"What's the use of learning to a miner?" exclaimed Simon with a gruff laugh. "However, you must have your way, Mary, and I don't mind paying for his schooling, though, look ye, if times get bad, he'll have to earn his bread like the rest of us." Mrs Gilbart thanked her uncle, hoping that the evil day was put off for a long time. Little Mark went to school, and being fond of his books, made rapid progress in reading and writing. He thus soon possessed himself of the key of knowledge. Little Mary was also sent to a girls' school, and being bright and intelligent, soon became a favourite pupil of the mistress. At length Mrs Hayes fell ill, and her niece's time was so fully occupied in attending on her, that she could gain nothing by her work. Then there was the doctor to pay. Simon also was laid up for some weeks from a severe bruise by a fall of coal. "I can't stand this no longer, niece," he said one day. "The next time I go down the pit I must take Mark with me." Mrs Gilbart begged hard that her boy might remain above ground. She would take him from school and try to get employment for him on a farm. Simon was obdurate; if she would not agree to his wishes she might leave his house. Her fears were all nonsense, the boy would do well enough in the pit, he would get tenpence a-day as a trapper--on a farm he couldn't get twopence. Without telling her what he was about to do, the first morning he returned to work he took Mark by the arm and led him along to the pit's mouth. He had brought a flannel suit. He made the boy put it on. "Now, Mark, we are going into the pit, and you'll do what I tell you when we get down," he said, as if it was a matter of course. "I've arranged with the manager to take you on from to-day as a trapper. Though you may not like it at first, you'll soon get accustomed to the work, and so let's have no nonsense. Here's the corve all ready to go down--come along." CHAPTER TWO. LEARNING TO WATCH. Simon, taking Mark by the hand, stepped on to an iron frame-work or cage, suspended over the pit's mouth. "Take hold of this bar and don't move as you value your life, boy," he said. Mark obeyed. Several other men and two boys stepped on to the cage, it began to descend. Though little Mark had been hearing of mines all his life, and felt no especial unwillingness, yet all seemed strange about him. It appeared to him by the dim light of the lamps which his uncle and the other men held in their hands, that the shafts were rushing upwards at a fearful rate, while the light of day, which he could still see above him, grew gradually less and less. A giddiness overtook him. He might have fallen, had not his uncle still held him by the shoulder. How long he had been descending he could not tell, when he found the cage come to a stand-still, and that he was down beneath the surface of the earth, a thousand feet or more.
