MOORE’S  RURAL  MEW-YORRER. 
CENTENNIAL  FLORICULTUnE. 
One  of  tlio  hajjpy  clisaj^iiointmonts  of  tbo  Ceu- 
tcniunl  is  that,  going  Ihoru  wjth  Uie  expectation 
of  being  crusJiwl  »J«l  iKsateu  alioiit,  one  looks 
about  in  ivslouiahnient  to  lintl  that  tboro  is  uo- 
wberc  a  crowd.  ITji!  bouses  of  exhibition  are  so 
iuinieusc,  so  many  and  «o  mdoly  separated— tbo 
objects  of  sjs'clal  interest  ao  wisely  distriluitcd, 
that  tlicro  is  no  reason  for  a  dense  ooll«x*iion  of 
licopic  at  any  one  point.  Tbns  the  floral  display 
inay  be  surveyed  at  leisure  and  atndied  without 
di.scoiiifort.  The  grand  collccUou  of  plants  in 
Horticulhu-al  ILill  iiietcud  of  lieioj;  vievred  by 
glimpses  over  other  i)cople's  sbouldors,  or  by 
waiting  for  a  crowd  Uj  i>ass  on,  may  bo  soon  from 
one  end  to  the  other  in  all  that  collective  beauty 
of  arrangement  and  grouping  that  so  enhanctw 
individual  effect.  In  tills  light,  airy  Btructine — 
in  its  fragrant  air,  among  tno  majestic  Palms, 
sprojeJing  Cycads,  stately  Pborminms,  fearless 
Sennv-j lines  and  sprightly  ForuH— as  if  every 
t  ropical  gem  bad  be.on  iilacod  around  atid  about, 
one  walks  in  freedom  and  gazes  Avitli  positive 
delight.  'I'lic  music  seems  a  siiperlluons  charm 
and  llie  ‘‘  savage  breast”  needs  no  soothing.  As 
if  llieiT.  were  too  many  delights,  the  contempla¬ 
tion  of  one  must  bo  abandoned  before  another 
can  b<!  hooded. 
There  are  few  buidor  looldng  plants  than  the 
Siwow'iiino,  but  whether  wo  select  a  u/ili-ti  or  a 
\’ti(cli!,  their  beauty  is  of  that  majestic  order 
that  Hite  liU:kmniaii,  C'/alkeay,  Miisax,  the  finer

Jbit  (bei-e  are  many  of  those  tropical  plants, 
several  of  ivLich  arc  mentioned  further  on,  that 
may  be  grown  in  <uir  consfnwatorios  and  even 
sitting-rooms  that  would  at  least  add  variety  of

Many  specimens  of  Pau^kiitun  ii/Uis  in  the 
main  part  of  the  building,  attract  much  attention. 
One  of  (he  best  is  Ion  feet  high— makes  four  ro

J’lio  Assain-palin  (^h'ufriyn  I'thilin)  has  a  clean 
stem  of  lifteen  feet  tbotigb  no  larger  than  th«,! 
wrist,  spreading  out  aud  drooping  gi-accfiilly  at 
tbo  top.  Latania  JSorfxmu'a  or  African  Pan- 
lialm  is  a  stately  object.  'Dio  jilant  from  wbioh

long,  ciu-vc  from  the  bottom  by  tbo  weight  of 
the  fans  so  as  to  make  tbejn  spread  over  a  circle 
not  less  than  forty  feet  circnmforenco.  Small 
sijocimons  of  tbi,s  pabn  may  Vie  jdaced  in  abuost 
any  plant-structure  and  thrive  (luite  well  even 
in  sittbig-rooms. 
A  plant  of  ICuphorhia  .<p/e/idcn»  is  an  instance 
of  skilful  training.  This  contrary,  prickly  thing

not  sujicrior  to  several  otliers,  is  marked  “  Owned 
by  Ivobcrt  Morris  of  Philadelphia  during  the  llc-

usual  appeiirance  of  haring  boon  blackened  by 
burning.  At  Ibo  top  is  a  fine  spread  of  loaves 
seven  feet  in  diameter.  'This  (lycad  is  compara¬ 
tively  hardy  and  is  benefited  by  exposure  to  the 
rabiB  of  summer.  And  the  same  may  be  said  of

bowover,  that  tbe  knowledge  that  we  can  at  any 
time  take  .a  loek  at  it  by  stopping  “  down  South,” 
deters  onr  florists  from  giving  it  a  place.

