If I hold her up in front of the map of London

I have a cat who, if I hold her up in front of the map of London, will place her paw upon any principal building I like to name. The cat has been used to be carried round the room to catch flies on the wall. The principal buildings in the map are marked with square black spots, which she naturally mistakes for flies, so you have only to hold her in front of the map nearest to the spot you want her to touch, and slightly elevate your voice when you name the place, and the thing is done.
