'I'lioufiii  tticre  were  not  great  numbers  of  Orchids  at  the  Drill 
Hall  on  Tuesday,  May  16th,  several  Odontoglossuins  were  shown  that 
were  decidedly  above  the  average  for  (jiiality.  Two  of  these  we  now 
reproduce — namely,  Purity  (lig.  1)4)  and  Raymond  Crawshay  (tig.  95). 
The  latter  is  of  beautifully  rounded  form,  with  sepals  and  petals  of 
much  substance.  The  colour  is  white,  clouded  with  rose  purple,  and 
with  large  chocolate  blotches.  It  was  exhibited  by  de  Barri 
Crawshay,  Esq.,  Roselield,  Seveno<aks.  Purity,  as  the  name  implies, 
is  white,  save  for  the  slightest  rose  flushing  in  the  sepals  and  the 
yellow  on  the  base  of  the  lip.  Mr.  C.  J.  Salter,  gardener  to  T.  B. 
Haywood,  Esq.,  Woodhatch  Lodge,  Reigate,  was  the  exhibitor. 
Each  variety  received  an  award  of  merit  from  the  Orchid  Committee 
of  the  Royal  Horticultural  Society. 
plant  in  every  way.  It  is  questionable  in  fact  if  the  genus  contains  a 
liner  species,  strong  growing  and  flowering  abundantly,  the  blossoms 
emitting  a  delicious  fragrance  all  the  time  they  are  open.  To  get  the 
best  results  large  si)ecimens  should  be  grown  and  given  ample  head  and 
elbow  room  in  large  baskets  and  a  rough  compost  of  sphagnum  and 
charcoal.  So  treated  we  have  had  it  a  yard  high  and  as  much  through

