I have proved by actual trial that a letter, that takes an hour to write,
takes only about 3 minutes to read!
The idea behind the experiment was to use a quote in another context to get it to say something
slightly different. Carroll’s words are used in a tautologic way: the words/letters, which are about
how long it takes to write a letter that is going to be read very fast, have taken literally
hours to write/weave across the gate, and (hopefully) won’t take more than 3 minutes
to be deciphered.
