Of all the varieties of difficulties that confronted Cyrus H. McCormick during his strenuous life, the most baffling and disconcerting difficulty was when his Reaper began to grow. For fifteen years--from 1845 to 1860--it had remained unchanged except that seats had been added for the raker and the driver. It did no more than cut the grain and leave it on the ground in loose bundles. It had abolished the sickler and the cradler; but there yet remained the raker and the binder. Might it not be possible, thought the restless American brain, to abolish these also and leave no one but the driver? This at once became a most popular and fascinating problem for inventors. There was by this time everything to gain and nothing to lose by improving the Reaper. There was no opposition and no ridicule. To cut grain by horse-power had become, of course, the only proper way of cutting it. As many as 20,000 Reapers of all kinds were made in 1860; and McCormick's factory had grown to be the pride of Chicago. It was 90 by 150 feet in size, two stories high, and gave work to about a hundred and twenty men. As early as 1852 a fantastic self-rake Reaper had been invented by a mechanical genius named Jearum Atkins. This man was a bed-ridden cripple, who, to while away the tiresome hours of his confinement, bought a McCormick Reaper, had it placed outside his window, and actually devised an attachment to it which automatically raked off the cut grain in bundles. It was a grotesque contrivance. The farmers nicknamed it the "Iron Man." It consisted of an upright post, with two revolving iron arms. These arms whirled stiffly around, windmill fashion, and scraped the grain from the platform to the ground. An amusing anecdote of this machine was told by Henry Wallace, known to all farmers of the Middle West as the founder of _Wallace's Farmer_. "The first Reaper that my father bought," said Mr. Wallace, "was a McCormick machine that had an 'Iron Man' on it. The first day that it was driven into the grain it made such a clatter that the horses ran away. It was certainly a terrifying sight as it rattled through the wheat, with its long, rake-fingered arms flying and hurling the cut grain in the wildest disorder. It was as good as a chariot race in a circus to the crowd of farmers, who had come to see how the new machine would operate. The next day my father tried again. There had been rain during the night, and the heavy machine stuck fast in the mud. It had cost $300, but my father took the 'Iron Man' off, and during the remainder of that harvest we raked off the grain by hand."
