Gadding about in the indoor greenhouse outside the Bank of Canada by a yap stone. It's a stone currency, a shimmering limestone that is not indigenous to Yap. The worth of a particular stone varies depending upon the size but also cost or difficulty of quarrying it. Did anyone die or get injured? Was it carved with seashells or steel? It may change hands but just stay put with word going around about who owns it now. It becomes a symbolic totem of thanks for a rare large expenditure of help.
