University women teachers can best help to secure equality of opportunity by rendering themselves indispensable members of the body corporate. In their case much is required of those to whom little is given. Above all they must avoid the temptation to live entirely in the absorbing interests of the present: they must remember that it is the business of a University to make contributions to learning as well as to teach. Secondly, they must insist on equality of payment and status when there is any disposition, overt or acknowledged, to differentiate on the score of sex. It is not right to yield on these points, for an important principle is at stake. On the other hand the time and place for insistence must be wisely selected, and any claim made must be incontrovertible on the score of justice and practicability. Lastly, women on committees and elsewhere are not justified in keeping unduly in the background. When they have something worth contributing to the discussion, it is not modesty but lack of business capacity, which makes them silent. "Mauvaise honte" is as much out of place as undue pertinacity. Women who are unwilling or unable to assert themselves when necessary, are not in place at a co-educational University. Most women, however, will derive intellectual stimulus from the free interchange of opinion, possible only when both sexes are working happily together, with common interests and common aims. If relatively too much space in this article has been given to women's work at mixed Universities, the excuse lies ready to hand. In Women's Colleges there is, of course, no sex bar, and the way lies clear from the bottom to the top of the ladder. Conditions of appointment, tenure, and work do not greatly differ from those described, except in so far as the stipends tend to be lower, especially for more responsible posts, when these are ordinarily occupied by women. It is a sign of the times that in at least one Women's College in a mixed University, it has been recently necessary to rule that posts are open to men as well as to women, unless it is specially stated to the contrary. Thus, when the power is theirs, women also may be unwisely tempted to erect a new form of sex barrier. To do so would be to play into the hands of those enemies who are always raising the voice against equal pay for equal work. The most suitable candidate for a post is the one who should be selected, irrespective of sex. It is this principle that women are endeavouring to establish. They must do so by scrupulous fairness when the power is theirs: by making themselves indisputably most fitted, when they are knocking at the closed door.
