  But! Some of the notation used include:
  [Written up by: Ian T]

  Wide = a cross 
  Any runs are shown by placing a dot in the 
  appropriate number of quadrants.
  e.g. a wide that evades all fielders and the batsmen 
  run two would be entered as such

     * | *
    ---+---
       |

  No ball = A circle  If runs are taken off the bat 
  then the number of runs is shown inside the circle.  
  If runs are taken BUT not off the bat then the appropriate
  number of dots is included in the circle.
  If no runs are taken the symbol is obviously an empty circle.


  Wickets =  a 'w' or some use an 'x' BUT should always be w 
  as the x could 'tilt' and be mistaken for a wide.
  Runouts =  often shown with an 'r'  
  Byes = an upward facing, filled in, triangle    
  Leg byes = a downward facing, filled in, triangle 
  Runs are recorded with the number.  
  Dot balls are just that recorded with a dot.

  Email me(Ganesh or even Ian) for a truetype Font 
  that works with most windows software, especially 
  WORD.  Install it using the control panel/fonts thingy...
  It has almost all the standard cricket symbols.

 Also worth noting:-
 
  1.  An underline under the symbol indicates the batsmen 
     have ended up at opposite ends to that expected.  
     Usually as a result of 'one short' or crossing during 
     a dismissal. 
 
  2. Some scorebooks have a space below the bowling 
     summary to record the over number and the running 
     score for the bowler.  Keep this up to date and it's 
     worth its weight in gold - a very quick check when 
     looking for that elusive missed run when your sheet
     doesn't match your colleagues!  If the scorebook isn't 
     printed with that space then create it yourself by 
     marking out a small area in the corner of the summary 
     box.  If you include the over number then the game can 
     be completely 'replayed' with ease using the bowlers 
     summary and extras sections of the scoresheet - done                    properly, one can also find out how many balls each 
     batsmen faced.
