So about the year 1800 inventors in Europe and in America took up the task of inventing a new kind of reaper. The first attempts were made in England where population was increasing very fast and where large quantities of grain were needed to feed the people. The first hints for a reaper were from a machine which was used in Gaul nearly 2,000 years ago. Pliny, who described for us a wonderful plow used in his time (p. 77), also describes this ancient reaper of the Gauls. It consisted of a large hollow frame mounted on two wheels (Fig. 7). At the front of the frame there was a set of teeth which caught the heads of grain and tore them off. The heads were raked into the box by an attendant. The machine was pushed along by an ox. This kind of machine was doubtless used in Europe for a while but it was not a success. It passed out of use and for many centuries it was entirely forgotten. Still, the first English reaping machines were made after the plan of this interesting old reaper of ancient Gaul. [Illustration: FIG. 8.--OGLE'S REAPER, 1822.] The most remarkable of the early reapers was one invented by Henry Ogle, a schoolmaster of Remington, England. In 1822 Ogle constructed a model for a reaper which was quite different from any that had appeared before and which bore a close resemblance to the improved reapers of a later date. In Ogle's reaper (Fig. 8) the horse walked ahead beside the standing grain, just as it does now, and the cutting apparatus was at the right, just as it is now. The cutter consisted of a frame at the front of which was a bar of iron armed with a row of teeth projecting forward. Directly under the teeth lay a long straight edged knife which was moved to and fro by means of a crank and which cut the grain as it came between the teeth. A reel pushed the grain toward the knife and there was a platform upon which the grain when cut might fall. Ogle's machine did not meet with much success yet it holds a very high place in the history of reaping machines, for it had nearly all the parts of a modern reaper. [Illustration: FIG. 9.--THE FIRST MCCORMICK REAPER.] English inventors did much to prepare the way for a good reaping machine but the first really successful reaper, the first reaper that actually reaped, was made in the United States. In the summer of 1831, Cyrus McCormick, a young blacksmith living in the Shenandoah Valley in Virginia, made a trial of a reaper which he and his father had invented--how much they had learned from Ogle we do not know--and the trial was successful (Fig. 9). With two horses he cut six acres of oats in an afternoon. "Such a thing," says Mr. Casson in his life of McCormick, "at the time was incredible. It was equal to the work of six laborers with scythes or twenty-four peasants with sickles. It was as marvelous as though a man had walked down the street carrying a dray horse on his back."
