“There is no branch of education called so universally into requisition as the art of letter writing; no station, high or low, where the necessity for correspondence is not felt; no person, young or old, who does not, at some time, write, cause to be written, and receive letters. From the President in his official capacity, with the busy pens of secretaries constantly employed in this branch of service, to the Irish laborer who, unable to guide a pen, writes, also by proxy, to his kinsfolks across the wide ocean; all, at some time, feel the desire to transmit some message, word of love, business, or sometimes enmity, by letter.”
