From the age of eleven to seventeen, according to his own story as told in his "Personal Memoirs," he ploughed the soil, cultivated the growing corn and potatoes, sawed fire-wood for his father's store, and did any other work that would naturally fall to the lot of a farmer's boy. He had his recreations, also, including fishing, swimming in the creek not far from his home, skating in winter, and driving about the country winter and summer. Young Grant liked horses, and early became a skilful rider. Lincoln told a story of him which indicates not only his expert horsemanship, but his "bull-dog grit" as well. One day when he was at a circus the manager offered a silver dollar to anybody who could ride a certain mule around the ring. Several persons, one after another, mounted the animal only to be thrown over its head. Young Ulysses was among those who offered to ride, but like the others he was unsuccessful. Then pulling off his coat, he got on the animal again. Putting his legs firmly around the mule's body, and seizing him by the tail, Ulysses rode triumphantly around the ring, amid the cheers of the expectant crowd. Although he cared little for study, his father wished to give him all the advantages of a good education, and secured for him an appointment at West Point. This was indeed a rare opportunity for thorough training in scholarship, but Ulysses was rather indifferent to it. He had a special aptitude for mathematics, and became an expert horseman, but with these exceptions, he took little interest in the training received at this famous military school, his rank being only twenty-first in a class of thirty-nine. After graduation he wished to leave the army and become an instructor in mathematics at West Point. But as the Mexican War broke out about that time he entered active service. Soon he gave striking evidence of that fearless bravery for which he was to become so noted on the battle-fields of the Civil War. It fell to his lot to deliver a message which necessitated a dangerous ride. He says of it: "Before starting I adjusted myself on the side of my horse farthest from the enemy, and with only one foot holding to the cantle of the saddle and an arm over the neck of the horse exposed, I started at full run. It was only at the street crossings that my horse was under fire, but there I crossed at such a flying rate that generally I was past and under cover of the next block of houses before the enemy fired. I got out safely without a scratch." Shortly after the close of the war Grant was married. Six years later he resigned from the army and went with his family to live on a farm near St. Louis. Although he worked hard, he found it up-hill work to support his family, and was eventually compelled by bad health to give up farming. He next tried the real estate business, but without success. At last, his father offered him a place in his leather and hardware store, where Grant worked as clerk until the outbreak of the Civil War.
