Kelsier  knelt  beside  the  coin.  To  his  eyes,  a  faint  blue  line  —  almost  like  a  spider’s  silk  —  led  from  his  chest  to  the  coin.  In  fact,  hundreds  of  tiny  lines  pointed from his chest to each nearby source of metal. Iron and steel created these lines  —  one  for  Pushing,  one  for  Pulling.  Gemmel  had  told  him  to  burn  all  his  metals, but Gemmel often made no sense. There was no reason to burn both steel and iron; the two were opposites.
