Consequent on this was another circumstance, scarcely less important in its effects than the former, which materially enhanced the tendency to excess of numbers in the manufacturing portions of the community. This was the encouragement given to the employment of _women and children in preference to men_ in most manufacturing establishments--partly from the greater cheapness of their labour, partly from their being better adapted than the latter for many of the operations connected with machines, and partly from their being more manageable, and less addicted to strikes and other violent insurrections, for the purpose of forcing up wages. Great is the effect of this tendency, which daily becomes more marked as prices decline, competition increases, and political associations among workmen become more frequent and formidable by the general popularising of institutions. The steam-engine thus is generally found to be the sole moving power in factories; spindles and spinning-jennies the hands by which their work is performed; women and children the attendants on their labour. There is no doubt that this precocious forcing of youth, and general employment of young women in factories, is often a great resource to families in indigent circumstances, and enables the children and young women of the poor to bring in, early in life, as much as enables their parents, without privation, often to live in idleness. But what effect _must_ it have upon the principle of population, and the vital point for the welfare of the working-classes--the proportion between the demand for and the supply of labour? When young children of either sex are sure, in ordinary circumstances, of finding employment in factories, what an extraordinary impulse is given to population around them, under circumstances when the lasting demand for labour in society cannot find them employment! The boys and girls find employment in the factories for six or eight years; so far all is well: but what comes of these boys and girls when they become men and women, fathers and mothers of children, legitimate and illegitimate, and their place in the factories is filled by a new race of infants and girls, destined in a few years more to be supplanted, in their turn, by a similar inroad of juvenile and precocious labour? It is evident that this is an important and alarming feature in manufacturing communities; and, where they have existed long, and are widely extended, it has a tendency to induce, after a time, an alarming disproportion between the demand for, and the supply of _full-grown labour_ over the entire community. And to this we are in a great degree to ascribe the singular fact, so well and painfully known to all persons practically acquainted with such localities, that while manufacturing towns are the places where the greatest market exists for juvenile or infant labour--to obtain which the poor flock from all quarters with ceaseless alacrity--they
