four o'clock
To superintend this department was Miss Nunn 's chief duty , together with business correspondence under the principal 's direction . In the second room Miss Barfoot instructed her pupils , never more than three being with her at a time . A bookcase full of works on the Woman Question and allied topics served as a circulating library ; volumes were lent without charge to the members of this little society . Once a month Miss Barfoot or Miss Nunn , by turns , gave a brief address on some set subject ; the hour was four o'clock , and about a dozen hearers generally assembled . Both worked very hard . Miss Barfoot did not look upon her enterprise as a source of pecuniary profit , but she had made the establishment more than self-supporting . Her pupils increased in number , and the working department promised occupation for a larger staff than was at present engaged .
