Do not suppose that I didn’t write, hundreds of times: the difficulty has been with the directing. I directed the letters so violently at first, that they went far beyond the mark — some of them were picked up at the other end of Russia. Last week I made a very near shot, and actually succeeded in putting ‘Earls Terrace, Kensington,’ only I over-did the number, and put 12,000, instead of 12. If you inquire for the letter at No. 12,000, I dare say they’ll give it you. After that I fell into a feeble state of health, and directed the letters so gently that one of them only reached the other side of the room. It’s lying by the side of the window now.
— Lewis Carroll, letter to Mary MacDonald, Nov. 5, 1864
