Drawing with a PC mouse.
     Drawing with a mouse has nothing to do with PC-graphic. It is real drawing.  The mouse as compared with pen or pencil  has its own faults and merits.  At the beginning it  is rather a clumpsy device  but it can be  easily overcome.  But to make up for it the drawings can be instantly placed into the text and printed which is expecially useful  for those who writes and illustrates his texts himself.
