OBJECTS AND WORK OF THE COLLEGE. 



The aim of the College is, by means of systematic teaching, given in Evening Classes, to supply to women occupied during the day, a higher education 

 than has been generally within their reach. The Teachers are unpaid. The Lending Library, free to all members of the College, is open every Evening, 

 except Saturday, from 8 till lo. A Branch of the National Penny Bank has been established in the College for the convenience of students and members. 

 It is open every evening, except Saturday, from 7.30 to 10 o'clock. There is a Coffee and Conversation Room open every evening from 7.30 to ten o'clock, 

 where tea and coffee may be obtained. 



The College has been placed in union with the Society of Arts, and its students are thus enabled to attend the examinations, and obtain the certiJicates 

 of the Society, free of expense. The examinations are held in February and April. 



The following subjects are taught in the College :— English History', English Language and Grammar, Geography, Arithmetic, Precis Writing, Drawing, 

 Bookkeeping, Writing, Singing, French, Latin, German, English Literature, Physiology, and Hygiene. There are classes for Reading and Spelling on 

 four nights in the week. 



The College is almost entirely supported by voluntary contributions, as the fees paid by students are of necessity very low.
