  An 
  Observatory 
  party 
  skirted 
  the 
  edge 
  of 
  this 
  eastern 
  now 
  on 
  

   May 
  30 
  and 
  " 
  encountered 
  many 
  thin 
  narrow 
  tongues 
  (from 
  five 
  

   to 
  eight 
  or 
  ten 
  feet 
  (from 
  1*5 
  to 
  3 
  m.) 
  in 
  depth 
  and 
  from 
  fifty 
  

   to 
  two 
  hundred 
  yards 
  (46 
  to 
  180 
  m.) 
  in 
  width) 
  radiating 
  to 
  the 
  

   southeast 
  and 
  east. 
  These 
  departed 
  from 
  the 
  main 
  stream 
  at 
  

   higher 
  and 
  higher 
  points. 
  Wherever 
  junctions 
  were 
  seen, 
  the 
  

   departures 
  of 
  these 
  minor 
  branches 
  appeared 
  capricious 
  — 
  i. 
  e. 
  

   no 
  evidences 
  of 
  local 
  damming 
  or 
  pooling 
  were 
  seen. 
  Though 
  

   much 
  thinner 
  and 
  less 
  massive 
  than 
  the 
  main 
  stream, 
  these 
  

   were 
  still 
  fuming, 
  and 
  in 
  varying 
  degrees 
  the 
  air 
  above 
  them

  was 
  in 
  a 
  state 
  of 
  shimmer 
  from 
  heat. 
  The 
  emanation 
  of 
  the 
  

   fumes, 
  however, 
  furnished 
  a 
  more 
  reliable 
  indication 
  of 
  their 
  

   course 
  than 
  the 
  heat-disturbed 
  air 
  above 
  them."*
