-war carried merely "auxiliary" engines; were in fact sailing vessels, of the types in use for over a century, into which machinery was introduced to meet occasional emergencies. In some cases, probably in many, ships already built as sailers were lengthened and engined.
This pioneer steamer was the Charlotte Dundas, which ran on the Forth and Clyde Canal in Scotland in 1801. Six years later Fulton's Clermont, engined by the British firm of Boulton and Watt, ran on the Hudson from New York to Albany. Two years later again the Accommodation, the first steamer in Canada, was launched at Montreal, and engined there as well.
On certain early-type biplanes, for instance, machines with large tail-planes, and engined as a rule by a motor which was giving less than its proper amount of power, it was most dangerous for a pilot if, on observing any signs of failing in his engine, he sought to fly on in the hope that the motor would "pick up" again, and continue its work.
According to official German sources of information the latest types of Zeppelins are engined by "noiseless" motors. There is nothing remarkable in this feature, since the modern motor-car virtually answers to this description, although in this instance quietness is obtained for the most part by recourse to the sleeve-valve engine.
