A careful study of the pre-McCormick Reapers reveals one fault common to all,--they were made by theorists, to cut ideal grain in ideal fields. Some of them, if grain always grew straight and was perfectly willing to be cut, might have been fairly useful. They assuredly might have succeeded if grain grew in a parlor. But to cut actual grain in actual fields was another matter, and quite beyond their power. None of them, apparently, knew the fundamental difference between a Reaper and a mower. They did not observe that grain is easy to cut but hard to handle, while grass is hard to cut and easy to handle; and they persisted in the assumption that grain could be reaped by a mower. [Illustration: INTERIOR OF BLACKSMITH SHOP IN WHICH C. H. McCORMICK BUILT HIS FIRST REAPER] These inventors who failed, but who doubtless blazed the way by their failures to the final success of McCormick, were not, as he was, a practical farmer on rough and hilly ground. One was a clergyman, who devised a six-wheel chariot, with many pairs of scissors, and which was to be pushed by horses and steered by a rudder that in rough ground would jerk a man's arm out of joint. A second of these inventors was a sailor, who experimented with a few stalks of straight grain stuck in gimlet holes in his workshop floor. A third was an actor, who had built a Reaper that would cut artificial grain on the stage. A fourth was a school-teacher, a fifth a machinist, and so on. In no instance can we find that any one of these pre-McCormick inventors was a farmer, who therefore knew what practical difficulties had to be overcome. The farmers, on the other hand, thought first of these difficulties and scoffed at the parlor inventors. The editor of the "Farmer's Register" spoke the opinion of most farmers of that time when he said that "an insurmountable difficulty will sometimes be found to the use of reaping-machines in the state of the growing crops, which may be twisted and laid flat in every possible direction. A whole crop may be ravelled and beaten down by high winds and heavy rains in a single day." One of the basic reasons, therefore, for the success of Cyrus McCormick was the fact that he was not a parlor inventor. He was primarily a farmer. He knew what wheat was and how it grew. And his first aim in making a reaper was not to produce a mechanical curiosity, nor to derive a fortune from the sale of his patent, but to cut the grain on his father's farm. So far as the pre-McCormick inventors are concerned, the whole truth about them seems to be that a few invented fractional mowers or reapers that were fairly good as far as they went, and that most of them invented nothing that became of any lasting value. Nine-tenths of them were pathfinders in the sense that they showed what ought _not_ to be done.