tion  of  what  is  duo  to  horticulture,  whether 
viewed  as  an  art  or  a  science. 
The  most  creditable  display  at  present  is  that

PLANT  EXCHANGES. 
We  see  the  following  in  the  London  Garden : 
“A  pamiihlct  was  put  into  my  hands  the  other 
day  by  a  botanical  friend,  entitled,  “  Itulcs  for 
the  Ijondon  Botanical  Exchangii  Club,”  that  is 
to  say,  a  club  meant  to  facilitate  the  exchange 
of  dried  specimens  of  plants.  Jly  friend,  how- 
evtw,  on  showing  it  to  me,  said — Why  cannot 
someUiing  of  this  sort  be  done  with  living  plants  ? 
Ajid  the  idea  seemed  to  me  to  bo  so  good  that  1 
vouturo  to  trouble  you  with  a  few  Unos  about  it. 
Any  one  who  is  trjiug  to  form  a  collection  of 
living  plants  must  know  how'  often  he  has  more 
of  some  rare  and  good  j)laut  than  j.erhaps  ho 
cares  for,  wliilo  another  person  would  bo  glad  to 
give  in  exchange  for  it  what  he  would  prize  very 
highly.  Indeed,  exohiingcs  ronong  the  lovers  of 
rare  and  bcmitifiil  ])laiits  are  not  nnfreciuont 
now. 
My  object,  then,  in  wuiting  this  letter  is  to  ask 
if  any  sysimn  could  ho  introduced  like  that 
alluded  to  above  by  whicJi  exchanges  could  bo 
made  more  easy  than  they  now  are  and  those 
wlio  are  pm'suiiig  the  same  end  could  he  brought 
into  contact  with  oaeJi  other.  Only  a  small  au- 
iiiial  subscription  would  be  retiuired,  a.s  in  the 
case  of  fhe  London  Botanical  Exchange  Club. 
The  greatest  difficulty  would  be  (^as  in  its  case) 
ill  (hiding  a  secretary  ;  hut  might  not  this  ollico 
be  held  in  turn  by  different  meiabera  ? 
It  would  not  then,  I  think,  bo  .so  very  burden¬ 
some.  Lists  of  desiderata  could  he  made  out 
and  there  would  thus  bo  very  great  assistance  in 
forming  collections.  At  all  events,  if  yon  tliuik 
it  worth  w'liile,  I  shall  bo  glad  if  the  idea  can  be 
ventilated  in  yom-  columns.  Nurserymen  would 
have  nothing  to  fear  from  it,  for  it  never  could  j 
take  effect  on  a  large  scale,  and  it  would  bo  only  | 
among  those  who  already  have  some  rare  and  | 
beautiful  plants  which  they  offer  to  others.  I 
think  it  would,  from  one  point  of  view,  even 
tend  to  the  pui-chase  of  rai'e  aud  expensive 
plants.  One  could  buy  them  with  a  view  of  ex¬ 
changes  after  a  little  time,  when  they  have  been 
multiplied." 
The  Editor  replies “  Wc  beheve  all  attempts 
to  establLsb  a  system  of  plant  exchanges  in  this 
country  have  hitherto  failed.” 
'The  floricultural  readers  of  the  Hukal  New- 
Yokkeu  will  remember  om  announcement  a 
month  ijT  so  ago  offering  to  publish  the  muaos 
of  plants  which  om  subscribers  wished  to  ex¬ 
change.  We  received  six  letters.  One  was  re¬ 
jected  as  being  an  advertisement — the  otliers 
wore  published. 
We  woi'o  not  aware  at  the  time  of  making  this 
exchange  offer  that  various  systems  had  been 
tried  and  had  failed  in  England  as  the  editor  of 
the  London  Garden’s  comments  would  indicate — 
and  we  deemed  the  plan  an  excellent  one  for 
those  who  loved  plants  and  who  were  too  poor  to 
purchase  them — a  belief  that  was  strengthened 
by  private  congratulatory  letters. 
Owing  to  changes  in  the  Burai.  management 
which  were  then  uudor  way,  the  annoimcement 
w’as  made  rather  late  for  exchanges  of  seeds  or  ' 
lilantfl  aud  this  may  have  caused  the  partial  ' 
failure  of  our  plan.  lu  the  fall,  Uowevei-,  when 
seeds  have  been  gathered— when  bulbs,  herba¬ 
ceous  aud  other  plants  have  been  removed  to 
the  house  and  when  hardy  things  may  be  trans-  ' 
jxirted  by  mail  or  express  in  safety,  we  will  again 
hold  ourselves  in  readiness  to  pubhsh  brief  lists 
from  our  subscriliere.  If  in  this  way  wo  can 
serve  thorn,  wo  shah  be  gliwl  to  do  it.  If  they 
are  not  to  be  served  m  tliis  way — why  wo  shall 
not  fed  the  worse  for  having  tiled  to  servo  them 
and  failed.

