Abraham Lincoln was now twenty-one, and his father had been a hard master, taking all his wages. He therefore, after doing his best to settle the family in their new home, went forth to work for himself among the farmers. One George Cluse, who worked with Abraham during the first year in Illinois, says that at that time he was “the roughest-looking person he ever saw: he was tall, angular, and ungainly, and wore trousers of flax and tow, cut tight at the ankle and out at the knees. He was very poor, and made a bargain with Mrs. Nancy Miller to split 400 rails for every yard of brown jean, dyed with walnut bark, that would be required to make him a pair of trousers.” Thomas Lincoln found, in less than a year, that his new home was the most unhealthy of all he had tried. So he went Westward again, moving to three new places until he settled at Goose Nest Prairie, in Coles County, where he died at the age of seventy-three, “as usual, in debt.” From the time of his death, and as he advanced in prosperity, Abraham aided his stepmother in many ways besides sending her money. It was at Decatur that he made his first public speech, standing on a keg. It was on the navigation of the Sangamon River, and was delivered extemporaneously in reply to one by a candidate for the Legislature, named Posey. During the winter of 1831, a trader, named Denton Offutt, proposed to John Hanks, Abraham Lincoln, and John D. Johnston, his stepmother’s son, to take a flat-boat to New Orleans. The wages offered were very high--fifty cents a day to each man, and sixty dollars to be divided among them at the end of the trip. After some delay, the boat, loaded with corn, pigs, and pork, sailed, but just below New Salem, on the Sangamon, it stuck on a dam, but was saved by the great ingenuity of Lincoln, who invented a novel apparatus for getting it over. This seems to have turned his mind to the subject of overcoming such difficulties of navigation, and in 1849 he obtained a patent for “an improved method of lifting vessels over shoals.” The design is a bellows attached to each side of the hull, below the water-line, to be pumped full of air when it is desired to lift the craft over a shoal. The model, which is eighteen or twenty inches long, and which is now in the Patent Office at Washington, appears to have been cut with a knife from a shingle and a cigar-box.[12] John Hanks, apparently a most trustworthy and excellent man, declared that it was during this trip, while at New Orleans, Lincoln first saw negroes chained, maltreated, and whipped. It made a deep impression on his humane mind, and, years after, he often declared that witnessing this cruelty first induced him to think slavery wrong. At New Orleans the flat-boat discharged its cargo, and was sold for its timber. Lincoln returned on a steamboat to St. Louis, and thence walked home. He had hardly returned, before he received a challenge from a famous wrestler, named Daniel Needham. There was a
