  LEAD,  n.  A  heavy  blue-gray  metal  much  used  in  giving  stability  to 
  light  lovers  --  particularly  to  those  who  love  not  wisely  but  other 
  men's  wives.  Lead  is  also  of  great  service  as  a  counterpoise  to  an 
  argument  of  such  weight  that  it  turns  the  scale  of  debate  the  wrong 
  way  An  interesting  fact  in  the  chemistry  of  international 
  controversy  is  that  at  the  point  of  contact  of  two  patriotisms  lead  is 
  precipitated  in  great  quantities. 
 
  Hail,  holy  Lead!  --  of  human  feuds  the  great 
  And  universal  arbiter;  endowed 
  With  penetration  to  pierce  any  cloud 
  Fogging  the  field  of  controversial  hate, 
  And  with  a  sift,  inevitable,  straight, 
  Searching  precision  find  the  unavowed 
  But  vital  point.  Thy  judgment,  when  allowed 
  By  the  chirurgeon,  settles  the  debate. 
  O  useful  metal!  --  were  it  not  for  thee 
  We'd  grapple  one  another's  ears  alway: 
  But  when  we  hear  thee  buzzing  like  a  bee 
  We  like  old  Muhlenberg,  "care  not  to  stay." 
  And  when  the  quick  have  run  away  like  pellets 
  Jack  Satan  smelts  the  dead  to  make  new  bullets.