FLORICULTURAL  NOTES. 
Tlie  current  shoots  of  llbododondroiis  should 
bo  Hu-ipoiled  against  bigh  winds. 
Eucalyptus  Glotjulus. — Seedling  plants  of  this 
floiuish  finely  out  of  doors,  Tbo  leaves  change 
in  color  to  a  docidly  hlucish-grocn,  the  blue 
being  almost  as  decided  as  the  green.  'The 
loaves  grow  wider  (nr  less  Ian  eolato)  than  the 
sketch  we  gave  a  few  weeks  back — and  it  is  alto¬ 
gether  11  jirctty  plant  among  sub-tropical  8ul> 
jects. 
Areculus  Rufiicuniki,  the  red-flowering  Horse- 
chestnut.  Each  raceme  is  larger  than  that  of  a 
Hyacinth — very  much  like  it  in  general  apjicar- 
ance  and  ipiito  as  firctty.  'Die  price  of  a  good 
Jlyaciiith  bulb  is  a5  cents.  'I'lic  i>rit'0  of  a 
Horse-chestnut  tree  is  one  dollar.  By  the  time 
the  Jlyaeiulh  has  exhausted  itself  aud  hocomc-s 
wortliloss  (froiM  two  to  tluce  years  if  planted  in 
tile  ground)  the  Horso-idiestmit  in  its  season 
will  ho  blooming  ^irofnsely.  Not  to  count  its 
fresh,  ample  foliage  the  shade  it  offers  and  the 
beauty  it  adds  to  all  about— wo  have  then  and 
ever  after,  in  late  May  or  oaidy  June,  scores  of 
racoines  for  the  single  one  of  the  Hyacinth  that 
blooms  itself  out  of  oxisteuce  in  two  or  three 
springs.  We  do  not  think  less  of  tlie  brilliant 
Hyacinths— hut  wc  venture  to  hint  to  those  wlio 
buy  1,hom  by  the  dozens  for  winter  aindow  orna¬ 
ments  and  who  have  not  a  tree  about  their 
lionios.  that,  for  one  season,  they  get  along  with 
four  Hyacinths  less  and  invest  the  dollar  in  a 
red-tlowcring  Horse-ehcstnnt.

