No.  14,  single  cylinder,  fitted  with  automatic  expamsion  gear

that  it  is  satisfactory  to  see  that  it  is  coming  within  range  of 
adoption  in  the  ordinary  agricultural  steam  engine.  The  system 
used  in  this  case  is  that  known  as  “Schmitt’s,”  in  which  the 
.steam  is  superheated  in  a number  of  tubes  placed  in  the  smoke- 
box  which  is  made  longer  than  usual.
