At twenty-one came his first opportunity; came, as it often comes, through a friend. Mr. John McNairy was appointed a judge of the Superior Court of the Western District of North Carolina (Tennessee), and young Jackson, his friend, public prosecutor of the same district. He moved to Nashville in 1788, to begin his difficult work. He was obliged to ride on horseback over the mountains and through the wilderness, often among hostile Indians, his life almost constantly in danger. Once, while travelling with a party of emigrants, when all slept save the sentinels, he sat against a tree, smoking his corn-cob pipe and keeping an eager watch. Soon he heard the notes of what seemed to be various owls! He quietly roused the whole party and moved them on. An hour later, a company of hunters lay down by the fires which Jackson had left, and before daylight all save one man were killed by the Indians. Sometimes the young lawyer slept for twenty successive nights in the wilderness. This was no life of ease and luxury. At Nashville he found lodgings in the house of the widow of Colonel John Donelson, a brave pioneer from Virginia, who had been killed by the Indians. And here Jackson met the woman who was to prove his good angel as long as she lived. With Mrs. Donelson lived her dark-haired and dark-eyed daughter Rachel, married to Lewis Robards from Kentucky. Vivacious, kindly, and sympathetic, Rachel had been the idol of her father, and probably would have been of her husband had it not been for his jealous disposition. He became angry at Jackson, as he had been at others, and made her life so unhappy that she separated from him and went to friends in Natchez, with the approval of her mother, and the entire confidence and respect of her husband's relatives. After a divorce in 1791, Jackson married her, when they were each twenty-four years old. History does not record a happier marriage. To the last, she lived for him alone, but not more fully than he lived for her. With the world he was thought to be domineering and harsh, and was often profane; but with her he was patient, gentle, and deferential. When he won renown, she was happy for his sake, but she did not care for it for herself. Her kindness of heart took her among the sick and the unfortunate, and everywhere she was a welcome comforter. She lived outside of self, and found her reward in the homage of her husband and her friends.
