director  of  the  show,  to  enforce  obedience  to  regulations  necessary 
to  enable  the  judges  to  go  through  their  duties  with  comfort,  and 
to  guard  them  from  improper  interference  in  the  discharge  of 
the  same.  We  would  make  one  observation  more,  that  we  feel 
in  duty  bound  to  express  an  opinion  that  there  is  greater  se- 
curity, as  to  quality  of  work  and  durability,  to  the  farmer  in 
purchasing  an  engine  direct  from  the  manufacturers. 
At  the  end  of  the  remarks  which  we  now  proceed  to  make  on 
each  engine  separately,  will  be  found  a tabular  statement  of  the 
results  arrived  at  through  the  dynamometer.  The  following 
eigdit  engines  were  submitted  to  trial  : — 
Stand  12,  art.  1. — A four-horse  portable  engine,  manufactured 
by  George  Howe,  Southwark,  London,  but  exhibited  by  Dean, 
Dray,  and  Dean,  London.  The  workmanship  of  this  engine  was 
fair  but  not  first-rate,  crank  and  eccentric  being  of  cast-iron, 
which  is  objectionable;  slide-bars  strong  and  well  arranged  ; 
connecting-rod  and  crank-shaft  of  good  length  and  well  secured 
to  boiler,  which  is  peculiarly  constructed,  having  two  lateral 
openings  at  the  commencement  of  and  immediately  above  the 
fire-bars,  into  each  of  which  are  fitted  three  tubes,  traversing  the 
entire  length  of  the  boiler  and  opening  into  the  smoke-box  at 
the  end  ; the  force-pump  has  to  lift  its  water,  and  forces  through 
a heated  chamber  at  the  root  of  the  chimney  into  the  boiler. 
This  engine  performed  its  work  well  and  economically  as  regards 
fuel,  but  the  price,  2007.,  being  507.  per  horse,  is  much  too  high 
as  compared  with  the  better  class  of  engines  exhibited  by  other 
parties;  nevertheless,  we  could  not  pass  it  by  without  com- 
mendation. 
Stand  30.  art.  1. — A four-horsepower  portable  engine,  manu- 
factured and  exhibited  by  W.  C.  Cambridge,  of  Lavington  Iron 
Works,  Cathay,  near  Bristol.  The  steam  in  this  engine  could 
not  be  raised  higher  than  44  lbs.  per  square  inch,  43  lbs.  being 
the  Society’s  standard,  and  to  attain  to  this  pressure  required 
1|  hours.  The  slackness  of  draft  we  attributed  to  the  funnel 
passing  horizontally  along  the  boiler  and  then  rising  perpen- 
dicularly from  over  the  fire-box,  an  exceedingly  bad  arrange- 
ment. showing,  together  with  the  very  inferior  workmanship  of 
both  boiler  and  engine,  how  very  little  the  exhibitor  could  have 
been  aware  of  the  class  of  engines  he  would  be  brought  into 
competition  with  ; the  duty  performed  beintr  also  at  nearly  four 
times  the  cost  in  fuel  as  compared  with  the  prize  engines,  while 
the  price  per  horse  power  is  considerably  more. 
Stand  5.  art.  3. — A seven-horse  portable  engine,  manufactured 
and  exhibited  by  Clayton,  Shuttleworth,  and  Co.,  Lincoln. 
Workmanship  of  this  engine  very  good  and  arrangement  of 
working  parts  simple,  the  whole  mounted  on  strong  wooden
