We now come to the question: How is the labour intensified? The first effect of shortening the working-day results from the self-evident law, that the efficiency of labour-power is in an inverse ratio to the duration of its expenditure. Hence, within certain limits what is lost by shortening the duration is gained by the increasing tension of labour-power. That the workman moreover really does expend more labour-power, is ensured by the mode in which the capitalist pays him. In those industries, such as potteries, where machinery plays little or no part, the introduction of the Factory Acts has strikingly shown that the mere shortening of the working-day increases to a wonderful degree the regularity, uniformity, order, continuity, and energy of the labour. It seemed, however, doubtful whether this effect was produced in the factory proper, where the dependence of the workman on the continuous and uniform motion of the machinery had already created the strictest discipline. Hence, when in 1844 the reduction of the working-day to less than twelve hours was being debated, the masters almost unanimously declared “that their overlookers in the different rooms took good care that the hands lost no time,” that “the extent of vigilance and attention on the part of the workmen was hardly capable of being increased,” and, therefore, that the speed of the machinery and other conditions remaining unaltered, “to expect in a well-managed factory any important result from increased attention of the workmen was an absurdity.” This assertion was contradicted by experiments. Mr. Robert Gardner reduced the hours of labour in his two large factories at Preston, on and after the 20th April, 1844, from twelve to eleven hours a day. The result of about a year’s working was that “the same amount of product for the same cost was received, and the workpeople as a whole earned in eleven hours as much wages as they did before in twelve.” I pass over the experiments made in the spinning and carding rooms, because they were accompanied by an increase of 2% in the speed of the machines. But in the weaving department, where, moreover, many sorts of figured fancy articles were woven, there was not the slightest alteration in the conditions of the work. The result was: “From 6th January to 20th April, 1844, with a twelve hours’ day, average weekly wages of each hand 10s. d., from 20th April to 29th June, 1844, with day of eleven hours, average weekly wages 10s. d.” Here we have more produced in eleven hours than previously in twelve, and entirely in consequence of more steady application and economy of time by the workpeople. While they got the same wages and gained one hour of spare time, the capitalist got the same amount produced and saved the cost of coal, gas, and other such items, for one hour. Similar experiments, and with the like success, were carried out in the mills of Messrs. Horrocks and Jacson.
