On  the  Cost  of  Agricultural  Buildings. 
incubation,  is  by  means  of  warm  water  conveyed  in  pipes,  the 
water  being  heated  by  a boiler  in  the  scalding-room  adjoining 
the  dairy.  This  boiler  supplies  warm  water  to  the  dairy  in 
severe  weather. 
Both  warm  and  cold  water-pipes  are  carried  round  the  dairy 
for  cleansing  purposes,  also  for  raising  or  lowering  the  tempera- 
ture. From  a tank  erected  over  the  engine-house  next  the  barn, 
a pipe  is  laid  to  the  dairy ; and  the  fall  from  the  tank  being  con- 
siderable, the  water  rises  in  the  pipe  and  forms  a fountain,  the 
playing  of  which  also  assists  in  lowering  the  temperature  of  the 
building  in  hot  weather. 
The  Cattle-sheds  require  no  explanation  beyond  that  given  on 
the  plan,  except  that  the  strong  black  lines  here  (and  elsewhere) 
indicate  sunken  channels  formed  in  stone,  for  conveying  the 
urine  that  may  not  be  absorbed  by  the  litter  in  the  cattle-boxes  to 
the  liquid-manure  tanks.  All  the  other  farm  buildings  will  be 
sufficiently  explained  by  the  plan. 
The  strong  black  lines  in  the  roadways , as  shown  on  the  plan, 
indicate  the  drainage;  the  dotted  lines,  small  tanks  for  the  de- 
posit of  sediment.  These  tanks  have  removable  gratings  fixed 
over  them,  and  assist  in  carrying  rain  water  off  the  surface  of 
the  roads  through  the  gratings  into  the  drains  so  soon  as  it  falls, 
by  which  means  the  roads  are  nearly  always  in  a comparatively 
dry  state. 
The  house  commands  a good  view  of  the  premises,  has  a 
private  entrance  from  the  public  road,  and  direct  communication 
with  the  steading.  All  persons  coming  in  or  going  out  of  the 
steading  during  the  day,  may  be  seen  from  the  windows.  The 
office,  by  adjoining  the  house,  affords  facility  for  business  pur- 
poses ; and  the  room  next  this,  which  is  for  the  workmen,  affords 
them  an  opportunity  of  getting  their  meals  comfortably,  as  it  has 
a fire-place  in  it,  and  is  fitted  up  with  tables  and  benches ; and 
it  also  affords  the  farmer  or  steward  an  opportunity  of  knowing 
the  time  the  men  go  to  and  return  from  their  meals. 
The  multiplicity  of  operations  a steam-power  engine  is  capable 
of  performing  is  here  shown.  It  drives  the  threshing-machine  ; 
the  machinery  for  cutting  chaff,  turnips,  and  other  bulbous  roots; 
also  that  for  bruising  oats,  grinding  all  sorts  of  grain ; turning  a 
circular  saw,  working  a planing-machine,  raising  and  lowering 
grain  and  straw  to  and  from  the  ground-floor  to  the  floor  over 
the  barn — works  that  for  drawing  the  corn-stacks  by  rope  trac- 
tion from  the  corn-sheds  to  the  feeding-board  of  the  threshing- 
machine,  and  pumps  water  from  the  well  into  a tank  ; it  also 
raises  the  water  for  supplying  the  boiler.  Water  is  conveyed 
from  the  tank  to  all  the  farm  buildings  when  required,  also  to 
the  house.  In  case  of  fire,  the  engine  (an  eight-horse  power)
