If you have ever paid any attention to the habits of animals, you will know that donkeys are remarkably cunning in opening gates. The way to stop them is to have two latches instead of one: a human being has two hands, and lifts up both latches at once; a donkey has only one nose, and latch a drops, as he quits it to lift up latch b. Bobus and I had the grand luck to see little Aunty engaged intensely with this problem. She was taking a walk, and was arrested by a gate with this formidable difficulty: the donkeys were looking on to await the issue. Aunty lifted up the first latch with the most perfect success, but found herself opposed by a second; flushed with victory, she quitted the first latch and rushed at the second: her success was equal, till in the meantime the first dropped. She tried this two or three times, and, to her utter astonishment, with the same results; the donkeys brayed, and Aunty was walking away in great dejection, till Bobus and I recalled her with loud laughter, showed her that she had two hands, and roused her to vindicate her superiority over the donkeys. I mention this to you to request that you will make no allusion to this animal, as she is remarkably touchy on the subject, and also that you will not mention it to Lady Mary. I wish you would both come here next year.
Always yours, my dear Charles, very sincerely,
