By the evidence collected under the commission, it is proved that there are coal-mines at present at work in which some passages are so small, that even the youngest children cannot move along them without crawling on their hands and feet, in which constrained position they drag the loaded carriages after them; and yet, as it is impossible by any outlay compatible with a profitable return, to render such coal-mines fit for human beings to work in, they never will be placed in such a condition, and, consequently, they never can be worked without this child slavery! When the roads are six feet high and upward, there is not only ample space for carrying on the general operations of the mine, but the coals can be drawn direct from the workings to the foot of the shaft by the largest horses; and when the main roads are four feet and a half high, the coals may be conveyed to the foot of the shaft by ponies or asses. But when the main ways are under four feet, the coals can only be conveyed by children. Yet, in many mines, the main gates are only from twenty-four to thirty inches high. In this case, even the youngest children must work in a bent position of the body. When the inclination of the strata causes all the workings out of the main ways to be on inclined plains, the young labourers are not only almost worked to death, but exposed to severe accidents in descending the plains with their loads, out of one level into another. In many of the mines, there is such a want of drainage and ventilation, that fatal diseases are contracted by the miners. According to the report of the Parliamentary commission, about one-third of the persons employed in the coal-mines were under eighteen years of age, and much more than one-third of this number were under thirteen years of age. When the proprietor employs the whole of the hands, not only will his general overseer be a respectable person, but his underlookers will be taken from the more honest, intelligent, and industrious of the labouring colliers. Elsewhere, the rulers in pits are such as the rudest class is likely to produce. The great body of the children and young persons are, however, of the families of the adult work-people employed in the pits, or belong to the poor population of the neighbourhood. But, in some districts, there are numerous defenceless creatures who pass the whole of their youth in the most abject slavery, into which they are thrown chiefly by parish authorities, under the name of apprenticeship.
