catching me with tendrils invisible the tiny molecules of odor fill the air and smell makes me wonder that i dont see them how small they must be and i smell the fields and the dung they have just spread all over the field over there beyond the dike over there beyond the copse of juniper over there and still they catch me cow dung and horse dung but mainly cow dung thats what i think and all these molecules how small they must be is it true that one molecule of plutonium in a million of air molecules can kill you i dont think so but they sure are small .
