As a farmer boy, young Cyrus McCormick began his day's work in the fields at five o'clock. In winter he went to the Old Field School. During his boyhood he would watch his father's experiments and disappointments. His first attempt in the same direction was the construction, at the age of fifteen, of a harvesting-cradle by which he was enabled to keep up with an able-bodied workman. His first patented invention (1831) was a plough which threw alternate furrows on either side, being thus either a right-hand or left-hand plough. This was superseded in 1833 by an improved plough, also by McCormick, called the self-sharpening plough, which did excellent work. His father having worked long and unsuccessfully at a mechanical reaper, it was natural that young McCormick's mind should turn over the same problem from time to time, and his father's failures did not deter him, although Robert McCormick had suffered so much in mind and pocket through the impracticability of his reaper that he warned his son against wasting more time and money upon the dream. One martyr to mechanical progress was enough for the McCormick family. But the possibility of making a machine do the hard, hot work of the harvest-field had a fascination for the young man, and the more he studied the discarded reaping-machine made by his father in 1816, the more firmly he became convinced that while the principle of that device was wrong, the work could be done. In those days the development of the country really depended upon some better, cheaper way of harvesting. The land was fertile, and there was practically no end of it. But labor was scarce.
