On  the  Construction  of  Farm- Buildings.  233 
space,  including  walls  of  49  feet  2 inches  in  length,  and  21  feet 
in  breadth. 
As  the  height  of  the  stories,  the  thickness  of  the  walls,  the 
floor  of  the  second  story,  and  the  roof  ought,  in  every  respect,  to 
be  similar  to  what  has  already  been  described  ; it  is  then  only 
necessary  to  specify  those  particulars  of  the  building  in  question 
in  which  it  differs  from  that  already  treated  of. 
The  apertures  in  the  north  wall  of  the  straw-barn,  separating 
it  from  the  lower  story  of  the  barn,  have  already  been  described ; 
those  in  the  other  walls  are  as  follows : one  in  the  east  wall  for  a 
door  G feet  wide  and  8 feet  high,  to  have  a pan-piece  of  Memel 
fir  timber  12  inches  square  ; one  in  the  west  wall  for  a window, 
to  be  uniform  with  the  apertures  for  windows  in  the  lower  floor 
of  the  barn ; and,  in  the  south  wall,  two  for  open  cartways,  each 
8 feet  wide  by  8 feet  high,  separated  by  a pier  3 feet  wide  and 
of  the  same  thickness  as  the  other  walls,  and  to  have  pan-pieces 
of  Memel  fir  timber  12  inches  square;  also  one  for  a door  4 feet 
wide  by  7 feet  high,  communicating  with  the  stable  (No.  5),  to 
have  a lintel  of  Christiania  deal.  Hard  stone,  broken  into  small 
pieces,  and  well  rammed  upon  freestone  chips  and  rubble,  with 
stone  cills  at  the  openings  for  the  doors  and  cartways,  will  form 
a very  suitable  floor  for  the  straw-barn.  The  openings  in  the 
walls  of  the  granary,  or  story  over  the  straw-barn,  are — one  for 
a door,  communicating  with  the  upper  story  of  the  barn,  and 
already  described ; two,  for  one  window  each  in  the  east  and  west 
walls;  one  in  the  north  wall,  for  a window;  and  three  for 
windows  in  the  south  wall.  The  specification  for  the  apertures 
for  the  whole  of  the  windows  just  enumerated  are  to  be  in  every 
respect  the  same  as  that  for  windows  in  the  upper  story  of  the 
barn. 
The  doors  most  proper  for  the  building  now  treated  of,  are 
what  are  called  ledged-doors,  and  should  be  made  of  Norway 
battens,  slit  into  half  their  thickness,  with  door-frames  of 
Christiania  deal,  4i  by  3 inches  ; 3 inches  of  the  first-mentioned 
dimension  to  appear  within  the  opening  at  half  a brick  dis- 
tance from  the  external  surface  of  the  wall  when  of  brick,  or 
placed  in  a rebate  of  1J  inch,  at  6 inches  from  the  external 
surface  of  the  wall  when  of  stone.  The  door  on  the  lower  story 
of  the  barn,  in  the  north  wall,  will  most  conveniently  be  made 
in  two  parts  of  its  length ; and  that  in  the  upper  story  in  the 
same  wall  will  be  best  a folding-door,  opening  from  its  mid- 
breadth. The  door  best  adapted  for  the  aperture  6 feet  wide,  in 
the  east  wall  of  the  straw-barn,  is  a sliding-door,  furnished  at 
both  bottom  and  top  with  small  friction  rollers  orpullies,  running 
on  iron  rods.  The  whole  of  the  windows  for  the  lower  story  of 
the  barn,  and  also  that  for  the  west  wall  of  the  straw-barn,  may
