ranges.  But  singularly  enough,  the  reviewer,  after  remarking 
upon  this  termination  of  the  Victorian  rocks,  refers  to  the  geo- 
logical work  of  Mr.  Julian  Woods  in  order  to  show  a  curious  ex- 
tension of  the  volcanic  action  which  is  to  be  "  traced  in  South 
Australia."  On  referring  to  the  extract,  however,  it  appears 
that  Mr.  Woods'  reference  is  not  to  South  Australia,  although 
it  relates  to  the  country  close  upon  its  border.  Mr.  Woods 
says  : — u  At  about  fifty  miles  east  of  Mount  Gambier,  on  the 
Victorian  side  of  the  boundary,  there  commences  an  immense 
volcanic  district,  which  may  be  traced  with  very  little  interrup- 
tion to  Geelong  by  immense  masses  of  trap  rock  and  extinct 
craters  of  large  dimensions.  This  kind  of  country  extends 
considerably  to  the  north  of  the  line,  and  it  is  underneath  the 
trap  rocks  there  found  at  the  junction  of  the  Silurian  slates  and 
ancient  granites  that  the  extensive  Australian  gold-fields  are 
worked." 
Another  extract  is  given  from  Mr.  Woods'  book,  embodying  a 
statement  similar  to  that  which  has  been  already  quoted  from 
Sir  Roderick  Murchison,  namely,  that  trap  rock  and  other  indi- 
cations of  volcanic  eruption  are  no  guide  to  the  presence  of 
gold,  unless  in  the  neighborhood  of  Silurian  rocks. — Journ.

The  manufacture  of  this  article  has  for  some  years  been 
monopolized  by  the  Taotai  (or  head  Mandarin)  of  the  island, 
and  its  sale  farmed  out  to  wealthy  natives.  In  former  years, 
a  good  deal  of  the  drug  was  clandestinely  produced,  and  smug- 
gled across  to  China,  where  it  was  largely  bought  up  by  foreign 
speculators,  and  carried  to  Hongkong  for  shipment  to  Calcutta, 
at  which  place  it  finds  the  readiest  market,  being  used  by  the 
natives  of  Hindostan  for  lubricating  the  body  and  other  domes- 
tic purposes.  But  now  its  monopoly  is  so  closely  watched  that 
almost  the  entire  trade  in  it  falls  to  the  lucky  individual  whose 
Chinese  agents  can  secure  the  monopoly.    This  bad  system  has
