Once when Eli's father was gone from home for several days, the boy was very busy all the while in the little shop. When Mr. Whitney came back he asked his housekeeper, "What has Eli been doing?" "Oh," she replied, "he has been making a fiddle." His father shook his head, and said that he was afraid Eli would never get on much in the world. But Eli's fiddle, though it was rough-looking, was well made. It had music in it, and the neighbors liked to hear it: somehow it seemed to say through all the tunes played on it, "_Whatever is worth doing, is worth doing well._" 177. Eli Whitney begins making nails; he goes to college.--When Eli was fifteen, he began making nails. We have machines to-day which will make more than a hundred nails a minute; but Eli made his, one by one, by pounding them out of a long, slender bar of red-hot iron. Whitney's hand-made nails were not handsome, but they were strong and tough, and as the Revolutionary War was then going on, he could sell all he could make. After the war was over the demand for nails was not so good. Then Whitney threw down his hammer, and said, "I am going to college." He had no money; but he worked his way through Yale College, partly by teaching and partly by doing little jobs with his tools. A carpenter who saw him at work one day, noticed how neatly and skilfully he used his tools, and said, "There was one good mechanic spoiled when you went to college." 178. Whitney goes to Georgia; he stops with Mrs. General Greene; the embroidery frame.--When the young man had completed his course of study he went to Georgia to teach in a gentleman's family. On the way to Savannah he became acquainted with Mrs. Greene, the widow of the famous General Greene[4] of Rhode Island. General Greene had done such excellent fighting in the south during the Revolution that, after the war was over, the state of Georgia gave him a large piece of land near Savannah. Mrs. Greene invited young Whitney to her house; as he had been disappointed in getting the place to teach, he was very glad to accept her kind invitation. While he was there he made her an embroidery frame. It was much better than the old one that she had been using, and she thought the maker of it was wonderfully skilful. [Footnote 4: General Greene: see paragraph 140.] 179. A talk about raising cotton, and about cotton seeds.--Not long after this, a number of cotton-planters were at Mrs. Greene's house. In speaking about raising cotton they said that the man who could invent a machine for stripping off the cotton seeds from the plant would make his fortune. For what is called raw cotton or cotton wool, as it grows in the field, has a great number of little green seeds clinging to it. Before the cotton wool can be spun into thread and woven into cloth, those seeds must be pulled off. [Illustration: POD OF THE COTTON PLANT WHEN RIPE AND OPEN.
