  OF 
  THE

  and 
  adjacent 
  regions. 
  Reports 
  from 
  the 
  field 
  indicate 
  that 
  a 
  large 
  

   amount 
  of 
  herbarium 
  material 
  is 
  being 
  obtained 
  that 
  will 
  be 
  exceed- 
  

   ingly 
  valuable 
  in 
  current 
  studies 
  of 
  the 
  flora 
  of 
  western 
  South 
  

   America. 
  

  

  In 
  July 
  and 
  August, 
  1928, 
  Dr. 
  A. 
  S. 
  Hitchcock, 
  custodian 
  of 
  

   grasses, 
  visited 
  Newfoundland 
  and 
  Labrador 
  for 
  the 
  purpose 
  of 
  

   studying 
  and 
  collecting 
  grasses. 
  A 
  large 
  illustrative 
  series 
  of 
  speci- 
  

   mens 
  and 
  much 
  useful 
  information 
  regarding 
  the 
  range 
  of 
  species 
  

   in 
  these 
  little-explored 
  regions 
  were 
  obtained. 
  Mr. 
  Jason 
  E.. 
  Swallen, 
  

   assistant 
  in 
  the 
  grass 
  herbarium, 
  spent 
  the 
  summer 
  of 
  1928 
  in 
  field 
  

   work 
  in 
  the 
  southwestern 
  United 
  States. 
  Many 
  of 
  the 
  rarer 
  grasses 
  

   were 
  collected, 
  as 
  well 
  as 
  other 
  material 
  relating 
  to 
  current 
  studies. 
  

  

  Dr. 
  George 
  P. 
  Merrill, 
  head 
  curator 
  of 
  the 
  Department 
  of 
  Geology, 
  

   was 
  detailed 
  in 
  September, 
  1928, 
  to 
  visit 
  various 
  mineral 
  localities 
  in 
  

   the 
  New 
  England 
  States. 
  He 
  first 
  worked 
  at 
  the 
  pegmatite 
  deposits 
  

   at 
  Newry, 
  Me., 
  where 
  the 
  fine 
  block 
  of 
  material 
  mentioned 
  elsewhere 
  

   in 
  this 
  report 
  was 
  obtained. 
  The 
  historically 
  interesting 
  gem 
  locality 
  

   at 
  Paris 
  Hill 
  was 
  next 
  given 
  attention 
  ; 
  then 
  various 
  localities 
  in 
  New 
  

   Hampshire, 
  all 
  of 
  exceptional 
  interest. 
  Following 
  this, 
  the 
  feldspar 
  

   prospects 
  at 
  Bellows 
  Falls, 
  Vt., 
  were 
  examined. 
  The 
  acquisition 
  of 
  

   the 
  feldspar 
  vein 
  at 
  Newry, 
  Me., 
  was 
  considered 
  to 
  have 
  more 
  than 
  

   compensated 
  for 
  the 
  trip. 
  

  

  The 
  explorations 
  of 
  Dr. 
  W. 
  F. 
  Foshag 
  were 
  still 
  under 
  way 
  at 
  the 
  

   close 
  of 
  the 
  year. 
  He 
  reports 
  interesting 
  collections, 
  particularly 
  

   some 
  borate 
  minerals 
  from 
  various 
  localities 
  in 
  southern 
  California 
  

   and 
  Nevada. 
  A 
  part 
  of 
  this 
  material 
  has 
  reached 
  the 
  Museum, 
  but 
  

   the 
  recording 
  will 
  go 
  over 
  until 
  the 
  entire 
  collection 
  is 
  received. 
  

  

  Messrs. 
  James 
  Benn 
  and 
  B. 
  O. 
  Reberholt 
  were 
  on 
  several 
  occasions 
  

   detailed 
  to 
  collect 
  geological 
  specimens 
  in 
  adjacent 
  localities 
  in 
  Mary- 
  

   land 
  and 
  Virginia 
  where 
  desirable 
  materials 
  could 
  be 
  obtained. 
  

  

  Stratigraphic 
  studies 
  of 
  the 
  Cambrian 
  as 
  developed 
  in 
  the 
  larger 
  

   mountain 
  range 
  of 
  Wyoming 
  were 
  the 
  main 
  object 
  of 
  an 
  expedition 
  

   in 
  1928 
  by 
  C. 
  E. 
  Resser. 
  Nearly 
  three 
  months 
  were 
  spent 
  in 
  this 
  

   investigation, 
  in 
  the 
  course 
  of 
  which 
  several 
  mountain 
  ranges 
  were 
  

   explored. 
  Collections 
  of 
  fossils 
  were 
  limited, 
  the 
  rocks 
  in 
  many 
  

   cases 
  being 
  of 
  such 
  shallow-water 
  origin 
  that 
  the 
  fossils 
  have 
  been 
  

   destroyed. 
  Much 
  valuable 
  information 
  relating 
  to 
  stratigraphy 
  was 
  

   obtained. 
  

  

  Since 
  the 
  field 
  exploration 
  undertaken 
  by 
  C. 
  W. 
  Gilmore 
  and 
  his 
  

   part}^ 
  in 
  the 
  Two 
  Medicine 
  formation 
  in 
  Montana 
  extended 
  well 
  into 
  

   the 
  present 
  year, 
  but 
  brief 
  mention 
  was 
  made 
  of 
  it 
  in 
  last 
  year's 
  

   report. 
  The 
  expedition, 
  which 
  was 
  in 
  the 
  field 
  from 
  May 
  12 
  to 
  July 
  

   15, 
  1928, 
  covered 
  the 
  Bad 
  Land 
  areas 
  along 
  the 
  Milk 
  and 
  Two 
  Medi- 
  

   cine 
  Rivers,
