In the ignorance and inexperience of the young foreign girl the white slaver finds his easiest prey, and the betrayer is too often the man speaking her own tongue. On this terrible subject the nation, like other nations, is beginning to wake up to its responsibilities in relation to the immigrant girl as in relation to other girls. This special danger to young womanhood is so linked with other social questions that I merely allude to it here, because of the certainty I entertain that much even of this danger would lessen if the trade-union movement among women were so strong and so extensive that any woman, young or old, could travel from place to place as a member of a truly world-wide organization. Then she would have a better chance of arriving well posted as to ways of earning her living, and of finding friends in every city and every town and village. It may be urged that there exist already organizations world-wide in their scope, such as the religious associations, for the very purpose of safeguarding wandering girlhood. There are, and they accomplish a notable amount of good. But their appeal is not universal; they never have money or workers enough to cope adequately with a task like this, and they are not built upon the sound economic basis of the trade union. The immigrant problem was not encountered by the first factory workers here, who were American-born. So we find the earliest leaders in the trade organization of women were wholly drawn from the daughters of the native settlers. They felt and spoke always as free-women, "the daughters of freemen." When this class of girls withdrew from the factories, they gave place to the Irish immigrant, in some respects a less advanced type than themselves. I have briefly traced some of the economic reasons which affected the rise, growth and eventual passing away of the various phases of trade unionism among women in this country. The progress of these was radically modified by the influx into the trades of workers from one nation after another; by the passing from a trade or a group of trades of body after body of the old workers, starved out or giving way before the recent arrivals, whose pitiful power to seize the jobs of the others and earn some sort of a living, has lain in their very weakness and helplessness.
