Report  on  the  Exhibition  of  Implements 
various  manufactures,  performs  the  most  delicate  operations  and 
produces  the  most  exquisite  fabrics,  the  comparatively  rough 
operation  of  threshing  corn  and  perfectly  dressing  it  has  not  yet 
been  accomplished,  or  machines  for  that  purpose  encouraged  by 
the  Society.  We  would  also  call  the  attention  of  the  Stewards 
and  Council  to  the  desirableness  of  giving  a prize  to  fixed  thresh- 
ing machines  with  dressing  apparatus  attached,  and  also  to  fixed 
steam-engines.  There  is  one  decided  advantage  in  a fixed  engine, 
that  it  will  cost  the  farmer  less  in  the  first  instance  than  a portable 
one,  very  much  less  for  repairs,  and  we  are  given  to  understand 
that  the  construction  of  the  boiler  can  be  simplified  and  made 
upon  a more  durable  plan,  when  weight  is  not  objectionable,  as  it 
would  be  in  the  portable  engine.

A Two-liorse  Threshing-Machine , belonging  to  Mr.  Garrett. — 
This  machine  was  first  tried  in  threshing  wheat.  It  threshed 
100  sheaves  in  4 minutes  and  5 seconds;  the  power  required  to 
work  it,  as  indicated  by  the  diagram  of  the  testing  machine, 
averaged  28 ' 39  lbs.,  being  equal  to  4' 16  horses.  This  power, 
multiplied  by  the  time  in  minutes,  equal  to  16-98  horses  to  thresh 
100  sheaves  of  wheat  in  one  minute. 
The  power  required  to  work  the  machine  empty  was  then 
tested,  and  it  was  found  to  take  -71  horse,  being  ‘65  horse  for 
the  barn-works  and  ’06  for  the  horse-works. 
It  was  next  tried  in  threshing  barley.  A quantity  of  sheaves 
were  counted  out  and  threshed.  The  time  taken  was  8 minutes 
7 seconds ; the  counter  of  the  testing  machine  registered  850 
revolutions  during  that  time,  and  the  average  power,  as  indicated 
by  the  diagram,  equalled  18-14  lbs.  During  this  experiment 
the  machine  worked  well,  and  was  fed  in  a very  regular  manner, 
but  it  was  ascertained  that  a mistake  had  been  made  in  the 
number  of  sheaves  given  to  it,  and  it  was  decided  to  have  the 
experiment  repeated.  Fifty  sheaves  of  barley  were  then  counted 
out,  and  the  machine  commenced  threshing,  but,  by  some  over- 
sight of  the  assistant,  the  tracing-pencil  was  not  put  to  work,
