In eleven years they had eleven children. There was both joy and sorrow with those children. For seven years, the eldest, little Polly, was nothing but joy to her parents. She was the prettiest little girl they had ever seen; and the neighbors thought so too. She was bright and merry, perfectly obedient, very clever, and so handy that she was a helpful little maid to her mother. When three infants died, one after another, her father found comfort in taking this child on his knees in the evenings, and getting her to prattle to him. Her clear little merry voice came easily to his ear, when he could not hear older people without difficulty. The next child, Tom, was a blessing in his way: he was a strong little fellow of six; and he went out with Banks to the field, and really did some useful work--frightening the birds, leading the horses, picking sticks, weeding, running errands, and so on. But the charm at home was little Polly. When Polly was seven, however, a sad accident happened. She was taking care of the little ones before the door, during her mother's confinement, and one of the boys struck her on the top of the head with a saucepan. She fell, and when she was taken up she looked so strangely that the doctor was consulted about her. After watching her for some weeks he said he feared there was some injury to the brain. Banks has had many troubles in life, but none has been sorer than that of seeing the change that came over this child. It was not the loss of her beauty that made his heart ache when he looked in her face: it was the staring, uneasy expression of countenance which made him turn his eyes away in pain of heart. She grew jealous and suspicious; and, though no mood of mind remained many minutes, this was a sad contrast with the open sweetness of temper that they were never more to see. She did as she was bid; she went on learning to cook and to sew, and she could clean the house; but she never remembered from one minute to another what she was to do, and was always asking questions about things that she had known all her life. Her uncle (her mother's brother), who was well off in the world, and had no children, took her home, saying that change and going to school would make all the difference in her. But she had no memory, and could learn nothing, while she lost the mechanical things she could do at home. So, after a patient trial of three years, her uncle brought her home, and took, in her stead, the bright little Susan, now four years old. Polly never got better. After a time, fits of languor came on occasionally, and her mother could not get her out of bed; and now she sometimes lies for many days together, as in a swoon, looking like one dying, but always reviving again, though declining on the whole; so that it is thought it can not now go on very long.
