“ Postmarks, which in themselves are worthless, we consider calculated to develop a knowledge of geography; for no American boy will rest content until he knows the exact locality from which his new postmark comes, and finds out all about it that his geography will tell him. Postage stamps have the same merit, with the advantage of being historical as well, as many of them contain heads of kings, queens, or eminent men, or at least some design typical of the country from which they come. ”
