more than 111/2 hours a day, that is 12 hours for 5 days in the week, and nine on Saturday.

"Now the following analysis (!) will show that in a mill so worked, the whole net profit is derived from the last hour. I will suppose a manufacturer to invest £100,000:—£80,000 in his mill and machinery, and £20,000 in raw material and wages. The annual return of that mill, supposing the capital to be turned once a year, and gross profits to be 15 per cent., ought to be goods worth £115,000.… Of this £115,000, each of the twenty-three half-hours of work produces 5-115ths or one twenty-third. Of these 23-23rd8 (constituting the whole £115,000) twenty, that is to say £100,000 out of the £115,000, simply replace the capital;—one twenty-third (or £5000 out of the £115,000) makes up for the deterioration of the mill and machinery. The remaining 2-23rds, that is, the last two of the twenty-three half-hours of every day, produce the net profit of 10 per cent. If, therefore (prices remaining the same), the factory could be kept at work thirteen hours instead of eleven and a half, with an addition of about £2600 to the circulating capital, the net profit would be more than doubled. On the other hand, if the hours of working were reduced by one hour per day (prices remaining the same), the net profit would be destroyed—if they were reduced by one hour and a half, even the gross profit would be destroyed."[1]

  1. Senior, l. c., p. 12, 13. We let pass such extraordinary notions as are of no importance for our purpose; for instance, the assertion, that manufacturers reckon as part of their profit, gross or net, the amount required to make good wear and tear of machinery, or in other words, to replace a part of the capital. So, too, we pass over any question as to the accuracy of his figures, Leonard Horner has shown in "A Letter to Mr. Senior," &c,, London, 1837, that they are worth no more than the so-called "Analysis." Leonard Horner was one of the Factory Inquiry Commissioners in 1833, and Inspector, or rather Censor of Factories till 1859. He rendered undying service to the English working class. He carried on a life-long contest, not only with the embittered manufacturers, but also with the Cabinet, to whom the number of votes given by the masters in the Lower House, was a matter of far greater importance than the number of hours worked by the "hands" in the mills.

    Apart from errors in principle. Senior's statement is confused. What he really intended to say was this: The manufacturer employs the workman for 11½ hours or for 23 half-hours daily. As the working day, so, too, the working year, may be conceived to consist of 11½ hours or 23 half-hours, but each multiplied by the number of working days in the year. On this supposition, the 23 half-hours yield an annual product of £115,000; one half-hour yields 1/23 × £115,000; 20 half-hours yield 20/23 × £115.000; = £100,000, i.e., they replace no more than the capital ad-
