wheels  well  constructed;  the  force-pump  delivers  through  a pipe 
passing  inside  the  boiler,  traversing  its  entire  length  and  deliver- 
ing its  feed  at  the  smoke-box  end.  This  arrangement  we  think 
bad  and  inconvenient,  for  although  the  pump-pipe  is  felted  and 
enclosed  in  an  outer  casing  5 inches  in  diameter,  which  also 
serves  for  the  exhaust,  there  will  he  some  little  condensation  of 
steam  take  place ; moreover,  the  outer  pipe  occupies  a consider- 
able portion  of  the  steam-room  of  the  boiler,  and  the  pump-pipe, 
in  case  of  repair,  is  difficult  to  get  at:  the  bearing  carrying  the 
end  of  the  slide-bars  we  think  has  not  sufficient  hold  on  the 
boiler,  as  it  only  covers  about  5 inches  square  at  the  part  where 
it  is  bolted.  The  force-pump  of  this  engine  has  to  lift  its  water 
between  5 and  6 feet,  which  would  be  better  avoided  if  the 
general  arrangement  of  the  engine  would  have  permitted.  The 
plates  in  the  fire-box  of  this  engine  had  been  ground  up  to  a 
face  previous  to  painting,  and  the  body  of  the  boiler  coated  with 
vermilion  and  varnished — expenses,  we  think,  quite  superfluous 
to  incur  when  exhibiting  an  engine  destined  for  the  farm-yard, 
f lie  duty  done  by  this  engine  will  be  seen  by  reference  to  the 
tabular  statement  to  have  been  very  good,  there  being  only  one 
other  in  the  trial-yard,  “ Hornsby  and  Son’s,”  which  excelled  it 
in  this  respect.  But  as  we  also  thought  that  engine  stronger 
and  more  durable  in  the  working  parts,  we  awarded  to  Clayton, 
Shuttleworth,  and  Co.  the  second  prize  of  25/. 
Stand  101,  art.  1. — A six-horse  portable  double-cylinder  engine, 
manufactured  by  Wm.  Butlin  of  Northampton,  and  exhibited  by 
Hodge  and  Bailey,  9,  Adam-street,  Adelphi,  London.  The 
workmanship  of  this  engine  was  moderate,  the  cylinders  on  the 
oscillating  principle — a complication  unnecessary  in  this  class  of 
engines.  The  duty  done  by  this  engine,  for  amount  of  fuel  con- 
sumed, was  less  than  any  other  in  the  trial-yard,  with  one  excep- 
tion, which  sufficiently  stamps  its  comparative  merits. 
Stand  8,  art.  9. — A nine-horse  portable  engine,  manufactured 
and  exhibited  by  Hornsby  and  Son,  Spittlegate,  Lincoln.  Work- 
manship of  this  engine  is  good,  and  boiler  strong;  the  cylinder 
is  placed  in  the  steam-chamber  of  the  fire-box — an  arrangement 
which  gives  an  unsightly  appearance  to  the  boiler.  We  found 
the  detail  of  this  engine  to  have  been  most  carefully  considered, 
and  every'  arrangement  made  to  facilitate  repairs  when  necessary. 
The  oil-cups  were  on  a very  good  and  efficient  principle,  and  the 
registered  apparatus  for  heating  the  water  previous  to  its  being 
forced  into  the  boiler  we  considered  very  good.  The  crank-shaft 
and  its  bearings  were  made  for  wear,  exceedingly  strong  and 
firm,  which  remark  will  apply  also  to  all  the  working  parts, 
forming  as  a whole  an  engine  well  suited  to  farm  purposes  (size 
excepted,  a nine-horse  being,  we  think,  too  large).  The  duty
