TREES  AT  KEW. 
Deciduous  trees  and  shruts  constitute  the 
chief  portion  of  the  .'ittractivc  features  in  ii 
000(1  arboretum  during  iMa}’',  and  certainly  no 
better  season  can  be  selected  Ur  a  visit  to  this 
important  department  at  the  Royal  Gardens,  Kew. 
Even  those  who  a’'e  not  specially  interested  in  the 
admirable  collections  of  rare  and  beautiful  trees 
tliere  exhibited,  can  app.-cciate  the  wealth  of 
floral  beauty,  the  graceful  habit  of  growth,  or  the 
fiesb,  delicate,  and  varied  foliage  tints  on  every' 
tide.  With  strict  regard  to  the  scientilic  objects  of 
the  estahlishment,  an  observer  cannot  fail  to  notice 
that  consideiable  taste  has  been  displayed  in  the 
grouping  of  the  trees  in  many  parls,  and  tlio 
system  of  “  mas.dng,”  to  produce  telling  effecU,  is 
exactly  adapted  for  any  park  or  garden  avhcie 
.space  permits. 
The  advantages  of  such  a  method  are — First, 
that  a  group  can  be  formed  of  young  trees  or 
shrubs,  and  individual  defects  are  lost  in  the  mass ; 
secondly,  there  are  many  species  which  present  a 
rather  insignidcant  appearance  singly,  whereas  in 
bulk  they  have  a  good  nppeatance  ;  and  thirdly,  if 
individuals  arc  observed  to  ba  developing  in  a  way 
that  is  likely  to  render  them  li.ore  valuable  as  single 
specimens  they  can  be  removed  and  their  places 
filled  with  others.  The  beauty  of  a  finely  pro¬ 
portioned  healthy  specimen  tree  must  he  fully 
appreciated  by  all,  and  at  Kew  the  respective 
characteristics  of  the  same  species  can  in  many 
cases  b3  studied  both  in  grotiiis  and  as  single 
specimens.  , 
To  write  about  the  improve.nents  effected  in  our 
nalional  garden  within  recent  years  would  be  only 
recording  what  basj^bcen  repeatedly  noted  before, 
but  the  arboretum  has  shared  in  the  advance,  and 
less  is  heard  about  the  work.]  In  1708  it  is  officially 
stated  there  were  468  species  and  varieties  of  hardy 
tree 5  and  .'■brubs,  and  itds  now  said  there  are  over 
3000  in  the  collection.  ^But  it  has  noUbeeu  merely 
ill  the  increase  of  nnmbeis  that  improvement  is 
man'f  st,  the  nomenclature  lias  been  closely  ex¬ 
amined,  a  most  formidable  task,  with  the_  result 
that  seine  apjiroach  to  ordcrjl^has  been  securedjand
