  taken 
  for 
  the 
  Geological 
  Survey 
  by 
  Mr. 
  W. 
  Harris, 
  in 
  the 
  Upper 
  

   Tuolumne 
  Valley, 
  near 
  Soda 
  Springs, 
  Mount 
  Dana, 
  Mount 
  Hoff- 
  

   mann, 
  and 
  Mount 
  Lyell. 
  He 
  also 
  presented 
  an 
  account 
  of 
  a 
  remark- 
  

   able 
  portion 
  of 
  the 
  Tuolumne 
  Valley 
  (Hetch-Hetchy 
  Valley), 
  which 
  

   forms 
  almost 
  an 
  exact 
  counterpart 
  of 
  the 
  Yosemite, 
  written 
  by 
  Mr. 
  

   C. 
  F. 
  Hoffmann, 
  the 
  head 
  of 
  a 
  party 
  of 
  the 
  Geological 
  Survey, 
  by 
  

   which 
  it 
  was 
  explored 
  the 
  previous 
  summer. 
  

  

  Dr. 
  A. 
  W. 
  Saxe 
  called 
  the 
  attention 
  of 
  the 
  Academy 
  to 
  a 
  local- 
  

   ity 
  which, 
  from 
  an 
  archaeological 
  point 
  of 
  view, 
  is 
  very 
  interesting, 
  

   and 
  which 
  has 
  never 
  been 
  examined 
  to 
  any 
  extent. 
  It 
  is 
  situated 
  

   just 
  south 
  of 
  the 
  mouth 
  of 
  Laguna 
  Creek, 
  six 
  miles 
  north 
  of 
  Santa 
  

   Cruz. 
  Here 
  is 
  a 
  mound, 
  standing 
  from 
  50 
  to 
  70 
  feet 
  above 
  the 
  

   ocean 
  level, 
  composed 
  of 
  material 
  which 
  was 
  in 
  all 
  probability 
  col- 
  

   lected 
  by 
  the 
  aborigines 
  of 
  the 
  country. 
  It 
  has 
  a 
  depth 
  of 
  from 
  

   twelve 
  to 
  fifteen 
  feet. 
  He 
  had 
  examined 
  only 
  those 
  parts 
  which 
  open 
  

   towards 
  the 
  gorge. 
  He 
  had 
  found 
  deposits 
  of 
  various 
  eras 
  inter- 
  

   spersed 
  with 
  what 
  he 
  regarded 
  as 
  drift 
  sand, 
  in 
  which 
  were 
  to 
  be 
  

   seen 
  all 
  kinds 
  of 
  implements 
  used 
  by 
  the 
  aborigines, 
  including 
  

   the 
  regular 
  arrow-head, 
  the 
  crescent-shaped 
  knife, 
  and 
  the 
  long 
  

   spear-head, 
  in 
  all 
  styles 
  of 
  manufacture. 
  What 
  was 
  of 
  especial 
  in- 
  

   terest 
  to 
  him, 
  was 
  the 
  discovery 
  of 
  tons 
  upon 
  tons 
  of 
  chalcedony 
  

   rock, 
  lying 
  in 
  the 
  immediate 
  vicinity, 
  of 
  the 
  kind 
  that 
  is 
  found 
  be- 
  

   low 
  Monterey 
  and 
  about 
  Pescadero. 
  These 
  boulders 
  had 
  an 
  aver- 
  

   age 
  diameter 
  of 
  four 
  inches, 
  the 
  limits 
  being 
  two 
  and 
  a 
  half 
  and 
  five 
  

   inches. 
  He 
  thought 
  that 
  a 
  ship-load 
  of 
  these 
  rocks 
  might 
  be 
  

   collected 
  thereabouts. 
  They 
  were 
  evidently 
  carried 
  thither 
  from 
  a 
  

   very 
  long 
  distance, 
  and 
  he 
  could 
  form 
  no 
  conjecture 
  as 
  to 
  where 
  the 
  

   aborigines 
  got 
  them 
  from. 
  They 
  were 
  probably 
  obtained 
  for 
  the 
  sole 
  

   purpose 
  of 
  manufacturing 
  implements. 
  

  

  Dr. 
  George 
  Hewston 
  said 
  the 
  English 
  sparrow 
  had 
  been 
  a 
  sub- 
  

   ject 
  of 
  inquiry. 
  He 
  could 
  not 
  see 
  the 
  reason 
  for 
  the 
  introduction 
  

   of 
  a 
  foreign 
  sparrow 
  which 
  had 
  some 
  objectionable 
  habits, 
  when 
  we 
  

   had 
  a 
  most 
  valuable 
  native 
  sparrow 
  that 
  should 
  be 
  protected 
  — 
  the 
  

   Western 
  white-crowned 
  finch 
  or 
  sparrow. 
  It 
  frequents 
  the 
  neigh- 
  

   borhood 
  of 
  gardens, 
  builds 
  in 
  the 
  city, 
  and 
  has 
  a 
  beautiful, 
  sweet 
  

   song. 
  It 
  is 
  a 
  little 
  bird, 
  often 
  found 
  sitting 
  on 
  the 
  top 
  of 
  cedar 
  

   trees 
  and 
  whistling 
  at 
  night. 
  On 
  Folsom 
  Street, 
  in 
  his 
  neighbor-
