A    MODEL    FOR  OTHERS. 
This^'type  of  aviary  may  be  repeated  in  almost  any  size.  If  a  whole 
room,  large  or  small,  can  be  set  apart  for  the  birds  the  same  arrangements, 
minus  the  partitioning  screen,  may  be  carried  out  on  a  larger  scale,  whilst  any 
odd  corner  of  a  room  which  has  a  fair  amount  of  space  and  is  nicely  lit  may 
be  enclosed  with  a  wire  front  in  the  same  way  and  the  arrangements  inside 
carried  out  on  a  proportionately  smaller  scale. 
OPEN-AIR  TREATMENT. 
To  come  to  out-door  aviaries  pure  and  simple,  two  types  will  be  found 
illustrated  which  may  be  taken  as  general  models  of  what  is  required  and  adapted 
to  any  place  or  need.  The  main  features  are  all  that  is  required,  and  given  good 
sound  materials  for  construction,  good  workmanship,  care  to  make  a  good  dry

floor,  impenetrable  by  mice  or  rats,  and  a  waterproof  roof,  all  other  details 
concerning  expense,  size,  and  decoration  may  be  regulated  by  the  space  at  one's 
disposal  and  the  condition  of  the  bank  account.  One  of  these  types  is  on  the 
lean-to  principle,  which  requires  an  existing  wall  to  erect  it  against,  and  is  most 
suitable  for  small  spaces  or  densely  built-over  areas,  where,  perhaps,  a  backyard 
forms  the  scene  of  one's  operations.  The  other  type,  which  contains  the  same 
general  features,  is  more  suited  for  open  spaces  where  it  can  stand  out  on  its  own, 
as  it  were,  and  form  an  ornament  to  a  lawn  or  similar  open  space  without  any 
supporting  structure. 
The  principal  feature  lies  in  the  triple  division  of  the  structure  into  closed-in, 
semi-open,  and  purely  open-air  sections,  each  one  communicating  with  the  other 
so  that  the  inmates  always  have  a  free  choice  of  going  out  in  all  weathers  or 
staying  indoors  if  they  prefer  doing  so.  The  making  of  a  vermin -proof  floor,  as 
Just  suggested,  is  a  comparatively^easy  matter.  The  soil  should  be  well  beaten 
down  in  the  first  instance,  and  the  whole  area  of  the  aviary  and  a  space  extending 
at  least  a  foot  beyond  all  its  limits  covered  with  a  solid  layer  of  broken  glass