Dendrorium  Jenkinsi. 
This  pretty  little  Dendrobium  blo.ssoms  much  more  freely  in  an 
intermediate  temperature  than  when  exposed  to  strong  heat,  and  will 
usually  be  satisfactory  when  well  established  on  rough  blocks  of  Apple 
or  other  hard  enduring  wmod.  The  small  size  of  the  pseudo-bulbs  aud 
leaves  prevents  anything  like  severe  drying  off  being  practised;  but 
unless  it  obtains  its  proper  rest  it  will  not  flower  freely,  and  this  is 
best  accomplished  by  removing  to  a  cooler  house  in  autumn.  The 
blossoms  are  orange  yellow,  with  a  deeper  tint  upon  the  downy  lip.  It 
is  named  after  a  Captain  Jenkins,  who  sent  it  home  from  Assam  in 
1836.— II.  R.  R. 
EVArORATED  VEGETABLES. 
Cattleya  citrixa. 
I  AM  greatly  indebted  to  the  Rev.  I’.  D.  Horner,  and  so  I  am 
sure  are  many  of  the  Orchid-growing  readers  of  the  Journal,  for  his 
verv  interesting  and  instructive  note  (page  381)  on  this  beautiful  species. 
I  had  ho])ed  that  more  correspondents  would  have  given  us  their 
experience  with  it,  and  waited  a  little  in  expectation,  but  this  is  a 
busy  time  of  year,  and  as  our  Editor  recently  pointed  out,  those  who 
are  most  expert  in  growing  are  not  always  the  most  expert  with 
the  pen,  and  vice  ver^a.  Let  us  hope  that  later,  when  the  press  of 
work  is  over,  our  Orchid  readers  will  give  us  their  experience  with 
this  and  other  “niifl’y”  kinds.  The  rev.  gentleman’s  experience  with 
C.  citrina  is  another  instance  of  successful  cultivation 
following  close  and  careful  observation  and  the  adoption 
of  cultural  methods  to  suit  the  natural  habit,  likes,  and 
dislikes  of  individual  species. 
The  factory  of  the  British  Preserving  Company  at  Rayne  stands  on 
a  plateau  about  200  feet  above  the  sea,  on  the  edge  of  the  London  clay, 
in  the  county  of  Essex,  upon  a  gravel  bed  25  feet  in  thickness,  overlaying 
a  bed  of  clean,  sharp  sand,  bearing  ample  w'ater  of  exceptionally  good 
quality,  though  very  hard.  In  the  erection  of  the  factory  great  attention 
w'as  paid  to  the  sanitary  arrangements  and  the  comfort  of  the  workers, 
most  of  whom  are  young  women.  The  main  hall  is  about  80  by  30,  and 
at  one  end  is  the  engine  and  boiler  room,  at  the  other  tho  kitchen  or 
copper  room,  with  store  room  and  the  workpeoples’  rooms  beyond.  On 
the  north  side  runs  an  annex,  in  which  are  various  bags  for  receipt  snd 
storage  of  the  raw  material  and  for  sundry  subsidiary  processes.  Outside 
there  is  a  forge,  a  tin  shop,  and  a  large  shed  for  baskets,  mats,  and  sacks, 
which  take  much  room.  The  most  scrunulous  cleanl-uess  must  be 
Dendrobium  cretaceum. 
Dendrobium  taurinum. 
Though  known  aud  admired  for  upwards  of  half  a 
century,  this  singular  Dendiobium  is  as  far  from  being 
understood  as  ever,  and  only  on  very  rare  occasions 
are  really  well-cultivateri  jdants  met  with.  Unlike  many 
other  species  that  are  difficult  to  do,  it  does  not  grow 
really  strongly,  even  when  first  impoited,  and  it  has 
become  an  understood  fact  that  if  the  plants  do  not 
take  a  good  hold  during  the  lirst  season,  they  are 
very  utdikely  to  do  so  at  all.  When  strong,  the 
newly  imported  stems  are  a  yard  and  more  in  height, 
but  such  are  rarely  produced  under  cultivation.  They 
are  quite  erect,  and  the  flowers  occur  at  or  near  the 
top  of  these,  in  many-flowered  racemes. 
The  long  twisted  petals  are  brown  and  purple,  the 
sepals  greenish-white,  while  the  lip  has  raised  lines  of 
brown  upon  a  rosy  purfile  ground  colour.  The  lip  and 
petals  have  been  likened  to  the  lace  and  horns  of  a  bull, 
hence  the  specifle  name.  The  only  house  it  is  likely 
to  succeed  in  is  a  hot,  moist,  and  exceptionally  light  one, 
and  during  the  period  of  the  greatest  root  activity  a 
laige  amount  of  water  must  be  given.  It  is  better  not 
to  attempt  any  drying  off,  though  when  the  growth  is 
made  the  plants  are  better  for  a  short  rest.  Unless 
ample  moisture  is  always  present  when  growth  is  active, 
insects,  and  especially  thri])s,  are  sure  to  attack  it,  and 
healthy  growth  will  be  out  of  the  auestion. 
Though  not  so  showy  as  others  in  this  section  the 
flowers  of  this  species  are  interesting  and  pretty,  and 
it  is  worth  a  place  where  arepresentative  collection  is 
aimed  at.  The  pseudo-bulbs  are  stout,  less  than  a  foot 
high ;  the  blossoms  occur  at  the  sides  of  tliese,  and  are 
milk  white  excepting  the  centre  of  the  lip,  which  is 
yellow  with  streaks  of  crimson.  It  is  best  grown  in  baskets,  not 
far  from  the  roof-glass  in  the  warmest  house,  well  watered  during 
the  growing  season,  but  kept  cool  and  dry  in  autumn  and  early 
winter.  It  is  a  native  of  large  tracts  of  country  in  Northern  India 
and  Assam,  and  was  introduced  in  1846.

In  this  line  species  the  racemes  are  much  larger  than  in  A.  odora-

observed.  The  concreted  floor  of  the  main  hall  is  channelled,  and  laid  so 
that  the  constant  flushings  of  water  pass  readily  away. 
The  main  feature  of  the  large  hall  (apart  from  the  shafting  and 
numerous  machines  connected  to  it  by  belting,  which  first  catch  the  eye) 
is  what  is  called  the  drying  canal.  This  runs  along  one  side  of  the 
building,  and  has  the  appearance  of  an  exaggerated  wooden  counter.  Its 
internal  dimension  is  about  1  feet  square,  and  throughout  its  length  is 
laid  a  small  tram  line,  along  which  run  the  waggons  containing  ten  or 
twelve  perforated  zinc  shelves  for  the  prepared  vegetables.  Outside  the 
canal  runs  a  similar  tram  line  by  which  the  waggons,  having  traversed 
the  canal,  are  returned  to  the  end  to  be  again  filled  and  passed  through. 
A  hot  blast  is  driven  into  the  canal  by  a  powerful  fan,  and  rapidly  takes
