Dr. Bowley's[55] method is to compare the full-time weekly wage multiplied by fifty-two with the total wage bill for the year, divided by the number employed in the busiest week: that is, the week when it may be assumed that all persons dependent on the trade will be employed except those who are prevented by ill-health. Supposing, for example, the total wages bill in a certain trade were £400,000, and the number of persons employed in the busiest week were 16,000. The average amount per person per year would be £25 as compared with, say, £29 : 5s., which represents 52 times an assumed full-time weekly wage of 11s. 3d. We can thus say in this supposititious case that the yearly earnings of the workers in fact equal only 52 × 25/29-1/4, or 44 weeks at the full-time weekly wages. Owing to certain gaps in the statistical information these results are subject to certain qualifications of a nature somewhat too technical to enlarge upon in such a book as this. They may be accepted, however, as substantially establishing the fact that overtime does not in general counterbalance short time and slackness, and that in the foregoing review of earnings on the basis of a full-time week we have been dealing with figures which are distinctly rosier than the facts warrant. THE MOVEMENT AND TENDENCIES OF WOMEN'S WAGES A retrospect of women's wages based on such data as are available confirms the view that, low as is the present level, the movement is nevertheless in an upward direction. In the cotton trade, employing more than half the women in all textile trades, women's wages have risen continuously throughout the period of which we have information. Mr. G. H. Wood, F.S.S., who has made the movement of wages his special study, estimates that taking the general level of women's wages in 1860 as 100, the level in 1840 would be expressed by 75 and in 1900 by 160, so that in the period of sixty years covered by these figures women's rates of wages would appear to have increased by more than 100 per cent. Though perhaps not so considerable, a similar movement has occurred in other trades, and it is interesting to note that in Mr. Wood's view women's wages have risen relatively more than men's. Unfortunately, however, the statistics which are available, and on which his conclusion is based, do not include the great clothing and dressmaking industry which, from the point of view of women's employment, is so important. An enquiry on the lines of the 1906 Census was indeed attempted in the year 1886, but the results are meagre. It may be noted, however, that comparison of the results with those for 1906 tends to show that in some branches of the clothing trades wages declined. This fall in the rate of wages, if such a conclusion is justified, is, however, probably to be regarded as an exception to the general tendency as exhibited in the cotton and certain other trades.
