198  On  the  Construction  of  Farm- Buildings. 
the  latter  being  conveyed  obliquely  by  a spout  to  the  chaff-house 
for  litter  on  one  side.  The  sacks  of  grain  can  be  either  loaded 
into  carts  directly  from  the  side-door  below  stairs,  or  may  be 
hoisted  up  through  a trapdoor  by  a hoist  attached  to  the  ma- 
chinery, as  in  a mill,  to  be  either  placed  in  the  granary  (c),  or,  if 
moist,  to  be  spread  on  the  floor  of  the  drying-room  ( h ),  which  is 
over  the  boiler,  the  engine  flue  passing  through  it,  and  being  also 
heated  by  steam  pipes  from  the  boiler  carried  under  the  floor,  as 
is  seen  at  West  Lambrook.  The  horse-corn  may  be  stored  in 
the  horse-corn  loft,  in  which  is  a hopper,  which  delivers  the  corn 
by  a spout  into  the  bin  below,  of  which  the  horse-feeder  may 
have  his  key,  as  well  as  of  the  corn-loft.  In  reference  to  this 
subject,  it  is  recommended  to  have  all  locks  made  of  a set,  so  that 
the  farmer  may  have  a master-key  which  will  open  all  the  locks, 
whilst  each  man  has  a key  which  will  open  only  its  own  lock. 
Oil-cake,  linseed,  beans,  barley,  and  other  things  to  be  crushed 
by  machinery,  or  ground  by  the  mill-stones,  may  be  stowed  in 
the  straw-barn,  as  also  the  hay  which  is  to  be  cut  into  chaff.  The 
best  machines  for  these  purposes  will  be  easily  ascertained  by  a 
reference  to  the  Reports  on  Implements  which  have  been  shown 
at  the  meetings  of  the  Royal  Agricultural  Society  in  the  Journal. 
It  may  be  mentioned  that  the  chaff-cutter  with  a spiral  knife, 
invented  by  Clyburn,  seems  well  adapted  to  steam  power,  being 
the  only  one,  it  is  believed,  in  which  the  cutting  instrument  is 
constantly  in  contact  with  the  material  to  be  cut,  and  thus  it 
works  regularly  without  blows  and  jerks.  This  instrument  is 
the  one  employed  in  extensive  works  at  Chalford  in  Gloucester- 
shire, where  paper  is  manufactured  from  straw,  and  where  im- 
mense quantities  are  cut  up  by  it  into  chaff’  daily. 
Engine  and  Boiler  House  (h,  c ). — The  machinery  above  de- 
scribed, to  which  may  be  added,  if  required,  a bone-mill,  pumps, 
or  a circular  saw,  is  supposed  to  be  driven  by  a six -horse  power 
engine,  with  plenty  of  boiler  room,  the  fly-wheel  being  elevated 
(as  shown  in  the  section),  so  that  the  main  shaft  may  pass  at  a 
height  of  7 feet  from  the  ground,  immediately  under  the  upper- 
floor  joists,  and  thus  give  head-room  for  passing  in  and  out  of  the 
barn  at  the  back.  This  wheel  is  cogged,  and  drives  a pinion-wheel 
from  its  upper  side.  The  whole  is  boxed  off  by  a partition,  so  as 
to  be  secure  from  accidents,  as  ought  to  be  the  case  with  all 
revolving  shafts  or  cog-wheels  which  are  at  all  within  reach,  as 
the  smock-frocks  of  the  men  and  the  dresses  of  women,  being 
caught  by  these  parts  of  the  machinery,  might  cause  serious  acci- 
dents. It  is  well  also  to  have  a bell-pull  in  the  engine-house, 
communicating  with  a bell  near  the  thrashing-machine,  by  which 
the  engineer  should  always  give  notice  before  he  lets  on  the 
steam.  All  the  doors  connected  with  the  engine-house  are  made
