be  exactly  alike,  and  a construction  of  window  well  adapted  for 
the  purposes  of  the  building  may  perhaps  be  easily  understood, 
by  assistance  of  the  following  figures: — 
log.  1. 
Fig.  2. 
Fig.  1 represents  a front  view  or  elevation  of  the  frame  of  the 
windows  in  question,  and  will  be  best  of  Christiania  deal,  4^  by 
3 inches;  3 inches  of  the  first-mentioned  dimensions  to  appear 
within  the  aperture  in  the  wall,  and  at  the  same  distance  from  its 
external  surface  as  previously  specified  for  door-frames ; a portion 
of  the  space  of  the  frame  in  its  upper  part,  9 inches  high,  to  be 
separated  by  a transom  3 inches  square,  and  divided  into  four 
panes  by  moulded  vertical  bars ; the  space  below  the  transom  to 
be  divided  by  an  upright  mullion  3 inches  square,  and  furnished 
with  ledged-sliutters  f inch  thick,  which,  closing  into  a rebate 
l£  inch  deep,  will  shut  with  the  ledges  of  the  shutters  flush 
with  the  inside  surfaces  of  the  frame,  transom,  and  mullion. 
Fig.  2 represents  a vertical  section  of  the  window  just  described, 
with  head,  lintel,  cill,  and  portion  of  the  wall.  The  purposes  of 
the  upper  story  of  the  barn  and  those  of  the  granary  requiring 
constant  admission  of  air  and  exclusion  of  wet,  windows  with 
Venetian  lattices  will  be  the  best  adapted  for  the  purpose.  The 
frame  ought  to  be  the  same  as  that  last  described,  and  its  space 
divided  in  the  whole  height  by  an  upright  mullion  of  3 inches 
square  ; the  lattice-frame  of  the  shutters  may  be  2 inches  square, 
and  the  lattices  f inch  thick,  2 .inches  apart,  and  slanting  half- 
square downwards.  The  shutters  so  constructed  and  hung, 
that,  closing  into  a rebate  2 inches  deep,  will  shut  flush  with  the 
inside  surfaces  of  the  window  and  mullion.  Fig.  1 below  is  a 
front  view  or  elevation  of  the  window  described,  and  Fig.  2 its 
vertical  section,  with  the  head,  lintel,  cill,  and  a portion  of  the 
wall. 
A hatch  in  the  floor  of  the  upper  story  of  the  barn,  for  hoisting 
corn  through  when  thrashed  and  dressed,  to  be  stored  in  the
