ELI WHITNEY began to make things when he was a small boy. He was called a genius because he was so ingenious. But he was not satisfied with doing things with his hands. He had a strong desire to make the most of his mind. So he went to Yale College and studied philosophy. One day the professor said he could not show a certain method to the class because the machine he kept for the purpose was broken. He could not teach that lesson until a new apparatus could be brought from England or France. But the ingenious student looked at the machine, and said, “Let me fix it.” The professor thought it could do no harm to let him try. Eli made the fine machine work just as well as it did when it was new.
One of the bravest officers in the Revolutionary War, which ended a few years before this time, was General Nathanael Greene. After the war General Greene lived on a beautiful estate near Savannah, Georgia, and died there. When young Whitney finished his college course, he was engaged to teach a school in Savannah; but when he went down there he found that the school was not what he expected. So he acted as tutor in the family of General Greene’s widow.
While he was tutor, Whitney made playthings for the children, and fixed many handy things for Mrs. Greene to use about the house. She told him he ought to make a machine that would take the seeds out of the bolls, or fluffy heads, of the cotton plant. Great machines had been contrived for spinning and weaving cotton, but it took a man or a woman all day to pick the seeds out of a pound of cotton wool.
Eli Whitney went to work to make something that would do what in those days seemed impossible. He not only had to invent a cotton-gin, as the new machine was called, but he was obliged to make tools for making the machine itself, and even tools for making the other tools. But within a short time he had invented and built a machine which worked quite well. Still he was not satisfied. He locked himself up in a room and worked day and night until he had built a perfect cotton-gin which would work very fast and would clear out all the fine cotton seeds. This was in 1793, while Washington was President, and Philadelphia was the capital of the United States.
Whitney would not let any one but Mrs. Greene and a friend named Miller see the model, or pattern, of his cotton-gin until he could take out a patent for it. But before he could get money enough to have his gin patented, someone broke into his little shop and carried off his precious model.
