378  AMERICAN  PHARMACEUTICAL  ASSOCIATION. 
The  spring  that  I  have  described  is  one  of  several  similar  ones,  on  the 
bank  of  a  small  brook  about  seven  miles  from  Los  Angeles. 
I  passed  up  and  down  the  stream  just  mentioned  for  a  short  distance,  on 
each  side,  and  found  one  or  two  natural  exposures  of  the  edges  of  nearly- 
horizontal  shales  of  a  light  color,  and  very  thinly  stratified.  The  lowest 
layers  were  charged  with  bitumen,  and  were  of  various  shades  of  brown  and 
black. 
These  shales  were  principally  siliceous,  and  were  overlaid  by  a  stratum 
of  pebbles  and  sand,  probably  beach-shingle. 
Bituminous  shales  are  also  exposed  in  the  harbor  of  San  Pedro,  near  the 
base  of  the  vertical  bluffs  of  sedimentary  formations  along  the  beach.  They 
have  a  dark  brown  or  black  color,  and  appear  to  be  argillaceous.  They 
emit  a  strong  bituminous  odor  when  struck  by  the  hammer. — Silliman's
