      This business of returning letters to the writers gives occupation to about sixty lady clerks in the “Return-Letter Department,” in the gallery up-stairs.

    • 1857 July 3, Augustus de Morgan, “[Correspondence between Sir William Rowan Hamilton and Professor Augustus De Morgan.] From A. De Morgan to Sir W. R.

    • 1993 February 25, Don Lander, “Curing Canadians of mail mania”, in The Ottawa Citizen, Ottawa, Ont., published 1993 March 1, page A8:
      Successes such as these have paved the way for our most recent marketing innovation. I refer to Canada Post edict No. 58291, stating that we will no longer redirect first-class mail without charge when households move. Ordering the new householder to re-envelope the mail and pay another 43 cents was a stroke of genius. New revenue potential is substantial — nearly 400,000 Canadians move to another province in any year and far more move within their province.
