  Steam  \Steam\,  n.  [OE.  stem,  steem,  vapor,  flame,  AS  ste['a]m 
  vapor,  smoke,  odor;  akin  to  D.  stoom  steam,  perhaps 
  originally,  a  pillar,  or  something  rising  like  a  pillar;  cf 
  Gr  ?  to  erect,  ?  a  pillar,  and  E.  stand.] 
  1.  The  elastic,  a["e]riform  fluid  into  which  water  is 
  converted  when  heated  to  the  boiling  points;  water  in  the 
  state  of  vapor. 
 
  2.  The  mist  formed  by  condensed  vapor;  visible  vapor;  --  so 
  called  in  popular  usage. 
 
  3.  Any  exhalation.  ``A  steam  og  rich,  distilled  perfumes.'' 
  --Milton. 
 
  {Dry  steam},  steam  which  does  not  contain  water  held  in 
  suspension  mechanically;  --  sometimes  applied  to 
  superheated  steam. 
 
  {Exhaust  steam}.  See  under  {Exhaust}. 
 
  {High  steam},  or  {High-pressure  steam},  steam  of  which  the 
  pressure  greatly  exceeds  that  of  the  atmosphere. 
 
  {Low  steam},  or  {Low-pressure  steam},  steam  of  which  the

  3,  and  Note.  In  the  illustration,  the  shell  a  of  the

  which  the  hot  gases,  from  the  fire  beneath  the  boiler, 
  enter  after  traversing  the  outside  of  the  shell,  and 
  through  which  the  gases  are  led  to  the  smoke  pipe  d,  which 
  delivers  them  to  the  chimney;  b  is  the  manhole;  c  the

  {Steam  gauge},  an  instrument  for  indicating  the  pressure  of 
  the  steam  in  a  boiler.  The  {mercurial  steam  gauge}  is  a 
  bent  tube  partially  filled  with  mercury,  one  end  of  which 
  is  connected  with  the  boiler  while  the  other  is  open  to 
  the  air,  so  that  the  steam  by  its  pressure  raises  the 
  mercury  in  the  long  limb  of  the  tume  to  a  height 
  proportioned  to  that  pressure.  A  more  common  form 
  especially  for  high  pressures,  consists  of  a  spring 
  pressed  upon  by  the  steam,  and  connected  with  the  pointer 
  of  a  dial.  The  spring  may  be  a  flattened,  bent  tube, 
  closed  at  one  end  which  the  entering  steam  tends  to 
  straighten,  or  it  may  be  a  diaphragm  of  elastic  metal,  or

  vertically  and  operated  by  a  vertical  steam  cylinder 
  located  directly  over  an  anvil.  In  the  variety  known  as 
  Nasmyth's,  the  cylinder  is  fixed,  and  the  hammer  is 
  attached  to  the  piston  rod.  In  that  known  as  Condie's,  the 
  piston  is  fixed,  and  the  hammer  attached  to  the  lower  end 
  of  the  cylinder.

  of  a  locomotive,  through  which  steam  is  rapidly 
  discharged,  producing  a  loud  whistle  which  serves  as  a 
  warning  signal.  The  steam  issues  from  a  narrow  annular 
  orifice  around  the  upper  edge  of  the  lower  cup  or 
  hemisphere,  striking  the  thin  edge  of  the  bell  above  it 
  and  producing  sound  in  the  manner  of  an  organ  pipe  or  a