ANIMAL  PARASITES. 
PiioF.  Van  Bkneuen,  of  the  University  of 
Louvain,  Franoe,  has  recently  written  au  inter¬ 
esting  little  work  entitled  “Animal  I’arasitos 
and  Mossmatos,”  in  whicli  he  has  contrived  to 
compress  a  groat  deal  of  curious  information  re- 
goi'ding  a  subject  much  more  extended  than  the 
reofler  not  versed  in  modern  jirOgress  of  natural 
history  would  siijiposo.  Ho  divides  the  strange 
creatures  of  wliich  he  treats  into  three  classes ; 
I’irst,  measin.i,te8.  or  tlioso  who  join  others  to 
make  a  living,  or  a  home,  or  protoction ;  second, 
mutunlists,  or  animals  which  live  ou  each  other 
without  being  either  parasites  or  inessmatos ; 
aud  till  I'd,  the  parasites,  whoso  p»'ofcssion  it  is  to 
live  at  tlio  expense  of  tlicii' neighbors,  aud  whose 
only  employment  consists  in  taking  advantage  of 
Uieiii,  hut  jirndelltly,  so  as  not  to  endanger  then' 
lives. 
While  it  would  Isi  iiniMisaihlo  hero  to  follow  Uie 
numerous  dislineUons  which  he  draws  among  the 
members  of  these  different  classus,  it  will  per¬ 
haps  prove  iriterostiug  to  note  a  few  of  the  most 
odd  and  novel  peculiarities  of  the  creatines  be¬ 
longing  lo  each.  There  is  a  ilsh,  ho  tells  us, 
called  the  hatothann,  wliich  is  a  living  hoaixling- 
houso  for  the  Jienis/er,  an  eel-like  ammal.  Die 
latter  is  lodged  in  the  digestive  tube  of  his  Oom- 
lianioii,  and,  witliout  any  regard  for  the  ho,spi- 
tality  which  ho  receives,  seizes,  mi  hi.s  portion  of 
all  that  enters.  'The  angler  or  IteauHroie  of  the 
Mediterranean  often  hai'bors,  in  the  luonchial 
sac,  a  kind  of  eel,  Avhieh  is  abinidantly  aide  to  take 
care  of  itself,  but  prefers  to  live  a  life  of  idleness 
and  share  its  host’s  spoils.  The  shark  is  accom¬ 
panied  by  the  jiilot  fish,  winch  does  not,  as  is 
often  reported,  exist  on  tlie  leavings  of  his  larger 
companion,  but  on  his  owti  iudusti-y,  uad  doubt¬ 
less  finds  some  advantage  in  piloting  his  neigh¬ 
bor. 
Another  remarkable  fish,  the  iTiuora,  Uterally 
moors  itself  to  the  body  of  tlie  shark,  thus  eon- 
Yortiug  the  latter  into  a  veliide,  which  carries 
liim  about  without  exertion  ou  his  pari.  When 
ho  becomes  hiuigry  ho  lets  go,  and  hiuits  for  prey 
wherovei-  lie  may  happen  to  bo.  Tins  tenacity 
of  the  remora  in  attaching  itself  is  taken  advan¬ 
tage  of  by  fishermen  of  Mozambique  Channel  in 
order  to  cajiture  turllos  and  large  fish.  They 
pass  througli  the  tail  of  the  remora  a  ring  to 
which  a  cord  is  attached,  and  then  send  it  in  pur¬ 
suit  of  the  fii-st  passer-by  wliioli  they  consider 
worthy  to  be  caught.  The  fish  holds  ou  to  its 
prey  so  fii’mly  that  it  only  romiiins  to  haul  victim 
and  captor  in  by  the  line. 
There  is  a  crab,  of  the  family  of  inaitlo.',  which 
conceals  itself  in  the  substance  of  a  polypidom : 
it  is  common  in  tlie  Viti  Islands,  in  company  with 
a  gastei'opod  mollusc,  aud  both  of  them  assume 
the  exact  color  of  the  imlypidom,  'This  is  a  new 
kind  of  mimicry.  Another  crab  appropriates  a 
real  anemone  to  form  a  liiing  cloak  to  hide  it 
from  view,  in  order  that  it  may  spring  out  fi'om 
the  ambush  to  attack  prey.  Remarkable  marine 
creatures  are  the  Mryi,  a  kind  of  crustacean 
wliich  grow  very  large,  and  conceal  their  abdo¬ 
mens  no  longer  in  a  shell,  but  in  the  crevices  of 
rocks.  In  the  East  Indies  they  remain  on  land, 
and  even  climb  trees.  'They  have  so  much 
stroiigtli  in  their  jiinccrs  that  it  is  roUted  that 
