COLLEGE TO THE HIGHER 



EDUCATION OF WOMEN^ 



Thk retirement of Miss Thomas from the 

 presidency of Bryn Mawr College, whose des- 

 tinies she has guided since its formal opening 

 thirty-seven years ago — for nine years as dean 

 in association with President Rhoads, and for 

 twenty-eight as president — and whose ideals, 

 Ijolicies and achievements are in so large meas-

 education of women during her administration.

 members and friends of this college.

 period in the development of higher education 

 in this country. The path had already been 

 blazed for the collegiate education of women. 

 Each type of institution now recognized — the 

 coeducational, the affiliated and the separate col- 

 lege for women — had been in existence for sev- 

 eral years — the coeducational, indeed, for over 

 half a century— and with growing success. But 

 the hard-fought battle was still on. In order to 

 realize how complete has been the victory, how 

 great the advance, recall the changed attitude of 

 the public mind since those days toward college 

 education for girls, indeed the present wide 

 recognition of its vital importance for civiliza- 

 tion under the new social order, the many prob- 

 lems then open and now solved — although there
