In the smaller group, which includes the College for women of Western reserve university and the H. Sophie Newcomb memorial college, the affiliated college tends to become an entirely separate institution; in its instructors and instruction it differs widely from the institution to which it is affiliated; it is, in fact, a different college called into existence by the same authorities. In the larger group, which includes the Women’s college of Brown, Barnard and Radcliffe, the affiliated college tends to blend itself with the institution to which it is affiliated in a new coeducational institution. The ideal in view is a complete identity of instructors and instruction and the law of economy of force forbids attaining this ideal by the duplication of the whole instruction given. It is less wasteful to double the number of hearers in any lecture room than to repeat the lecture. It is in the Women’s college of Brown that we find the closest affiliation and, accordingly, the nearest approach to coeducation. The corporation of Brown furnished the land on which Pembroke hall, the academic building of the Women’s college, was erected, and accepted the gift of the building when it was completed; Brown has from first to last openly assumed responsibility for its affiliated college in fact as well as name. In the graduate department of Brown there is, as has been said, unrestricted coeducation; and in many of the smaller undergraduate elective courses women are reciting with men. In the graduate department of Columbia there is now unrestricted coeducation. It is in the case of Radcliffe that there is least approach to coeducation. What has made possible the policy pursued at Radcliffe has been the self-sacrificing zeal of many eminent Harvard professors, willing at any cost of inconvenience to give to women what could seemingly on no other terms be given; but the sacrifice is too great, and in the modern world too unnecessary; it is at present almost everywhere possible for the professor interested in educating women to lighten his own labors by admitting them to the same classes with men. Only the affiliated colleges of the second group present in their internal organization a type essentially different from that of the independent college—a type intermediate between the independent and the coeducational.