one,  wliile  stretched  on  the  branch  of  a  tree, 
“  raiHod  a  goat  by  the  oars."  A  family  of  isopods 
are  rather  dangerous  messmates,  it  would  seem, 
for  tliey  cut  into  the  walls  of  their  host’s  stomach 
and  live  like  Sylarites  on  its  contents. 
The  most  interesting  fixed  messmates  arc  the 
cirrhipodes,  which  cover  the  skin  of  whales, 
which  they  never  ipiit  after  once  choosing  their 
abode.  Each  whale  lodges  a  iieculiar  species,  so 
that  the  crustacean  messmate  is  a  true  flag, 
which  Indicates  in  some  respects  tlie  nationahty. 
It  would  not  be  without  interest  for  voyagers 
who  are  naturalists  to  study  tliesc  living  flags. 
Among  tlio  mntualists  may  bo  mentioned  the 
ticks,  one  generic  species  of  which  has  twenty 
Rjiceios  of  w  hich  lives  on  the  dog.  another  ou  the 
oat,  and  another  on  tho  ox.  Fish  parasites 
multiply  BO  rapidly  that  tlioy  cover  their  hosts  as 
tliough  tlicy  took  tho  jilaco  of  scales.  Die  cod 
gives  lodging  to  aspecios  of  very  hoantifnl  shape, 
wliicli  in  its  tium  affords  a  resting  place  for  a 
still  smaller  organism.  In  tlie  midst  of  tlio  eggs 
of  tho  lobster  there  lives  an  animal  of  extreme 
agility,  which  om'  aulhors  considers  tho  most 
extraordinary  being  ever  subjected  to  the  eyes 
of  a  Zoologist.  “Lot  us,”  ho  says,  “imaghie  a 
clown  ill  a  circus,  with  his  limh.s  as  far  distended 
as  possible,  displaying  tlie  tricks  of  strengl  li  aud 
agility  on  a  heap  of  monster  cannon  balls  which 
ho  stmggIcH  to  surmount  -pl.ocing  one  foot 
fomiod  Rkc  an  air  bubble  on  one  boll,  the  other 
f<x)l  ou  another,  alternately  balancing  and  ex¬ 
tending  his  hisly,  folding  his  limbs  ou  each  other 
or  bending  his  body  upwards  like  a  caterpillar — 
and  then  we  sliall  have  but  an  imperfect  Idea  of 
the  attitudc.s  which  it  assumes  and  which  it 
varies  incessantly.” 
'I'hero  is  no  organ  whicli  is  sheltered  from  the 
invasion  of  parasites;  even  man,  cyslicerci 
have  been  found  in  the  iatorior  of  tlio  lobes  of 
tho  brain,  in  tlie  eyeball,  in  tJio  hooi't,  and  in  tho 
substance  of  tho  hones,  as  well  as  in  tlio  spinal 
marrow.  Each  kind  of  w  orui  has  also  its  favorite 
place ;  and  if  it  has  not  tho  chance  of  getting 
there,  in  order  to  undergo  its  changta,  it  will 
perisli  rather  than  emigi'ato  to  a  situation  which 
is  not  suitalile  hi  it.  One  kind  of  worm  inhabits 
the  digc.stive  passages ;  auoUier  occupies  tho 
fosse,  of  the  nose  :  a  thii’d,  tho  liver  or  tho  kid¬ 
neys.  Each  animal  lias  its  proper  parasites, 
which  c-an  only  live  in  tuiimals  liaving  afliiiity  to 
llieu’  iioculiar  host.  Thus  the  ascaris  nu/.slax, 
tho  guest  of  tlio  donuistio  cat,  lives  in  dillcrcnt 
siMjcies  of while  the  fox  so  nearly  resomb- 
ling  in  appearance  tlie  wolf  and  tlie  dog,  never 
cnlortains  the  ttenki  si  rrata,  so  eoinmoii  to  tlic 
latter  animal.  'The  same  host  docs  not  always 
harbor  tho  same  worms  in  diJlerenl  rogioiis  of 
the  globe.  Thus  the  l.irgo  tapeworm  of  hothrio- 
ctphalus,  is  found  only  in  Russia,  I’oland  and 
Hwilzcrland  :  a  small  tapeworm,  to nUt  nana,  is 
observed  nowhere  excei»t  in  Abyssinia,  and, 
strange  to  say,  tho  natives  consider  their  absence 
from  the  body  a  sign  of  ill-UeiUtli ;  the  awhyto- 
stoma  is  known  only  to  the  soutli  of  Europe  aud 
the  north  of  Africa,  ihojittiria  of  Mediuo  in  tho 
east  and  west  of  Africa;  and  the  Bilharzia,  a 
terrible  worm,  has  been  found  only  in  Egypt.

