﻿ILLY 
  FOSTER 
  MINERALS. 
  

  

  Two 
  visits 
  were 
  made 
  during 
  April 
  to 
  the 
  Tilly 
  Foster 
  

   Mine, 
  and 
  two 
  entire 
  collections 
  were 
  purchased, 
  besides 
  

   many 
  smaller 
  lots 
  from 
  the 
  miners. 
  We 
  thus 
  secured 
  a 
  

   marvelously 
  fine 
  series 
  of 
  Chondrodites 
  and 
  Clinochlores, 
  

   and 
  as 
  that 
  portion 
  of 
  the 
  mine 
  in 
  which 
  they 
  were 
  found 
  

   will 
  very 
  soon 
  be 
  abandoned, 
  it 
  is 
  probable 
  that 
  no 
  more 
  

   good 
  specimens 
  of 
  these 
  minerals 
  will 
  be 
  obtained. 
  Our 
  

   purchases 
  fill 
  twenty 
  drawers, 
  besides 
  a 
  number 
  of 
  large 
  

   specimens, 
  and

   both 
  large 
  (up 
  to

  Xothing 
  to

  been 
  found 
  

   elsewhere.

  etc. 
  

  

  This 
  is 
  by 
  far 
  the 
  largest 
  and 
  best 
  series 
  of 
  the 
  rare 
  Tilly 
  Poster 
  minerals 
  ever 
  

   brought 
  together, 
  and 
  though 
  some 
  200 
  specimens 
  were 
  sold 
  within 
  a 
  few 
  days 
  

   after 
  we 
  received 
  them, 
  our 
  stock 
  is 
  still 
  replete 
  in 
  specimens 
  of 
  the 
  very 
  highest 
  

   grade. 
  This 
  will 
  very 
  likely 
  be 
  the 
  last 
  opportunity 
  of 
  securing 
  these 
  minerals, 
  

   and 
  certainly 
  no 
  such 
  marvelous 
  collection 
  of 
  them 
  is 
  likely 
  to 
  be 
  again 
  offered 
  for 
  

   sale. 
  

  

  A 
  GREAT 
  FIND 
  OF 
  RARE 
  QUARTZ 
  CRYSTALS. 
  

   Mr. 
  English 
  visited 
  a 
  new 
  localit}' 
  in 
  North 
  Carolina 
  and 
  secured 
  probably 
  the 
  

   most 
  interesting 
  pocket 
  of 
  Quartz 
  crystals 
  and 
  groups 
  ever 
  obtained 
  in 
  that 
  great 
  

   mineral 
  producing 
  state. 
  The 
  find 
  weighed 
  over 
  1400 
  lbs. 
  and 
  one 
  mammoth 
  

   group 
  of 
  splendid 
  crystals 
  15 
  x 
  32 
  x 
  30 
  inches 
  and 
  weighing 
  about 
  200 
  pounds, 
  

   another 
  splendid 
  group 
  14 
  x 
  20 
  x 
  8 
  inches, 
  more 
  than 
  a 
  score 
  of 
  other 
  museum 
  

   groups, 
  a 
  splendid 
  lot 
  of 
  medium 
  sized 
  and 
  small 
  groups 
  and 
  a 
  grand 
  collection 
  of 
  

   loose 
  crystals. 
  The 
  most 
  interesting 
  feature 
  of 
  the 
  crystals 
  is 
  the 
  exquisite 
  etching 
  

   which 
  is 
  sprinkled 
  over 
  some 
  of 
  their 
  faces 
  or 
  bevels 
  off 
  or 
  serrates 
  their 
  edges. 
  

   Pare 
  planes, 
  especially 
  low 
  rhombohedrons 
  abound 
  and 
  frequently 
  air 
  bubbles 
  

   course 
  through 
  large 
  cavities 
  containing 
  liquid. 
  There 
  are 
  also 
  many 
  crystals 
  with 
  

   huge 
  caverns 
  in 
  them, 
  crystals 
  grouped 
  in 
  parallel 
  position, 
  lustrous 
  smoky 
  crys- 
  

   tals, 
  beautiful 
  rutilated 
  amethystine 
  groups 
  of 
  crystals, 
  etc., 
  etc. 
  Give 
  us 
  permis- 
  

   sion 
  to 
  send 
  you 
  a 
  carefully 
  selected 
  box 
  on 
  approval 
  and 
  you 
  will 
  not 
  regret 
  it.

  FRENCH 
  CREEK 
  PYRITE. 
  

  

  The 
  French 
  Creek 
  Mines 
  are 
  now 
  closed, 
  probably 
  permanently, 
  and 
  we 
  have, 
  

   therefore, 
  been 
  buying 
  up 
  all 
  the 
  good 
  specimens 
  we 
  could 
  obtain. 
  Several 
  ship- 
  

   ments 
  have 
  been 
  received 
  of 
  the 
  curious 
  and 
  interesting 
  distorted 
  cubes, 
  cubes 
  

   with 
  rare 
  modifications, 
  etc. 
  Notwithstanding 
  their 
  impending 
  rarity 
  we 
  are 
  sell- 
  

   ing 
  them 
  at 
  lower 
  prices 
  than 
  ever, 
  10c. 
  to 
  $1.50. 
  No 
  Pyrites 
  of 
  this 
  character 
  

   have 
  been 
  found 
  elsewhere.
