The Apprentices’ Library Association, which has been formed but a short time, promises to be of great benefit to the apprentices of the place, by introducing among them, habits of reading and reflection, which, if properly attended to, will enable them to support the honourable character of good citizens.

About one hundred apprentices take books from it, regularly once a week.--This institution was incorporated by an act of the Legislature, passed in November, 1824.