THE  OSTRICH  DOMESTICATED, 
An  English  settler  at  the  Caiie  of  Good  Hope 
gives  this  account  of  Ins  ostrich  stock  in  a  pri¬ 
vate  letter : — “  I  have  a  liock,  or  herd,  or  covey, 
or  whatever  else  you  like  to  call  it.  of  27 ;  they 
are  pcrfoclly  tamo,  and  will  follow  me  aU  over 
the  place ;  in  fact.  I  feel  sure  that  they  were  in¬ 
tended  to  be  domesticated.  I  have  only  to  get 
outside  and  whistle,  and  the  whole  trooii  conies 
as  fast  us  their  legs  can  carrj’  them  in  hopes  of 
getting  some  maize,  ivhich  they  are  very  fond  of. 
They  oat  almost  anything,  hut  there  is  so  much 
round  tlie  house  and  in  the  old  lands  that  they 
seai-eely  requii-e  any  artificial  food ;  hut  I  gener¬ 
ally  give  them  a  feed  of  luoernc  once  a  day,  and 
they  seem  to  relish  it  more  than  any  thing  else. 
'They  arc  plucked  first  at  about  eight  moaths  old, 
aud  afterwards  every  seven  mouths.  'Tho  feath¬ 
ers  are  not  of  much  value,  but  neveilheloss  re¬ 
turn  26  per  cent,  per  annum.  The  second  pluck¬ 
ing  brings  that  np  to  80  per  cent,  and  the  tliird 
about  1 10  or  more.  The  f  eathei-s  are  then  prime, 
and  the  yield  from  each  bird,  taking  cocks  and 
liens  together,  is  about  £9  or  £10.  The  price  of 
hiids  two  mouths  old  is  £9,  aud  I  intend  to  make 
np  my  number  to  To  tliis  season,  and  when  they 
are  full  grown  1  expeot  to  get  £750  a  year  for 
their  feathers  alone,  without  counting  inci-ease. 
Wild  birds  arc-  very  scarce  witlfiu  the  colony,  and 
arc  only  to  be  found  in  numbers  far  in  the  inte¬ 
rior,  where  they  are  also  raiiiiily  decreasing, 
'riiis  accounts  for  the  pnoo  of  feathers.  Of 
ooiu'se,  the  demand  is  incfea.siug  tluoughout  the 
world,  so  that  it  will  bo  many  years  before  the 
domesticated  biids  make  any  marked  difference 
in  the  market.  No  stock  gives  so  little  trouble  ; 
they  thrive  where  a  donkey  would  find  it  hard 
lines  to  live.’’
