  Palache 
  — 
  Epi 
  dote 
  and 
  Garnet 
  from 
  Idaho. 
  

  

  Chrysocolla 
  and 
  malacliite 
  occur 
  throughout 
  the 
  specimens 
  

   as 
  coatings 
  on 
  epidote 
  or 
  other 
  crystals 
  and 
  in 
  tiny 
  veinlets 
  

   which 
  penetrate 
  all 
  the 
  interstices 
  of 
  the 
  other 
  vein 
  minerals. 
  

  

  Brocbantite 
  was 
  found 
  in 
  several 
  specimens 
  in 
  slender 
  trans- 
  

   parent 
  emerald-green 
  prisms 
  or 
  in 
  radial-fibrous 
  aggregates 
  

   interspersed 
  among 
  the 
  epidote 
  crystals. 
  

  

  Hematite 
  has 
  been 
  already 
  mentioned 
  as 
  forming 
  thin 
  plates 
  

   parallel 
  to 
  faces 
  of 
  the 
  larger 
  garnets 
  ; 
  similar 
  plates 
  are 
  found 
  

   in 
  the 
  massive 
  epidote 
  and 
  in 
  quartzose 
  portions 
  of 
  the 
  vein.
