We nabbed this from Random Good Stuff.
The entire manuscript of this story was written with the E type-bar of the typewriter tied down; thus making it impossible for that letter to be printed. This was done so that none of that vowel might slip in, accidentally; and many did try to do so!
In writing such a story, purposely avoiding all words containing the vowel E, there are a great many difficulties. The greatest of these is met in the past tense of verbs, almost all of which end with -ed. Therefore substitutes must be found; and they are very few.
