The  Fly-wheel  (A)  is  raised  so  that  the  main  shaft  is  carried  just  under  the  upper-floor  joists. 
B,  Mill-stones  on  upper  floor,  worked  by  a bevel  wheel. 
C,  Spur-wheel,  driving  a drum  from  which  a belt  is  carried  to  the  shaft,  which  works  the  Chaff- 
cutter  and  other  small  machines  in  Straw-barn. 
to  open  outwards , as  has  been  recommended  by  several  coroner’s 
juries,  before  whom  repeated  instances  have  been  given  of  death 
from  scalding  when  an  explosion  has  occurred,  in  consequence  of 
the  escaping  steam  having  closed  the  doors  of  the  engine-house, 
thus  preventing  the  exit  of  those  within ; whereas,  had  they 
opened  outwards,  the  force  of  the  steam  would  rather  have  driven 
them  open.  As  a further  security  against  accident,  the  engine- 
house  is  nearly  detached  from  the  rest  of  the  buildings,  and  is 
divided  by  a thick  wall  from  the  small  part  with  which  it  is  in 
contact.  It  may  have  a fire-proof  ceiling  and  brick  or  stone 
floor. 
Steaming-room  and  Root-house  (e). — The  room  for  cooking  the 
several  articles  of  food  prepared  by  the  machinery  comes  next  in 
succession.  The  agent  employed  would  be  chiefly  the  waste 
steam  from  the  engine,  which,  instead  of  being  blown  up  the  flue, 
may  be  conducted  by  an  underground  pipe,  and  turned  on  or  off 
by  a cock.  When  the  steam  is  not  got  up  for  the  engine,  it  may 
be  supplied  by  a boiler  in  the  steaming-house,  which  also  serves 
for  boiling  linseed,  roots,  pig-wash,  &c.  This  being  provided 
with  a lid  fitting  into  a water-joint,  the  steam  from  it  is  conveyed 
down  through  a pipe  between  the  true  and  the  false  bottom  of  a 
wooden  chest,  the  latter  pierced  with  holes,  by  which  the  steam 
ascends  through  the  chaff,  linseed,  meal,  roots,  &c„  placed  in  the 
chest.  A cock  at  the  bottom  lets  off  the  condensed  water.  A 
root-house  (p),  with  wide  doors  to  allow  a cart  to  be  backed  into
