  both 
  cases 
  is 
  double 
  : 
  to 
  preserve 
  the 
  old 
  treasures 
  and 
  to 
  bring 
  

   in 
  new. 
  

  

  The 
  energy 
  shown 
  by 
  Baron 
  von 
  Mueller, 
  the 
  renowned 
  

   Government 
  Botanist 
  of 
  Victoria 
  and 
  by 
  various 
  Forest 
  de- 
  

   partments 
  in 
  encouraging 
  the 
  cultivation 
  of 
  timber 
  trees 
  will 
  

   assuredly 
  meet 
  with 
  success 
  ; 
  one 
  can 
  hardly 
  hope 
  that 
  this 
  

   success 
  will 
  appear 
  fully 
  demonstrated 
  in 
  the 
  lifetime 
  of 
  those 
  

   now 
  living, 
  but 
  I 
  cannot 
  think 
  that 
  many 
  years 
  will 
  pass 
  before 
  

   the 
  promoters 
  of 
  such 
  enterprises 
  may 
  take 
  fresh 
  courage. 
  

  

  Jn 
  a 
  modest 
  structure 
  in 
  the 
  City 
  of 
  Sydney, 
  New 
  South 
  

   Wales, 
  Mr. 
  Maiden 
  38 
  has 
  brought 
  together, 
  under 
  great 
  diffi- 
  

   culties, 
  a 
  large 
  collection 
  of 
  the 
  useful 
  products 
  of 
  the 
  vegeta- 
  

   ble 
  kingdom 
  as 
  represented 
  in 
  Australia. 
  It 
  is 
  impossible 
  to 
  

   look 
  at 
  the 
  collection 
  of 
  woods 
  in 
  that 
  Museum 
  or 
  at 
  the 
  similar 
  

   and 
  more 
  showy 
  one 
  in 
  Kew, 
  without 
  believing 
  that 
  the 
  field 
  

   of 
  forest 
  culture 
  must 
  receive 
  rich 
  material 
  from 
  the 
  Southern 
  

   hemisphere. 
  

  

  Before 
  leaving 
  this 
  part 
  of 
  our 
  subject, 
  it 
  may 
  be 
  well 
  to 
  

   take 
  some 
  illustrations 
  in 
  passing, 
  to 
  show 
  how 
  important 
  is 
  

   the 
  influence 
  exerted 
  upon 
  the 
  utilization 
  of 
  vegetable 
  products 
  

   by 
  causes 
  which 
  may, 
  at 
  first, 
  strike 
  one 
  as 
  being 
  rather 
  remote. 
  

  

  (1) 
  Photography 
  makes 
  use 
  of 
  the 
  effect 
  of 
  light 
  on 
  chroma- 
  

   tized 
  gelatin 
  to 
  produce 
  under 
  a 
  negative 
  the 
  basis 
  of 
  relief 
  

   plates 
  for 
  engraving. 
  The 
  degree 
  of 
  excellence 
  reached 
  in 
  

   modifications 
  of 
  this 
  simple 
  device 
  has 
  distinctly 
  threatened 
  

   the 
  very 
  existence 
  of 
  wood 
  engraving, 
  and 
  hence 
  follows 
  a 
  

   diminished 
  degree 
  of 
  interest 
  in 
  box-wood 
  and 
  its 
  substitutes.

  Iron, 
  and 
  in 
  its 
  turn 
  steel, 
  is 
  used 
  in 
  ship-building 
  and 
  

   this 
  renders 
  of 
  greatly 
  diminished 
  interest 
  all 
  questions 
  which 
  

   concern 
  the 
  choice 
  of 
  the 
  different 
  oaks, 
  and 
  similar 
  woods 
  :

  But 
  on 
  the 
  other 
  hand 
  there 
  is 
  increased 
  activity 
  in 
  

   certain 
  directions, 
  best 
  illustrated 
  by 
  the 
  extraordinary 
  devel- 
  

   ment 
  of 
  the 
  chemical 
  methods 
  for 
  manufacturing 
  wood 
  pulp. 
  

   By 
  the 
  improved 
  processes, 
  strong 
  fibers 
  suitable 
  for 
  fine 
  felt- 
  

   ing 
  on 
  the 
  screen 
  and 
  fit 
  for 
  the 
  best 
  grades 
  of 
  certain 
  lines 
  of 
  

   paper 
  are 
  given 
  to 
  us 
  from 
  rather 
  inferior 
  sorts 
  of 
  wood. 
  He 
  

   would 
  be 
  a 
  rash 
  prophet 
  who 
  should 
  venture 
  to 
  predict 
  what 
  

   will 
  be 
  the 
  future 
  of 
  this 
  wonderful 
  industry, 
  but 
  it 
  is 
  plain 
  

   that 
  the 
  time 
  is 
  not 
  far 
  distant 
  when 
  acres 
  now 
  worthless 
  may 
  

   be 
  covered 
  by 
  trees 
  under 
  cultivation 
  growing 
  for 
  the 
  pulp- 
  

   maker. 
  

  

  There 
  is 
  no 
  department 
  of 
  Economic 
  Botany 
  more 
  promis- 
  

   ing 
  in 
  immediate 
  results 
  than 
  that 
  of 
  Arboriculture. 
  

  

  V. 
  Vegetable 
  Fibers. 
  

  

  The 
  vegetable 
  fibers 
  known 
  to 
  commerce 
  are 
  either 
  plant 
  

   hairs, 
  of 
  which 
  we 
  take 
  cotton 
  as 
  the 
  type, 
  or 
  filaments 
  of
