With Trollope, though, we can always amuse ourselves by thinking that there might be more going on. Trollope, after all, spent years working for the post office. And in this novel, he tips the knowledgeable reader a quick wink:
Miss Stanbury carried her letter all the way to the chief post-office in the city, having no faith whatever in those little subsidiary receiving houses which are established in different parts of the city. As for the iron pillar boxes which had been erected of late years for the receipt of letters, one of which,--a most hateful thing to her,--stood almost close to her own front door, she had not the faintest belief that any letter put into one of them would ever reach its destination. She could not understand why people should not walk with their letters to a respectable post-office instead of chucking them into an iron stump,--as she called it,--out in the street with nobody to look after it. Positive orders had been given that no letter from her house should ever be put into the iron post.Trollope, famously, invented that hated pillar box.
T. S. Eliot, meanwhile, did Miss Stanbury one better--this story comes from The New Oxford Book of Literary Anecdotes, related by William Empson:
There was a party (I forget everybody else in the room) where Eliot broke into some chatter about a letter being misunderstood. "Ah, letters," he said, rather as if they were some rare kind of bird. "I had to look into the question of letters at one time. I found that the mistake . . . that most people make . . . about letters, is that after writing their letters, carefully they go out, and look for a pillar-box. I found that it is very much better, after giving one's attention to composing a letter, to . . . pop it into the fire." This kind of thing was a little unnerving, because one did not know how tragically it ought to be taken; it was clearly not to be taken as a flippancy.Letters never sent would do fine for a novel, but I suspect Eliot's method is a bit too arid for actual life.
