SEVEN THINGS TO BE REMEMBERED
Never to stick pins into butterflies and other insects unless you would like to have somebody stick pins into you.
Never to carry fowl with their heads hanging down, unless you would like to be carried in that way yourself.
Never to throw stones at those harmless creatures, toads, unless you would like to have stones thrown at you in the same way.
That nearly all snakes are harmless and useful.
That it is cruel to keep twitching the reins while driving.
That you should always talk kindly to every dumb creature.
That you should always treat every dumb creature as you would like to be treated yourself, if you were in the creature's place.
