In 1855, at a competitive trial of reapers near Paris, three machines were entered. The American machine cut an acre of oats in twenty-two minutes, the English machine in sixty-six minutes, and the Algerian in seventy-two. In 1863, at the great International Exposition at Hamburg, the McCormick reaper again took the grand prize. While in Paris in 1878 Mr. McCormick was elected a member of the French Academy of Sciences as “having done more for the cause of agriculture than any living man.” Mr. McCormick continued to the end of his days, in 1884, to devote his entire energies to the development of the reaper, and well deserved the princely fortune that resulted from his indefatigable labors, a good portion of which fortune he spent during his life in the cause of education and acts of philanthropy. The inventory of his estate, filed in the Probate Court of Cook County, Ill., showed $10,000,000 as the reward of his genius and industry, and is an object lesson of the reward of merit for the ambitious youth of the Twentieth Century. [Illustration: FIG. 153.--THE MARSH HARVESTER OF 1858.] [Illustration: FIG. 154.--THE CHAMPION REAPER.] In the development of the reaper one of the first deficiencies to be supplied was automatic mechanism for taking the grain from the platform. In November, 1848, F. S. Pease took out patent No. 5,925 for a rake whose teeth projected up through slots in the platform, and moved back and forth to deposit the grain upon the ground. On June 19, 1849, J. J. & H. F. Mann took out patent No. 6,540 on a machine employing the principle of an endless band for carrying the cut grain to the side of the machine, where it passed up an inclined plane and accumulated in a receptacle to form a gavel, which was clumped upon the ground. This machine is shown in Fig. 152. On July 8, 1851, W. H. Seymour took out patent No. 8,212 for a self-raker, and this machine marks the beginning of the era of self-raking reapers, which for a quarter of a century in various modifications continued to be used, until displaced by subsequent improvements in binding devices. In 1853 the Sylla and Adams machine was brought out, the patents for which were bought by the Aultmans, and the Aultman and Miller, or “Buckeye” harvester, was manufactured thereunder. The general form of the modern harvester has followed along the lines of the Mann machine of 1849. The development began by replacing the gavel receptacle on the right of that machine (Fig. 152) with a platform on which stood men who rode on the machine as they bound the grain. An early and important example of a harvester of this class is given in the Marsh machine, patented August 15, 1858, No. 21,207, and shown in Fig. 153. To this type of machine the self-binding devices were subsequently applied, but before they materialized many other improvements in self-rakers were made and applied, among which may be mentioned the combined rake and reel of Owen Dorsey, of Maryland
