We must proceed more rapidly than heretofore with Mark Gilbart's history. He did his duty as a trapper, never falling asleep, and always opening and shutting the trap at the proper moment. The rolley boys never complained of him, and as he was invariably in good humour, and stood their chaffing, he became a favourite. Often he had to go into the pit before daylight, and remain until ten o'clock at night with one candle to light him on his way to his trap, and another with which to return. As he always told his mother that he was happy, and he appeared to be in tolerable health, she became reconciled to his being thus employed, though she little dreamed of what he had really to go through. When he had shorter hours of work, he employed his time at home in reading and improving himself in writing. He had also a fancy for making models. He began by making one of the parts of the pit in which he worked. Then he tried his hand at making some of the simpler machinery of the pit. His uncle acknowledged that the rolleys, corves, picks, and spades were wonderfully exact,--indeed, was so well pleased that he allowed him a lantern and a supply of candles, so that instead of sitting in the dark, he could pass his time in reading and cutting out his models, the materials for which he carried down with him. So perfect were his models that they were readily purchased by visitors to the pit. His mother, on one occasion, taking some of them into a neighbouring town, sold specimens to tradesmen, who offered to buy as many as she could bring them of the same description. At length Mark became big enough to be a "putter," or rolley boy. He could no longer read or make models down in the pit, but he got better wages, shorter hours of work, and his health improved with the exercise. Being always wide-awake, he escaped the accidents from which so many of his companions suffered, which they called "laming." The injuries they received were from various causes, but generally from falling, when the rolley passed over their arms or legs, and broken limbs were the consequence. Some had lost one or more fingers or toes, others had received gashes in their faces, or arms, or legs, but they had seldom long been laid up, and had willingly again returned to their work. The term "putter," it should be understood, includes the specific distinction of the "headsman," "half-marrow," and "foal." The "headsman," taking the part of conductor, pushes behind. The "half-marrows" drag at the sides with ropes; while a "foal" precedes the train, also dragging by a rope. Mark, however, was not very long employed in this laborious task, for the overseer, hearing of his talent, appointed him to the duty of "crane-hoister." The term explains itself. He had to hook on the "corves," and keep an account by chalking on a board the number hoisted up. In this occupation he was able to gain a pound a week. Some part of this he laid by, and with the other
