   I don't recall where I read it, or if was an actual   
   account or some piece of fiction, but I'm remembering   
   some sort of a device that counted each turn of a   
   wagon's wheel, thereby translating the number or   
   revolutions to distance traveled.   
      
   Something that those of us who do a lot of cross   
   country traveling on foot, by bicycle, etc. know   
   is that for a set pace, we can cover so many miles   
   in an hours time. In my case I am able to guess my   
   arrival time with fairly good accuracy because my   
   average speed on a bicycle is 15mph. I imagine the   
   old timers could apply the same logic to their time   
   traveled.
