In 1815 the bicycle was first brought into England from France, consisting of two clumsy wooden wheels joined together by a wooden bar, astride which the rider sat and propelled himself by striking the ground with first one foot then the other. No real progre was apparent in the bicycle for the next fifty years, until in 1869 M. Michaux, of Paris, conceived the idea of making the driving-wheel much larger than the other. Shortly after M. Magee, also of Paris, developed the manufacture of the parts in steel and iron. From that time progre was more rapid. At about the same time, it is some Ordinary Bicycle, 1879. times claimed in 1865, Pierre Lallemont constructed a road worthy bicycle, at Ansonia, Conn. But American bicycling dates from ten years later, when Col. Pope of Boston and Harrington of England made and rode a bicycle of modern construction. The high-wheel soon gave way to the safety, or The line of latest development has been in the tires, the original metal tire being replaced, first by solid rubber and later by pneumatic tires, rubber tubes filled with air. The rims also have progre ed in the point of increased lightne from heavy metal to lighter metals and finally wood. The old high wheel weighed 50 lbs., the modern safety is often under 25, and racing wheels as low as 15 lbs. The increase of the use of bicycles in U. S. is shown by the fact that in 1885 there were 6 manufactories, with an output of 11,000 wheels; in 1890, 17, producing 40,000; while in 1895 there are 126, with a probable output of 500,000 machines. This will undoubtedly tend to develop better roads throughout the country. The speed attained is something remarkable, as the following records show up to 1895. The "Ordinary," Mile Records: W. W.
