The second class of work noticed as being done by women is work done on machines with or without power, and this includes a whole host of employments and an endless variety of problems. Machine tending, press-work, stamp-work, metal-cutting, printing, various processes of brass work, pen-making, machine ironing in laundries, the making of "hollow ware" or tin pots and buckets of various kinds; such are a few of the kinds of work that occur to me. Many of them have the interesting characteristic of forming a kind of borderland or marginal region where men and women, by exception, do the same kinds of work. It is in these kinds of work that difficulties occur in imperfectly organised trades; it is here that the employer is constantly pushing the women workers a little further on and the male workers a little further off; it is here that controversies rage over what is "suitable to women," and that recriminations pass between trade unions and enterprising employers. These kinds of work may be very hard, or very easy, they may need skill and afford some measure of technical interest, or they may be merely dull and monotonous, efficiency being measured merely by speed; they may be badly paid, but on the other hand they include some of the best paid of women's industrial occupations. They are in a continual state of flux, responding to every technical advance, and change in methods; they represent the industrial revolution at its tensest and most critical point. And to conclude, it is here that organisation for women is most necessary and desirable in the interests of all classes.
