  Twelfth 
  Report 
  of

  Mineralogist

  1894. 
  — 
  This, 
  the 
  

   second 
  biennial 
  report, 
  contains 
  a 
  discussion 
  of 
  the 
  mineral 
  indus- 
  

   tries 
  of 
  the 
  State 
  arranged 
  conveniently 
  under 
  subjects, 
  as 
  anti- 
  

   mony, 
  borax, 
  gold, 
  etc., 
  with 
  a 
  list 
  of 
  localities 
  by 
  counties 
  under 
  

   each 
  head. 
  Much 
  space 
  (pp. 
  70-322) 
  is 
  devoted 
  to 
  gold, 
  since 
  the 
  

   interest 
  in 
  gold 
  mining 
  has 
  much 
  increased 
  during 
  the 
  past 
  two 
  

   years. 
  The 
  annual 
  gold 
  product, 
  which 
  for 
  a 
  number 
  of 
  years 
  had 
  

   remained 
  between 
  twelve 
  and 
  thirteen 
  million 
  dollars, 
  is 
  expected 
  

   to 
  be 
  maintained 
  now 
  at 
  fifteen 
  to 
  sixteen 
  millions. 
  The 
  Report 
  is 
  

   thoroughly 
  illustrated 
  with 
  views 
  of 
  mining 
  works, 
  maps, 
  plans, 
  etc.

  BlaschJca 
  Glass 
  Models 
  of 
  Plants 
  

   and 
  Flowers 
  in 
  the 
  Botanical 
  Museum 
  of 
  Harvard 
  University. 
  — 
  

   These 
  specimens, 
  which 
  were 
  referred 
  to 
  in 
  the 
  last 
  number 
  of 
  

   this 
  Journal, 
  are 
  now 
  arranged 
  with 
  a 
  degree 
  of 
  completeness 
  

   which 
  renders 
  possible 
  a 
  general 
  consideration 
  of 
  their 
  origin 
  and 
  

   purpose. 
  

  

  In 
  planning 
  the 
  arrangement 
  of 
  the 
  Botanical 
  Museum, 
  the 
  

   Director 
  was 
  so 
  fortunate 
  as 
  to 
  secure 
  the 
  advice 
  and 
  cordial 
  

   cooperation 
  of 
  Mr. 
  Alexander 
  Agassiz. 
  In 
  the 
  preparation 
  of 
  the 
  

   plans 
  much 
  prominence 
  was 
  given 
  to 
  the 
  subject 
  of 
  a 
  synoptic 
  

   room, 
  where 
  the 
  types 
  of 
  vegetable 
  structure 
  could 
  be 
  compre- 
  

   hensively 
  displayed 
  somewhat 
  after 
  the 
  fashion 
  of 
  the 
  zoological 
  

   synoptic 
  room. 
  But 
  it 
  was 
  early 
  seen 
  that 
  dried 
  specimens 
  of 
  

   flowers 
  would 
  be 
  too 
  perishable 
  and 
  alcoholic 
  specimens 
  too 
  

   obscure 
  to 
  render 
  useful 
  any 
  attempts 
  in 
  this 
  direction 
  by 
  ordi- 
  

   nary 
  means. 
  Drawings 
  and 
  paintings 
  of 
  flowers 
  seemed 
  likewise 
  

   unsatisfactory. 
  Models 
  alone 
  remained. 
  Examination 
  of 
  the 
  

   available 
  models 
  in 
  papier 
  mache 
  showed 
  that 
  they 
  would 
  occupy 
  

   too 
  much 
  space, 
  and 
  be 
  possibly 
  misleading 
  in 
  the 
  qualities 
  of 
  

   texture 
  and 
  color. 
  

  

  It 
  occurred 
  to 
  the 
  present 
  writer 
  that 
  the 
  Blaschkas, 
  the 
  artists 
  

   who 
  had 
  constructed 
  the 
  exquisite 
  glass 
  models 
  of 
  marine 
  inver-
