there was a crystal ball under a sort of pink frilly tea cosy , and several sets of divinatory cards , and a pink velvet bag of rune stones , and one of those little tables on wheels that no prudent witch would touch with a ten-foot broomstick , and -granny was n't sure on this point - either some special dried monkey turds from a llamassary or some dried llama turds from a monastery , which apparently could be thrown in such a way as to reveal the sum total of knowledge and wisdom in the universe .
